Wireless 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 measured at the development laboratories.
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. Ranges for outdoor antenna installations are related to type of outdoor antennas used, and length of antenna cables. 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 table shows typical range values for various environments.
