Hiya Nokia Siemens Networks and LG Electronics have achieved an LTE downlink data transfer rate of 100 Mbps, the maximum speed for a Class 3 LTE terminal. In LTE, user equipment is categorized into classes based on its potential uplink and downlink data rates. Class 3 terminals are expected to be the first widely used commercial LTE terminals when they are launched later in 2010. This data call, operating a Class 3 terminal at its 100Mbps limit, therefore demonstrates significant progress towards commercial LTE.
Wi-max is working already on 150 migs in Tokyo, London, Stanford and Hongkong, Which is already a loads of bandwidth. Although, there are plenty of claims of switching over to 4G in some first world countries - theoritacally, if not practically. Its all about marketing, generating revenues and Operators will take advantage of this market opportunity by breaking down their walls and building open ecosystems. According to ABI Research practice director Philip Solis, “Operators of 4G networks will refuse to be marginalized as ‘dumb data pipe’ service providers. Instead, they will offer suites of ‘smart services’ – some internally developed, others via partnerships with third party suppliers – that will be provided over ‘smart networks’ enabled with all-IP technologies, IMS infrastructure and cloud-based storage. As I said earlier 150 migs for corporate world in first world countries is really a lot, which is entirely based on 3G. Assuming India skips 3G for 4G. I wonder, how much time and cost, operators need to shell out to change the whole infrastructure from the scratch. Whilst they're working hard even to make MNP compatible with their current infrastructure. Cheers - KG On 25/02/2010, Subramani L <[email protected]> wrote: > No one could define clearly what is 4G.
