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 controller to systematically
assign channels. Default is Random.
Power (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 Point and Clients. Decrease the power
level according to the proximity of other Access Points. Overlapping RF coverage may cause lost
packets and difficulty for roaming devices trying to engage a Access Point. After setting a
power level, channel and placement the RF output power for the Access Point 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 Point is
displayed below in mW.

users. If needed, additional radio settings can be modified for the following properties:
Antenna Diversity Use the drop-down menu to configure the Antenna Diversity settings for Access
Points using external antennas. Options include:
•
•
•
Antenna Diversity should only be enabled if the Access Point has two matching
external antennas. Default value is Full Diversity.
Maximum Clients
Sets the maximum number of Clients that can associate to a radio. The maximum
number of stations that can associate to a radio are 256.
Adoption Preference ID The Adoption Preference ID defines the preference ID of the controller.The value
can be set between 1 and 65535. To make the radios preferred, the Access Point
preference ID should be same as adoption preference ID.
The adoption preference id is used for RP load-balancing. A controller will
preferentially adopt Access Points which have the same adoption-preference-id as
the controller itself.
Short Preambles only If using an 802.11 bg radio, select this checkbox for the radio to transmit using a
short preamble. Short preambles improve throughput. However, some devices
(SpectraLink phones) require long preambles. This checkbox does not display if
using an 802.11a radio.

Full Diversity - Utilizes both antennas to provide antenna diversity.
Primary Only - Enables only the primary antenna.
Secondary Only - Enables only the secondary antenna.
