Wireless LAN

The range of the wireless signal is related to the transmit rate of the

wireless communication device. Communications at a lower transmission

rate 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 path of the

transmission that may either absorb or reflect the radio signal.

Supported Frequency Sub-bands

Subject to the radio regulations that apply in the countries/regions, your

Wireless LAN card may support a different set of 2.4 GHz channels.

Consult your Authorized Wireless LAN or TOSHIBA Sales office for

information about the radio regulations that apply in the countries/regions.
