Antenna Diversity 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.
•
MIMO: Multiple-Input and Multiple-Output. This field is only available with type 'n' radios.
Antenna Diversity should only be enabled if the Access Port 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 Clients that can
associate to a radio is 64.
Adoption Preference ID Displays the preference ID of the switch.The value can be set between 1 and 65535. To define the radios as
preferred, the Access Port preference ID should be the same as adoption preference ID.
The adoption preference ID is used for AP load-balancing. A switch will preferentially adopt APs, which have the
same adoption-preference-ID as the switch itself.

The channel for communication between the Access Port and its associated Clients can be
using the primary radio or the secondary radio of an AP. Accordingly the channel is called
Desired Channel (Pri) or Desired Channel (Sec) respectively.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.
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 Port and Clients. Decrease the power
level according to the proximity of other Access Ports. Overlapping RF coverage may cause lost
packets and problems for roaming devices trying to connect to an Access Port. After setting a
power level, channel, and placement the RF output power for the Access Port is displayed in
mW. The default is 20 dBm (802.11bg), 17 dBm (802.11a).
