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.
