Regulation 21 Emission requirements for the frequency band 7.75 GHz to 7.9 GHzI1
United Kingdom
The requirements referred to in regulation 18 (j) are that the emissions have—
(i)
a maximum mean power spectral density—
(aa)
no greater than -41.3 dBm/MHz;
(bb)
no greater than -44.3 dBm/MHz –20*log10(10[km]/x[km])(dBm/MHz) (where x is the aircraft height above ground in kilometres) provided that the aircraft that the ultra-wideband equipment is onboard is higher than 1000 meters above ground level; or
(cc)
no greater than -64.3 dBm/MHz provided that the aircraft that the ultra-wideband equipment is onboard is at or lower than 1000 meters above ground level but not on ground level; and
(ii)
have a peak power no greater than 0.0 dBm or the equivalent transmission level.
