Advanced Wireless Data Communications


Information transfer is playing an increasingly important role in many different aspect of transportation. Passengers are demanding increased visibility of arrival and departure times for all forms of transport and the transport operators are looking for more efficient methods of data collection and network control.

Wireless systems are an obvious solution for communicating to or from moving vehicles, vessels and aircraft and are also often the best solution for supporting large or small infrastructure links, as it avoids the disruptive work involved in running data cables between locations.

Our products are used extensively within flight information & data systems (FIDs) for transmission of flight departure/arrival data to remote display screens, which can be located in; airport terminals, baggage handling areas, airport vehicles, bus stations, car parks and off-site hotels. As no connecting data cables are required, it is very easy to locate terminals almost anywhere, even on a temporary basis.

Radio links can also be used for traffic light control and for remote sign control on road networks. Signs can be easily controlled either from a central site or from a local roadside detector, either on a permanent or temporary basis.

On the railways, custom designed radio modules are supplied by RF DataTech for use in track side alarm and safety systems, inter-carriage communication for coupling and de-coupling and portable controllers for the remote control of freight trains in shunting yards at distances of up to 1km. These bespoke RF modules were specifically designed to meet the clients demanding requirements for radios with exceptionally fast response times, high receiver sensitivity and excellent interference rejection to allow safe and reliable operation in such a critical environment.

RF DataTech radios are also being used in marine environments for the transmission of differential GPS (DGPS) position corrections from a fixed, well defined reference location on the shore to nearby survey vessels or dredgers to allow extremely accurate position determination.
