Mobile phone operator T-Mobile is claiming to have setup the world’s first multi-user 4G / LTE test network in Innsbruck, Austria.

The test network, thought to be the largest in Europe, uses sixty cell phone towers and has been running since July. The company is using its existing 3G phone service as the technical base for the tests.

T-Mobile is trialling the 4G phone service to put the technology through its paces and to gain user feedback.

Austria has one of the highest rates of mobile data usage in Europe. One third of revenue generated by Mobilkom Austria – the Austrian market leader – comes from mobile broadband services.
