Toshiba Wireless LAN mini-PCI Card – Getting started
The range of the wireless signal is related to the Transmit Rate of the wireless
communication. Communications at lower Transmit range may travel larger distances.
NOTE:
The range values listed in Table A-4 are typical distance as measured at the Toshiba
Wireless LAN laboratories. These values may provide a rule of thumb and may vary
according to the actual radio conditions at the location where the Wireless LAN product
will be installed.
n The range of your wireless devices can be affected when the antennas are placed
near metal surfaces and solid high-density materials.
n Range is also impacted due to “obstacles” in the signal path of the radio that may
either absorb or reflect the radio signal.
Table A-4 lists the typical ranges when used indoors in “office environments” that can be
described as follows:
n In Open Office environments, antennas can “see” each other, i.e. there are no
physical obstructions between them.
n In Semi-open Office environments, work space is divided by shoulder-height, hollow
wall elements; antennas are at desktop level.
n In Closed Office environments, work space is separated by floor-to-ceiling brick
walls.
