Benefits of international harmonisation

• Economies of scale

• Technical efficiency

• Consumer convenience

Harmonisation - technical efficiency

When different types of service use the same part of the spectrum, large amounts of land can be sterilised and then can’t be used for either type of service.

European regulatory framework for radio spectrum and equipment

Read more athttp://apps.cept.org/eccetsirel/

Roles of the three European regulatory organisations

CEPT/ECC:Consensus and voluntary characterSpectrum designation to systems/applications and technical conditions for its use (48 member countries)

European Commission:Single market issuesBinding regulations based on the technical expertise of CEPT/ECCand harmonised standards of ETSI (28 Member States)

ETSI:European Harmonised standards (EN) for radio equipment‘System Reference Documents’ (SRDoc) which inform and trigger much of the CEPT/ECC work(over 700 industry members &and European naitonal regulators)

ECC Strategic Plan

Concentrate on:

• Expertise

• The European approach to ITU

• Cooperation with European Commission

• Providing a focal point for information (EFIS etc.)

• Cooperation with other bodies Review Strategic Plan before end-2014

ECC tackles topics with big public impact

• Mobile broadband

• Broadcasting

• Cognitive radio

• Public protection and disaster relief

• Short range devices

......and many more: wireless microphones, environmental satellites, and so on, and so on

Harmonised bands for wireless broadband

470-700 MHz (‘whole sausage?’)

700 MHz (everyone?) 60-92 MHz

800 MHz Digital Dividend up to 60-65 MHz

900MHz GSM -> ECS Band 50-70 MHz

1452-1492 MHz ‘L-Band’ (SDL) 40 MHz

1800MHz GSM -> ECS band 150 MHz

2100 MHz IMT (-> ECS) 160 MHz

2300 MHz ECS with LSA up to 100 MHz

2600 MHz IMT (->ECS) 190 MHz

3.4-3.6-3.8 BWA -> mobile 400 MHz

UHF long term vision?

Wireless broadband: developing the concept

• Supplemental downlink

• Wi-fi and ‘traffic off-loading’

• Licensed shared access

• Cognitive radio

On 5G, we are already considering it, but we start with an open mind

Wi-fi and traffic offloading

Paying bills is a turn-off(but income pays for investment)

Wi-fi and small cells: capacity for operators, as well an alternative to bypassing them?

Short range devices

Main trends in evolution of EC Decision on SRDs:

• Old arrangement – many narrow frequency blocks• New arrangements – more emphasis on wider, more

generic blocks, with similar technical characteristics• Take more account of characteristics such as duty cycle

Next steps could include more use of ‘cognitive’ elements (e.g. LBT etc.)

Tendencies for SRD applications’ use of mitigation techniques

Example: New band plan 870-876 MHz (from ECC Report 189; work triggered by ETSI SRdocs )

Also: ECC Report 182 (Survey about the use of the frequency band 863-870 MHz)Duty Cycle Mitigation is dominating – Sensing is not part of it !

A valid incremental step already in action, taking advantage of what technology can deliver. Not seen as ‘magic’ or ‘paradigm transformational’
