Mobile network could cause train delays

New mobile network technology being introduced in Sweden could interfere with communications between trains and cause stoppages and delays.

The Swedish mobile network has been strengthened in order to make it more possible for train passengers to surf while riding. But the technology might interfere with the Transportation Authorities own mobile network and could lead to train stoppages, according to newspaper Dagens Nyheter.

Telecommunications companies Tele2 and Telenor have spent hundreds of millions of krona on 230 new base stations in their joint 4G network, which is intended to give better reception in trains. The Transportation Authority has protested because the new frequencies can interfere with their own.

A decision was reached in courts in 2011, saying that the Transportation Authority had until 1 July 2015 to come to terms with the mobile network changes, at which point the mobile operators would be free to fully activate the technology. But the Transportation Authority is requesting an extension to this deadline.

Thomas Ekman, CEO of Tele2 Sweden, told Dagens Nyheter that they are irritated because the Transportation Authority already has had several years to solve the problem.
