Applications and Drivers
! Mobile operators actively building out IP/MPLS core networks
Capex and ongoing opex savings consolidate multiple networks
Migration of SS7 over IP using Sigtran techniques High Availability infrastructure to support VoIP; PTT launching now
! Wireless data services picking up
Recent growth driven by new terminals & applications
Required to counter declining voice ARPU and competition
AIS launching 40 new data applications this year as part of an objective to
double non-voice revenues CEO Somprasong Boonyachai
! Access costs still major opex factor looking at means to optimise
! Increasing corporate market for mobile data
! Lots of Hype on WiMAX

WiMAX Sowhat is it?
! New set of efficient radio technologies enablingbroadband connectivity over wireless
!Fixed and mobile variants
! Promoted heavily by Intel growing industrysupport
! Designed to operate in both licensed ANDunlicensed spectrum key difference
! Just access technology still needs IP subscriber

Summary What to look for in 2005
! WiMAX for fixed line alternativewill go into trials and early deployments
Valid niche little or no overlap with 3G
! WiMAX mobile broadbandis still 2-3 years away
Industry will look to Korea as test, device availability and costs key
! 3G operators accelerate their move to new packet architectures
Drivers new services, reduced costs, voice & signaling move to IP
IPv6, High Availability and ATM over MPLS are key
Technology now proven successful deployments today
! Continued value add to corporate space eg SSL VPN
! IP Router manufacturers like Juniper are active and key players in new mobile
infrastructure
