CEPT CPG decides position on 144, 50 and 1240-1300 MHz

CEPT Logo“At the insistence of the European Commission, a WRC-23 agenda item was considered necessary to address the world-wide protection of Regional Navigational Satellite Systems from amateur emissions in the band 1240-1300 MHz.”

The CEPT ECC CPG met in Ankara during August 26-30 to finalise their position ahead of the ITU World Radiocommunication Conference 2019 (WRC-19) to be held in Sharm el-Sheikh, Egypt, October 28 to November 22. This conference will define the Agenda Items for WRC-23.

RSGB volunteers along with other radio amateurs in IARU Region 1 countries put in a considerable amount of work to defend the amateur radio allocations. Their hard work ensured the removal of 144-146 MHz from a study of additional spectrum for aeronautical applications and an agreement on a European Common Proposal for 50-52 MHz.

IARU Region 1 have released this report on the meeting:

The CEPT Conference Preparatory Group met this week in Ankara, Turkey. Items of interest to the amateur service which were finalised were:

– Agreement to a European Common Proposal (ECP) on allocating 50-52 MHz to the amateur service in Region 1 on a secondary basis with a footnote listing those countries where the amateur service will have a primary allocation in the band 50-50.5 MHz (WRC Agenda Item 1.1)

– Agreement to an ECP on spectrum to be considered for International Mobile Telecommunications, which does not now include the primary amateur band at 47-47.2 GHz (WRC Agenda Item 1.13)

– Agreement to an ECP that retains the current regulatory position in the 5725-5850 MHz frequency band which includes secondary allocations to the amateur service and the amateur-satellite service (WRC Agenda Item 1.16)

– Removal of 144-146 MHz from a French proposal for study of additional spectrum for aeronautical applications. (WRC Agenda Item 10)

– At the insistence of the European Commission, a WRC-23 agenda item was considered necessary to address the world-wide protection of Regional Navigational Satellite Systems from amateur emissions in the band 1240-1300 MHz. A draft WRC Resolution was agreed which underlines the importance of this frequency band to the amateur service and explicitly excludes the removal of existing allocations as part of the proposed agenda item. (WRC Agenda Item 10)

– There was no change to the already agreed CEPT position on Wireless Power Transmission (WRC Agenda item 9.1.6). This states that no change is needed in the Radio Regulations to address the question of operating frequency for WPT-EV, but leaves open the question of spurious emissions from WPT-EV.

Commenting on the outcome of CPG, IARU Region 1 President Don Beattie, G3BJ, said that the IARU team at Ankara (the only representatives of the amateur service at the meeting) had presented clear and convincing arguments for the amateur service position and he was pleased that regulators had recognised the strength of the amateur case. He expressed his thanks to everyone who had contributed to the outcome at CPG.

The issues now move to WRC in Egypt in November for final resolution. IARU will be there.

Note: Although the CEPT position includes a Primary allocation at 50.0 to 50.5 MHz it is for the Amateur Service only – the Amateur Satellite Service is excluded.

New French CEPT paper still seeks 144-146 MHz for Aeronautical

CEPT LogoThe French administration has renewed its attack on the Amateur Radio 144-146 MHz band ahead of a key CEPT ECC CPG meeting in Ankara, August 26-30.

In a paper to be considered at the conference the French Administration says it is not at this time seeking Primary status for the Aeronautical Mobile Service in 144-146, however, their intent is still that the Aeronautical Mobile Service should share the amateur 2m band.

It is clear where such sharing would inevitably lead, amateur operation in the band would only be tolerated if there were no interference to Aeronautical Mobile. Radio Amateurs might be subject to heavy restriction and low EIRP limits.

We can get on idea of France’s long term intent for 144 MHz from their attitude to the 1240-1300 MHz band. It was initially said the Galileo constellation could amicably share this allocation and amateur operation could continue but now France says “unregulated use of the band 1240-1300 MHz by the amateur service is a serious source of harmful interference to RNSS receivers.”

Threat to Amateur Radio 23cm band

Galileo LogoA joint paper by France, Lithuania, Malta, Slovenia and The Netherlands for the CEPT CPG meeting in Ankara, August 26-30, attacks the continued use by Radio Amateurs of our 1240-1300 MHz band.

This is the final CEPT CPG meeting in preparation for the ITU World Radiocommunication Conference 2019 (WRC-19) to be held in Sharm el-Sheikh, Egypt, October 28 to November 22. This conference will define the Agenda Items for WRC-23.

Paper AI10 – Proposal on AS-RNSS says:

Galileo is close to full operational capability and its E6 signals in the band 1260-1300 MHz will support new services such as the free-to-use Galileo High Accuracy Service, and also robust authentication, expected to be used by a variety of applications including autonomous vehicles and the Internet of Things (IoT).

Several cases of interference to Galileo E6 receivers from amateur service emissions have occurred in the recent past, sometimes at significant distance, and have taken several hours or even days to be eliminated. There is therefore a serious concern that as Galileo E6 receivers are deployed and used more widely, cases of interference from amateur stations will rapidly grow in number.

A WRC-23 agenda item is necessary to address this issue because:

1. Unregulated use of the band 1240-1300 MHz by the amateur service is a serious source of harmful interference to RNSS receivers. This is demonstrated by experience.

2. The number of Galileo receivers in 1260-1300 MHz will increase dramatically, and interference cases will multiply if not addressed timely.

3. Galileo and other RNSS systems will deploy at global scale, and interference scenario between amateur emissions and RNSS receivers include cross-border cases. The issue is therefore of international nature and is to be addressed in the ITU framework.

4. Galileo is a major European asset, and a decision at WRC-23 is essential to be compatible with the roadmap of deployment of Galileo receivers in this band.

SSA defends 23cm band against Galileo threat

Galileo LogoSweden’s national amateur radio society, the SSA, has sent a supplementary letter to the communications regulator PTS ahead of the next meeting of the CEPT ECC Conference Preparatory Group CPG-19.

The SSA report:

At a previous CEPT meeting (PTA), France has proposed an agenda item to WRC-23 that the coexistence between satellite navigation (eg Galileo) and amateur radio in the band 1240-1300 MHz should be investigated. The proposal was voted down at the preparatory PTA meeting, but France has now sent letters to the various telecommunications authorities with a request that they now support this proposal at the forthcoming CPG19-9. SSA opposes this.

SSA has therefore sent a supplementary letter to PTS about our 23 cm amateur band. Our section leader for IARU and VUSHF Mats SM6EAN explains the background and our opinion on our section pages. Here you can also read the new letter to PTS.

144 and 1240 MHz bands – WRC-23 Agenda Items – Update

IARU was represented at the meeting of CEPT Project Team A (responsible for some aspects of the CEPT position for WRC-19), held in Prague from June 17-21.

The IARU Region 1 website reports:

Of particular interest were discussions on two proposed Agenda items for WRC-23, concerning the sharing of the 1240-1300 MHz band with the Galileo navigation system and the proposal from France to study a range of frequencies, including the 144 MHz amateur band, for future aeronautical applications.

The output from PTA does not carry forward the Galileo proposal, but it is likely that further discussions will take place prior to the Conference Preparatory Group meeting in August. Meantime work on this issue will also continue in other specialist CEPT forums. IARU will continue to support this approach and it believes this will be the most efficient method for developing the sharing guidance required to protect Galileo operations in a timely manner.

Regarding new aeronautical frequencies (including 144-146 MHz), the proposal was not strongly opposed by administrations and has been carried forward to the higher level CEPT Conference Preparatory Group (CPG) meeting in August for final adoption.

IARU views with grave concern any proposal to include the 144 MHz band in the proposed aeronautical agenda item and will be making every effort to fully protect amateur radio interests and seek the support of regulators in this regard.

The band 144-146 MHz is allocated globally to the amateur and amateur satellite services on a primary basis. It is the only globally harmonised VHF band for the amateur and amateur satellite service. As such it is an important and widely used part of the amateur spectrum with a vast installed base of both terrestrial/maritime amateur users and systems and operational satellite stations including the International Space Station (ISS).

This heavily used band supports a large number of repeater stations, segments for weak-signal long distance terrestrial and EME (Earth-Moon-Earth) communications, satellite and ISS usage, data services, as well as conventional terrestrial and tropospheric communications. The Primary status of the band has also enabled a number of amateur aeronautical uses including on manned flights and high-altitude balloons. Supporting all of this is a wide variety of commercial and experimental equipment, ranging from ultra-low noise preamplifiers for sensitive receivers, software defined radios and transmitting systems that can deliver high EIRP levels when needed to overcome high loss propagation paths.

Given the propagation to/from an aircraft at altitude, it is entirely possible that harmful interference to sensitive amateur and amateur satellite receivers will be caused over a 1,000 km radius of a single aircraft.

IARU will shortly be providing a brief to Member Societies and other interested parties, asking them to discuss the French proposal with their administrations well in advance of the August CEPT-CPG meeting.

It is possible that France will seek to introduce into other Regional Telecommunications Organisations (RTO) the same proposal to study the 144-146 MHz band for aeronautical use. IARU will provide a brief shortly to enable representations to be made to administrations in countries under those RTOs for protection of this amateur spectrum allocation.

1240-1300 MHz band discussed by CEPT WGFM and CPG/PTA

WRC-2000 saw the Galileo Global Navigation Satellite System (GNSS) get an allocation at 1260-1300 MHz. This was the same ITU conference that saw 432-438 MHz being allocated for satellites that carry Synthetic-Aperture Radar (SAR) systems.

In January 2006 Peter Blair G3LTF published a paper Potential Interference To Galileo From 23cm Band Operations. This described the proposed Galileo system design and its applications with particular reference to the E6 (1260-1300 MHz) band. It described the operation of typical Galileo receivers and their ability to deal with interference and gave practical illustrations of these effects.

The 30-satellite Galileo system (24 operational and 6 active spares) is expected to be completed by 2020.

A paper at the CEPT WGFM meeting #93 held in Rome, February 4-8, 2019, titled Coexistence between AS [Amateur Services] and RNSS in the Frequency Range 1260-1300 MHz said:

At the most recent meeting of CPG/PTA #5 in September 2018 the European Commission provided a proposal for Agenda Item 10 of WRC-19 on the amateur service allocation in L band. The EC contribution (CPG/PTA(18)080) proposed to consider an extension of the spectrum allocation to the amateur service on a secondary basis in the range 1300 – 1350 MHz. Germany announced at that meeting that a measurement campaign was already planned to investigate further the coexistence of applications in the amateur service and the radionavigation-satellite service [RNSS] particularly in the frequency range 1260 – 1300 MHz.

Since then these measurements were carried out at the premises of the “Universität der Bundeswehr München” (University of Federal Armed Forces Munich) mid December 2018 and a report on the issue is in preparation. At CPG/PTA #5 the meeting agreed to wait for the results of the measurement before taking any further action. Currently the measurement data is being processed and the results will be reported to CPG/PTA #6 in April 2019. Germany would offer to present this report also to WG FM.

Depending on the results the issue could become an enforcement issue for CEPT and, hence, may become a topic for further consideration in WG FM and WG SE.

https://cept.org/Documents/wg-fm/49268/fm-19-069_information-on-measurement-campaign-on-as-gnss-in-1260-1300-mhz-germany

The CPG/PTA meeting #6 held in Bucharest April 1-5, 2019, saw this proposal:

PTA is asked to consider the results of these tests to determine if appropriate actions are required.

A possible action could be to propose a new Agenda Item for WRC-23 to address the issue. The subject could be: to consider the possible additional spectrum allocation to the amateur service on a secondary basis above 1300 MHz (or in another frequency band to be determined), with a view to progressively migrate the radio amateurs services from the band 1240-1300 MHz to the new band. To study an ITU recommendation for the coexistence of services in the band 1240-1300 MHz in the short/medium term.
