Next Generation Network (NGN)
A packet-based network able to provide telecommunication
services
Able to make use of multiple broadband, QoS-enabled
transport technologies
Service-related functions are independent from underlying
transport-related technologies
Enables unfettered access for users to networks and to
competing service providers and/or services of their
choice
Supports generalized mobility which will allow consistent
and ubiquitous provision of services to users

World Radiocommunication Conference 2007
Agenda Item 1.4:
To consider frequency-related matters for the future development of
IMT-2000 and systems beyond IMT-2000 taking into account the
results of ITU-R studies …;
Agenda Item 1.19:
To consider the results of the ITU-R studies regarding spectrum
requirement for global broadband satellite systems in order to
identify possible global harmonized FSS frequency bands for the use
of Internet applications, and consider the appropriate
regulatory/technical provisions, ….
WRCWRC-07 IS STILL CONSIDERING THE FREQUENCY ALLOCATIONS
AT THE TIME OF THE PREPARATION OF THESE SLIDES
