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 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.
■
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.
