Radio Characteristics

Radio Characteristics of Wireless LAN Cards may vary according to:
■
country/region where the product was purchased
■
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 and 5GHz band, local
radio regulations may impose a number of limitations to the use of
wireless communication equipment.
Refer to the flyer "Information to the User" for regulatory information that
may apply in your country/region.
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 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.
