Our duties and support for MBB technologies

Our duties: Further the interests of citizens and consumers Ensure optimal use of spectrum Wide spread availability of services Where appropriate by promoting competition and innovation

Our support for MBB Ensure potential and competitive technologies get fair treatment Minimise the barriers to potential technologies.

We recognise that there is a high level of interest from industry for the deployment of LTE

How do we support mobile broadband ?

Seek to understand LTE as a technology Technology co-existence Spectrum and BW requirements for deployment of LTE networks Band plan and consequences of fragmentation

Importance of higher and lower frequencies Consequences of delay and uncertainty

Award spectrum through service and technology neutral market-based mechanisms Benefits to society

romo ng compe on Technical efficiency and feasibility International harmonisation Protecting existing users

Work closely with the industry:

Consultation Tracking the market Participating in standardisation meetings and conferences Leading regulatory activities

Wireless radio spectrum modernisation programme

Government published: Digital Britain Report (DB) Independent Spectrum Brokers Report (ISB).

Waiting for new government to decide whether to proceed with these proposals

Key government proposals: Liberalisation of 2G licenses Combined award of 800 MHz and 2.6 GHz bands with spectrum caps and coverage

obligations 2.1 GHz licenses to become tradable and indefinite

Latest activities: 800 MHz band

Spectrum harmonisation Promoted the usability of digital dividend spectrum for mobile applications during WRC-07. Developed technical conditions now enshrined in the ECs 800 MHz decision Taking significant efforts to make the spectrum harmonised with other European countries

Cable TV interference Work is in progress to:

Identify the severity of interference and the impact to end users Identify the cost and benefits of mitigation measures

Protection clause a set of licence conditions that maximises total value to society of DTT broadcasting and the

use of 800 MHz band spectrum for new services.

Latest activities: 900/1800 MHz bands

The EC has issued a mandate on developing technical conditions for co-existence oftechnologies such as LTE, WiMAX, within the 900/1800 MHz bands and adjacent bands.

Compatibility work carried out by Ofcom lead to change in 3GPPs LTE BS spectrum

masks in 900 MHz band to improve adjacent band sharing conditions

Draft report to the Commission in June.

Latest activities: 2 GHz

EC has issued a mandate to develop the least restrictive technical conditions for 2 GHzbands

This is to allow new technologies such as LTE, WiMAX to co-exist with existing

technologies

Draft report was completed in January 2010 at Copenhagen

Currentl under ECC ublic consultation

The final report will then be passed to ECO for approval and then delivered to the EC

Currently consulting on release of 2010-2025 MHz band

Latest activities: 2.6 and 3.4 GHz bands

2.6 GHz Ofcom took a leading role in developing least restrictive technical conditions for 2.6 GHz

band UK governments Digital Britain report of June 2009 proposed an early release Ofcom is coordinating a program of work to resolve receiver selectivity problem with

Radar.

3.4 GHz band MOD managed spectrum in UK Plan to make re ulations to enable MOD to release s ectrum, if re uested

Consultation was completed on technical conditions of how MOD can release thespectrum in 2009. A statement will be made soon

Summary

We are fully supportive of deployment of MBB technologies such as LTE

Our duties: Further the interests of citizens and consumers Ensure efficient use of spectrum Wide spread availability of services Promoting competition and innovation

Favour awarding spectrum through service and technology neutral market-basedmechanisms. Whilst protecting existing legitimate users

Aim to maximise the value to the society
