Wireless technology provider Nomad Digital will unveil a new technology at Innotrans next week in Berlin, Germany, to improve internet speeds onboard trains, buses and trams.

Nomad Charger will offer a web user experience that is around two to three times faster with reduced timeouts and fewer lost connections, according to Nomad.

Nomad Charger will optimise the use of available bandwidth, whether it is available through satellite or mobile networks, by improving the main communication protocols and sharing the flow of information, which helps in offsetting network delays or latency time, creating bottlenecks in web browsing.

Nomad Digital chief executive Alexander Eriksen said that rail companies can currently either add more modems or network capacity to get increased bandwidth and internet speeds.

"But this is a much more costly approach compared to simply adding software that gives you the best performance from what's already out there," Eriksen said.

"Nomad Charger will offer a web user experience that is around two to three times faster with reduced timeouts and fewer lost connections."

"[Nomad] Charger allows internet onboard to operate more smoothly and make better use of available connectivity, especially in view of the inherent challenges of network disruptions on many train, tram and bus routes around the world."

Nomad Charger has been tested on several trains, buses and street cars that showed four to five times faster download speeds when performing priority operational downloads, such as live or recorded CCTV video.

The company said that the new technology can achieve around 13 times higher download speeds when network interruptions occur, such as those experienced in tunnels.
