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 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. 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.
Refer to the sheet “Information to the User” for regulatory information that
may apply in your country/region.
