The setting will affect the selection channel and power levels. Default is Indoor.
10.Select a channel for communications between the access port and MUs in the
The selection of a channel determines the available power levels. The range of legally approved
communication channels varies depending on the installation location and country. The selected channel
can be a specific channel, "Random," or "ACS." Random assigns each radio a random channel. ACS
(Automatic Channel Selection) allows the switch to systematically assign channels. Default is Random.
11.After first selecting a channel, select a power level in dBm for RF signal strength in the
(dBm) field.
The optimal power level for the specified channel is best determined by a site survey prior to installation.
Available settings are determined according to the selected channel. Set a higher power level to ensure
RF coverage in WLAN environments that have more electromagnetic interference or greater distances
between the access port and MUs. Decrease the power level according to the proximity of other access
ports. Overlapping RF coverage may cause lost packets and difficulty for roaming devices trying to
engage a access port. After setting a power level, channel and placement the RF output power for the
access port is displayed in mW. Default is 20 dBm (802.11bg), 17 dBm (802.11a)
NOTE: After setting a power level, channel and placement the RF output power for the
access port is displayed below in mW.
12.To configure optional rate settings, click the
rate setting information. Instructions on configuring rate settings are described in

Advanced Properties
Use the drop-down menu to configure the Antenna Diversity settings for access
ports using external antennas. Options include:
• Full Diversity: Utilizes both antennas to provide antenna diversity.
• Primary Only: Enables only the primary antenna.
• Secondary Only: Enables only the secondary antenna.
Antenna Diversity should only be enabled if the access port has two matching
external antennas. Default value is
Sets the maximum number of MUs that can associate to a radio. The maximum
number of stations that can associate to a radio are 64.
The Adoption Preference ID defines the preference ID of the switch.The value can
be set between 1 and 65535. To make the radios preferred, the access port
preference ID should be same as adoption preference ID.
The adoption preference id is used for RP load-balancing. A switch will
preferentially adopt access ports which have the same adoption-preference-id as
the switch itself.
