RF system is responsible for the transmission and reception of wireless signals. RF Transmission: An RF signal is created by upshifting a low bandwidth (DC-like) signal to radio frequency by a radio transmitter. RF reception: An RF signal is picked up by the antenna and downshifted to a low bandwidth (DC-like) signal by a radio receiver.
