¹ Duty cycle of maximum 5% per second per transmitter on time ($Ton$). ² Duty cycle limited to 1.5% per minute per transmitter on time ($Ton$) or an alternative mitigation technique should be used to achieve the same protection. ³ The maximum mean e.i.r.p. spectral density in the band 4.2 GHz to 4.4 GHz for emissions that appear 30° or greater above the horizontal plane should be less than −47.3 dBm/MHz, see clause 4.6.1.4 ECC/REC(11)09.
