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

management to control and deliver services

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
