Communications of Authority of Kenya issued GUIDELINES ON THE USE OF
RADIOFREQUENCY SPECTRUM BY SHORT RANGE DEVICES on JUNE 2022 [1].
The section 5.8. covers frequency bands and technical parameters for
non-specific short range applications and wireless access systems.

 - 2400-2483.5 MHz: 2W e.i.r.p.
 - 5150-5350 MHz: 200mW; max e.i.r.p. density of 10mW/MHz
                  (ETSI [2]: 200mW (23dBm) -6 dBm to be 17 dBm;
                             5250-5350 DFS)
 - 5470-5725 MHz: 250mW; Max mean e.i.r.p. of 1W &
		  Max mean e.i.r.p. density of 50mW /MHz
                  (ETSI [2]: 1W (30dBm) -6 dBm to be 24 dBm)
 - 5725-5875 MHz: Mean e.i.r.p. spectral density of 23 dBm/MHz
                  Mean e.i.r.p. of 2W in any 10 MHz band
                  (ETSI [2]: 4W (36dBm) -6 dBm to be 30 dBm with TPC)
                  (ETSI [3]: The FWA device shall have the capability to
                   reduce the operating mean EIRP level to a level not
                   exceeding 24 dBm for ChS = 20 MHz and 21 dBm for
                   ChS = 10 MHz. 24 dBm is adopted)
 - 5925-6425 MHz:
   * LPI: 23 dBm (200 mW)
	  Mean e.i.r.p. density for in-band emissions 10 dBm/MHz
	  Indoor only
   * VLP: 14 dBm (25 mW)
	  Mean e.i.r.p. density for in-band emissions 1 dBm/MHz
	  Indoor and outdoor use

Reference ETSI EN 301 893 [2], for the 5 GHz and 5.8 GHz ranges, TPC is
required, being able to reduce TX power by up to 6 dB. ETSI EN 302 502 [3]
for TPC of 5.8 GHz. (Add this rule followed by [1] with annotation "ETSI:")

v3:
  - DFS-ETSI
  - split frequency 5250 - 5350 as an individual range for DFS
  - correct 5470 - 5725 to 24 dBm by e.i.r.p values.
  - correct 5725 - 5875 to 24 dBm by mean e.i.r.p. and ETSI EN 302 502, and
    more documentation.
v2:
  - align freq range of reference
  - use power unit as reference
  - -6dBm for 5 GHz and 5.8 GHz ranges
