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

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-Ts 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, Johns 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
