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.
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.
Supported frequency sub-bands
Subject to the radio regulations that apply in your country/region, your Wireless
LAN card may support a different set of 5 GHz/2.4 GHz channels.
Consult your Authorized Wireless LAN or TOSHIBA Sales office for informa-
tion about the radio regulations that apply in your country/region.
