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)

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
