Digital dividend from broadcasting and mobile perspectives
This session will provide an overview of the current harmonization efforts towards analogue television switch-off in the different ITU regions and also a discussion of the harmonization landscape for mobile broadband in the digital dividend spectrum.
Overview
Digital Dividend ≠ Digital Divide!
OverviewDigital Dividend: digital terrestrial TV
Use spectrum more efficiently: more TV in less spectrum
More spectrum for mobile broadband: 4G
Innovative radio technologies: white space
Europe + Africa: GE06agreement for digital broadcasting
• 2001 – ITU Council decided to plan for digital broadcasting in the European Broadcasting Area (ST61)
• 2002 – decided to include countries in Africa and Middle East
• 2002 – RCC countries included by Plenipotentiary conference (Marrakesh)
Europe + Africa: GE06agreement for digital broadcasting.Plan for 120 countries
Europe + Africa: GE06Agreement
TV frequency bands in question:
VHF Band III: 174-230 MHz
UHF Bands IV & V: 470-862 MHz
Technology: Digital Video Broadcasting (DVB-T)For television with four reception modes of fixed, mobile, portable indoor and outdoor
In Europe + Africa: GE06Agreement. Objectives
- Agree on date for Transition to Digital- Establish a digital frequency plan- Adopt an Agreement that sets out the procedures for
making changes to the frequency plan and to bring the frequency assignments into operation.
Europe + Africa: GE06Agreement
The Agreement entered into force on 17 June 2007
Transition: 17 June 2015, but some countries preferred an additional five-year extension for the VHF band (174-230 MHz).
At the end of the transition period, countries may continue to operate analogue broadcasting stations provided that these stations
do not cause unacceptable interferencedo not claim protection

World overview: DTT adoption
Analogue switch off: spectrum decisions for mobile broadband
Implications: hardware availability
More digital TV… less analogue hardware
New mobile technologies… market choices

4G mobile broadband landscape
USA: 698 – 806 MHz(2 x 12 MHz blocks + 2 x 11 MHz blocks)
Europe: 790 – 862 MHz (2 x 30 MHz blocks with 11 MHz center gap)
Asia Pacific: 698 – 806 MHz(2 x 45 MHz blocks with 10 MHz center gap)
4G mobile broadband landscape
LTE & WiMax(channel sizes up to 20 MHz for maximum data rate≈ 100 Mbps)
