June 7th - 10th 1999, UMTS 99, Monaco: - On the eve of this years
UMTS 99 conference in Monte Carlo, cross-industry group the UMTS Forum
has welcomed proposals by the Operators Harmonization Group (OHG) for
a single global framework of technical standards for third-generation
Submitted recently to the International Telecommunication Unions Task
Group 8/1, the OHG proposal outlines key technical parameters that will
assist the rapid evolution from existing second-generation mobile systems
to high speed (up 2Mbit/sec) multimedia-capable third generation (3G)
networks that will facilitate tomorrows wireless Information Society.
Crucially, the OHGs proposal caters for three operational modes based
on a unified Wideband CDMA third-generation standard. Direct Spread
(DS) and Time Division Duplex (TDD) modes allow operators to make use of
paired and unpaired spectrum already identified for IMT-2000. Definition
of technical specifications for these modes is already progressing within
the Third Generation Partnership Project (3GPP), the global body bringing
together worldwide standards bodies in which the UMTS Forum is a market
A third Multi Carrier (MC) mode within the OHG proposal provides a smooth
evolutionary path to third-generation for operators of IS-95 networks.
This extremely positive proposal helps keep third-generation network
launches on schedule by assuring an optimised use of resources and a
simplified standardisation process, commented UMTS Forum Chairman Dr
Bernd Eylert. Within the Forum we also applaud the Operators with their
market-led approach to defining requirements for a family of interoperable
third-generation standards. Furthermore, the OHG proposal represents
an approach that allows all regions to deploy their own 3G solutions
without technological compromise.
It is anticipated that standardisation work will be completed within
the ITU before the end of this year, clearing the way for the successful
market introduction of UMTS services within the timeframe as originally
envisioned by the UMTS Forum. According to its own studies, the Forum
believes that this global market for wireless multimedia will exceed
1.7billion users by the year 2010.
A unified global 3G standard pays immense dividends for all players,
continued Dr Eylert. Existing operators are afforded a seamless
evolutionary path from second-generation systems, while end users will be
able to benefit from enhanced interoperability between third-generation
services as they roam worldwide.
