Utility Regulation and Competition Office, Cayman Islands, released
Operating Parameters for Wireless Data Transmission (including WiFi)
Services On 18th November 2024 [1].

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.

v2:
  - extend "5470 - 5725" to "5470 - 5730" (+5MHz)
  - drop AUTO-BW from "5470 - 5725" and "5725 - 5875"
