Data transfer has always been a matter of concern for cellular phone users. The existing modes of data transfer are not very user friendly, as they have to either be in eye-to-eye contact or have to be very close to the target downloader. Enabling WLAN interface in the handset not only reduces the cost of call but also helps the user to make cellular calls when moving and make VOIP calls when stationary. To enable VOIP calls or even to overcome the lower data transfer a different underlying interface has to be defined. Providing WLAN interface in the handset will serve these two purposes.
IPv6 or 'Internet Protocol Version 6' is the next generation protocol designed by the IETF to replace the current version Internet Protocol, IP Version 4 (IPv4). Most of today's Internet uses IPv4, which is almost twenty years old. IPv4 has been remarkably resilient in spite of its age, but it is beginning to have problems. Moreover, there is a growing shortage of IPv4 addresses, which are required by all new machines added to the Internet. IPv6 overcomes a number of problems in IPv4, such as the limited availability of IPv4 addresses. It also provides improvements in areas such as routing and network autoconfiguration. IPv6 is expected to gradually replace IPv4, with the two coexisting for a number of years during a transition period.
