Wireless Coverage

As a starting point for planning your network, you can assume that when operating at high power,
the AP's radio provides a wireless networking area (also called a wireless cell) of up to 300 feet (100
meters) in diameter. Before creating a permanent installation however, you should always perform a
site survey to determine the optimal settings and location for the AP.
The following sections provide information on wireless coverage. A tool that can help simplify
planning a secure wireless network is the Alvarion RF Planner. For more information, see the RF
Planner Admin Guide.
NOTE
Supported wireless modes, operating channels, and power output are determined by the
regulations of the country in which the AP is operating, and are controlled by the country setting on
the AP. For more information, see
6.1.1

Wireless Mode

Supported wireless modes may include the following:
802.11b: Up to 11 Mbps in the 2.4 GHz frequency band.
802.11g: Up to 54 Mbps in the 2.4 GHz frequency band.
802.11 b + g: Up to 11 Mbps and 54 Mbps in the 2.4 GHz frequency band.

Factors Limiting Wireless Coverage

Wireless coverage is affected by the factors discussed in this section.
6.1.2.1 Radio Power
More radio power means better signal quality and the ability to create bigger wireless cells.
However, cell size should generally not exceed the range of transmission supported by wireless
users. If it does, users will be able to receive signals from the AP but will not be able to reply,
rendering the connection useless.
Further, when more than one AP operates in an area, you must adjust wireless cell size to reduce
interference between APs. An automatic power control feature is available to address this challenge.
