Spectrum for wireless broadband – 5G
ECC has recognised in its strategic plan for 2015-2020 the importance of spectrum for wireless broadband and 5G. This page outlines the CEPT roadmap for 5G and the corresponding ECC activities
This page contains the following information:
1. What is 5G?
ECC has recognised the importance of the fifth generation of mobile technology referred to as ‘5G’ (also known as IMT-2020). 5G is listed as one of the major topics in the ECC strategic plan for 2015- 2020.
Regulators, standards bodies, industry and academia are currently discussing 5G and working to develop it further. 5G aims to provide seamless coverage, high data rate, low latency, low power and highly reliable communications. Use cases under consideration include enhanced mobile broadband, massive machine type communications (M2M) ,Internet of Things (IoT), healthcare, home automation, industrial automation and sensors. Vertical dimension will be added from the user’s perspective.
5G technical requirements
The aim of 5G is to improve on the performance of previous generation systems. As described in ITU-R Recommendation M.2083, the general performance objectives can be quantified as follows:
- Peak data rate: tens of Gbit/s
- User experienced data rate: 100 Mbit/s to 1 Gbit/s
- Connection density: 1 million connections per km2
- End-to-end latency: millisecond level
- Traffic volume density: 10 Mbit/s per m2
- Mobility:up to 500 km/h
Different players from various ‘vertical’ domains (i.e. different industry branches) can be brought together using the 5G ‘slicing’ concept. The network capabilities are intended to match the requirements of the different vertical players.

2. CEPT roadmap for 5G - Relevant ECC activities
The 43rd ECC Plenary meeting in Prague, 15-18 November 2016, approved a comprehensive list of actions regarding the fifth generation of mobile technology (5G) named the CEPT roadmap for 5G. The latest version of the roadmap includes the update performed during the 44th (28 February - 3 March 2017) and 45th (27-30 June 2017) ECC Plenary meetings to reflect the progress of ECC activities.
It outlines the CEPT’s actions for 5G, taking into account the views from all stakeholders expressed during the CEPT Workshop on 5G from 2-4 November 2016 in Mainz.
The roadmap outlines the main targets to be addressed by CEPT regarding harmonisation of spectrum for 5G, preparation for WRC-19 agenda item 1.13 regarding IMT above 24 GHz, consideration of vertical industry needs and other spectrum challenges.
It also identifies, when appropriate, the related ECC activities (such as Work Items (WI) in the ECC Work Programme) and the areas where further considerations are expected.
Harmonisation measures for 5G
As identified in the CEPT roadmap, work has been initiated within ECC PT1 on harmonisation measures for 5G in a first set of bands:
- 3.4 – 3.8 GHz: this band is already harmonised within Europe for Mobile/Fixed Communication Networks (MFCN) through ECC Decision(11)06. Activities are ongoing to assess the suitability to 5G of the harmonised technical conditions contained in this Decision. It is also intended to develop guidelines to help administrations in solutions for defragmenting the 3.4-3.8 GHz band, in which there are existing licences in many CEPT countries and for developing plans and intended timescale for the future utilisation of this band.
- 24.25-27.5 GHz: CEPT has identified the 26 GHz band for early European harmonisation, as it provides over 3 GHz of contiguous spectrum and more favourable propagation than the higher frequency bands under consideration. Compatibility and protection, as appropriate, with all existing services in the same and adjacent frequency bands, in particular the protection of existing and future EESS/SRS earth stations should be addressed. As a result, ECC PT1 has recently been tasked to start developing an harmonisation decision setting the conditions for the introduction of 5G in the 26 GHz band.
EC Mandate on 5G
In December 2016, the European Commission issued a Mandate to CEPT to harmonise technical conditions for the development of EU-wide 5G equipment. The Mandate addresses the same bands identified in the CEPT roadmap (3.6 GHz and 26 GHz), so there is a link to the existing harmonisation activities within ECC PT1 as outlined above. ECC PT1 will develop 2 CEPT Reports on harmonisation measures to be sent to the EC by June 2018 for adoption in relevant EC regulations.
Related activities on harmonisation measures for MFCN
40 MHz of spectrum for supplementary downlink (SDL) for MFCN has been harmonised in 1452-1492 MHz through ECC Decision(13)03. Ongoing work in ECC PT1 is examining the potential for harmonisation in the surrounding frequency bands (1427-1452 MHz and 1492-1518 MHz) in order to provide a total of 89 MHz of contiguous harmonised spectrum for MFCN.
Preparation for WRC-19 and related ITU-R activities
Due to the fact that 5G envisages very high data rates, much larger bandwidths than ever before will be required (up to several GHz), which can only be found in higher frequency bands above 24 GHz. CEPT participated in the intensive debates on this issue during the preparations and in the course of WRC-15. The outcome of the Conference was a Resolution to focus on specific frequency bands, as proposed by CEPT, under agenda item 1.13 for WRC-19.
ECC PT1 has been tasked with the responsibility of CEPT CPG preparation for this agenda item and has started discussion on prioritisation of these bands, and is participating in the relevant ITU-R activities in Task Group 5/1.
Compatibility and sharing studies with other systems in the following bands, identified by WRC-15 for future wireless broadband usage (including 5G), will be considered at the European level:
- 24.25-27.5 GHz
- 31.8-33.4 GHz
- 37-43.5 GHz
- 45.5-50.2 GHz
- 50.4-52.6 GHz
- 66-76 GHz
- 81-86 GHz
The current usage of these bands and initial prioritisation for study were the subject of a recent ECC PT1 questionnaire. A summary of the results of the questionnaire are available here. Many respondents were of the view that the bands below 43.5 GHz (i.e. 24.25-27.5 GHz, 31.8-33.4 GHz and 40.5-43.5 GHz) should be prioritised for early studies, whereas others believe that no prioritisation of bands for study is necessary at the early stage.
Identification of suitable bands will need to address compatibility with existing systems in the same and adjacent bands, and migration of existing usage if required.
In addition, ECC PT1 is actively participating in ITU-R activities on IMT-2020/5G in WP 5D. The work is currently at an early stage, and is focussing on technical requirements and evaluation methods. 5G technology developments will be considered at the upcoming meetings.
Other issues to address
The CEPT roadmap identified several actions addressing the requirements of vertical industries in the context of 5G (e.g. PPDR, industrial automation, automotive, utilities, rail, …). They are expected to be considered, as appropriate by ECC PT1 and WG FM in their related activities.
Other issues, such as satellite solutions for 5G, new sharing opportunities and challenges (e.g. MIMO), considerations on authorisation regimes, infrastructure and backhaul requirements for 5G will also need to be addressed.
The ECC strategic plan, with additional guidance from the ECC Steering Group, tasked ECO to engage with relevant research activities focusing on 5G. In this context, ECO has agreed to participate in the advisory board of the COHERENT project. This is one of the H2020 5G-PPP projects funded by the European Commission, which aims to research, develop and showcase a unified programmable control framework for 5G heterogeneous radio access networks.
3. Relevant ECC regulations
Existing harmonised spectrum for MFCN
ECC has already harmonised more than 1200 MHz of spectrum for mobile broadband in the frequency range from 694 MHz to 3.8 GHz. Bands within this frequency range have been under study for almost 20 years with an aim to increase the availability of bands for mobile broadband.
Relevant MFCN deliverables for frequency bands of interest can be viewed in this document, or by using the EFIS search function (select ‘MFCN’ under ‘level 2 application terms’).
In the future, there may be a need to adapt the harmonised regulatory framework in these existing frequency bands to account for 5G (e.g. to accommodate the needs of networks based on small cells). Whilst the work has started for the bad 3.4-3.8 GHz, further considerations are expected at a later stage from ECC PT1 in the other frequency bands (700 MHz, 800 MHz, 900 MHz, 1500 MHz, 1800 MHz, 2.1 GHz, 2.3 GHz, 2.6GHz) as part of the review process of the corresponding ECC Decisions.
4. Additional background information on 5G
CEPT workshop on 5G
On 2-4 November 2016 the ECC held a workshop to discuss 5G developments and requirements.
The aim of the workshop was to establish CEPT’s priorities for 5G, taking into account views from all stakeholders, including international organisations, standardisation groups, mobile industry and vertical industry members. Views on ongoing 5G developments outside Europe were also introduced.
It was a successful three days and the draft CEPT roadmap for 5G was defined as a result of all the presentations and discussions (see section 2 above). Material from the workshop is available on our website as follows:
