System Characteristics
Receiver Sensitivity
The minimum RF signal power level required at the input of a receiver for certain
performance (e.g. BER).
EIRP (Effective Isotropic Radiated Power)
The antenna transmitted power. Equal to the transmitted output power minus cable loss
plus the transmitting antenna gain.
