EIRP adjusts the total radiated power for the antenna gain. So if you're transmitting 1 W and your antenna has a gain of 30 dBi (1000x), that's equivalent (from the perspective of whatever it's pointed at) to an isotropic antenna (no gain) emitting 1000 W at the same distance. It should be obvious that EIRP is what matters for interference and human safety, hence why the FCC regulates EIRP instead of power output. |
