Wireless Sensor Networks

The part of the electromagnetic spectrum allocated by ITU for radio communications, ranging from 8.3KHz to 3 THz.

The relationship is given by λ = c/f, where λ is the wavelength, f is the frequency, and c is the speed of light.

UHF (300-3000MHz) for WLAN, GSM/GPRS; SHF (3-30GHz) for radio astronomy, microwaves, WLAN, satellites communications, and modern mobile telephony.
