Configuring the Altitude AP
Use broadcast for disassociation - Select if you want the Altitude AP to use broadcast
disassociation when disconnecting all clients, instead of disassociating each client one by one.
This will affect the behavior of the AP under the following conditions:
If the Altitude AP is preparing to reboot or to enter one of the special modes (DRM initial
channel selection).
If a BSSID is deactivated or removed on the Altitude AP.
This option is enabled by default.
Country - Click the country of operation. This option is only available with some licenses.
9 In the Radio Settings section, do the following:
Radio mode - Click the radios you want to enable.
DTIM - 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 - For each radio, type the desired time, in milliseconds, between beacon
transmissions. The default value is 100 milliseconds.
RTS/CTS - For each radio, 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 - For each radio, 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.
RF Domain - For each radio, 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.
Channel - For each radio, click the wireless channel you want the Altitude APs to use to
communicate with wireless devices.
Click Auto to request the ACS to search for a new channel for the Altitude APs, using a channel
selection algorithm. This forces the APs to go through the auto-channel selection process again.
If DRM is enabled (DRM is enabled by default), it scans automatically for a channel, using a
channel selection algorithm.
Depending on the regulatory domain (based on country), some channels may be restricted. The
default value is based on North America. For more information, see
information."
Auto Tx Power Ctrl - For each radio, click to either enable or disable ATPC from the Auto Tx
Power Ctrl drop-down list. ATPC automatically adapts transmission power signals according to
the coverage provided by the Altitude APs. After a period of time, the system will stabilize itself
based on the RF coverage of your Altitude APs.
Max Tx Power - For each radio, click the appropriate Tx power level from the Max TX Power
drop-down list. The values in the Max TX Power drop-down is in dBm (dBm is an abbreviation
for the power ratio in decibel (dB) of the measured power referenced to one milliwatt).
Min Tx Power - For each radio, if ATPC is enabled, click the minimum Tx power level that the
range of transmit power can be adjusted: 0 to 18 dBm. It is recommended to use 0 dBm to not
limit the potential Tx power level range that can be used.
Auto Tx Power Ctrl Adjust - For each radio, if ATPC is enabled, click the Tx power level that can
be used to adjust the ATPC power levels that the system has assigned. It is recommended to use
0 dBm during your initial configuration. If you have an RF plan that recommended Tx power
levels for each Altitude AP, compare the actual Tx power levels your system has assigned against
