The future requirements for communications within the transport sector

摘要

We have found that increased spectrum usage within transport is most likely to occur in four areas, one of which is likely to require new spectrum over the next 10 to 20 years. However the requirements are on the whole quite modest and many could be absorbed within present or planned communications systems, for example existing cellular deployments or other public wide area networks expected to appear at 2.6GHz. We have noted that the introduction of communications technology into the transport sector can be slow, although technology appears not to be the limiting factor. We conclude that substantial interaction and investment is needed between multiple manufacturers and owners of transport infrastructure on a world-wide basis and that it remains far from clear who could lead this initiative.
