High-Speed at High-Speed (HaH)
LTE for Vehicle Applications and Railways
We offer advanced LTE for vehicle applications and high-speed trains.
Introduction
The leading-edge Long term evolution-advanced (LTE-A) system, which is one of the two candidates for the fourth generation cellular systems (4G) developed by 3GPP (another is Mobile WiMax, the IEEE 802.16m), is probability the most complex commercial radio that has been proposed and being developed in history of information industry featuring in Gigabit data rate, low latency, support for high-mobility and world-wide roaming, compatibility with legend LTE, high spectrum efficiency, better coverage at cell edge and many others. The main technical merits of LTE-A is to adopt two dimensional, in both the frequency and the time domains, parallel transmission technologies, known as orthogonal frequency-division multiplexing (OFDM) and multiple input multiple output (MIMO), respectively, Currently, LTE-A updates with the latest version of Release 10 of 3GPP specifications and is estimated to be formalized in March 2011. In fact, the research and development of LTE-A has been extensively performed worldwide ranging from theoretical study, simulations and prototyping. The leading in the competition of LTE-A among nations reveals, in a certain degree, the gradation of its scientific potential of a nation. It is not surprised that we have witnessed the fierceness of competition and the persistence supports from Governments in many countries worldwide. The development of LTE-A would be a high risk high gain game and will take a plenty of engineer years to complete. Moreover, the success of the LTE-A counts on many imperative elements including policy and regulations, financial investment and market growth, except technology itself. Currently, LTE-A is still in its infant stage worldwide. A lot of companies and institutes start to build up functional prototypes but, actually, most of them are still in proof-of-conception stage and laboratory development phase. Unfortunately, none of them has been specifically designed for vehicle applications and high-speed trains, while we do.
