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 2.4 GHz and 5 GHz 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
