Harmony 8150 PCI Adapter Technical Description Document # 610.00xx PRODUCT:
The product is a WLAN adapter operating in the 5.15 5.35 GHz band with a maximum TX output power of 50mW. It is a circuit board assembly with a 62-pin power/data card edge connector and a pair of integral antennas. The peak gain for the two antennas is 3dBi and 1dBi, respectively. Refer to the manual for MPE statement. The device is design to fit into a universal PCI slot inside a PC. USER CONNECTIONS:
Data and power are provided through the 62-pin card edge connector. A unique antenna connector is provided for attaching each of the antennas to the adapter. TEST CONNECTIONS:
There are two 50 ohm RF ports on the PCA, one for each of the two antenna connections. Each antenna is terminated with a Radiall UMP3.0 lock-on plug. A slide-on version of the plug can be used during FCC certification for conducted measurements. INTERNAL CLOCK AND RF OSCILLATOR FREQUENCIES:
MAC/baseband Processor ASIC PCI BUS interface RF synthesizer 32MHz 33MHz PLL frequencies of 40, 80, or 160MHz derived from a 32 MHz oscillator 5180-5320MHz, 20MHz steps 4144-4256MHz 6216-6384MHz 20MHz TX and RX frequencies LO Leakage Mixer Product Baseband bandwidth SIGNAL FLOW:
Data is transferred through the 62-pin card edge connector (PCI bus) to the MAC/baseband processor which integrates the media access control (MAC), the baseband radio functions, A/D and D/A converters, transceiver control functions and a PCI/Cardbus interface. In transmit, the synthesizer tunes to one of the TX frequencies listed above. Data is initiated at the PCI interface, which is part of the MAC/baseband processor. Current outputs from the DAC of the MAC/baseband processor are low-pass filtered through the external reconstruction filter. The I and Q signals are converted to RF thru a dual-conversion architecture, from baseband to IF and from IF to RF signals. These signals are driven off-chip through a power amplifier, through the antenna switch, and to the antenna connector. In receive, the synthesizer tunes to one of the RX frequencies listed above. The receive signal path is from the antenna connector, through the antenna switch, a band pass filter, an LNA, a receive balun, and to the integrated transceiver IC. Inside the transceiver IC, the RF mixer converts the output of the on-chip LNA to an intermediate frequency. The IF mixer converts this signal down to baseband I and Q signals. The I and Q signals are low-pass filtered by the external channel select filters, and amplified by a baseband PGA controlled by digital logic. The baseband signals continue through external anti-alias filters before being sent to the ADC of the MAC/baseband processor. Data at the PCI interface of the MAC/baseband processor is processed and then sent to the PCI interface of the PC.

Introduction 4 System Requirements To begin using the Harmony 802.11a PCI Card, you must have the following minimum requirements:
A computer that meets the following specifications:
Windows 2000, Windows Millennium Edition (ME), or Windows 98 Second Edition (SE) installed PCI (Peripheral Components Interconnect) expansion slot At least 64 MB of memory A 300 MHz processor or higher At least one other IEEE 802.11a-compliant device 5 Chapter 2 Installation This chapter describes how to install the Harmony 802.11a PCI Card and software in a computer running Windows 2000, Windows Millennium Edition (ME), or Windows 98 Second Edition (SE). Pre-installation Considerations Review the following pre-installation considerations before installing the Harmony 802.11a PCI Card. Regulatory Warnings FCC Guidelines It is the responsibility of the installer and users of the Harmony 802.11a PCI Card Model 8150 to guarantee that the antennas are operated at least 20 centimeters from any person. This is necessary to insure that the product is operated in accordance with the RF Guidelines for Human Exposure which have been adopted by the Federal Communications Commission. Radio Frequency Interference Requirements The Harmony 802.11a PCI Card Model 8150 operates in the frequency range of 5.15 to 5.35 GHz; it is restricted to indoor use due to its operation in the 5.15 to 5.25 GHz frequency range. FCC 15.407(e) requires that the device be used indoors in the frequency range of 5.15 to 5.25 GHz to reduce the potential or harmful interference to co-channel Mobile Satellite systems. Therefore the device should be used indoor only for channel 36, 40, 44, and 48 and when 2X mode is enabled, channel 42 and 50. High power radars are allocated as primary users of the 5.25 to 5.35 GHz and 5.65 to 5.85 GHz band. These radar stations can cause interference with and/or damage the Harmony 802.11a PCI Card. Installation 6 Windows ME and Windows 98 SE Installation CD Requirement Before beginning the installation of the 802.11a PCI Card, confirm that you have a Windows 98 SE or Windows ME installation CD available (depending on the computers operating system). Windows 98/ME users may be prompted to insert a Windows CD during the installation. You should not need a Windows CD when installing an 802.11a PCI Card in a Windows 2000 computer. If you do not have a Windows 98/ME CD, it is possible that you already have the Windows installation files on your hard disk. These Windows installation files are known as Windows Cabinet or CAB files. The Cabinet files are commonly located in C:\WINDOWS\OPTIONS\INSTALL\ or C:\WINDOWS\OPTIONS\CABS\. Note:
Windows 98/ME users may need the Windows CD or Cabinet files to com-
plete the installation of the 802.11a PCI Card. Proxim recommends that you do not proceed with the installation until you have confirmed that you have one of these Windows installation media available.

(described in Chapter 5) to configure the card and determine if it is communicating with other 802.11a devices. If you have one or more 802.11a Access Points, configure the Harmony 802.11a PCI Cards Network Mode setting to Infrastructure. If your network consists of only 802.11a client adapters, configure the Network Mode setting to Ad Hoc. For more information on Ad Hoc and Infrastructure networks, see Chapter 3 beginning on page 13 and Network Mode on page 18. Related Topics See Chapter 4 beginning on page 17 for a discussion of the 802.11a configuration parameters. Refer to Chapter 5 beginning on page 23 for information on how to use the Harmony Utility. See Configuring Networking Clients and Protocols on page 40 for information on how to configure a networking protocol like TCP/IP (so you can configure the 802.11a PCI Cards IP settings). 13 Chapter 3 Wireless Topologies Harmony wireless products look and operate similar to Ethernet products. The only difference is that a radio replaces the wire between various nodes. This means that all of your existing applications that operate over Ethernet will work with Harmony without any special wireless networking software. The Harmony 802.11a PCI Card supports several network topologies, which are described in this chapter. Ad Hoc With wireless LANs, one or more computers easily establish an ad hoc network when the units are in range of each other. Each computer can dynamically connect and reconnect to the others with no additional configuration, using off-the-shelf peer-to-
peer network operating systems, as illustrated in Figure 1. Figure 1 Ad Hoc To use the Harmony 802.11a PCI Card as a member of an Ad Hoc network with other 802.11a-compatible cards, configure the card to operate in Ad Hoc mode. See Chapter 4 for information on how to configure the 802.11a parameters. Wireless Topologies 14 Infrastructure Many companies have an existing Ethernet or wired LAN infrastructure and want to be able to extend that capability to wireless nodes. This is accomplished by installing a Harmony Access Point Controller and one or more Harmony 802.11a Access Points on the Ethernet network. The Harmony Access Point Controller and 802.11a Access Points work together to provide wireless clients with access to network resources. Connecting to a Single AP Figure 2 depicts a Harmony network that uses a single Access Point (AP). Figure 2 Single AP Wireless Topologies 15 Roaming Between Multiple APs For larger environments, a Harmony 802.11a client devices may roam from one Harmony 802.11a Access Point to another while maintaining the same network connection. The 802.11a Access Points establish coverage areas or cells similar in concept to those of a cellular phone network. The mobile clients will connect to any 802.11a Access Point that is within range. Figure 3 Roaming Each Harmony 802.11a Access Point within a roaming network must have a unique, independent Channel, but all must have the same SSID and WEP Keys (if WEP is enabled). Mobile clients, equipped with Harmony 802.11a CardBus Cards or PCI Cards, are configured to operate in Infrastructure mode and have the same SSID and WEP Keys as the Access Points. Alternatively, the mobile client may use an SSID of any to associate with any available Access Point, regardless of the APs SSID. Wireless Topologies 16 As the mobile client seamlessly switches from cell to cell, its network connectivity is preserved. The user can move freely between the Harmony 802.11a Access Points in the network. When the roaming client leaves the transmission range of one 802.11a Access Point, the software automatically polls the other 802.11a Access Point(s) in the same Extended Service Set (ESS) to continue the network connection. Note:
The cells must overlap to ensure that there are no gaps in coverage so that the roaming client will always have a connection available. See Figure 3 for an example of a roaming Infrastructure network. In addition, Harmony 802.11a Access Point may be installed on different IP subnets from the AP Controller, allowing mobile users to roam across routers. For more information on the Harmony AP Controller and Access Points, refer to the Harmony Access Point Controller Model 7560 Users Guide. Guidelines for Roaming A Harmony 802.11a client can only roam between Harmony 802.11a Access Points. An 802.11a client cannot communicate with Harmony 802.11b or OpenAir Access Points. All Harmony 802.11a Access Points must have the same SSID. All workstations with Harmony 802.11a client adapters installed must use either an SSID of any or the same SSID as the Access Points that they will roam between. If WEP encryption is enabled, then all 802.11a Access Points and clients must use the same encryption level and WEP Key(s) to communicate. The Access Points cells must overlap to ensure that there are no gaps in coverage and to ensure that the roaming client will always have a connection available. All Access Points in the same vicinity should use a unique, independent Channel. Access Points that use the same Channel should be installed as far away from each other as possible to reduce potential interference. 17 Chapter 4 Configuration Parameters This chapter provides information on the 802.11a wireless standard and describes the Harmony 802.11a PCI Cards configuration parameters. The IEEE 802.11a Specification In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11 standard for wireless devices operating in the 2.4 GHz frequency band. This standard includes provisions for three radio technologies: direct sequence spread spectrum, frequency hopping spread spectrum, and infrared. Devices that comply with the 802.11 standard operate at a data rate of either 1 or 2 Mbps. In 1999, the IEEE modified the 802.11 standard to support devices operating in the 5 GHz frequency band, calling this new standard 802.11a. 802.11a devices are not backwards compatible with 2.4 GHz 802.11 or 802.11b devices. 802.11a radios use a radio technology called Orthogonal Frequency Division Multiplexing (OFDM) to achieve data rates of up to 54 Mbps. In addition, the Harmony 802.11a PCI Card supports 2XTM Mode. This mode is not part of the IEEE 802.11a specification but it allows data rates of up to 108 Mbps. See 2X Mode on page 19 for details. Configuration Parameters 18 802.11a Software Parameters The following configuration parameters are available for the Harmony 802.11a PCI Card. Refer to Chapter 5 for instructions on how to change these configuration settings using the Harmony Utility. Network Mode Network Mode configures the Harmony 802.11a PCI Card to operate in either Ad Hoc mode or Infrastructure mode. This parameters default setting varies based on the driver version installed. When set to Ad Hoc, all Harmony 802.11a devices must have the same SSID, Channel, and WEP Keys (if WEP is enabled) to communicate. An Ad Hoc network is a wireless network that consists of only 802.11a client adapters (i.e., a network that does not have an Access Point). When set to Infrastructure mode, an 802.11a PCI Card must have the same SSID and WEP settings (if WEP is enabled) as the Access Points on the network to communicate. An Infrastructure network is any network that includes one or more 802.11a Access Points. SSID The SSID (Service Set ID), which is also referred to as the ESSID (Extended Service Set ID), is a text string that all members of the same 802.11a network share. The SSID may be up to 32 alphanumeric characters long, including spaces. Also, when configured to any, a Harmony 802.11a PCI Card can communicate with any available Access Point regardless of the Access Points SSID. In an Infrastructure network, the SSID must match on all Harmony 802.11a Access Points and 802.11a clients (unless the clients SSID is any). Devices that do not share the same SSID cannot communicate. In an Ad Hoc network without an Access Point, each 802.11a device must have the same SSID to participate in the network. A node cannot use the any SSID to join an Ad Hoc network. Configuration Parameters 19 Power Saving Mode The Harmony 802.11a PCI Card supports optional power management to conserve battery life. Power Saving Mode is only available if the PCI Card is operating in Infrastructure mode. When Power Saving Mode is set to Normal or Maximum, the Harmony 802.11a PCI Card enters a doze mode where the card becomes inactive and only wakes up periodically to receive control messages from the Access Point. The card wakes up more often in Normal mode than in Maximum mode so a card in Normal mode will respond sooner to network requests than a node in Maximum mode. However, Maximum mode draws less power than Normal mode. When an Access Point receives a packet destined for a dozing client, it buffers the packet and includes a notification within its control message to alert the client that a packet is waiting for it. Once the card receives the control message, it polls the Access Point to request that the buffered packet be sent to it. 2X Mode The Harmony 802.11a PCI Card supports 2XTM mode, a high-speed operating mode that can provide data rates of up to 108 Mbps, twice the speed of standard 802.11a devices. By default, 2X mode is disabled. When 2X mode is disabled, the PCI Card complies with the IEEE 802.11a standard, can operate on one of eight Channels, and can achieve speeds of up to 54 Mbps. When 2X mode is enabled, the PCI Card does not comply with the IEEE 802.11a standard, can operate on one of three Channels, and can achieve speeds of up to 108 Mbps. Note:
You must configure all devices in the same network to use 2X mode. A device in 2X mode cannot communicate with a device in 802.11a mode. Configuration Parameters 20 Channel 802.11a devices spread a radio signal over a range of frequencies. The IEEE 802.11a specification allocates the available frequencies in the 5 GHz band into a series of operating Channels that are identified by a Channel number and a center carrier frequency. A PCI Card configured for Infrastructure mode receives a Channel assignment from its Access Point. You cannot configure the Channel for a PCI Card configured for Infrastructure mode. For an Ad Hoc network, nodes must use same Channel in order to communicate. You can configure the PCI Card to scan multiple Channels to locate an Ad Hoc network or you can configure the card to use a specific Channel. See Station Configuration on page 26 for details. Note that if you wish to install multiple Ad Hoc networks in the same vicinity, Proxim recommends that you configure each network with a unique Channel to avoid interference between networks. The number of available Channels varies by country. In the United States, the Harmony 802.11a PCI Card with integral antennas can use eight Channels in 802.11a-compliant mode: Channel 36 (5.18 GHz), Channel 40 (5.20 GHz), Channel 44 (5.22 GHz), Channel 48 (5.24 GHz), Channel 52 (5.26 GHz), Channel 56 (5.28 GHz), Channel 60 (5.30 GHz), and Channel 64 (5.32 GHz). In the United States, the Harmony 802.11a PCI Card with integral antennas can use three Channels in 2X mode: Channel 42 (5.21 GHz), Channel 50 (5.25 GHz), and Channel 58 (5.29 GHz). Note:
See Radio Frequency Interference Requirements on page 5 for important regulatory information concerning Channel selection. Maximum Send Rate The IEEE 802.11a specification supports eight data rates: 54 Mbps, 48 Mbps, 36 Mbps, 24 Mbps, 18 Mbps, 12 Mbps, 9 Mbps, and 6 Mbps. Harmonys 2X mode supports eight data rates: 108 Mbps, 96 Mbps, 72 Mbps, 48 Mbps, 36 Mbps, 24 Mbps, 18 Mbps, and 12 Mbps. As a mobile client travels further and further away from an 802.11a Access Point (when in Infrastructure mode) or from other 802.11a nodes (when in Ad Hoc mode), the data rate automatically decreases in order to maintain a usable radio connection. In an Infrastructure network a client that is close to an Access Point may operate at 108 Mbps, but a client that is far away from the Access Point may operate at 12 Mbps. By default, the Harmony 802.11a PCI Card automatically adjusts the transmit rate depending on the mode of operation (802.11a-compliant or 2X). However, you can manually set a maximum rate that the PCI Card will use. For example, if you configure the Max Send Rate for 36 Mbps, the Harmony 802.11a PCI Card will only operate at speeds of 36 Mbps or less. Configuration Parameters 21 RTS/CTS The 802.11a standard supports optional RTS/CTS communication based on packet size. By default, RTS/CTS communication is disabled. Without RTS/CTS, a sending radio listens to see if another radio is already using the medium before transmitting a data packet. If the medium is free, the sending radio transmits its packets. However, there is no guarantee that another radio is not transmitting a packet at the same time, causing a collision. When RTS/CTS occurs, the sending radio first transmits a Request to Send (RTS) packet to confirm that the medium is clear. When the receiving radio successfully receives the RTS packet, it transmits back a Clear to Send (CTS) packet to the sending radio. When the sending radio receives the CTS packet, it sends the data packet to the receiving radio. The RTS and CTS packets contain a reservation time to notify other radios that the medium is in use for a specified period. This helps to minimize collisions. While RTS/CTS adds overhead to the radio network, it is particularly useful for large packets that take longer to resend after a collision occurs. You may configure a Harmony 802.11a PCI Card to never use RTS/CTS (i.e., disable RTS/CTS) or to use RTS/CTS for packets over a certain size. For example, if the RTS/CTS Threshold is set to 1000 Bytes, then a sending radio will use RTS/CTS before transmitting any packet 1000 Bytes or larger. The RTS/CTS Threshold parameter supports a range between 1 and 2345 Bytes. When set to 1, a sending radio will use RTS/CTS before transmitting any packet. Wired Equivalent Privacy The IEEE 802.11a standard specifies an optional encryption feature, known as Wired Equivalent Privacy or WEP, that is designed to provide a wireless LAN with a security level equal to what is found on a wired Ethernet network. WEP encrypts the data portion of each packet exchanged on the 802.11a network using a 40-bit, 128-bit, or 152-bit encryption algorithm to prevent unauthorized devices from intercepting confidential data. To use WEP Encryption, all 802.11a devices within the same Extended Service Set
(ESS) or Ad Hoc network must have WEP enabled and must have the same WEP Keys. A device that has the wrong WEP Keys or does not have WEP enabled will not be able to exchange data with the network. Configuration Parameters 22 WEP Key An 802.11a device with WEP enabled uses a WEP Key to encrypt and decrypt information. If the WEP Keys do not match on two radios, no data communication will take place between these devices. The Harmony 802.11a PCI Card can support up to four WEP Keys (all four Keys must have the same Key Size). The Harmony 802.11a PCI Card can decrypt information that was encrypted with any of its four WEP Keys. A Harmony 802.11a PCI Card will only use the Default Key to encrypt outgoing information. For 40-bit encryption, a WEP Key is 10 hexadecimal digits (0-9 and A-F); for 128-bit encryption, a WEP Key is 26 hexadecimal digits (0-9 and A-F); and for 152-bit encryption, a WEP Key is 32 hexadecimal digits (0-9 and A-F). Note:
When WEP is enabled, Proxim recommends that you configure all 802.11a devices in the Extended Service Set with the same WEP Keys in the same order (but the devices not need to use the same default Key). 23 Chapter 5 Harmony Utility The Harmony 802.11a PCI Card includes a software utility that simplifies the management and configuration of a PCI Card. Chapter 2 describes how to install the utility. This chapter describes how to use the Harmony Utility after it has been installed. Status Monitor Icon After you have installed the Harmony Utility, the Status Monitor icon will appear in Windows System Tray.

Association Information The Association Information screen, shown in the example below, displays information about the PCI Cards connection with the 802.11a network. The Association Information screen reports the following statistics:
Association State: This field reports if the card is communicating with an Access Point (AP) or Ad Hoc network. When communicating with an AP, this field reports ASSOCIATED AP and displays the APs physical address. When communicating with an Ad Hoc network, this field displays JOINED AD HOC MODE. If the card cannot locate an AP or Ad Hoc network, this field displays NOT JOINED. Harmony Utility 25 Station Address: This field displays the PCI Cards physical address (also known as MAC address). This address is configured at the factory. Channel (Freq): This field displays the current Channel and center frequency that the PCI Card is using. See Channel on page 20 for details. Send Rate: This field reports the PCI Cards current transmit rate. Receive Rate: This field reports the data rate at which the PCI Card is currently receiving packets sent by another 802.11a device. Send Signal Strength: The Signal bar displays the signal strength for the last acknowledgment (ACK) received by the PCI Card. Signal strength is reported in decibels (dB). The color-coded chart below the Signal bar indicates the relative strength of the signal: a signal in the red or orange section indicates a weak con-
nection; a signal in the yellow or light green section indicates a good connection;
a signal in the darker green section indicates an excellent connection. Instantaneous Packets/Sec Sent: This statistic displays the current rate at which the PCI Card is transmitting packets to another 802.11a device. This information is represented as the number of packets sent per second by the card and is plot-
ted on the graph located below the Packets/sec field. Note that this statistic will remain zero unless the PCI Card is transmitting data to another 802.11a device. Average Packets/Sec Sent: This statistic displays the average number of packets transmitted by the PCI Card each second since the Configuration Utility was launched. Receive Signal Strength: The Signal bar displays the signal strength for the last packet received by the PCI Card. RSSI is reported in decibels (dB). The color-
coded chart below the Signal bar indicates the relative strength of the signal: a signal in the red or orange section indicates a weak connection; a signal in the yellow or light green section indicates a good connection; a signal in the darker green section indicates an excellent connection. Instantaneous Packets/Sec Received: This statistic displays the current rate at which the PCI Card is receiving packets from another 802.11a device. This infor-
mation is represented as the number of packets received per second by the card and is plotted on the graph located below the Packets/sec field. Note that this statistic will remain zero unless the PCI Card is receiving data from another 802.11a device. Average Packets/Sec Received: This statistic displays the average number of packets received by the PCI Card each second since the Configuration Utility was launched.

Click OK to save the WEP Keys. Select one of the Keys you configured as the Default Key. Harmony Utility 30 In the following example, Key 3 is the Default Key. The Harmony 802.11a PCI Card can decrypt information that was encrypted with any of its four WEP Keys but it will only use the Default Key to encrypt outgoing information. Click Apply or OK to save the new WEP settings. If you need to change a WEP Key at a later date, click Configure WEP Keys and enter one to four new WEP Keys. Note that any Keys you entered previously will not be visible (stars appear in place of the digits). 9. 10. See Wired Equivalent Privacy on page 21 for more information on the WEP parameters. Harmony Utility 31 Network Traffic Statistics Click the Statistics tab to view information about the number of packets sent and received by the PCI Card, as shown below. The default Statistics screen displays the following statistics:
Unicast Packets Sent:::: This statistic reports the number of packets transmitted by the PCI Card that were destined for a single network node. Multicast Packets Sent: This statistic reports the number of packets transmitted by the PCI Card that were destined for more than one network node. Unicast Packets Received: This statistic reports the number of packets received that were destined only for the PCI Card. Multicast Packets Received:::: This statistic reports the number of packets received that were destined for more than one network node. You can view additional statistics by clicking Advanced Statistics, as shown on the next page. Harmony Utility 32 The advanced Statistics screen displays the following additional statistics:
Unicast Bytes Sent: This statistic reports the total number of bytes contained in the unicast packets transmitted by the PCI Card. Multicast Bytes Sent: This statistic reports the total number of bytes contained in the multicast packets transmitted by the PCI Card. Single Retries: After the PCI Card sends a packet, it waits for an acknowledgment from the receiving radio to confirm that the packet was successfully received. If an acknowledgment is not received within a fixed period of time, the PCI Card will retransmit the packet. This statistic reports the number of packets that required one retry before the PCI Card received an acknowledgment. Multiple Retries: This statistic reports the number of packets that required more than one retry before the PCI Card received an acknowledgment. Transmit Retry Limit: This statistic reports the number of packets that were not successfully transmitted because the PCI Card did not receive an acknowledg-
ment within the maximum number of retries. Harmony Utility 33 Last ACK RSSI: This statistic reports the RSSI (Received Signal Strength) for the last acknowledgment (ACK) received by the PCI Card. RSSI is reported in decibels
(dB) and typically ranges from 0 to 75. In general, an RSSI less than 15 indicates a weak signal and an RSSI greater than 30 indicates a strong signal. ACK Errors: This statistic reports the number of unicast transmit attempts for which no acknowledgement (ACK) was received. CTS Errors: This statistic reports the number of Clear To Send (CTS) errors. When the PCI Card uses RTS/CTS before transmitting a packet, it first sends a Request to Send (RTS) message to the packets recipient. The packets recipient then returns a CTS message to the PCI Card. When the PCI Card receives the CTS, it sends the packet to the recipient. However, if the PCI Card does not receive a CTS within a fixed period of time, it will resend the RTS. After a fixed number of retries, the PCI Card will record a CTS Error if a CTS has not been received. Unicast Bytes Received: This statistic reports the total number of bytes contained in the unicast packets received by the PCI Card. Multicast Bytes Received: This statistic reports the total number of bytes con-
tained in the multicast packets received by the PCI Card. WEP Undecryptable: This statistic displays the number of packets that were dis-
carded due to a problem during decryption, such as mismatched WEP Keys. Bad Frame Checksum: This statistic displays the number of received packets that failed the CRC (Cyclic Redundancy Check) of the Frame Check Sequence (FCS). Last Frames RSSI: This statistic reports the RSSI (Received Signal Strength) for the last packet received by the PCI Card. RSSI is reported in decibels (dB) and typically ranges from 0 to 75. In general, an RSSI less than 15 indicates a weak signal and an RSSI greater than 30 indicates a strong signal. Duplicate Frames: This statistic displays the number of duplicate packets received by the PCI Card. When the PCI Card successfully receives a packet, it sends an acknowledgment (ACK) to the transmitting node. If the ACK does not reach the transmitting node within a specified period of time after it sent the packet (due to interference or some other type of delay), it will resend the packet to the recipient. In this case, the PCI Card then receives the packet a second time, records that it received a duplicate packet, and sends an ACK again. Harmony Utility 34 Link Quality When the PCI Card is in Infrastructure mode, click the Link Quality tab to view the list of Access Points within range of the PCI Card, as shown in the following example. You can perform a link quality test with any of the detected Access Points by clicking the Transmission Success Rate button. The Access Point screen reports the following information for each Access Point detected by the PCI Card:
AP Address: This field reports the physical (or MAC) address of the detected Access Point. SSID: This field reports the detected Access Points SSID or Service Set Identifier. See SSID on page 18 for more information. Channel: This field displays the Channel used by the detected Access Point. See Channel on page 20 for more information. Signal Strength: This field displays the strength of the radio signal received by the detected Access Point. Harmony Utility 35 Packet Transmission Success Rate When the PCI Card is configured for Infrastructure mode, select one of the detected Access Points in the Access Points screen and click Transmission Success Rate to determine the link quality between the PCI Card and the selected device. The PCI Card sends a series of packets to the selected Access Point and monitors the number of replies it receives. This information is converted to a percentage and plotted on the Packet Transmission Success Rate graph, as shown in the example below.

Troubleshooting 38 Common Installation Problems Chapter 2 describes how to install the Harmony 802.11a PCI Card in a computer running Windows 98 Second Edition (SE), Windows Millennium Edition (ME), and Windows 2000. This section provides some suggestions to resolve many of the common installation problems with the Harmony 802.11a PCI Card. PCI Card Not Listed in Device Manager Follow these steps if you have installed the 802.11a PCI Card but it doesnt appear as a network adapter in the Device Manager:
1. Open the Device Manager (located within the Control Panels System icon). Check the Other Devices category for a PCI Ethernet Controller or Ethernet 2. Controller entry. 3. 4. 5. 6. If the entry appears in the Other Devices category, highlight it and click Remove. Close the Device Manager. Restart the computer. Follow the installation instructions in Chapter 2 to install the Harmony driver and utility. 802.11a PCI Card Not Installed Properly If the Harmony Device Setup program or Windows Networking reports that the Harmony 802.11a PCI Card has not been properly installed or configured after you have completed the Harmony Installation program, open the Device Manager and locate the Harmony 802.11a PCI Cards entry in the Network adapters category. If a yellow exclamation point (!) appears next to the Harmony 802.11a PCI Cards Device Manager entry, then the card is not working properly. This is due either to an error during installation or to a system conflict. Follow these steps:
1. Uninstall the Harmony 802.11a PCI Card as described in Uninstalling the 802.11a PCI Card on page 41. Reinstall the Harmony 802.11a PCI Card following the installation instructions in Chapter 2. If the cards Device Manager entry still has an exclamation point (!) after you have reinstalled the card, highlight the entry and click Properties. 2. 3. 4. Click the Resources tab. Troubleshooting 39 5. Determine if the Harmony 802.11a PCI Card has been assigned an Interrupt Request or if it is having a resource conflict with another device that is already using the Interrupt Request (IRQ), I/O Base Address, or Memory Range for which the Harmony 802.11a PCI Card is configured. 6. If the PCI Card has not been assigned an IRQ, check the PCI configuration settings within the BIOS Setup screen to assign the 802.11a PCI Card available resources. A computers BIOS (Basic Input/Output System) automatically assigns resources to PCI cards during boot-up. The resources assigned to a PCI Card cannot be changed within Windows, only within the BIOS. 7. If problems persist, contact the PCs manufacturer to determine if an updated BIOS version is available that provides improved support for PCI devices. Troubleshooting 40 Configuring Networking Clients and Protocols The Harmony 802.11a PCI Card will bind to any existing networking components, such as Client for Microsoft Networks and the Internet Protocol (TCP/IP).

Troubleshooting 42 Range Every environment is unique with different obstacles, barriers, materials, etc., and, therefore, it is difficult to determine the exact range that will be achieved without testing. Radio signals may reflect off of some obstacles or be absorbed by others depending on their construction. The IEEE 802.11a specification supports eight data rates: 54 Mbps, 48 Mbps, 36 Mbps, 24 Mbps, 18 Mbps, 12 Mbps, 9 Mbps, and 6 Mbps. Harmonys 2X mode supports eight data rates: 108 Mbps, 96 Mbps, 72 Mbps, 48 Mbps, 36 Mbps, 24 Mbps, 18 Mbps, and 12 Mbps. Operation at 6 Mbps or 12 Mbps provides greater range than operation at 54 Mbps or 108 Mbps. By default, the Harmony 802.11a PCI Card will automatically adjust the data rate to maintain a usable radio connection. Therefore, a client that is close to an Access Point may operate at 54 Mbps while a client that is on the fringe of coverage may operate at 6 Mbps. Proper antenna placement can help improve range. Try to keep the PCI Cards integral antennas free of obstructions (particularly metal objects) and do not place a sheet of metal (like a filing cabinet) between 802.11a devices. Also, Proxim recommends that you use the Harmony Utility to evaluate the signal strength and link quality between 802.11a devices. Troubleshooting 43 Common Technical Support Questions This section discusses some of the most common problems using the Harmony 802.11a PCI Card and offers possible solutions Symptom/Question Possible Solution/Answer My office has an existing 802.11b network. Is the Harmony 802.11a PCI Card compatible?
No. 802.11a devices are not compatible with 802.11b devices. I want to install a Harmony 802.11a network in my office that has an existing 802.11b network. Will the 802.11a network interfere with the 802.11b network?
No. 802.11a and 802.11b devices will not interfere with each other since they operate at different frequencies. 802.11a devices operate in the 5 GHz band, and 802.11b devices operate in the 2.4 GHz band. Is the Harmony 802.11a PCI Card compatible with 802.11a products from other vendors?
In throughput tests, the 802.11a PCI Card doesnt seem to transfer data as quickly as Id expect. How do I determine where to install 802.11a Access Point to ensure that users can access the wireless network from anywhere in my facility?
Yes, the Harmony 802.11a PCI Card is interoperable with 802.11a-compliant products from other vendors. However, if you use 2X mode to achieve data rates up to 108 Mbps, the Harmony 802.11a PCI Card is only compatible with other 802.11a products from Proxim. Data rate is the raw signaling rate of a networking device; it does not equal data throughput. Actual data throughput is always less than the data rate since some of the available bandwidth is used to send control messages and regulate activity over the wireless medium. Also, throughput will depend on several factors such as network overhead, the file transfer program in use, the computers operating system, and the computers processor speed. Proxim recommends that you perform a site survey following the procedure outlined in Proxims Harmony Technical Training class. If you would like to learn more about the site survey procedure, you should consider signing up for a Proxim class in your area. Refer to http://www.proxim.com/ for more information.
