CHAPTER 4: SYSTEM CONFIGURATION NOTE: The Antenna ID must be selected in conjunction with the Output Antenna to configure proper use of any of the antenna options. Output Antenna - Selects the use of both fixed antennas operating in diversity mode or a single antenna. (Default: Diversity) „ Both: The radio uses both antennas in a diversity system. Select this method when the Antenna ID is set to "3Com Integrated Antenna" to use the access point's integrated antennas. „ Right: The radio only uses the antenna on the right side (the side closest to the access point LEDs). Select this method when using an optional external antenna that is connected to the right antenna connector. „ Left: The radio only uses the antenna on the left side (the side farthest from the access point LEDs). Select this method when using an optional external antenna that is connected to the left antenna connector. Transmit Power - Adjusts the power of the radio signals transmitted from the access point. The higher the transmission power, the farther the transmission range. Power selection is not just a trade off between coverage area and maximum supported clients. You also have to ensure that high-power signals do not interfere with the operation of other radio devices in the service area. (Options: 100%, 50%, 25%, 12%, minimum; Default: 100%) NOTE: When operating the access point using 5 GHz channels in a European Community country, the end user and installer are obligated to operate the device in accordance with European regulatory requirements for Transmit Power Control (TPC). Maximum Transmit Data Rate - The maximum data rate at which the access point transmits unicast packets on the wireless interface. The maximum transmission distance is affected by the data rate. The lower the data rate, the longer the transmission distance. (Options: 6, 9, 12, 18, 24, 36, 48, and 54 for 802.11a; 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, and 54 for 802.11b/g; Default: 54 Mbps) Maximum Multicast Data Rate - The maximum data rate at which the access point transmits multicast and broadcast packets on the wireless interface. (Options: 24, 12, 6 Mbps; Default: 6 Mbps for 802.11a; 1, 2, 5.5, 11, Default 5.5 Mbps for 802.11b/g) Beacon Interval - The rate at which beacon signals are transmitted from the access point. The beacon signals allow wireless clients to maintain contact with the access point. They may also carry power-management information. (Range: 20-1000 TUs; Default: 100 TUs) 4-40

Output Antenna

– Selects the use of both fixed antennas operating in diversity

Both: The radio uses both antennas in a diversity system. Select this method

when the Antenna ID is set to “3Com Integrated Antenna” to use the access

Right: The radio only uses the antenna on the right side (the side closest to the

access point LEDs). Select this method when using an optional external antenna

that is connected to the right antenna connector.

Left: The radio only uses the antenna on the left side (the side farthest from the

access point LEDs). Select this method when using an optional external antenna

that is connected to the left antenna connector.

– Adjusts the power of the radio signals transmitted from the

access point. The higher the transmission power, the farther the transmission

range. Power selection is not just a trade off between coverage area and

maximum supported clients. You also have to ensure that high-power signals do

not interfere with the operation of other radio devices in the service area.

(Options: 100%, 50%, 25%, 12%, minimum; Default: 100%)

2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, and 54 for 802.11b/g; Default: 54 Mbps)

Maximum Multicast Data Rate

– The maximum data rate at which the access

(Options: 24, 12, 6 Mbps; Default: 6 Mbps for 802.11a; 1, 2, 5.5, 11, Default

5.5 Mbps for 802.11b/g)

Beacon Interval

– The rate at which beacon signals are transmitted from the

access point. The beacon signals allow wireless clients to maintain contact with

the access point. They may also carry power-management information.

(Range: 20-1000 TUs; Default: 100 TUs)
