Major Issues of Technology
Extending battery life
Using multi-media services with mobile services free of battery life
Quality of Service (QoS)
QoS standards : WCDMA, 802.11a/b/g, 802.11e, broadband network
- Supporting without packet delay, loss, …
- Internetworking between wired and wireless network
Security
Protecting data whenever roaming & handover between different devices & networks
Wireless infrastructure
WCDMA, WiBro(2.3G), WiMax, WiFi extending service coverage
Fast & secure handover
A session is transparently switched to the new point, minimizing the signal delay.
Seamless roaming
Supporting user authentication and the transparent handoff
Providing interoperability of different networks
e.g) UMA, SCCAN, MobileIGNITE
