The range of the Wireless signal is related to the Transmit Rate of the
Wireless communication. Communications at lower Transmit range may
travel longer distances.
The range values listed in the table above are typical distances as
measured at the TOSHIBA Wireless LAN laboratories. These values
provide rule-of-thumb guides. They may vary according to the actual radio
conditions at the location where the Wireless LAN product is installed.
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 affected by obstacles in the signal path of the radio that
may either absorb or reflect the radio signal.
The above table lists the typical ranges when used indoors in office
environments such as the following:
In Open Office environments, where antennas can see each other,
i.e. there are no physical obstructions between them.
In Semi-open Office environments, where work space is divided by
shoulder-height, hollow wall elements; antennas are at desktop level.
In Closed Office environments, work space is separated by floor-to-
ceiling solid walls.
