„
Spectrum Width : The available options for the channel bandwidth are:
»
20 MHz
»
20/40 MHz, allows both 20 and 40 MHz bands to be used (depending on the connected device).
„
Channel : Select a specific channel (the Auto option for selecting the channel with the least
interference is a future feature).
„
Wireless Mode: Defines the method of optimizing various wireless parameters:
»
Capacity mode provides maximum capacity to the maximum number of users. For a 2.4 GHz
radio you may select whether to support also low rate IEEE 802.11b clients ( Capacity 11bgn ) or
not ( Capacity 11gn ).
»
Coverage mode enables achieving maximum coverage (range) with some degradation in the
overall system capacity. Coverage mode can be useful in cases of low noise level (below -80dBm)
and low total Rx activity (when valid Rx activity plus interference is below 30%) as shown on the
Radio Status page. For a 2.4 GHz radio you may select whether to support also low rate IEEE
802.11b clients ( Coverage 11bgn ) or not ( Coverage 11gn ).
»
High Density mode provides optimization for serving a maximum number of clients in a
crowded area located at a relatively short distance from the base station. High Density mode
provides an optimal solution for environments where multiple base stations are use to effectively
serve a very large number of users in highly crowded areas such as sport stadiums, music arenas
and exhibition halls.
„
Transmit Power : The total transmit power at the antennas ports. Select a specific value or Max. The
maximum allowed value depends on applicable regulatory limitations and, in certain cases, the
operating channel.

„
Distance : The maximum distance (in Km) of any station from the AP. This parameter affects the value
of the ACK timeout to be used by the communication protocol and it should be set to a value that is
slightly higher than the physical distance between the AP and the farthest station.
3.5.2.2.2 Interface Configuration
The Interface Configuration section enables configuring various operational parameters for the wireless
network.
