From:	Peter Adams, Delegate from ITU-R TG 8/1 who attended the Beijing meeting.

ITU-R TG 8/1 has endorsed the Operators Harmonisation Group (OHG) as
a good thing and something we fully support and agree with. I understand
that the 3GPP TSG RAN did the same thing last week. 
Harmonisation in the TDD bands is undoubtedly more difficult. However we have 
managed to get both the UTRA components classified by the OHG and the ITU as 
W-CDMA systems where progress has been more positive. For the terrestiral case, 
the five IMT-2000 family members ITU-R TG 8/1 is aiming for are:

1.  W-CDMA FDD - Direct Sequence (DS) Mode - Harnonised UTRA / CDMA 2000.
2.  W-CDMA FDD - Multi-Carrier (MC) Mode - CDMA 2000 only.
3.  W-CDMA TDD - Based on ETSI's hybrid TD-CDMA system (i.e. also strongly
linked to UTRA).
4.  UWC 136 TDMA system (based on GSM EDGE technology i.e. again an ETSI
system).
5.  DECT - also clearly an ETSI system (which is TDMA based).

        Of course, the Chinese TD-SCDMA system will also have to be merged
in with the above.

        The fundamental objective remains, of course, to achieve global
roaming and interoperability with a sufficiently small number of systems to
keep multi-mode terminals down to an acceptable cost (when manufactured in
bulk). To achieve this objective, there will need to be some compromises on
cost, design and performance. However to achieve the fundamental objective
above, many major operators and manufacturers alike have seen the OHG work
as a good thing to be encouraged.

        Arguably OHG is one of the bodies which is saving 3G from over
fragmenation at the moment. The initiative during 1998 to set up 3GPP is
clearly another important move in the same direction. Hopefully we are now
well on the way to achieving a truely global 3G family of systems. ETSI and
its members clearly have an important role to play in all these
organisations and I believe many are doing so.
