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.

Wireless LAN module may support a different set of 5 GHz/2.4 GHz
