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

Ⅱ. Technology Overview

Seamless Mobility

Fast & Secure Handover

Chantry networks’ (acquired by Siemens) virtual network service

Meru networks’ patent-pending, ‘Meru Air Traffic Control Technology’

Seamless Roaming

- Avaya,Motorola and Proxim have collaborated to provide a proprietary

roaming solution for Motorola CN620 dual mode deviceSCCNA

- Offers a hosted dual mode solution, ‘One phone,’ being tested by at least one operator in Europe

LongBoard

- Provide interoperability testing, aim to help deliver end-to-end dual

mode systems to carriers.Mobile IGNITE

- Define network elements and protocols that support user authentication

and the transparent handoff of calls based on both Wi-Fi and Bluetooth
