Chapter 3 Radio Configuration and Basic Settings

Radio Configuration

Figure 3-8 AP Radio Restrict Searched Channels Page for the Internal Radio

The page lists all the channels in the access point’s regulatory domain. Click the Search check boxes beside the channels to include channels in the scan for less-congested channels. All the channels are included in the scan by default.

Receive Antenna and Transmit Antenna

Pull-down menus for the receive and transmit antennas offer three options:

•Diversity—This default setting tells the access point to use the antenna that receives the best signal. If your access point has two fixed (non-removable) antennas, you should use this setting for both receive and transmit.

•Right—If your access point has removable antennas and you install a high-gain antenna on the access point’s right connector, you should use this setting for both receive and transmit. When you look at the access point’s back panel, the right antenna is on the right.

•Left—If your access point has removable antennas and you install a high-gain antenna on the access point’s left connector, you should use this setting for both receive and transmit. When you look at the access point’s back panel, the left antenna is on the left.

Note The access point receives and transmits using one antenna at a time, so you cannot increase range by installing high-gain antennas on both connectors and pointing one north and one south. When the access point used the north-pointing antenna, it would ignore client devices to the south.

Entering Advanced Configuration Information

Use the AP Radio Advanced pages to assign special configuration settings for the access point radios. The internal radio and the radio module both have an AP Radio Advanced page. Both pages contain the same settings, but the Advanced page for the external radio module does not contain the Radio Modulation and Radio Preamble settings. Figure 3-9shows the AP Radio Advanced page for the internal radio.
