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

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

Guidelines On The Use Of Short-Range Devices (SRDs) In Botswana released
on February 2022 [1]. The pages 20-21 describe:

* 2400 - 2483.5 MHz
  - 100 mW e.i.r.p.
  - EN 300 328
* 5150 - 5350 MHz
  - 200 mW mean e.i.r.p
  - EN 301 893
    * DFS: 5250 - 5350 MHz
    * for devices without TPC, the limit is lowered 3 dBm
      (reduce 5250 - 5350 MHz to 20 dBm)
* 5470 - 5725 MHz
  - 250 mW e.i.r.p
  - EN 301 893
    * DFS: 5470 - 5725 MHz
    * for devices without TPC, the limit is lowered 3 dBm
      - Not required for devices that operate at a maximum mean e.i.r.p. of
        27 dBm when operating in 5470 MHz to 5725 MHz
        (keep 250 mW for 5470 MHz to 5725 MHz)
* 5725 - 5875 MHz
  - BFWA is limited to 5725 - 5850 MHz
  - PTP/PTMP: max mean e.i.r.p = 4 W
  - Mesh/AP-MP: max mean e.i.r.p = 2 W
  - EN 302 502
    * DFS: 5725 - 5850 MHz
    * 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
