Challenges:
Common Network that can be
completely
scalable to adopt to all the services
External network that makes the
roaming facilitated with additional value
added services to justify the roaming.
QOS and Security issues are going to
stay….
Evolving Networks – Value Proposition

11.  Multimode network
2G/2.5G/3G/4G/…
 Multimode terminals

20. “Fifteen Years is the average period of probation, and during
that time the INVENTOR, the PROMOTER, and the INVESTOR,
who see a great future, generally lose their shirts…. This is
why the wise capitalist keeps out of exploiting new
inventions and comes in only when the public is ready for
mass demand”
Owen D. Young, a GE executive who carried out the purchase
of American Marconi

21. “If the INVENTOR, the PROMOTER, and the INVESTOR understand
the mass market from different perspective, keeping cost,
complexity and commercialisation in mind from
conceptualisation stage to commercialisation stage will
make a huge traction for the capitalists throughout the
period of probation”
J.Ravikumar
