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.

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.
