R-F Frequency
Modulation Technique
The range of the wireless signal is related to the transmit rate of the wireless
communication. Communications at lower transmit range may travel larger dis-
tances.
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 affected by "obstacles" in the signal path of the radio signals
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 information
about the radio regulations that apply in your country/region.
