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.

Sorry for the late reply.
Can you follow the TW example and extend this band by 5MHz and also
drop the AUTO-BW?
> + (5725 - 5875 @ 80), (1000 mW), AUTO-BW
AUTO-BW for this band doesn't make sense. While the frequency ranges do
align up, the channel assignments don't, so there's no way one can combine
this and the previous band for a 160 MHz channel.
Thanks
