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.
