WLAN Ericsson, BT Wireless, and SmarTone in Hong Kong staged the world's first successful end-to-end demonstration of IPv6 - the next-generation Internet Protocol - in a mobile network. The SmarTone trial was built on Ericsson's network-enabling IPv6 systems and know-how, in conjunction with BT Wireless' research and development activities. Ericsson has a long-term cooperative relationship with SmarTone in the Hong Kong operator's infrastructure development.

We also tested other scenarios, such as roaming between fixed and wireless networks, and IPv4/IPv6 interworking - all successfully. IPv6, with its 128-bit address base, will provide address space enough to accommodate an IP address for every imaginable Internet-ready device to come. IPv6 enables network architects to address many important IP-related issues in addition to the IP address shortage, such as security, quality of service, mobility, multicasting, and network management. Ulf Ewaldsson, Deputy Managing Director of Ericsson in Hong Kong, says, "IPv6 will enable a new level of end-to-end IP-based services and applications. It is an important part of the Ericsson vision, with billions of devices that are constantly on-line, providing the user with an uninterrupted, personalized and location-independent experience." SmarTone's Chief Technical Officer, Stephen Chau, says, "It is crucial that we begin trialing IPv6 on our network as soon as possible, so that we can gain solid knowledge and insight into the potential it brings to the development of mobile Internet applications and services."
