Wireless Communication Range

The range of the wireless signal is related to the composition of objects in the radio wave path and the transmit rate of the wireless
communication. Communications at a lower transmit range may travel longer distances. The range values listed in the Communications
Range Chart are typical distances as calculated by Proxim’s development team for FCC-certified products. These 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,
workspace 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).
