"Using the 1 watt as our transmitter power translates to 0.000507 watt (0.507 milliwatts or 507 microwatts) at the receiving end. "
But it's even worse than this! The FCC does not allow you to transmit at the full 1 watt (30 dBm) if you focus the energy with more than 6 dB gain. If you want to use a phase array to get 21 dB antenna gain, you must drop your transmit power to 25 dBm or 0.316 watts. Every 3 dBi of antenna gain must be accompanied by 1 dBm decline in transmit power.
