Radio Characteristics

Radio Characteristics of Wireless LAN Cards may vary according to:
Country/region where the product was purchased
n
n 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 sheet "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 device. Communications at a lower transmission rate may travel
larger distances.
n The range of your wireless devices can be affected when the antennas are
placed near metal surfaces and solid high-density materials.
n Range is also impacted due to "obstacles" in the path of the transmission that
may either absorb or reflect the radio signal.
