This January is the first anniversary of the
inauguration and operation of the CITEL-8F Electronic Discussion
Forum. The objective of this CITEL electronic forum is to assist in
the coordination of CITEL member preparations for the important work
of ITU-R Working Party 8F (WP 8F) on International Mobile
Telecommunications-2000 (IMT-2000). By sharing draft contributions to
WP 8F and discussion of issues through the forum, CITEL members are
able to be more effective as a group in influencing the work of WP 8F.
Readers from the Americas wishing to join the CITEL-8F forum can do so
here. The next meeting of ITU-R Working Party 8F will be held from
1-8 February 2005 at the ITU Headquarters in Geneva. From 8-15 June
2005 there will be a meeting in the Americas region, specifically in
Québec City, Canada, from 8-15 June 2005 and this will be an excellent
opportunity for CITEL members to participate in this important
activity of the ITU.
IMT-2000 are third generation (3G) mobile systems
which provide access, by means of one or more radio links, to a wide
range of telecommunication services supported by the fixed
telecommunication networks (e.g. PSTN/ISDN/Internet Protocol (IP)
networks), and to other services which are specific to mobile users. A
range of mobile terminal types is encompassed, linking to terrestrial
and/or satellite based networks, and the terminals may be designed for
mobile or fixed use.
Today IMT-2000 is in the first phase of its
deployment. The capabilities of IMT-2000 systems are being continually
enhanced in line with market and technology trends. The future
developments of IMT-2000 and systems beyond IMT-2000 will benefit from
a global approach. We envision new technology concepts for wireless
communications. Coincidentally, there is an increasing trend towards a
convergence of different communication services and systems coming
from completely different backgrounds. Such areas of convergence are,
for example, mobile communications, Internet, broadcasting, wireless
LANs, etc. Each of these represents a variety of applications,
services and delivery mechanisms. These differing information flows
are desired by the users to be available regardless of the means and
manner of delivery. A case in point: Over the mobile phone one is able
to receive voice communications, data messages, browse the web (with
its varying content, such as information from radio and television
broadcast stations), transmit video, listen to MP3 music, etc
It is expected that IMT-2000 will be continuously
developed, and no end-date of this enhancement process is foreseen at
this stage. Evolutionary development of IMT-2000, which refers to the
enhancements of its technical capabilities, range of available
services and breadth of applications, will be progressively introduced
during its lifetime.
These initial enhancements, for which standards are
already being developed, will be followed by further enhancements that
could increase the peak aggregate useful data rate up to approximately
30 Mbit/s.
The ITU view of systems beyond IMT-2000 includes
advanced services. There may be a need for a new wireless access
technology to be developed around the year 2010 capable of supporting
high data rates with high mobility, which could be widely deployed
around the year 2015 in some countries. The new capabilities of
systems beyond IMT-2000 (mobile access element(s) and new
nomadic/local area wireless access element(s)) are envisaged to handle
a wide range of supported data rates according to economic and service
demands in multi-user environments with target peak data rates of up
to approximately 100 Mbit/s for high mobility such as mobile access
and up to approximately 1 Gbit/s for low mobility such as
nomadic/local wireless access. These data rates are targets for
research and investigation.
