Correct answer: Transmit Power, Cable Loss, Antenna Gain.
Why this is the answer
EIRP (Effective Isotropic Radiated Power) quantifies the power radiated by an antenna in a specific direction, assuming an isotropic radiator. It's a crucial metric in wireless communication for regulatory compliance and link budget calculations. The formula for EIRP is: EIRP = Transmit Power (dBm) - Cable Loss (dB) + Antenna Gain (dBi). Transmit Power is the raw power output from the radio. Cable Loss accounts for signal degradation as it travels through the cable from the radio to the antenna. Antenna Gain represents the antenna's ability to focus RF energy in a particular direction. RSSI (Received Signal Strength Indicator) and SNR (Signal-to-Noise Ratio) are measurements of the received signal, not components of the transmitted power.
