Toshiba Wireless LAN mini-PCI Card – Getting startedThe range of the wireless signal is related to the Transmit Rate of the wirelesscommunication. 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 ToshibaWireless LAN laboratories. These values may provide a rule of thumb and may varyaccording to the actual radio conditions at the location where the Wireless LAN productwill be installed.! The range of your wireless devices can be affected when the antennas are placednear metal surfaces and solid high-density materials.! Range is also impacted due to “obstacles” in the signal path of the radio that mayeither absorb or reflect the radio signal.Table A-4 lists the typical ranges when used indoors in “office environments” that can bedescribed as follows:! In Open Office environments, antennas can “see” each other, i.e. there are nophysical obstructions between them.! In Semi-open Office environments, work space is divided by shoulder-height, hollowwall elements; antennas are at desktop level.! In Closed Office environments, work space is separated by floor-to-ceiling brickwalls.
