[Ping-Ke Shih <pkshih@gmail.com>]

From: Ping-Ke Shih <pkshih@realtek.com>

COMMUNICATIONS REGULATORY AUTHORITY OF NAMIBIA released NOTICE IN TERMS OF
THE REGULATIONS REGARDING THE SUBMISSIONS OF INTERCONNECTION AGREEMENTS
AND TARIFFS on 3 April 2023 [1].

* 2400-2483.5 MHz
  100 mW e.i.r.p.

* 5150-5350 MHz
  200 mW mean e.i.r.p.
  Restricted to indoor use
  The maximum mean e.i.r.p. density shall be limited to 10 mW/MHz
  (ETSI [2]: 200mW (23dBm) -3 dBm to be 20 dBm; DFS 5250-5350)

* 5470-5725 MHz
  250 mW e.i.r.p.
  Indoor as well as outdoor use allowed.
  The maximum mean e.i.r.p. density shall be limited to 50 mW/MHz
  (ETSI [2]: 250mW (24dBm) -3 dBm to be 21 dBm; DFS)

* 5725-5875 MHz
  PTP/PTMP: max mean e.i.r.p = 4 W
  Mesh/AP-MP: max mean e.i.r.p = 2 W
  (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; DFS)

* 5925-6425 MHz
  - 23 dBm (200mW) mean e.i.r.p
    Restricted to indoor use only.
    Mean e.i.r.p density for in-band emissions = 10 dBm/MHz
  - 14 dBm (25) e.i.r.p mW
    Very Low Power (VLP) indoor outdoor use.
    Maximum mean e.i.r.p. for inband emissions = 1 dBm/MHz

* 57-66 GHz
  40 dBm (10W) mean e.i.r.p
  23 dBm/MHz e.i.r.p. density
  Indoor use only

The EN 301 893 [2] specifies reduced power limit of 23 and 27 dBm for
5150-5350 MHz and 5470-5725 MHz respectively for devices that don't
implement TPC. Also reduced TPC requires being able to reduce TX power by
up to 3 dB. The DFS applicable frequency range are 5250-5350 MHz and
5470-5725 MHz.

v2:
  - join to the same patchset
  - 5150-5350 and 5470-5725 only reduce 3dB due to TPC
  - 5725-5875 requires DFS
  - fix wording in commit message:
    * '5725-5 875 MHz' --> '5725-5875 MHz'
    * '10 dBM/MHz' --> '10 dBm/MHz'
    * 'Maximum meand e.i.r.p.' --> 'Maximum mean e.i.r.p' (drop extra 'd')
