CEPT position on WRC-12 AI’s 1.3, 1.4, 1.7, 1.12 and 1.25

1. Eric ALLAIX DGAC-DSNA CEPT position on WRC-12 AI’s 1.3, 1.4, 1.7, 1.12 and 1.25

2. CEPT preliminary position on AI 1.3(1/4) • Spectrum demand of 34 MHz for terrestrial and 56 MHz for satellite spectrum as determined by Report ITU-R M.2177 • Spectrum use for the purpose of control and non-payload communication must be in accordance with international aeronautical standards

3. CEPT preliminary position on AI 1.3(2/4) Terrestrial component –terrestrial radiocommunication links between the UACS and an UA have to be considered as an application of the AM(R)S and should be operated in frequency band(s) allocated to this service. – CEPT is studying the band 15.4-15.5 GHz and portion of the band 5 000-5 150 MHz

4. CEPT preliminary position on AI 1.3 (3/4) Satellite component Communication between UA and satellite: • the radiocommunication linksbetween UA and satellite have to be considered as an application of the AMS(R)S and should be operated in frequency bands allocated to one of the following radiocommunication services: – AMS(R)S – AMSS – MSS

5. CEPT preliminary position on AI 1.3 (4/4) Satellite Component Communication between UACS and satellite: • Taking into account that for certain applications UACS may be located on ground, on-board ships, or on-board air vehicles, CEPT is of the opinion that applications for CNPC radio communication links between satellite and the UACS have to be considered as an application of FSS and/or AMS(R)S and should be operated in frequency bands allocated to one of the following radiocommunication services : – AMS(R)S – AMSS – MSS – FSS

6. CEPT preliminary position on AI 1.4 (1/2) Resolution 413 • Based on ICAO/ITU-R studies, CEPT is of the opinion that no harmful interference will arise from the introduction of AM(R)S systems in the band 112-117.975 MHz into FM broadcasting receivers below 108 MHz. Resolution 413 should be amended to reflect the results of those studies. • Studies are still ongoing concerning the interference from digital broadcasting sound systems into AM(R)S. CEPT is proposing that this matter will be further pursued under traditional ITU-R activities and outside the WRC process. Resolution 413 should be amended to reflect this. Resolution 420 • Based on the conducted studies within ITU-R, CEPT is of the opinion that spectrum needed to fulfill airport surface network requirements can be met in the current allocation. Therefore no changes are required to Article 5 of the Radio Regulations.

7. CEPT preliminary position on AI 1.4 (2/2) Resolution 417 Sharing studies with non ICAO ARNS systems (considering f) • CEPT is of the opinion that sharing the 960-1164 MHz frequency band between networks in the AM(R)S and non-ICAO national systems in the ARNS would be feasible with frequency off-set and/or distance separation subject to coordination of the AM(R)S networks with the ARNS systems. • CEPT is of the opinion that Resolution 417 should be modified to details the operational and technical means to facilitate sharing between AM(R)S systems operating in the band 960-1 164 MHz and non ICAO ARNS systems Sharing studies with non ICAO ARNS systems (considering g) • CEPT is of the opinion that sharing the 960-1164 MHz frequency band between networks in the AM(R)S and non-ICAO national systems in the ARNS would be feasible and is a matter which can be dealt with in ICAO. Sharing studies with RNSS systems • With the current technologies, and with a sufficient frequency offset and/or distance separation, CEPT is of the opinion that the AM(R)S out-of-band emission can be mitigated to protect the RNSS receiver operating in the 1164-1215 MHz.

8. CEPT preliminary position on AI 1.7 – The results of the studies within CEPT show that the long term AMS(R)S spectrum requirements would not be higher than 3.3 MHz in the forward link and 1.3 MHz in the return link in 2025 over Europe as well as on a global scale. – CEPT has therefore concluded that the AMS(R)S spectrum requirements can be met within the 2x10 MHz of spectrum identified by footnote No. 5.357A, without placing undue constraints on the existing systems operating in accordance with the Radio Regulations. – CEPT is developing a compromise solution between the two options corresponding to the CPM method A and B.

9. CEPT preliminary position on AI 1.12 – CEPT supports the restriction of the mobile allocation in the band 37 -38 GHz to Land and Maritime Mobile. – Sharing studies have lead to a pfd mask required to avoid interference to SRS earth stations that will make the use of any AMS application (including WAIC) impossible in this band. – In addition, AMS receivers would suffer from high interference level when flying above countries where high densities of fixed service links are deployed.

10. CEPT preliminary position on AI 1.25(1/4) CEPT is still investigating sharing possibilities in the frequency bands: - 5 150-5 250 MHz (MSS DL), - 10.5-10.6 GHz (MSS DL), - 13.25-13.4 GHz (MSS DL), - 15.43 -15.63 GHz (MSS UL).

11. CEPT preliminary position on AI 1.25(2/4) Sharing Issues in the band 5150-5250 MHz

12. CEPT preliminary position on AI 1.25(3/4) Sharing Issues in the band 13.25-13.4 GHz

13. CEPT preliminary position on AI 1.25(4/4) Sharing Issues in the band 15.43-15.63 GHz
