Radio Characteristics
Radio Characteristics of Wireless LAN module 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.
Radio Frequency
Band 5GHz (5150-5850 MHz) (Revision a
and n)
Band 2.4GHz (2400-2483.5 MHz) (Revision
b/g and n)
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.
