Cognitive Radio: A Broadcaster’s Perspective (RTE) [Johnny Evans]

Cognitive Radio: A Broadcaster’s Perspective July 21 st 2010 [email_address]

ComReg’s innovative approach
Early identification of potential of cognitive radio
2007 document Dynamic Spectrum Access
2001 Cognitive radio identified along with Software Radio
Wireless test and trial
Digital Dividend
Statement of strategy Consultation 2010
Spectrum liberalisation

Cognitive Radio and Broadcasting
Cognitive approach is not yet needed/possible for terrestrial broadcasting:
High powers, high sites
requires stability
regulatory certainty

Cognitive Radio and Broadcasting
Cognitive technology a good fit for services ancillary to broadcasting:
Short term use
Portable/Mobile
Low Power
Some of the related technologies could drive innovation in broadcasting:
Opportunity to integrate broadcast platforms into mobile/portable devices
Multi-standard broadcast receivers (DAB, DMB, DVB, DVB-T2, etc)

New Neighbours for Broadcasters
Broadcasters are naturally worried about their new neighbours in the UHF band:
Will there be interference? (Co-channel, adjacent channel, blocking)
Will the interference be transient?
Will this limit the ability of broadcasting to develop/innovate?

Regulatory Developments
Spectrum management – some welcome developments:
Geolocation database approach should be applied first, ahead of autonomous sensing (CEPT SE43)
Careful management needed by regulators
Resource implications
Further studies/recommendations on cognitive radio (ITU WRC-2012)

Managing Spectrum For Broadcasting
Social/Cultural Value of Spectrum – effective spectrum use
Importance of public service broadcasting
Further development of terrestrial broadcast services:
DTT just getting started
HDTV forthcoming
3D TV ? (Trials in UK on DTT)
Digital Text and Interactive services
Mobile TV
