7Transmit power / Power densityThe maximum e.i.r.p. of ESOMPs installed on aircraft operating within the airfield boundary including operations on the ground shall be limited to 58.4 dBW.
The maximum e.i.r.p. of land-based ESOMPs operating within the airfield boundary shall be limited to 52.4 dBW.
The maximum e.i.r.p. of ESOMPs not covered in a) and b), outside the airfield boundary or on vessels, shall be limited to 60 dBW.
The maximum e.i.r.p. of ESOMPs, as defined above, operating within TDMA networks shall be respected after taking into consideration the duty cycle (see section 3.3 and 3.4 of ECC Report 272).
Additional restrictions according to ECC/DEC/(13)01.
Power restrictions according to ECC Report 272.
8Channel access and occupation rulesAccording to ECC/DEC/(13)01.- Within the frequency bands 17.3-20.2 GHz and 27.5-30.0 GHz, ESOMPs shall operate only in the portions of these frequency bands identified for their use within the territory of operation.
- ESOMPs operating in international waters or international airspace (which may transmit within the range 27.5-30.0 GHz), shall ensure protection of fixed service systems in the CEPT.
- ESOMPs transmitting in the band 29.5-30.0 GHz shall comply with the requirements in Annex 1 of ECC/DEC/(13)01.
- ESOMPs transmitting in the band 27.5-29.5 GHz shall comply with the requirements in Annexes 1, 2 and 3 of ECC/DEC/(13)01.
9Authorisation regimeSwitzerland: License required.
Liechtenstein: Individual assignment required.
Switzerland: The exemption from the individual licence requirement only applies subject to a valid license for the Swiss territory that includes the use of individual customer terminals.
Liechtenstein: The exemption from the individual licensing requirement only applies subject to a valid license for the Lichtenstein territory that includes the use of individual customer terminals.
ESOMPs receiving in the band 17.7-19.7 GHz shall not claim protection from interference from fixed stations operating in the same band and in conformity with their national regulations.
ESOMPs receiving in the band 17.3-17.7 GHz shall not claim protection from BSS feeder links operating in the same band and in conformity with their national regulations.
