United Republic of Tanzania, Tanzania Communications Regulatory Authority
released Minimum Technical Specifications for Short Range Devices (SRDs)
on 2024 [1].

 * 2400-2483.5 MHz
   - 100 mW e.i.r.p.
 * 5150-5350 MHz
   - 200 mW mean e.i.r.p.
     * The maximum mean e.i.r.p. density shall be limited to 10 mW/MHz
       in any 1 MHz band.
   - EN 301 893
     * without TPC: 20 dBm when operating in 5250-5350 MHz
       (20 dBm is adopted for 5250-5350 MHz)
     * DFS: 5250-5350 MHz
   - Restricted to indoor use.
 * 5470-5725 MHz
   - 250 mW e.i.r.p
     * The maximum mean e.i.r.p. density shall be limited to 50 mW/MHz
       in any 1 MHz band
   - EN 301 893
     * DFS: 5470-5725 MHz
   - Indoor as well as outdoor use allowed.
 * 5725-5850 MHz
   - 1W
   - EN 302 502
     * DFS: 5850 - 5875 MHz
     * FWA device shall have the capability to reduce the operating
       mean EIRP level to a level not exceeding 24 dBm for ChS = 20 MHz
       (24 dBm is adopted)
 * 5945-6425 MHz
   - 23 dBm for LPI usage
     (should be indoor naturally)
   - 14 dBm for VLP usage

v3:
  - remove NO-OUTDOOR from 5470-5725 MHz, since "Indoor as well as outdoor
    use allowed."
v2:
  - 20 dBm when operating in 5250-5350 MHz for devices without TPC
