WP6: Radio Network Aspects

Work Package 6

Radio Network Aspects

The purpose of this work package is to:
• Study and define new network planning rules (frequency allocation, cell size, cell
bit rates) that will support the deployment of denser and localized broadcast networks.
• Define, and develop DVB-T/H very low power transmitters dimensioned
according the results of the first objective
• Define and develop DVB-T/H measurement professional receiver with tools for
QoS measurement taking into account the particularity of the cellular co-siting environment
• To assess potential impact of DVB-H technology on DVB-T deployments

Description of work

The work is distributed in four tasks:

Task 1: Radio network engineering, dimensioning and resource management

Participants will define by means of simulations and measurements network engineering rules that will enable an efficient use of broadcast spectrum. They will contribute to the definition of protection ratio and frequency allocation management. The results will be introduced in the ITU in order to become the basis of an ITU recommendation.

Task 2: Low power complexity transmitters

In support of localised broadcast concepts, low power broadcast transmitter compliant with DVB-T and DVB-H transmission modes will be designed. These transmitters will support the protection ratio and isolation specified in task 1, while the modulators will implement programmability features to support DVB-T and DVB-H configurations. Moreover, the capability to insert local data has to be taken into account in order to optimise both the performance of the cell but also to reduce drastically the price of such equipment.

Task 3: DVB-T+/H and cellular co-siting

A measurement receiver will be designed and interfaced to protocol analysers. This measurement receiver will allow having a reference tool for measuring the QoS particularly in shadow areas and at cell coverage borders. Used as network probes, such equipment will be used for dynamic Grade-of-Service optimisation.

Task 4: DVB-T+/H radio network aspects

This task will constitute a first step for validation of technologies and options chosen by DVB-H ad hoc standardisation group for defining a new DVB physical layer standard. Elaborating on targeted frequency bands and associated dedicated mobile channel models will be required as a first step towards handset integration of the new standard. Then the criteria for technology assessment, using software simulations and theoretical evaluations (targeted bit error rate, complexity, compatibility or evolution path for existing DVB-T infrastructure, etc.) will need to be defined according to the foreseen broadcast network configurations. Finally the standard will be evaluated and a final report on expected standard performances and impact of identified options produced.
