WebSignal strength in telecommunications. In telecommunications, particularly in radio frequency, signal strength refers to the transmitter power output as received by a reference antenna at a distance from the transmitting antenna. High-powered transmissions, such as those used in broadcasting, are expressed in dB-millivolts per metre (dBmV/m). WebApr 8, 2024 · Excellent signal strength = -64 dBm to -50 dBm; See the cell signal strength chart below for a great comparison: The typical range of measure for cell signal strength is between -110 dBm and -30 dBm. Being a logarithmic unit of measure, each 3-dB increase is actually doubling the power.
