Standard Problem
• No global 450MHz band allocation in ITU
• Standardization of roaming and service interworking– Roaming
• CDMA networks of different frequency band• CDMA/GSM system
– Service interworking• CDMA/WCDMA/GSM/WLAN

PTT Service
• Individual– Families, Friends, Teenagers, Leisure groups like
sports, outdoor activities
• Corporate– Private entrepreneurs
• Professional– Service and repair, Retail, distribution,Taxi, limousine
service, Utilities, gas, energy
11
PTT Forecast
• Existing services are Nextel(iDEN) in US– 13 Million subsriber, 96% of PTT service– Highest ARPU in US market– Effectively “owns” the enterprise segment

Next Step in PTT
• Interoperability– Interworking of Different Systems– Interworking of Different Solutions
• Performance vs. Cost– To Improve Efficiency in Air Interface– To Improve Performance
• Access Speed• QoS of Voice
OMA will release first PoC specification in Q4, 2004
14
Broadband Access Application
• Launch 1xEV-DO service with the brand “June”• “June” services: Video Phone, MOD, VOD, Multimedia Information• Video Phone service now has 15K subs, and SKT plans to develop to
400K• “June” subs has 3 times data ARPU (12$) as that of 1X subs(4$)• 450MHz Do can be used to substitute xDSL in rural market

Next Step in Broadband Access
• Broadband Access– Many technologies appear in the market– WLAN-3GPP2 interworking is in progress– Security is an important issue
• 1X EV-DO– No standard work on video phone service– Dual mode 1X & DO terminal problem
• Concurrent service (voice + data)• Power consumption
– Several application platforms, interworking of differentplatforms is still open
18
BCMCS Application
• Infotainment on demand– News– Sports– Living style information– Entertainment information
• Music on demand• Video clip
– Cartoon, MTV, moviepresentation, TV programforecast
• Live TV• Video advertisement
Next popular and profitable service: Live pocket TV
