Unifying NBN fibre and wireless networks

Singapore Telecommunications (SingTel) has announced it a trial of Long Term Evolution (LTE) mobile wireless technology in Australia with Optus during 2010. LTE offers up to 340 Mbps, but more significantly should make it easier to integrate with other wireless and wired broadband networks, such as the National Broadband Network. LTE is claimed to be compatible with WiMax broadband wireless, which the Australian government is funding to fill in some urban broadband black spots. LTE uses IPV6 and this could make it easier to provide services across networks without ad-hoc arrangements for levels of service and security. By using the network more effectivly, this might reate a better and cheaper service than by simply adding more bandwith. LTE also has an option for providing TV like services. What is not clear is if it can be adapted to the needs of regional Australia, with a low population density. It may be that CSIRO's "broadband to the bush" could be combined with LTE.
