BANGKOK - Nokia (NYSE: NOK) today demonstrated the world's first dual stack IPv4/IPv6 CDMA handset, setting the standard for future mobile Internet devices. This prototype handset addresses the increasing demand for advanced Internet-connected mobile devices in an environment in which existing Internet Protocol version 4 (IPv4) addresses are rapidly being depleted, and will soon be replaced by nearly infinite Internet Protocol version 6 (IPv6) addresses. Nokia is currently offering prototype IPv6 CDMA handsets to operators for testing purposes, and will be ready for commercial delivery of dual stack IPv4/IPv6 handsets during 2004.
First standardized in 1981, IPv4 has served as the basis of the Internet as it has exploded over the past two decades. However, this very success has stretched the IPv4 standard to its limit, and the growth in Internet-connected mobile devices and emerging Internet markets, especially those in the Asia-Pacific region, is necessitating a change in standards. Interim solutions like network address translation (NAT) that are currently being implemented work reasonably well for fixed devices, but create additional problems for mobile devices. IPv6 is the long-term solution for the issue of limited IPv4 addresses for all types of connected Internet devices.
"Nokia recognizes the pressing need for IPv6 technology in advanced mobile devices and networks, and is leading the industry in making it a reality," said Adam Gould, vice president of technology management and strategy for Nokia's CDMA business unit. "Our work in both the 3GPP and the 3GPP2 will shape the mobile Internet, and help insure the successful adoption of advanced wireless applications in the future."
Besides the obvious increase in address space that it provides, IPv6 also provides additional security benefits to users. IPv6 includes packet encryption and source authentications for end-to-end security protection, and a "flow label" to support real-time traffic in a mobile environment. IPv6, by providing unique and globally routable IP addresses to users, enables a new generation of peer-to-peer applications and push-based services.
The introduction of dual stack IPv4/IPv6 devices is essential for the seamless transition of current IPv4 based networks and devices to the upcoming IPv6 environment. This approach allows for interoperability between IPv4 and IPv6 systems, allowing service providers to offer advanced services during the transition to IPv6. Additionally, using this approach allows operators to adopt a more gradual transition from IPv4 to IPv6, creating less pressure on existing networks and resources.
