4GE LTE Modems for Intelligent Systems

Västtrafik in Sweden is responsible for the public transport in all of Västra Götaland. They have 2,700 buses, trains, trams and ferries as well as 22000 stop locations.

All vehicles combined will be driven 390,000km on average every day. This makes Västtrafik the second largest public transport company in Sweden. They also organize the transport, compile the timetables and decide upon routes and lines.

BUSINESS CHALLENGE:
There were legacy IT systems installed in every bus, train, tram and ferry to connect with passenger information system, driver safety system etc., and a GPRS modem was used for network connection. However, during years of running, Västtrafik was experiencing problems with narrow band and unstable GPRS connection, especially in rural areas. Due to these issues, the Swedish operators were also considering leaving the GSM/GPRS network for M2M communications.

Västtrafik realized that in order to achieve reliable, consistent 3G/4G LTE connectivity, they would need to upgrade to a more ruggedised modem. So they decided to choose a modern path with 3G/4G LTE compatible hardware and also sign a service contract with TELE2, one of the largest operators in M2M.

Because of 3G/4G LTE’s instant handover time, high bandwidth, they could maximize the network availability, and provide seamless communication for in-vehicle IT systems for the future.

SOLUTION:
4G LTE Robustel M1000
The LTE modem is used not only in the buses but also trams, trains and ferries across the country.   Each application has to undergo appropriate certifications to meet all the fireproofing and railway standards regulation demands.

Västtrafik tested solutions from several leading vendors and finally selected Robustel M1000-U4L LTE modem because of its sturdiness, network compatibility, and seamless connectivity performance during the trial.
