WORKING PARTY 4A WORKSHOP ON EARTH
STATIONS ON MOBILE PLATFORMS (ESOMPS)

Summary
CEPT perspective on ESOMPs:
- ESOMPs are not consumer equipment;
- ESOMPs’ benefits to consumers and business;
- Ka-band provides for a natural place for ESOMPs;
- ESOMPs are an FSS application;
- Development and National Implementation of
ECC DEC(13)01 and Report 184.
Some terminology used:
Ku-band FSS: 14.0-14.5 GHz / 10.7-12.75 GHz
Ka-band FSS: 27.5-30.0 GHz / 17.3-20.2 GHz

1. Earth Station on-board Mobile Platforms (ESOMPs)
ESOMPs are what the words say Earth Station On Mobile Platforms
- they are basically Earth Stations:
- use the Fixed Satellite Service infrastructures;
- high data rate ( up-to 10 Mbps↑ // 50 Mbps↓);
- directional antenna (30/40 dBi).
- with the added value of being installed on moving platforms:
- Land: on train, trucks ... ;
- Aero: on aircraft, helicopter ... ;
- Maritime: ships, oil rig ....
- and from a regulatory perspective they can use both MSS or FSS bands:
- CEPT has concluded that these platforms can be deployed in FSS bands.

ESOMPs: Land, Air and Sea
ESOMPs expand the normal FSS and MSS type applications
providing truly broadband services to mobile platforms

2. Benefits for Business and Consumers
- Benefits to Consumers
ESOMPs are new platforms providing truly global satellite services,
thus well apt for bandwidth hungry applications on the go:
- for tablets, smart phones;
- internet, social media, broadcasting, data transfer, ...
- Benefits to Business
In addition to provision of internet, broadcast and data services,
they also provide bespoke applications on:
- land: fleet management, M2M, and pipe for data hungry applications;
- marine: oil platforms, research;
- aero: airline non-safety communications, UAS;
- government use: border control, search and rescue.

3. Ku-band regulatory experience
What did we learn from Ku-band ESV and AES?
- use of FSS platforms to deploy high data rate mobile technology
- internet, TV, telephony - on board trains, aircraft and vessels
- use of highly stabilised antennas
- protect other services (FSS, FS)
- use of harmonised regulatory provisions to protect other services
- ETSI standards, ECC Decisions: e.g. pfd limits, aggregate OOB limits
- require active and automatic control of transmissions
- use of ECO notification measures
- we know who deploys such systems
Ku-band regulatory environment which allows deployment of
professional mobile satellite equipment operating under
FSS platforms resulted in an interference free environment.

4. Comparision Ku-band vs Ka-band technology
Ka-band ESOMPs have:
- Higher satellite performance
- G/T, e.i.r.p. → small beams → higher spectral efficiency
- Smaller equipment / antennas
- lower weight and drag (and lower cost)
- Higher spectrum availability
- more available spectrum (2 x 2.5 GHz) and higher spectrum efficiency
- Lower orbital congestion
- Ku-band been exploited for 20/30 years now
- Bespoke satellite systems
- Global systems and 5x to 10x the data rate per channel
- Higher protection to terrestrial services
- higher terrestrial link margins and higher attenuation

5. Existing CEPT regulatory environment
CEPT(48) promotes free circulation and license exemption for
FSS and AES equipment in C1, Ku and Ka-band.
- Land: Uncoordinated FSS, VSAT, LEST2, HEST3
- ECC/DEC(05)01, (05)08, (06)02, (06)03 & related ETSI standards.
- Maritime: Earth Station on board Vessels (ESVs)
- ECC/DEC(05)09 (C-band) & DEC(05)10 (Ku-band);
- ETSI Harmonised Standard EN 301 447 & EN 302 340.
- Aeronautical: Aircraft Earth Stations (AESs)
- ECC/DEC(05)11 (Ku-band)2 & ETSI EN 302 186.
EU(28) regulatory arena is based on a legally binding framework:
- Framework /Authorisation Decisions → hands-off / light touch;
- R&TTE Directive → presumption on compliance.

6. Adoption of a CEPT regulatory framework
- ECC-Working Group Frequency Management (WGFM)
- Project Team FM44 undertook to study ESOMPs in 2010
with the aim that (see ECC Report 184):
“Any regulatory framework adopted in these bands to
accommodate ESOMPs should also ensure that it does not
prejudice the use of these bands by other FSS and terrestrial
applications operating in conformance with other ECC Decisions.”

WRC03 outcome (see No. 5.516B).

7. ESOMPs are FSS
CEPT decided that ESOMPs are an FSS application
This based on:
- the Ku-band experience, which shows that they are like-FSS;
- the known FSS regulatory environment in Ka-band;
- the need for CEPT to promote innovative technology through convergence
and harmonised approaches for the benefit of all.
ESOMPs that comply with ECC
Decision and ETSI Standard can be
considered as a typical
uncoordinated FSS Earth station.
ESOMPs can operate within the
bands available for uncoordinated
FSS earth stations, do not require
individual license and can circulate
freely in administrations implementing
the applicable Decisions.

9. ECC Report 184
ECC Report 184 on GSO ESOMPs
took three years to study/develop:
- the technical and operational solutions
- the regulatory framework;
Concluded, inter-alia:
- FSS limits - apply also to ESOMPs;
- Land ESOMPs - as Uncoordinated FSS;
- Aero and Maritime ESOMPs - pfd threshold
- Use of 17.7-19.7 GHz band - non-protection
- Network Control Facility (NCF) to ensure protection of other services.

9. ECC ECC DEC(13)01
ECC/DEC/(13)01 adopted 8 March 2013
- Decides 1
- Harmonises ESOMP use within 17.3-20.2 / 27.5-30.0 GHz;
- Decides 2: for Administrations
- designate frequencies for ESOMP use on a national basis;
- provide information to the ECO (e.g. bands, airport operations);
- allow free circulation and exempt from individual licensing;
- Decides 3: provides for technical and operational conditions:
- Annex 1: provides for ETSI standard, max EIRP, NCF, off-axis e.i.r.p,
automatic self-monitoring, ceasing transmission;
- Annex 2: provides for protection of other services e.g. PFD threshold;
- Annex 3: provides for EMC protection to aircraft fields;
- Annex 4: Operator’s notification form to submit to the ECO.

9. ESOMP must comply with R&TTE Directive
ETSI Harmonised Standard EN 303 978
- For Manufacturers
- Ensures an agreed regulated means to test lab their equipment;
- Ensures quick deployment to market and inter-operability;
- For Regulators
- ETSI HS ensure an harmonised framework for equipment
type approval (and CE marking under the EU R&TTE Directive);
- Ensures that other in-band and out-of-band services
are protected at any point in time and space;
- For Service Providers
- Ensures equipment compliance to regulations and health/safety;
- Ensures quick to market access.

11. Conclusion
ESOMPs provide a truly broad-band experience
on mobile platforms and on a global scale.
CEPT confirmed that ESOMPs are treated as an FSS application
provided that these protect existing services
by complying with DEC(13)01 and EN 303 978.
CEPT Administrations are now implementing
DEC(13)01 into their national regulatory framework.
