View source for 9. What kinds of Business Models(Service Package) will be possible?

- What kind of services do the existing Wireless Service provide? 

Wire Broadband case (like DSL) in Korea, "the Cable TV Service + Broadband Cable + PSTN phone package" is popular. "Wiless Broadband; Wibro" is conceptually new service. So I believe that "Wibro + VoIP + DMB (if DMB supported with terminal)" could be attractive. And Wibro is drived by telecom companies; SKTelecom and KT. So providing services pacakage could be a good approach for KT and SKT because Wibro and their services (Mobiel, PSTN, DSL services) will compete each other.

* WiBro is NOT designed for voice service only!

- The existing mobile systems are evolved from voice-only service.

- VoIP service will hurt the overall efficiency of WiBro simply due to enormous overhead

* Enhancement of WiBro for VoIP service?

- To include some means of fixed periodic bandwidth assignment just as in the legacy mobile system

- To increase he overall system capacity, e.g., using the smart antenna & MIMO
 
- To employ an effective scheduling algorithm for integrated services
