Future Work (I)
At WTSA-2000, prediction that
mobile would soon outnumber
fixed subscribers led to
establishment of SSG
–
–
Became global reality in 2002
Today, nearly all subscriber growth is mobile
WTSA-2004 recognized importance of mobility by
upgrading SSG to SG 19
NGN has mobility as a fundamental capability
–
Mobility-related studies should continue as a discrete
and highly visible block of work
Note — 2007 data are estimates.

Future Work (II)
Key industry “megatrends”:
–
Everyone and everything is always connected
Range of devices, entities on the net far outpaces the number of
people consuming the services they offer
–
Supported by telecoms enabled applications
Reinvented services & applications, network-aware intelligence,
IMS* and SOA**: intuitive user experience
–
Supported by ubiquitous high speed access
Seamless communications experience: anywhere, anytime, any
convenient device, and economical
Industry directions point to two “super” work groupings
with sub-groups as needed:
–
–
Telecommunications Enabled Applications
Infrastructure / Transport
Timely global standards are essential!

Conclusion
Telecoms / ICT is entering a new era
–
Megatrends: hyperconnectivity supported by
telecoms enabled applications, seamless
broadband for everyone
Mobility is fundamental
–
Next 1B subscribers will all be mobile
Essential to recognize industry trends and
organize accordingly
–
ITU-T’s relevance and future success depends
on it!

Thank you!
John has served ITU-T in various roles and positions over the past 24
years, including appointment at WTSA-2000 as Chairman of the Special
Study Group (SSG) on “IMT-2000 and beyond”. When the SSG became
SG 19 at WTSA-2004, John was appointed its Chairman.
Throughout his career at Nortel, John’s ongoing close coupling with
design, product line management and marketing teams has been an
essential element of his successes in standards. John has also had extensive involvement
in ANSI T1, TIA TR45, 3GPP2, and has participated in ITU D, ITU R, 3GPP, APT and the
WiMAX Forum among others.
John leverages his standards leadership in working with ITU-D and ITU-T in organizing,
chairing and presenting at seminars and workshops on 3G, Next Generation Networks
and other topics around the world. In the past five years, he has been involved in some
13 such events (chairing many of them) and has given over 60 presentations around the
world, including Europe, the CIS countries, the Middle East, Africa, Asia-Pacific, and the
Americas.
John earned a Bachelor of Applied Science in Electrical Engineering from the University of
British Columbia in 1973. He served as a communications engineer with the Canadian
Armed Forces, achieving the rank of Captain. John joined Bell-Northern Research, the
R&D arm of Nortel, in 1978. He is currently part of Nortel’s Strategic Standards Team in
the CTO Office, and is based in Ottawa, Canada.
John is a Registered Professional Engineer in Ontario, Canada, and is a member of IEEE.
