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 Altitude 802.11n 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:
Request New Channel - Click the wireless channel you want the Altitude 802.11n AP to use to
communicate with wireless devices.
Click Auto to request the ACS to search for a new channel for the Altitude AP, using a channel
selection algorithm. This forces the Altitude 802.11n AP to go through the auto-channel selection
process again.
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."
Guard Interval - Click a guard interval, Long or Short, when a 40MHz channel is used. It is
recommended to use a short guard interval in small rooms (for example, a small office space) and
a long guard interval in large rooms (for example, a conference hall).
Max Tx Power - Click the maximum Tx power level that the range of transmit power can be
adjusted: 0 to 24 dBm. It is recommended to use 24 dBm to not limit the potential Tx power level
range that can be used.
Min Tx Power - If ATPC is enabled, click the minimum Tx power level that the range of transmit
power can be adjusted. It is recommended to use the lowest value available to not limit the
potential Tx power level range that can be used.
NOTE
The Minimum Tx Power level is subject to the regulatory compliance requirement for the selected country.
Auto Tx Power Ctrl Adjust - 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 dB 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 the
recommended values your RF plan has provided. Use the Auto Tx Power Ctrl Adjust value to
achieve the recommended values.
Current Channel - This field is view only. It displays the actual channel the ACS has assigned to
the Altitude 802.11n AP radio. The Current Channel value and the Request New Channel value
may be different because the ACS automatically assigns the best available channel to the Altitude
802.11n AP, ensuring that a Altitude 802.11n AP's radio is always operating on the best available
channel.
Last Requested Channel - This field displays the last wireless channel that you had selected for
the Altitude 802.11n AP to communicate with the wireless devices.
Auto Tx Power Ctrl (ATPC) - Select to enable ATPC. 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.
