Competition between Luxembourg’s wireless carriers picked up speed this week, with the launch of a big upgrade to one operator’s 4G mobile network.

4G stands for the “fourth generation” of global mobile telecommunications standards, and is meant to deliver data download speeds that are more or less comparable to a fixed line internet connection. It was first rolled out in the Nordic region in 2009 and in the Grand Duchy last year.

The previous system, 3G, was widely introduced across the world starting more than a decade ago.

Tango said on its website that 4G download speed is roughly ten times faster than 3G. The mobile operator said in an announcement on Monday that its new system, with the brand name “4G+”, can be 50% zippier than that.

“4G+ delivers an experience comparable to optical fiber for fixed internet connections,” with download speeds increasing from the current upper limit of 150 Mbps to “as high as 225 Mbps,” the firm stated.

Theoretically that means a 45 minute HDTV show could be downloaded in less than 2 minutes, based on figures published by Apple.

Average network speeds are, of course, lower than the maximum figures advertised, depending on location and the number of other users on the same network.

According to the telecom firm, the “cities of Luxembourg, Esch-sur-Alzette, Differdange, Schifflange, Bertrange and Rodange are the first to benefit from Tango’s 4G+ network coverage. The roll-out plan will continue in 2015 in order to extend the power of the 4G+ network quickly to the whole of the country.”

In addition the company stated that “4G+ will be available to all Tango customers with a 4G-inclusive subscription over the course of the first quarter of 2015, at no additional cost.”

Rival carriers Orange, Post and Join Experience also provide 4G service.

Last week GSMA, the international mobile operators trade association, forecast that the number of 4G connections in Europe would rise from less than 10% of mobile subscribers this month to more than half by 2020.
