Wireless LAN
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 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.
Refer to the sheet "Information to the User" for regulatory information that
may apply in your country/region.
