Short-Range Wireless Networks
Short-range wireless networks , short SRWN ( dt. " Wireless networks for short range ), is the generic term of various wireless technologies with a physically very limited range of a few meters or even just centimeters to the SRWN wireless technologies include, for example.:
The range limitation is mainly achieved by reducing the transmission power . The greater free space attenuation at high transmission frequencies contributes to minimizing the range.
