As the components WMC6300 Wireless Router Users Guide MeshView Users Guide MeshManager Users Guide Location Analyzer Users Guide 1 Setup and Deployment Guide System 1.5 Overview of the 1.5.1 Introduction MeshNetworks develops Mobile Broadband communications systems with meshed architectures. That is, each node can connect directly, or indirectly (by hopping through other nodes), with any other node in the network. The peer-to-peer nature of the mesh architecture combined with data rate control in each subscriber and infrastructure node in the network insures reliable delivery while providing increased network capacity through geographic reuse of the frequency spectrum. The network comprises four distinct elements:

Subscriber Devices (SDs) Wireless Routers (WRs) Mobile Internet Switching Controllers (MiSCs) Intelligent Access Points (IAPs) The overwhelming portion of the value that MeshNetworks provides is in the Wireless Modem Card (WMC). The WMC is used in Subscriber Devices as well as in the Wireless Router and Intelligent Access Point (IAP), both of which are infrastructure equipment. MeshNetworks provides a Mobile Internet Switching Controller (MiSC) which is assembled from industry standard equipment and conform to industry standards. MeshNetworks also provides the network applications which are required for proper operation and value extraction from the types of mobile internet system. Figure 1. Elements of the System All network elements are designed to support mobile applications. Subscriber Devices can be either mobile or fixed, while the remaining components are typically fixed. Wireless Routers and 2 Setup and Deployment Guide IAPs can be mounted on utility poles, light poles, traffic apparatus, billboards, and buildings. Their fixed positions allow the Subscriber Device to pinpoint its location within one second. WRs and IAPs can also be mobile, attached to emergency vehicles, utility vehicles, or fleet vehicles. It is important to note that the WMC technology within a Subscriber Device is identical to the WMC technology in Wireless Routers and IAPs. The system was designed to minimize the cost associated with deploying a mobile Internet with end user data access rates on the order of DSL or Cable Modem. The chosen metric of network efficiency for a data centric network is bits per second per Hertz per square kilometer per dollar (bps/hz/km2/$). This metric balances the user data rates, allocated bandwidth, coverage area, and cost. One of the most important factors in optimizing this metric is the choice of network architecture. 1.5.1.1 Subscriber Devices (SDs) The MeshNetworks Wireless Modem Card (WMC) is provided as a PCMCIA form factor device. The WMC is used with an off-the-shelf IP-enabled laptop, handheld computer, PDA, or entertainment device. These two devices together make up a Subscriber Device (SD). The WMC provides access to the fixed infrastructure network and other networks, such as the Internet, and it can also function as a Wireless Router and repeater for other SDs. SDs can therefore be a key part of the network infrastructure. Adding subscribers can effectively increase the number of Wireless Routers in the network, which increases the number of alternative paths that subscribers may utilize. This can reduce both the time and cost to deploy network infrastructure, while also increasing the spectral efficiency and therefore the capacity of the network. And because SDs can also operate in an ad hoc peer-to-peer mode, two or more SDs can form a network without the need for any fixed infrastructure. 1.5.1.2 Wireless Routers (WRs) The Wireless Router (WR) is a low-cost small-sized wireless device that is primarily deployed to seed a geographical area, extending the range between IAPs and subscribers, and to simultaneously increase the networks spectral efficiency. Wireless Routers provide a number of functions in the network, such as:

Range extension for Subscriber Devices and IAPs Hopping points for subscriber peer-to-peer networking Automatic load balancing Route selection Network capacity optimization through small packet consolidation Fixed reference for geo-location services The Wireless Router's small size and light weight allow it to be mounted almost anywhere. No towers are required. 3 Setup and Deployment Guide 1.5.1.3 Intelligent Ac i cess Po nts (IAPs) The Intelligent Access Point (IAP) is a low-cost shoebox-sized device that acts as the transition point from the wireless network to the wired core network and from there, through media gateways, out to the Internet. Each IAP offers up to 6 Mbps burst of data capacity to subscribers. IAPs support the 10/100 base-T Ethernet interface. Other interfaces are supported through commercially available media translation devices. If additional network capacity is required, more IAPs can be easily deployed -

without the need for extensive RF or site planning. The location of an IAP is non-critical due to the self-forming, self-balancing nature of MeshNetworks technology. IAPs provide functions such as:

Local mobility management of SDs Fixed reference for geo-location services Hopping points for subscriber peer-to-peer networking Transition point from the wireless to the wired portions of the network Route selection The IAPs small size and light weight allow it to be mounted anywhere power and network connectivity are available. No towers are required. IAP software can be updated via over-the-

wire downloads. 1.5.1.4 Mobile Internet Switching Controller (MiSC) The Mobile

(MiSC) provides connectivity between the IAPs and wired world, and hosts the networks management and provisioning functions. The MiSC is composed of off-the-shelf hardware components, such as LAN routers and application servers. MiSC software consists of both off-the-shelf software, MeshManager. The MeshManager software provides functions for the network such as:

Internet Switching Controller and MeshNetworks proprietary Subscriber provisioning, management, and authentication Configuration and fault management Network monitoring and reporting System 1.6 Operational View of the Figure 2 shows the different ways in which a subscriber can reach an IAP. It can connect directly, or hop through any number or combination of WRs and SDs. Additionally, if the subscriber wishes to execute a peer-to-peer application such as a file transfer, the subscriber can communicate directly, or through any combination of SDs, WRs, and IAPs. The ability to use ad hoc routing to forward traffic improves the scalability of the mobile wireless Internet. In particular, the ability for the user to accomplish a peer-to-peer application without the use of infrastructure has tremendous advantages. A significant problem in every mobile wireless network is backhaul. The architecture provides the ability to route traffic from 4 Setup and Deployment Guide applications through SDs and WRs without ever reaching an IAP or the wired Internet. This reduces the amount of backhaul required by enabling the SDs to accomplish the backhaul whenever the opportunity arises. This results in lower deployment costs, reduced backhaul, and lower operating expenditures. The service provider can provide the same level of service with less equipment by empowering the SDs with ad hoc networking capability.

Basic MiSC Configuration The following describes the parameters for setting up the network:

wireless devices must be within the same subnet. currently uses the non-routable 10.x.x.x (8 bit) subnet as defined in RFC 1918. All The IAP will use DHCP to obtain an address, and it must be returned a 10.x.x.x address. All MeshNetworks devices (other than the IAP) currently have fixed addresses of 10.0.x.x with a default gateway of 10.0.0.1. All Mesh devices (other than the IAP) currently expect a DNS server at the IP address 192.168.50.20. If a DNS server is not available at this address, subscriber device hosts will be unable to resolve web URLs. (This can be overcome by manually setting a DNS server address in the TCP/IP configuration for the subscriber device host. See Notes in Appendix B.) A VPN needs to be set up between the Network Operator and MeshNetworks Support group. 16 Setup and Deployment Guide 5.3 MiSC Assembly The MiSC hardware consists of commercial off-the-shelf components. The components are pre-configured with a basic configuration which requires minimal site-specific changes. The SMC switch arrives configured as two virtual LANs. The upper row of Ethernet ports is for the server subnet; the lower row of ports is for the wireless subnet. Unpack the SMC switch and mount as desired (either in a rack or on a table top). Connect the switch to a power source. Unpack the Cisco router labeled EdgeRTR and connect to a power source. Plug interface labeled 10BT Ethernet into the ISP router using a crossover Ethernet cable. Plug interface labeled 10/100 Ethernet into the SMC switch on port 1. Unpack the Cisco router labeled CoreRTR and connect to a power source. Plug interface labeled 10BT Ethernet into switch port 12. Plug interface labeled 10/100 Ethernet into the SMC switch on port 24. Unpack the SunBlade/MeshManager server and monitor and connect to a power source. Plug the network interface into any of the ports 2-11 on the SMC Switch. Connect Network Operator supplied computer running Window 2000. Plug the network interface into any of the ports 2-11 on the SMC Switch. Apply power to each of the devices. 5.4 Onsite Configuration of Routers 5.4.1 EdgeRTR Configuration The EdgeRTR must have on-site configuration done in order to connect to the Internet. Prior to performing the following steps, obtain the IP address, netmask, and default gateway for the public interface from the Internet Service Provider. These are shown as ip.ip.ip.ip, nm.nm.nm.nm, and gw.gw.gw.gw, respectively, in the instructions below. Also, obtain the IP address of the edgeRTR, it will be in the form of 172.xx.0.1. Telnet into the EdgeRTR from a computer connected to the server subnet. Use the address 172.xx.0.1 to connect to the EdgeRTR. Update the public IP information using the commands below Password:g0ld1. EdgeRTR>enable password:g0ld1. EdgeRTR#configure terminal Enter configuration commands, one per line. End with CNTL/Z. EdgeRTR(config)#interface Ethernet0 EdgeRTR(config-if)#ip address ip.ip.ip.ip mm.nm.nm.nm EdgeRTR(config-if)#exit EdgeRTR(config)#no ip route 0.0.0.0 0.0.0.0 EdgeRTR(config)#ip route 0.0.0.0 0.0.0.0 gw.gw.gw.gw EdgeRTR(config)#exit EdgeRTR#write memory 17 Setup and Deployment Guide Building configuration... EdgeRTR#copy running-config startup-config Destination filename [startup-config]? <return>

Building configuration... EdgeRTR#exit Connect the IAPs to any of the ports 13-23. 5.4.2 EdgeRTR TEST Use a computer connected to the switch (in either the server or wireless subnet) to ping to the ISP gateway IP. Next, test access to the Internet using a web browser. If this fails troubleshoot and retry. Obtain the VPN peer address and the appropriate pre-shared key for the VPN. 5.4.3 CoreRTR Configuration The CoreRTR must have on-site configuration performed to allow remote management of the wireless devices. During this exercise, the wireless subnet address of each of the wireless devices is mapped to a server subnet address. The wireless address is of the form 10.0.x.y. The value of x is obtained from the ID number found on the WMC, IAP or WR. The value of y is either 1 or 2; 1 indicates the host device and 2 indicates the transceiver. Note that a SD and IAP have both a host device and an transceiver, however a WR has a transceiver but not a host device. The server subnet address is of the form 172.a.b.c. The value of a is supplied by MeshNetworks as part of the VPN setup. The default value is 31. The value of b is the same as the x in the wireless address. Likewise, the value of c is the same as the y in the wireless address. For example, if there is an IAP with an id number of 69, the wireless subnet addresses for it will be 10.0.69.1 and 10.0.69.2. MeshNetworks supplies the second value in the server subnet access; this example will use the value of 22. The server subnet address corresponding to the wireless subnet address will be 172.22.69.1 and 172.22.69.2, respectively. The table below shows the address mapping which must be done for each IAP, WR and SD. A generic xx is used in the server subnet address since it is a site-dependent value. Telnet to the CoreRTR from a computer connected to the server subnet. Use the address 172.xx.0.2 to connect to the CoreRTR. Update the NAT information using the commands below:

Select Tools/Network Discovery Inside the Wired Range box select the Wildcard button, and enter the address 10.0.x.1 Inside the Wireless Range box, select the Wildcard button, and enter the address 10.0.x.2 Inside the Discovery Timeout box, use the default 3 second SNMP timeout Inside the Configuration Template box, select Autoconfigure. Select the desired templates for the IAP, WR and SD. Click the Start button. 3. The devices should now show up in the Device Tree pane on the left side of the window. 4. For each IAP and WR device in the Device Tree pane, double click on the address. This brings up the status in the detailed window. a. b. Click on the Configuration tab. Enter the appropriate data in the General box (Contact, Location, Host Name, Node Name) 5. If the geo location has not previously been entered, enter the latitude, longitude, and altitude in the Geo Location box. 6. Enter the IP address to send traps to in the SNMP box 7. For each SD device in the Device Tree pane, double click on the address. This brings up the status in the detailed window. Click on the Configuration tab. a. Enter the appropriate data in the General box. (Contact, Location, Host Name, b. Node Name, and Default IAP MAC Address). 20 c. d. Setup and Deployment Guide If Geo-location is to be demonstrated, then in the Geo Location box, select Enable Position Calculations, and select the default interval of 10 seconds. Select Enable Position Reporting, select the default interval of 10 seconds. Enter the map servers IP address. Note: If Geo-location will not be demonstrated, ensure that both Enable Position Calculations and Enable Position Reporting are not checked. Enter the IP address to send traps to in the SNMP box. 8. Close the Device Manager utility. Once the system components have been installed, there are two basic tests to verify correct operation the system. The first test is to perform ping tests to each device and the second test is to verify access the Internet. 5.6 Testing 5.6.1 Basic MiSC Tests To verify the basic connectivity of the MiSC, conduct the following from the MeshManager server:

Ping an IAP Ping the NAT Router Ping the Edge Router 5.6.2 Wireless System Tests From Device Manager, complete the following to verify correct operation of the system:

1. Ping the transceiver of the deployed IAPs (10.0.x.2) From the Device Manager drop down menu, select Preferences/Use Transceiver Address For each IAP in the device tree, right click and select Ping Device 2.

Ping the transceiver of each Subscriber Devices (10.0.x.2) From the Device Manager drop down menu, select Preferences/Use Transceiver Address For each SD in the device tree, right click and select Ping Device 5.6.3 Internet Test If the correct network setup:

system has been configured to access the Internet, complete the following to verify 1. From a SD, start the web browser and enter a URL such as http://www.MeshNetworks.com. 21 Setup and Deployment Guide Appendix A Site Selection/Deployment Guidelines General Guidelines A.1 The IAP location(s) should be selected first since they have the additional requirement of routing information back to the MiSC. This may be done via an Ethernet cable if the IAP and MiSC are located within 100 meters (the max length permitted for standard Ethernet) of each other. If the distance is greater than 100 meters, a mechanism for extending the Ethernet connection will be required, e.g., using fiber or T1. (MeshNetworks recommends T1 backhaul equipment from Net-

to-Net Technologies.) Once the IAPs have been placed, then the location of the WRs can be determined. Optimally, the devices should be distributed such that a SD has no more than 3 hops to an IAP. AC power must be available for both IAPs and WRs. Lastly, any local building/structure codes must be adhered to, as well as proper permits for placing devices on structures that are not owned by the Network Operator (e.g., light poles). MeshNetworks has developed the Location Analyzer tool to assist in the placement of infrastructure. This tool runs on a Win2000 SD. The tool collects and analyzes data, ultimately resulting in a deployment quality indication. Refer to the Location Analyzer documentation for information on configuring and using this tool. Antenna Guidelines A.2 The location of fixed infrastructure antennas must address proper antenna orientation, selection of elevation pattern for the specific locale, the avoidance of pattern distortion, and the impact of obscuration and non-line-of-sight paths. Polarization - Most of the antennas used in deployment will be vertically polarized. To maximize line-of-sight signal reception, both the transmit and receive antenna should be vertically oriented to avoid signal loss due to polarization mismatch. This applies to mobile and stationary antennas. For example, placing a magnetically mounted vehicle antenna on a curved portion of the vehicle roof so that its axis is not vertical risks a measure of signal loss at range, dependent upon the specific elevation pattern details, as discussed above. Local obstructions - Antennas should be mounted either above or below the plane of obstructions as shown in Figure 9. obstruction antenna antenna obstruction Figure 9. Antenna Mounting 22 Setup and Deployment Guide Low gain rubber duck antennas that are mounted directly to Mesh transceivers are designed for transmitting and receiving vertically polarized radiation. Hence, care must be taken to insure close-to-vertical orientation of these antennas to avoid substantial signal loss due to polarization mismatch. Additionally, attenuation sustained by use of these antennas inside vehicles can be as high as 10 dB. Typically, losses are in the 4 to 7 dB range if the antenna is above the metal can of the vehicle so that radiation and reception occur at window level. 23 Setup and Deployment Guide Appendix B Notes B.1 DNS Server The Wireless Modem Card returns a fixed IP address (192.168.50.20) to the SD host for the DNS server. If there is no DNS server in the wired network at this address, the SD host will be unable to resolve web URLs such as www.meshnetworks.com. To resolve this, the SD host must be manually configured with a DNS server IP address. Instructions to setup a Windows 2000 Host:

a. Start/Settings/Network and Dial-up Connections/Local Area Connection

(choose the Local Area Connection Corresponding to the Wireless Modem Card) Click on the Properties button. Highlight Internet Protocol (TCP/IP) in the Components window. Click on the Properties button. Click on the Advanced button. Click on the DNS tab Click on the DNS Add button. Enter the DNS Server IP Address provided by the local network administrator and then click the Add button. Click the OK button to close the Advanced TCP/IP Settings windows. Click the OK button to close the Internet Protocol (TCP/IP) Properties windows. Click the OK button to close the Local Area Connection Properties windows. Click the Close button to close the Local Area Connection Status window. i. j. k. l. This configuration should remain in the Windows 2000 host. b. c. d. e. f. g. h. Tera Term Pro B.2 Tera Term Pro is a free-ware software emulation program that has more capabilities than HyperTerminal

(which is provided with the standard Windows suite of applications). It is recommended that Tera Term be obtained so that in the event that MeshNetworks needs to assist the Network Operator with advanced debugging, there is a common utility in place. 24 Setup and Deployment Guide Appendix C License and Warranty Information IMPORTANT NOTICE C.1 PLEASE READ THE FOLLOWING CAREFULLY BEFORE INSTALLING OR USING THE PRODUCT.
