Radio transmission power

Radio transmission power, often referred to as Effective Radiated Power (ERP) or Transmitter Power Output (TPO), is a measure of the strength of a radio signal transmitted from an antenna. It quantifies how much power is actually emitted into the environment to propagate a radio wave. 1. **Units of Measurement**: Transmission power is typically measured in watts (W) or decibels relative to a milliwatt (dBm).
