XL, XLE, XLV BreadCrumb User Guide Rajant Corporation 2.0 INTRODUCTION Rajant Corporation's (www.rajant.com) XL, XLE, XLV BreadCrumb integrates Ethernet and wireless IEEE 802.11b/g connectivity with mesh networking protocols. The network is mobile, self-integrating, self-meshing, self-healing, full-duplex and secure. An internal Li Ion rechargeable standby battery can power the unit when external power is unavailable. The focus is on flexibility, adaptability, and simplicity. The BC (BreadCrumb) is intended for rapid deployment of a broadband wireless network into a situation or hot zone. The BreadCrumb wireless network components utilize the IEEE 802.11b/g wireless networking standard to form a wireless mesh network. The network can be deployed as a stand-alone wireless network, or bridged to another network (such as the Internet) utilizing available reachback communication links (such as a DSL, cable, or satellite modem). NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. 2.1 WHAT IS A BREADCRUMB?
A Bread Crumb device is an 802.11b (Wi-Fi) Access Point specically designed for the following scenarios:
2.1.1 TEMPORARY WIRELESS NETWORKS Networks that must be established quickly and with minimal effort for short-term use.
(e.g., a network established to provide First Responder support at the site of a disaster). 2.1.2 MOBILE WIRELESS NETWORKS Networks in which the network infrastructure itself is mobile, in addition to client devices
(e.g., a convoy viewing a video stream from a UAV). 2.1.3 WIRELESS NETWORK EXTENSION Networks in which a wireless network must be quickly extended around or through obstacles that block wireless communications (e.g., urban canyon networks, tunnels/caves, etc.).

Rajant Corporation XL, XLE, XLV BreadCrumb User Guide 2.1.4 WIRED NETWORK EXTENSION Networks in which two or more wired LANs at different locations must be connected wirelessly (e.g., to securely connect combat service support computers with logistics bases). 2.1.5 ANY COMBINATION OF THE ABOVE Most BreadCrumb deployments include elements from more than one of the above scenarios. In many cases, BreadCrumb devices will perform all of the above tasks as shipped with no conguration necessary at all, providing an instant TAN -a Tactical Area Network. Moreover, because BreadCrumb devices use industry-standard 802.11b communications, client devices such as laptops or handheld computers require no special hardware, software, or conguration to access a BreadCrumb Wireless Network. 2.2 MOBILITY THROUGH MESHING The key component to a BreadCrumb Wireless Network is a technique known as Meshing. While this is generally handled automatically by BreadCrumb devices, complex deployment scenarios require a basic understanding of how BreadCrumb devices establish and maintain a mesh. 2.2.1 MESH A DEFINITION A mesh is a collection of network devices (in our case, BreadCrumb devices), each of which is connected to one or more other BreadCrumb devices. Data can move between BreadCrumb devices via these links, possibly passing through several intermediate BreadCrumb devices before arriving at its nal destination. The intelligence of a BreadCrumb Wireless Network is in how it adapts rapidly to the creation or destruction of the links in the mesh as devices are moved, switched OFF or ON, blocked by obstructions, interfered with by other devices, or otherwise affected. This adaptation takes place automatically and immediately as needed. Note: Although all BreadCrumb devices can be Access Points, most Access Points do not provide any meshing capabilities. Traditional Access Points simply allow wireless devices within range to connect to a wired network; they do not extend range through other Access Points. 2.2.2 BREADCRUMB DEVICES MESH BY CHANNEL AND ESSID Two BreadCrumb devices establish a mesh link to one another when they share both a radio channel and an ESSID. The 802.11b radios used by BreadCrumb devices support 11 different channels for communication, numbered 1-11. By default, each BreadCrumb device radio is on channel 1, or 11. Most BreadCrumb devices have two radios, using two of those channels. An ESSID is essentially a name for a wireless network. By default, BreadCrumb devices use the ESSID "breadcrumb".

XL, XLE, XLV BreadCrumb User Guide Rajant Corporation Example 1 Suppose you have three BreadCrumb devices, called A, B, and C. Each has two radios. BreadCrumb device As radios are on channels1 and 8, Bs are on 8 and 11, and Cs are on 1 and 11. All three BreadCrumb devices are using the default ESSID of "breadcrumb". Assuming that all three BreadCrumb devices are within radio range of one another, the network will be connected, Example 2 Now suppose that you change the ESSID of BreadCrumb device C to "lonely". The network will adjust to this change. Note that BreadCrumb device C can no longer communicate with A or B, and vice versa. BreadCrumb Table 1.

Rajant Corporation XL, XLE, XLV BreadCrumb User Guide 2.3 DESCRIPTION OF XL, XLE & XLV BREADCRUMBS 2.3.1 FEATURES The BreadCrumb XL is a long-range model, capable of 11 Mbits/s communications at distances of 7 miles (11.2 km) or more, and lower-speed communications at even greater range. As examples, BreadCrumb XLs have been rapidly deployed:
In Air Trafc Control towers On mountain tops On ships NOTE: The range-extending circuitry within a BreadCrumb XL is permanently tuned to 802.11b channels 1 and 11. Changing these settings may prevent your network from operating properly. The BreadCrumb XLV is identical to the BreadCrumb XL, with the exception that it also accepts unltered vehicle power (640 VDC) as a power source. This allows long-range communication within and among vehicle convoys and bases, and enables the bridging of widely spread networks by vehicles. As examples, BreadCrumb XLVs have been rapidly deployed:
In HMMWVs In Bradley Fighting Vehicles In trucks The BreadCrumb XLE is identical to the BreadCrumb XLV, except that it also includes an MPEG video encoder and an external BNC video connector. A composite video source can be connected to the BreadCrumb XLE and its video stream will be available to other devices on the BCWN. As examples, BreadCrumb XLEs have been rapidly deployed to provide video from:
Security cameras LRASSS (Long-Range Advanced Scout Surveillance System)

XL, XLE, XLV BreadCrumb User Guide Rajant Corporation 3.0 USING BCADMIN Note: Some portions of this section assume a working knowledge of TCP/IP networking, including DHCP, NAT, and DNS. While the network lay person may be able to perform some BCWN management tasks, it is recommended that network conguration be performed by experienced network administrators. BCAdmin is an application allowing an administrator to perform several tasks on a BreadCrumb Wireless Network, including:
Monitor its status Congure network-wide settings Congure individual BreadCrumb devices Graphically view the BCWN topology in real time BCAdmin typically runs on a laptop PC, but it can be run on any PC that has access to the entire BCWN. Versions are available for Microsoft Windows or Linux. Note: BCAdmin version 9.64 or higher is required to administer all firmware features that are covered in this manual.

Rajant Corporation XL, XLE, XLV BreadCrumb User Guide 3.1 SCREEN LAYOUT When BCAdmin is launched the screen will initially look like this: The large area on the left is the Topology Area, showing the current shape of the network at any given time. The Info Area to the right shows detailed information for BreadCrumb devices, client devices, and wireless links. Figure 5. BCAdmin Initial Screen at Startup Note: If your BCAdmin workstation does not have a network address in the 10.0.0.0/8 range, the large black area will instead be red, as in Figure 5, until you obtain such an address. A red Topology Area indicates that no communication with BreadCrumb devices is possible (this could be caused by no BreadCrumb devices being turned on, or the workstation has not associated with any BreadCrumbs).
- 16 -
XL, XLE, XLV BreadCrumb User Guide Rajant Corporation Figure 6. BCAdmin Screen at Startup (No Network Address in the 10.0.0.0/8 Range) When BCAdmin is able to communicate to a BCWN, the network topology is shown in the Topology Area, as below (your network will look different). 3.1.1 TOPOLOGY AREA The Topology Area shows the topology (logical shape) of your network as it changes. BreadCrumb devices and client devices (laptops, etc.) are shown graphically, as well as the links between them. Important: The Topology Area shows the logical layout of your network, not the physical layout. While there may be some correlation between the picture you see and the physical locations of your BreadCrumb devices and client devices, physical locations are not represented in this diagram. Tip: BCAdmin makes an effort to layout the Topology Area in an easily readable way, with a minimum of line intersections and superimposed boxes. Sometimes, however, the screen can get cluttered. BCAdmin provides two features to help cope with this, which may be used in combination:
A Play/Pause button in the toolbar below the File menu allows you to enable/disable continuous layout, effectively allowing you to lock BreadCrumb devices in place. BreadCrumb device and client device icons can be dragged to desired positions in the Topology Area using the mouse. The larger blocks in the Topology Area represent BreadCrumb devices. The smaller blocks with blue outlines represent client devices.
- 17 -
Rajant Corporation XL, XLE, XLV BreadCrumb User Guide Detailed information for a BreadCrumb device can be viewed in the Info Area by selecting the BreadCrumb device in the Topology Area. A BreadCrumb device can be selected by single-clicking it with your mouse. The selected BreadCrumb device will be highlighted with a dashed border. A description of the detailed information is provided later in this chapter. 3.1.2 ANATOMY OF THE BREADCRUMB BOX The following gure shows a close-up image of a BreadCrumb device as represented on the BCAdmin Topology Area. Figure 7. BreadCrumb represented on BCAdmin Topology Area 3.1.2.1. BREADCRUMB DEVICE NAME The BreadCrumb devices name is displayed in the upper-left area of the BreadCrumb Box. The name is assigned by an administrator using the process described in the Section called Conguring Individual BreadCrumbs. This allows the administrator to distinguish between multiple BreadCrumb devices in a BCWN. If the BreadCrumb device has no name assigned, its ID is used. The ID is a unique, alphanumeric, non-
editable string used internally by the BreadCrumb device. 3.1.2.2. TIME SINCE LAST UPDATE Each BreadCrumb device sends periodic information updates to BCAdmin, in intervals ranging from about 5 seconds to about 20 seconds. This number shows how long it has been, in seconds, since BCAdmin last heard from this BreadCrumb device. By default, BCAdmin will color the BreadCrumb Box red and make a sound if a BreadCrumb device has not sent an update for 60 seconds. This may simply be because a BreadCrumb device has been switched off, or its battery has died, or it may indicate a problem with the network, its deployment, the local radio environment, or other factors. 3.1.2.3. NUMBER OF PEERS A peer is simply another BreadCrumb device to which a BreadCrumb device has meshed. Data packets are automatically routed through peers as necessary by the BreadCrumb devices. 3.1.2.4. NUMBER OF CLIENTS A client is any IEEE 802.11b device that has associated with a BreadCrumb devices access point. Laptops, handheld computers, cameras, VOIP + Wi-Fi phones, etc. are examples of client devices.
- 18 -
XL, XLE, XLV BreadCrumb User Guide Rajant Corporation Tip: The amount of information displayed for each BreadCrumb device can be changed by right-
clicking on a BreadCrumb device and choosing Show More Detail or Show Less Detail. The detail level for the entire network can be changed via the View Menu at the top of the window. The above gure shows BCAdmins the default level of detail. 3.1.3 ANATOMY OF THE CLIENT BOX Client devices are represented in the Topology Area by a blue box containing the client devices MAC address, as pictured below. Figure 8. Client Device's MAC Address 3.1.3.1. CLIENT MAC ADDRESS/NICKNAME The MAC address or administrator-set nickname of the client device. Tip: An administrator can set nicknames for each client device. These nicknames are then displayed in the Topology Area instead of the MAC address. To set a nickname, right-click on the client device and choose Set Client Nickname. 3.2 ANATOMY OF A CONNECTION LINE If your BCWN has more than one BreadCrumb device, your Topology Area probably includes several lines connecting BreadCrumb boxes to clients and to one another. The color, style, and direction of motion (if any) of a line indicates its channel, speed, and direction as follows:

An asymmetric connection is a connection between two BreadCrumb devices in which each BreadCrumb device is transmitting at a different speed. When an asymmetric connection is made, the BCAdmin operator will see two lines of the same color connecting two BreadCrumb devices. The speeds will be represented in the line styles as specied in the BCAdmin Line Styles Legend above. Transmission direction of each link is represented by motion of the dots or dashes comprising the lines. (11 Mbps links are solid lines, so their direction in an asymmetric link is determined by elimination; its direction is simply the direction opposite the other link of the same color).

XL, XLE, XLV BreadCrumb User Guide Rajant Corporation 3.5 REACHBACK SETTINGS The Reachback tab contains controls for conguring the BreadCrumb devices interconnection with other networks, both wired and wireless:
Figure 14. BreadCrumb Properties Reachback Tab The available settings are:
3.5.1. REACHBACK INTERFACE This dropdown selects the network interface on the BreadCrumb device that will connect to the other network. Available options are (depending upon the BreadCrumb model and options):
a. None: Disables reachback. b. Ethernet Reachback will be congured to use the BreadCrumb devices Ethernet port (if any). Note: The reachback mode for eth1 is always bridge. Therefore, eth0 is the only port that can be changed. The type of Ethernet cable required depends upon the device to which you are connecting. If the BreadCrumb devices Ethernet port is to be connected to a hub or a switch, a conventional Ethernet patch cable (straight-through) should be used. If the BreadCrumb devices Ethernet port is to be connected directly to a device such as laptop or camera, a crossover cable should be used. Using the wrong cable will result in no connectivity. c. Radio2 Reachback will be congured to use the BreadCrumb devices second radio (if any).
- 25 -
Rajant Corporation XL, XLE, XLV BreadCrumb User Guide d. Radio2 (ad hoc) Reachback will be congured to use the BreadCrumb devices second radio (if any) in IEEE 802.11b ad hoc mode. 3.5.2. MODE This dropdown selects the type of reachback to congure. Available options are:
a. Automatic In Automatic Mode, the interface attempts to obtain an IPv4 address using DHCP. If it obtains an address, reachback is congured to use Gateway Mode; if it does not, reachback is congured to use Bridge Mode. b.Bridge In Bridge Mode, the reachback interface is congured to exist on the same network as the BreadCrumb devices other interfaces. Packets are forwarded into or ou tof the BCWN through this interface as necessary. c. Gateway In Gateway Mode, the reachback interface is congured to exist on a different network than the BreadCrumb devices other interfaces. Out bound NAT is congured so that any BCWN trafc destined for the reachback network appears to originate from the reachback interface. Any inbound trafc from the reachback network must be sent through a forwarded port (see the Section called Forwarding Settings) Unless the Alternate Gateway checkbox is checked (see below) the BreadCrumb will assign itself the additional IPv4 address of 10.0.0.1. d. Gateway (Ingress) In Gateway (Ingress) Mode, as in Gateway mode, the reachback interface is congured to exist on a different network than the BreadCrumb devices other interfaces. NAT, however, is congured in the direction opposite to that of Gateway Mode. Inbound trafc from the reachback network appears to originate from the BreadCrumb, and outbound trafc from the BCWN must be sent through a forwarded port (see the Section called Forwarding Settings for details) e. Disabled Disables reachback regardless of the selected interface. 3.5.3. ALTERNATE GATEWAY If the BreadCrumb is in Gateway Mode and this checkbox is not checked, the BreadCrumb device is considered a Primary Gateway and assigns itself the additional address of 10.0.0.1 (the gateway address provided by the BreadCrumb DHCP servers). There may be at most one Primary Gateway in a BCWN. Alternate Gateways do not assign themselves the 10.0.0.1 address, and provide their own addresses as a gateway to their own DHCP clients. Tip: If you are running a BCWN with multiple gateways, disable DHCP on all non-gateway BreadCrumb devices for a simple form of load-balancing. 3.5.4. ESSID For reachback using theRadio2 or Radio2 (adhoc) interfaces, this is the ESSID to which the BreadCrumb device will attempt to connect. 3.5.5. WEP KEY For reachback using the Radio2or Radio2 (adhoc) interfaces, this is the WEP key that will be used for the reachback connection. If a WEP key is not required for wireless reachback, leave this eld blank.

XL, XLE, XLV BreadCrumb User Guide Rajant Corporation 3.5.6. IP ADDRESS CONFIGURATION If 'Obtain an IP Address Automatically is selected for a Gateway Mode, the BreadCrumb device will obtain its IPv4 address on its reachback interface using DHCP. If Use the Following: is selected for a Gateway Mode, the following must be set manually:
a. IP Address b. Subnet Mask d. DNS Server (You may need to contact your network administrator in order to determine the c. Default Gateway correct settings.) 3.6 FORWARDING SETTINGS The Forwarding tab contains controls for conguring inbound NAT translation for BreadCrumb devices congured as gateways. Figure 15. BreadCrumb Properties Forwarding Tab
- 27 -
Rajant Corporation XL, XLE, XLV BreadCrumb User Guide To forward trafc through a BreadCrumb device in Gateway Mode or Gateway (Ingress) mode, you must know:
The IPv4 port(s) used by the forwarded trafc (e.g., 25 for SMTP, 80 for HTTP, etc.). The TCP protocol(s) used by the forwarded trafc (TCP and/or UDP). The IPv4 address to which the forwarded trafc is to be forwarded. The IPv4 port(s) at the destination address to which the forwarded trafc is to be forwarded (usually the same as the ports described above). The checkbox marked Enable species whether a particular forward conguration is active. This allows an administrator to pre-congure port forwards and selectively enable or disable them in the future. When a port forward has been congured, click the Add button to the right in order to add it to the current conguration. You may add as many port forwards as necessary to a BreadCrumb. Example: Port Forwarding Conguration for a Web Server Suppose a web server exists somewhere within a BCWN, and one of the BCWN BreadCrumb devices is serving as a Gateway connected to the Internet. In order to allow users on the Internet to access the web server, the following port forward conguration is required:
3.6.1 EXT. PORTS We will allow Internet users to access the internal web server using port 80, the default for web trafc. The external port range is therefore 80-80. 3.6.2 PROTOCOL Web trafc uses TCP, not UDP, so only the TCP checkbox should be checked. 3.6.3 IP ADDRESS This is the IP address of the web server on the BCWN. Note that this should be a xed IP address, as addresses obtained via DHCP can change overtime and thereby cause the port forwarding to fail. 3.6.4 TO PORTS The web server on the BCWN is listening for connections on port 80, so the port range should be 80-80. Once this port forward is enabled and saved to the BreadCrumb, Internet users may direct their web browsers to the Gateway BreadCrumb devices external IP address in order to reach the web server on the BCWN. 3.7 SECURITY Several levels of security are available for the BreadCrumb Wireless Network, which may be used individually or in combination with one another. We are constantly adding security features, so please contact your Rajant Account Representative if you have specic needs not included in this section.

XL, XLE, XLV BreadCrumb User Guide Rajant Corporation 3.7.1 WEP WEP (Wired Equivalency Protocol) was the rst scheme to provide security for IEEE 802.11 communications. Although since its release it has been determined to contain serious weaknesses, WEP remains an effective means to prevent casual eavesdropping. WEP settings are made network-wide; all BreadCrumb devices and wireless clients must agree on a WEP key in order to establish and maintain communications. To enable WEP on a BCWN, make sure that all of the BreadCrumbs to congure are visible in BCAdmin. Then choose Security, then WEP Settings to display the following window:
Figure 16. WEP Configuration Screen 3.7.1.1. WEP This dropdown allows the administrator to enable or disable WEP on all BreadCrumb devices currently visible in BCAdmin. 3.7.1.2. KEY A 40-bit or 104-bit hexadecimal key is specied in this eld. If this eld is left blank, WEP can be enabled using a previously congured key. 3.7.2 ACCESS CONTROL LISTS (ACLs) ABCWN may be congured with a network-wide Access Control List (ACL) to specify a list of devices to allow or disallow on the network. Each device communicating on the network (e.g., each BreadCrumb radio or laptop radio card) has a unique identier known as a MAC address. ACLs consist of lists of these addresses to specify permitted or forbidden devices. When enabled, the ACL may be in two modes: Deny by Default and Allow by Default. In Deny by Default mode, client devices and BreadCrumb devices are not permitted on the network unless they are listed in the Permitted Devices ACL. In Allow by Default mode, client devices and BreadCrumb devices are permitted on the network unless they are listed in the Forbidden Devices ACL. To edit the ACLs, click the ACL button in the toolbar. A window resembling the following will appear:
- 29 -
Rajant Corporation XL, XLE, XLV BreadCrumb User Guide Figure 17. Access Control Settings Window 3.7.3.1. POLICY This dropdown allows the administrator to select from three different policies:
No access control (allow all devices) This disables ACLs on the BCWN. Deny by default (allow only permitted devices) This policy only allows devices in the Permitted Devices, Administrators, or BreadCrumbs lists to connect to the BCWN. Allow by default (deny only forbidden devices) This policy denies BCWN access to all devices in the Forbidden Devices list. 3.7.3.2. ACL LIST TABS The Permitted Devices, Forbidden Devices, Administrators, and BreadCrumbs tabs allow access to individual device lists. 3.7.3.2.1 ADD/REMOVE BUTTONS These buttons allow individual devices to be added to or removed from the currently selected device list. Note: The BreadCrumbs and Administrators tabs in the ACL are automatically merged into the Permitted Devices and Forbidden Devices lists. Separate tabs are only provided in order to ensure that the administrator has fully considered the ramications of setting an ACL.

XL, XLE, XLV BreadCrumb User Guide Rajant Corporation Warning Be sure to include the BCAdmin workstation in the ACL so that you can continue administering the network!
3.7.3.2.2 Setting the Access ID The Access ID is a shared credential used by the IMCrypto client to negotiate encryption keys. All devices that are to communicate with one another must share a common Access ID. To set the Access ID on a BreadCrumb device, the BCAdmin workstation must be connected to the BreadCrumb device via the BreadCrumb devices Ethernet port. This is in order to prevent the transmission of the Access ID over an unsecured wireless connection that the Access ID will help to protect. Important: In order to communicate to a BreadCrumb device via the BreadCrumb devices Ethernet port, the BreadCrumb devices Ethernet interface must be placed into Bridge Mode in the BreadCrumb devices Reachback settings. If a BreadCrumb device does not have an Ethernet port, you cannot set its Access ID. If your BCAdmin workstation is connected to a BreadCrumb device via Ethernet, be sure that the BCAdmin workstations radio is disabled in order to guarantee that the Ethernet connection is in fact being used. To set the Access ID on a BreadCrumb device, open the General tab of its Properties window and click the button Change Access ID .You will be presented with a window resembling the following:
Figure 18. Set Access ID Window If the button is disabled, check to ensure that you have registered the IMCrypto client and that you are communicating with the BreadCrumb via its Ethernet interface. You must know the current Access ID in order to set a new one. The default Access ID on a BreadCrumb device is 0000000000000000 (16 zeros). You must supply the new Access ID twice in order to prevent the inadvertent setting of an unknown Access ID. Important: The Access ID change in a BreadCrumb device has an immediate effect. If you change the Access ID on a BreadCrumb device that has IMCrypto encryption already running, you will have to change your BCAdmin workstations Access ID to match it in order to communicate with the BreadCrumb device again. 3.7.4 ENCRYPTING WIRED TRAFFIC The BreadCrumb devices IMCrypto support includes the ability to encrypt trafc from a wired network provided that the BreadCrumb devices Ethernet interface is in either Gateway Mode or Gateway (Ingress) Mode. With IMCrypto enabled on a BreadCrumb device in one of these modes, encryption of wired trafc entering the wireless network and decryption of wireless trafc entering a wired network is completely automatic.

Rajant Corporation XL, XLE, XLV BreadCrumb User Guide 3.7.5 ZEROIZING THE ACCESS ID/FACTORY RESET The user will see the LED cycling through all seven (7) colors. When the LED finishes cycling through all seven (7) of its colors, it means that the zeroizing/factory reset is complete. Note: If there is no cycling of the colors, it means that a problem exists and that the unit should be returned to Rajant for repair. After the zeroize/factory reset, the unit will boot up automatically. The BreadCrumb Access ID and other settings can be erased remotely through BCAdmin. 3.7.6 AES-256 ENCRYPTION WITH OPENSSL Note: OpenSSLis currently undergoing FIPS 140-2 certication. For its current status, visit the Open Source Software Institutes website at http://www.oss-institute.org. Inter-BreadCrumb-device communication can be encrypted using OpenSSL in order to provide a secure wireless backbone. Trafc to or from wired devices and networks connected via a BreadCrumb devices Ethernet port and wireless devices associated with BreadCrumb devices is automatically encrypted as it passes through the BreadCrumb network. No client device conguration is necessary, although it is important to note that trafc between wireless clients and BreadCrumb devices should also be encrypted using WPA, WPA2, or WEP. SETTING THE KEY The key is a shared credential used by the BreadCrumb devices to encrypt and authenticate data. All BreadCrumb devices in a BCWN must share a common key. To set the key on a BreadCrumb device, the BCAdmin workstation must be connected to the BreadCrumb device via the BreadCrumb devices Ethernet port. This is in order to prevent the transmission of the key over an unsecured wireless connection that the key will help to protect. Important: In order to communicate to a BreadCrumb device via the BreadCrumb devices Ethernet port, the BreadCrumb devices Ethernet interface must be placed into Bridge Mode in the BreadCrumb devices reachback settings. If a BreadCrumb device does not have an Ethernet port, you cannot set its key. If your BCAdmin workstation is connected to a BreadCrumb device via Ethernet, be sure that the BCAdmin workstations radio is disabled in order to guarantee that the Ethernet connection is in fact being used. To set the key on a BreadCrumb device, open the General tab of its Properties window and click the button Change Access ID/Key .You will be presented with a window resembling the following:

You must supply the new Key twice in order to prevent the inadvertent setting of an unknown Key. Important: The Key change in a BreadCrumb device has an immediate effect. Changing the Key on a BreadCrumb device that is meshed with other BreadCrumb devices will cause it to stop communicating with those devices until their Keys are also updated to match. 3.7.7 ENABLING/DISABLING OpenSSL AES-256 ENCRYPTION AES-256 encryption is enabled and disabled on a BreadCrumb device using a checkbox on the General tab of the BreadCrumb Properties window. Unlike the Key, this setting maybe changed when communicating wirelessly with the BreadCrumb device. Important: Enabling and disabling encryption in a BreadCrumb device has an immediate effect. Changing this setting on a BreadCrumb device that is meshed with other BreadCrumb devices will cause it to stop communicating with those devices until their Keys are also updated to match. 3.7.8 ENCRYPTING WIRED TRAFFIC When encryption is enabled, all Ethernet-originated or Ethernet-destined trafc passing through the BCWN is automatically encrypted and decrypted as necessary, regardless of the Ethernet-connected BreadCrumb devices bridge or gateway setting. 3.7.9 ZEROIZING THE KEY The BreadCrumb Key and other settings can be erased remotely or with physical access to the BreadCrumb device by following the steps in the Section called Restoring Default Settings (Factory Reset) in Chapter 5.

- 35 -
Rajant Corporation XL, XLE, XLV BreadCrumb User Guide 4.0 DEPLOYING THE BREADCRUMB WIRELESS LAN 4.1 OVERVIEW OF BCWL DEPLOYMENT There are many factors which need to be taken into account when deploying the BreadCrumb Wireless LAN. Section 2.2 details some of the most commonly occurring environmental factors that will have a major impact on the performance of the BCWL. Section 2.3 details two common BCWL deployment configurations. Section 3.4 details guidelines and methodology needed to follow when deploying the BCWL. 4.2 DEPLOYMENT CONSIDERATIONS Commonly occurring environmental factors have a significant impact on performance and behavior of the BreadCrumb wireless LAN. Line-of-Sight obstructions, distance, weather, and device placement should all be considered when deploying a wireless LAN. The IEEE 802.11b/g wireless standard gracefully degrades as distance increases between nodes or as interference becomes present. This will be apparent by a data rate reduction between nodes. The goal in planning and deploying a BreadCrumb wireless LAN is to maximize data transfer rate between devices. The data rate can be maximized by taking into consideration all of the contributing factors that affect data throughput. 4.2.1 ADDRESSING When routing to another network or when using its own embedded DHCP servers, the BreadCrumb Wireless Network requires that wireless devices use IPv4 addresses in the Class A network 10.0.0.0/8 (that is, any address that begins with 10.). If you are not connected to another network, or if you are bridging to one rather than routing to it, your wireless client devices may have any address whatsoever. Important: Any devices running the BCAdmin management application must have an address in the 10.0.0.0/8 range. This may be in addition to other addresses the devices may have congured. 4.2.1.1 BREADCRUMB DEVICE ADDRESSES Each BreadCrumb radio has one IPv4 address in the Class A network 10.0.0.0/8. These addresses are assigned during manufacturing and cannot be changed in the eld. Rajant ensures during manufacturing that these addresses are not duplicated between any two BreadCrumb devices. Addresses assigned to BreadCrumb devices can be viewed using BCAdmin. 4.2.1.2 DHCP Each BreadCrumb device includes an embedded DHCP server. You may safely enable the DHCP servers of multiple BreadCrumb devices simultaneously, and it is in fact the most common case that all BreadCrumb devices in a BCWN run DHCP servers. Address conicts among DHCP clients are prevented by using the unique BreadCrumb device addresses assigned at the factory as a base. A BreadCrumb device determines its DHCP range as follows:
1. Start with the rst three bytes of the rst radios IPv4 address. Add a low-byte range of 10 to 210.
- 36 -
XL, XLE, XLV BreadCrumb User Guide Rajant Corporation 4.3 CHANNEL ASSIGNMENTS By default, BreadCrumb devices use channels 1 and 11 upon startup. BreadCrumb devices can be congured via BCAdmin to choose their radio channels automatically upon startup instead. With this feature enabled, combinations of channels 1, 8, and 11 are automatically chosen using a process designed to provide a robust mesh. In some cases, however, it is necessary to manually set the radios to specic channels as described below. 4.4 PHYSICAL PLACEMENT AND OTHER CONSIDERATIONS Commonly occurring environmental factors have a signicant impact on performance and behavior of the BreadCrumb Wireless Network. LOS (Line of Sight) obstructions, distance, weather, and device placement should all be considered when deploying a wireless network. IEEE 802.11b wireless operation degrades gracefully as distance increases between nodes or as interference becomes prominent. This manifests as a data rate reduction between nodes. The goal in planning and deploying a BreadCrumb Wireless Network is to maximize both coverage and the data transfer rate between devices. These can be maximized by taking into consideration all of the contributing factors described in this section. 4.4.1 LINE OF SIGHT Unobstructed LOS (Line of Sight) is critical for optimal performance of the BCWL. Partial LOS obstruction results in noticeable network performance degradation. Total LOS obstruction can result in complete loss of network connectivity. Elevating the device and external antenna will assist in providing better LOS. This can allow the radio waves to propagate over some possible obstructions. Unobstructed LOS is not necessary from every BreadCrumb and wireless client to every other BreadCrumb and wireless client. However, each device must have unobstructed LOS to the previous and subsequent device. Client connectivity will degrade, and if significantly dense, drop if LOS to a BreadCrumb can not be maintained. 4.4.2 DISTANCE There are many factors to determine acceptable distances to place BreadCrumbs when deploying a wireless network. If many devices are placed too closely together, it is possible that interference will degrade the performance of the system. Devices placed too far away or in RF shadows may experience total loss of connection. Device power is important in determining distances that the device will be effective. BreadCrumb XL, XLE, XLV operates at 600 mW. When placing a BreadCrumb, check the connection status to the most available device with BCAdmin. If the connection is poor or non-existent, attempt to relocate the BreadCrumb closer to the available device
- 37 -
Rajant Corporation XL, XLE, XLV BreadCrumb User Guide until acceptable connection is achieved. If poor or no connection is made at even relatively close distances, you should refer to the troubleshooting section of this guide. When the connection quality is found to be acceptable from BCAdmin, the distance of the BreadCrumb from the network can be increased until an optimal balance between distance, connectivity and tactical placement is achieved. BCAdmin is an administrative software application that can aid in deploying a BreadCrumb wireless LAN. Refer to section 2 of this manual regarding BCAdmin. 4.4.3 WEATHER Precipitation and fog also act as obstructions blocking the propagation of the wireless LANs radio waves. Light fog or precipitation may result in noticeable degradation of wireless LAN performance. Heavy precipitation or fog may result in severe performance degradation and possible loss of network connectivity. If the performance of a well functioning LAN is degraded by increasing weather conditions, it may be advisable to add BreadCrumb devices into the network to act as short haul repeaters to counter act the effects of the weather. An alternative is to move the devices closer together. 4.4.4 INTERFERENCE RF interference can degrade network performance and can come from many different sources. Interference can come from other BreadCrumb devices that are placed too closely together. Interference can come from many other RF devices such as microwave devices, cordless phone base stations, radio transmitters, other wireless LANS, jamming devices, etc. Metal surfaces such as fences and building can cause radio waves to be reflected, causing multipath interference. Plan the BreadCrumb wireless LAN to minimize the effects of RF interference. 4.4.5 PLACEMENT OF BCWL COMPONENTS The placement of BreadCrumb devices has a major impact on maximum effective range, and therefore network performance. The components must be elevated above the surrounding terrain to allow for adequate wave propagation. A device placed directly on the ground has a significantly reduced effective range. Elevating a device above the ground dramatically increased the maximum effective range. Rajant recommends elevating the components a minimum of 6 ft. above the surrounding surface. 4.5 DEPLOYMENT CONFIGURATIONS Sections 3.3.1 and 3.3.2 detail the two most common BCWL deployment configurations. In Section 3.3.1, the BCWL is deployed to provide wireless network connectivity throughout a chosen coverage area. In Section 3.3.2, the BCWL is deployed to provide wireless network connectivity reaching out into a chosen coverage area. Either of the deployment configurations illustrated can provide reachback connectivity to the Internet or other network by utilizing a Gateway BreadCrumb and available communication link (such as DSL, cable, or satellite modem).

As illustrated in Figure 22, the BCWL components are deployed outward from RCHPT01 in a straight line. The distances shown in Figure 22 are good starting points if the BCWL components are placed directly on the ground. Elevating the BCWL components, if possible, will allow for greater distance between the BCWL components, and greater coverage range for the wireless clients (follow the guidelines detailed in Section 3.4).

Each of the remaining BCWL components would provide continuity of the wireless network into the threat area. It should also be noted that this deployment configuration does not have to stretch out in a perfectly straight line. The BCWL component placement can be altered (following the guidelines and methodology in Section 3.4) to go around obstructions (such as buildings, terrain, etc.). 4.6 DEPLOYMENT GUIDELINES AND METHODOLOGY This section addresses the actual onsite deployment of the BCWL. While no means an exhaustive treatise, it is intended as a good source of guidelines and methodology for the successful deployment of the BCWL in the field. 4.6.1 DEPLOYMENT GUIDELINES Referring back to Section 3.2 (Deployment Considerations):
1. Placement of BCWL components a. Elevate the BCWL components whenever possible. i. Directly on the ground, the maximum distance between any two BCWL components is approximately 300 ft. Also, the maximum distance between a wireless client and the nearest BCWL component is approximately 300 ft. ii. Rajant recommends elevating each BCWL component a minimum of 6 ft. above the surrounding terrain for maximum range. Elevating the BCWL components, as little as 14 inches, has proven to increase the range out to approximately 600 ft. 2. Distance 3. Line of sight a. If you cannot elevate the BCWL components, they can only be approximately 300 ft. apart. Also, any wireless clients can be no farther than approximately 300 ft. from a BCWL component. a. Obstructions to line of sight block/absorb/deflect the wireless LANs radio waves, resulting in poor network performance or total loss of network connectivity. b. When placing the BCWL components, scan the area for LOS obstructions. Envision the BCWLs radio waves as a light beam. Look for obstructions that would result in shadows in the light beam, they will most likely weaken or block the BCWLs radio waves. 4. Weather clients. a. Light precipitation will reduce the range and performance of the BCWL components and wireless b. Heavy precipitation or fog will most likely result in extremely reduced range and frequent or total loss of network connectivity.

XL, XLE, XLV BreadCrumb User Guide Rajant Corporation 4.6.2 DEPLOYMENT METHODOLOGY The steps detailed in this section should assist you in successfully deploying the BCWL. 1. Scan the terrain on which the BCWL will be deployed. a. Determine the initial distances for Crumbs referring to the distance table of section 3.2.2. b. Note any LOS obstructions, and plan BreadCrumb placement to work around them. 2. Identify the PC on which BCAdmin will be run. a. This PC should have a wireless NIC, as you will need to carry it with you as you deploy the BCWL. i. Alternatively, the BCAdmin PC can be stationary with one person monitoring BCAdmin while another deploys the Crumbs. This method requires some form of communication
(radio, cell phone, etc.) between the two persons. 3. Determine the location of the first two Crumbs. 4. Power ON the device. 5. Wait approximately 90 seconds for the device to boot. 6. Power ON the BCAdmin PC. 7. Start BCAdmin. 8. The BCAdmin console should display the first BreadCrumb. 9. Install the batteries in the second BreadCrumb. 10. Proceed to the location for this BreadCrumb, observing the network in BCAdmin as you progress. a. If the BreadCrumb loses network connectivity before you reach its destination, backtrack until network connectivity is restored. The point at which network connectivity for this BreadCrumb is restored is most likely the farthest point in this direction at which you will be able to place this BreadCrumb. b. If you reach the destination without losing connectivity you can place it there. i. At this point, you may choose to proceed farther in an attempt to make optimal use of the available Crumbs. 1. If so, proceed until network connectivity is lost and then backtrack until network connectivity is restored for this BreadCrumb.

XL, XLE, XLV BreadCrumb User Guide Rajant Corporation 5.0 BREADCRUMB SOFTWARE MAINTENANCE 5.1 BREADCRUMB FIRMWARE 5.1.1 INTRODUCTION Each BreadCrumb relies on low-level software known as firmware for proper execution. Rajant periodically releases updated BreadCrumb firmware. The updated firmware must be obtained from Rajant. For a BreadCrumb to communicate with other BreadCrumbs or a BCAdmin client, the firmware version of the device must be compatible with the version of all other device firmware within the network, and with the version of BCAdmin running on a client PC!
Refer to the procedures to install and upgrade versions of BCAdmin and upgrade BreadCrumb firmware to ensure compatibility. 5.1.2 UPGRADING THE FIRMWARE For your hardware version 3 BreadCrumbs, download the rmware zip archive using the link provided by your Rajant Account Manager. 1. Create a new, empty folder and unzip the archive into it. 2. Copy the unzipped les (and only those les) onto an empty (no pre-existing les) ATA Flash Memory Card (of at least 16MB). The ash card may be directly purchased from http://www.magicram.com/shcrd.htm 3. Proceed with the ash instructions below. 5.1.3 FLASH UPDATE PROCEDURE FOR VERSION 3 SYSTEMS Note: BreadCrumb Wireless Network-specic parameters, like name and location, are reset to their default values after the upgrade. The user should record these and other parameters to reload into the BreadCrumb devices after the software installation procedure is completed. 1. 1. Turn OFF power to the BreadCrumb. 2. Remove the top PCMCIA card, leaving one radio card still installed in the bottom slot. In dual-radio BreadCrumb products, remove the top radio card. In single-radio BreadCrumb products, move the radio to the bottom slot. Plug the ash card, white label side up, into the top slot. Turn unit ON and observe the amber light ON on the radio card. (The green light sometimes goes ON, sometimes not.) Wait for the amber light to go out. TURN THE POWER OFF to the BreadCrumb. Remove the ash card, and replace the radio(s) to their original positions.

Rajant Corporation XL, XLE, XLV BreadCrumb User Guide 5.1.4 UPGRADING THE FIRMWARE 1) Obtain the desired firmware from Rajant Corporation for the version of your device board type. Create a directory named rajant on a USB storage device (of at least 256 MB) that must be VFAT formatted and copy the firmware file into the created rajant directory. 2) Turn off power to the BreadCrumb. 3) Attach the USB programming cable to the 15-pin connector. 4) Insert the USB storage device into the USB cable. 5) Turn on the BreadCrumb. 6) Wait approximately 3 seconds after the BreadCrumb has been turned on, then press the status button to have the BITE LED turned on. 7) Observe BITE to monitor progress. a) When the USB flash upgrade begins, the BITE LED will start blinking yellow, which identifies progress. per second. b) When the process nears completion, the blink rate will increase from once per second to several times c) If the flashing completes successfully, the LED will start rotating between red, green, blue, cyan, magenta, yellow and white colors. d) If an error condition is encountered, the LED will start repeating a particular sequence of long and short blinks in red indicating the error code. If this happens, note the error code. Manually power off and then back on the BreadCrumb, leaving the USB drive plugged in. This time, the BreadCrumb will go through a more reliable, failsafe flashing process, which has a greater chance of successful completion. If, during the failsafe flashing process another error occurs, note the new error code and apply for technical support. e) See APPENDIX A for a list of error codes 8) When complete, turn off power and remove USB programming cable. 5.2 BCADMIN MAINTENANCE 5.2.1 UPGRADING OR INSTALLING THE BCADMIN SOFTWARE Rajant periodically releases updated BCAdmin software. The updated BCAdmin software must be obtained from Rajant. The following procedure must then be performed on each of the BCWL Administrators PCs:
1. Obtain the desired version of BCAdmin from Rajant. 2. 3. Rajant as an executable file such as the one shown in Figure 23. Existing Versions of BCAdmin do NOT need to be uninstalled. Locate the BCAdmin software installation file and run it. It has typically been supplied by Figure 23. BCAdmin Software Installation File

XL, XLE, XLV BreadCrumb User Guide Rajant Corporation 5.3 PORT FORWARDING Port forwarding forwards all packets intended for one forwarding port on the gateway from the external networks to be routed on a specified port on one of the internal BreadCrumbs. It is a kind of traffic redirection to some other BreadCrumb, providing a particular service. An example of this would be a web server running on a BreadCrumb. For machines or BreadCrumbs, attempting to access this service, would know to send traffic to port 80 on the Gateway BreadCrumb. But in true sense, this BreadCrumb does not host the web service. Some other BreadCrumb has the service running. So, a port forwarding setting in the gateway helps forwarding all the traffic on its port 80 to the IP Address:port where the web server is running. 5.3.1 SETTINGS In BCAdmin, right-click on the BreadCrumb, where port forwarding is to be done and select Properties. Then select the Forwarding tab. Add the range of ports on this BreadCrumb, on which if any traffic is received, will be forwarded to some other BreadCrumb. For TCP or UDP traffic or both, select the corresponding check box. Then enter the IP address of the BreadCrumb where traffic is to be forwarded. Also enter the range of ports for that BreadCrumb. Check Enable to run this feature and the click the Add button. For example, if a video camera is attached to a BreadCrumb with IP address 10.217.60.10 and is running on port 4001, and if the traffic for this arrives on port 75, then the settings for this should be Ext. Ports: 75 75 TCP: unchecked UDP: checked IP Address: 10.217.60.10 To Ports: 4001 4001 Enable: checked

Rajant Corporation XL, XLE, XLV BreadCrumb User Guide 6.0 Troubleshooting 6.1 BREADCRUMB WIRELESS NETWORK 6.1.1 SPORADIC NETWORK CONNECTIVITY Table 7. Sporadic Network Connectivity Issues Problem As a BreadCrumb devices battery approaches exhaustion, network connectivity will become sporadic for the BreadCrumb device and its associated wireless clients. Light precipitation or fog beginning after initial deployment of the BCWN can result in sudden sporadic network connectivity for BreadCrumb devices and their associated wireless clients. As a wireless client moves around through the coverage area, LOS to the BreadCrumb device can become obstructed resulting in sporadic network connectivity for this wireless client. A wireless client that moves beyond the range of the BCWN will experience sporadic, and eventually complete, loss of network connectivity. A wireless client cannot join the network. Resolution Monitory battery usage and charge/replace batteries as necessary. Increase the density of the network by adding more BreadCrumb devices or by moving existing BreadCrumbs closer together. Train users to maintain LOS to known BreadCrumb device locations. Place BreadCrumb devices strategically to ensure coverage of areas through which users are expected to move. Drop more BreadCrumb devices as necessary to increase range. Ensure that BreadCrumb devices are powered on. Ensure that the wireless card in the client device (laptop) is enabled. This is usually indicated with a blinking light on the card. Ensure that the wireless card is in
"Infrastructure" or "Access Point" mode, and not in "Ad Hoc" mode. Scan for the ESSID
"breadcrumb" (or the ESSID that you set for the network) using the software accompanying your wireless card. Ensure that the wireless clients IP address settings are congured properly. Ensure that the WEP settings on the client device and BreadCrumb devices match. Ensure that the client device is not prevented from connectingby anACL. If the BreadCrumb devices comprising the network have AirFortress encryption enabled, ensure that the client does as well.

XL, XLE, XLV BreadCrumb User Guide Rajant Corporation 6.1.2 BREADCRUMB DEVICE CANNOT CONNECT TO BCWN Table 8. BreadCrumb Device Cannot Connect to BCWN Problem Resolution Discharged batteries can cause the BreadCrumb device to appear to power up, but not be able to establish connectivity to the BCWN. On rare occasions, the PCMCIA cards within a BreadCrumb device can work loose, resulting in the BreadCrumb devices not being able to establish connectivity to the BCWN. When using external antennas, faulty cable connections or crimped cables can result in difficulty establishing and maintaining network connectivity. When deploying the BCWN, ensure that the batteries should be fully charged. Open the BreadCrumb devices case and verify that the PCMCIA cards are securely seated in the PCMCIA slots. Check antenna cables and their connections to the BreadCrumb device.
