(ii) have a maximum peak power—
(aa) no greater than -40.0 dBm or the equivalent transmission level; or
(bb) no greater than 0.0 dBm or the equivalent transmission level provided that one of the two techniques referred to in regulation 7 is used to mitigate interference to other users of the electromagnetic spectrum;
(f) in the frequency band 3.8 GHz to 4.8 GHz when measured in any direction—
(i) have a maximum mean power spectral density—
(aa) no greater than -70.0 dBm/MHz; or

(ii) a maximum peak power no greater than 0.0 dBm or the equivalent transmission level;
(i) in the frequency band 8.5 GHz to 9 GHz when measured in any direction have—
(i) a maximum mean power spectral density—
(aa) no greater than -65.0 dBm/MHz; or
(bb) no greater than -41.3 dBm/MHz provided that the technique referred to in regulation 7(b) is used to mitigate interference to other users of the electromagnetic spectrum; and
