EIRP (Effective Isotropic Radiated Power) is the measured radiated power of an antenna in a specific direction. It is also called Equivalent Isotropic Radiated Power. It is the output power when a signal is concentrated into a smaller area by the Antenna. EIRP = 10 log(Power in watts) + Antenna gain.
What is EIRP formula?
EIRP = P_Tx - L_Tx + G_Tx For example, a transmitting station has 1000 W (or 30 dBW) as its transmitter output and uses an antenna with a gain of 10 dBi. The cable to the antenna introduces a 3 dB loss to the signal. The station EIRP would be: 30 dBW - 3 + 10 = 37 dBW (5011 W).
Why is EIRP important?
EIRP is vital to determine transmitter power and beam verification of a 5G base station. The reason is that active antenna systems operate much differently than the isotropic antennas used for many years in traditional cellular applications.
What is EIRP measured in?
remote receiving antenna is the effective isotropic radiated power (EIRP), measured in watts per metre squared. To achieve high EIRP the antenna dimensions should be several times larger than the largest transmitted wavelength.
