9 If applicable, click the 802.11a tab to modify the radio properties:
10 In the Base Settings section, do the following:
Radio Mode - Click one of the following radio options:
a - Click to enable the 802.11a radio.
off - Click to disable the 802.11a radio.
DTIM Period - Type the desired DTIM (Delivery Traffic Indication Message) period - the number
of beacon intervals between two DTIM beacons. To ensure the best client power savings, use a
large number. For example, 5. Use a small number to minimize broadcast and multicast delay.
The default value is 5.
Beacon Period - Type the desired time, in milliseconds, between beacon transmissions. The
default value is 100 milliseconds.
RTS/CTS Threshold - Type the packet size threshold, in bytes, above which the packet will be
preceded by an RTS/CTS (Request to Send/Clear to Send) handshake. The default value is 2346,
which means all packets are sent without RTS/CTS. Reduce this value only if necessary.
Frag. Threshold - Type the fragment size threshold, in bytes, above which the packets will be
fragmented by the AP prior to transmission. The default value is 2346, which means all packets
are sent unfragmented. Reduce this value only if necessary.
11 In the Basic Radio Settings section, do the following:
RF Domain - Type a string that uniquely identifies a group of APs that cooperate in managing RF
channels and transmission power levels. The maximum length of the string is 16 characters. The
RF Domain is used to identify a group of Altitude APs.
Current Channel - This field is view only. It displays the actual channel the ACS has assigned to
the Altitude AP radio. The Current Channel value and the Requested Channel value may be
different because the ACS automatically assigns the best available channel to the Altitude AP,
ensuring that an Altitude AP's radio is always operating on the best available channel.
