Signal strength, in telecommunications, is the magnitude of an electric field at a reference point, which is located at a significant distance from the transmitting antenna. This is expressed in terms of the signal power of the receiver or the voltage per length recieved by the reference antenna.
High-power transmissions used in broadcasting are expressed in dB-millivolts per meter (dBmV/m). In low-power systems, including mobile phones, the signal strength is expressed in dB-microvolts per meter (dBµV/m).
