For bridging Point to Point and Point to Multipoint you can go 1 Watt (30dBm) to the antenna and 4 Watt 36 (dBm) out of the antenna. The FCC regs don't address AP's that much. Not reason to amp an AP really. You can get the signal boost you need with aftermarket antennas, both omni and directional if that's what you want. Keep your coax runs and pigtails as short as you can to diminish signal loss and get like a 7-9 dBi omni to extend your cell coverage.
