Radio Characteristics
Radio Characteristics of Wireless LAN Cards may vary according to:
Q
Country/region where the product was purchased
Q
Type of product
Wireless communication is often subject to local radio regulations.
Although Wireless LAN wireless networking products have been designed
for operation in the license-free 2.4GHz band, local radio regulations may
impose a number of limitations to the use of wireless communication
equipment.
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.
Q
The range of your wireless devices can be affected when the antennas
are placed near metal surfaces and solid high-density materials.
Q
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 the countries/regions, your
Wireless LAN card may support a different set of 2.4 GHz channels.
Consult your Authorized Wireless LAN or your dealer for information about
the radio regulations that apply in the countries/regions.
