services within the planning area. These include airborne military services and television
services in the VHF bands as well as fixed and aeronautical telemetry in the L-Band.
Overall, there were sufficient allotments made in the Wiesbaden plan for the initial needs
of DAB, but looking ahead, additional frequency allocations will be needed in Europe.
Most organisations planning to launch today and expand T-DAB services favour VHF
frequencies.
The position on T-DAB frequencies in other parts of the world is similarly complicated
and underlines the point that frequency allocation is an outstanding issue that will remain
high on the DAB agenda for some time to come.
At the International Telecommunications Union (ITU) in Geneva, the Regional
Radiocommunications Conference 2006 (RRC-06) took place from 15 May to 16 June
2006. The new agreement, GE06, includes the frequency plans for T-DAB and DVB-T in
Band III and for DVB-T in Bands IV/V for Region 1 (parts of Region 1 to the west of
meridian 170°E and to the north of parallel 40°S) and in the Islamic Republic of Iran (see
Figure 4.18 below).
