Both FCC and EU reference are permitted. Adopt FCC reference. * 2400 - 2483.5 MHz - Part 15.247 * 1 Watt For systems using digital modulation in the 902 - 928 MHz, 2400-2483.5 MHz, and 5725 - 5850 MHz bands: 1 Watt. * 5150 - 5350 MHz - Part 15.407 * 250 mW For client devices in the 5.15-5.25 GHz band, the maximum conducted output power over the frequency band of operation shall not exceed 250 mW provided the maximum antenna gain does not exceed 6 dBi. In addition, the maximum power spectral density shall not exceed 11 dBm in any 1 megahertz band. For the 5.25-5.35 GHz and 5.47-5.725 GHz bands, the maximum conducted output power over the frequency bands of operation shall not exceed the lesser of 250 mW or 11 dBm + 10 log B, where B is the 26 dB emission bandwidth in megahertz. In addition, the maximum power spectral density shall not exceed 11 dBm in any 1 megahertz band. * DFS: 5.25-5.35 GHz * 5470 - 5725 MHz - Part 15.407 * 250 mW For the 5.25-5.35 GHz and 5.47-5.725 GHz bands, the maximum conducted output power over the frequency bands of operation shall not exceed the lesser of 250 mW or 11 dBm + 10 log B, where B is the 26 dB emission bandwidth in megahertz. In addition, the maximum power spectral density shall not exceed 11 dBm in any 1 megahertz band. * DFS: 5.47-5.725 GHz * 5725 - 5875 - Part 15.407 * 1 W For the band 5.725-5.85 GHz, the maximum conducted output power over the frequency band of operation shall not exceed 1 W. * 5925 - 6425 MHz - Part 15.407 (but no description; reference [2]) * -1 / MHz (12 dBm is adopted) Accordingly, the Commission concludes that the appropriate maximum power spectral density for low power indoor client devices in this band is 6 dB below the limit for access points (or -1 dBm/MHz based on the adopted PSD limit). * NO-OUTDOOR * 57 - 71 GHz - Part 15.255 (but no power value; reference [3]) * 40 dBm The average power of any emission shall not exceed 40 dBm and the peak power of any emission shall not exceed 43 dBm.
