Rosum Corporation, a provider of location and timing solutions for broadcast TV infrastructures, has successfully completed a DVB-H positioning trial in collaboration with National Grid Wireless, the UK's leading provider of large-scale transmission infrastructure.

The companies conducted the trial at National Grid Wireless' DVB-H trial network in Warwick and utilised DVB-H mobile TV broadcasts to locate precisely prototype receivers in a variety of environments, including multi-storey car parks where GPS-based solutions are unavailable.

The companies say that they successfully demonstrated that the same signals used to deliver mobile TV content can be used to provide position-based services.

Commented Skip Speaks, Rosum CEO, "We are pleased to announce the successful completion of our DVB-H positioning trial in collaboration with National Grid Wireless. Use of DVB-H broadcast networks for position-based services could provide an additional revenue stream for network operators, in addition to enhancing the subscriber experience."

Rosum has specialised in developing, patented and fielded location and timing solutions harnessing the broadcast TV infrastructure that are effective where GPS is most challenged. Such environments include indoors and urban canyons.
