802.11B Wireless Communication Ranges - Avaya AP-3 User Manual

Specifications
values provide a rule of thumb and may vary according to the actual radio conditions at the
location where the product is used.
The range of your wireless devices can be affected when the antennas are placed near metal
surfaces and solid high-density materials. Range is also impacted due to "obstacles" in the
signal path of the radio that may either absorb or reflect the radio signal.
In Open Office environments, antennas can "see" each other (no physical obstructions between
them). In Semi-open Office environments, work space is divided by shoulder-height, hollow wall
elements; antennas are at desktop level. In a Closed Office environment, solid walls and other
obstructions may affect signal strength.
The following tables show typical range values for various environments for FCC-certified
products (range may differ for products certified in other regulatory domains):
