Swedish vendor Ericsson and Bombardier completed trials of LTE networks for railway solutions at simulated speeds of up to 200 kilometers per hour.

A total of 11 tests were conducted in a laboratory to determine the ability of the LTE networks to support communications-based train control (CBTC) and multiservice solutions such as closed-circuit television (CCTV), voice, platform information, advertising and Wi-Fi for passengers.

CBTC uses high-resolution location determination and high-capacity data communications – such as those enabled by LTE networks – to support automatic train protection, operation and supervision functions.

In the CBTC tests, the LTE networks achieved uplink and downlink latencies far below the threshold of 100 milliseconds and packet loss approaching zero, Ericsson said.

“The results of the tests performed to date are very promising and we will continue to test a variety of modems to ensure we can provide robust LTE networks for rail applications. We aim to develop solutions that ensure enhanced rail safety through communications-based train control and CCTV, as well as enhanced entertainment for passengers through services such as voice, platform information, advertising and Wi-Fi,” Ericsson’s head of Customer Group Industry & Society Charlotta Sund said.

In other EMEA news, German telco Deutsche Telekom has achieved mobile Internet speeds of up to 1.2 Gbps during an LTE-Advanced Pro demo in Poland’s capital Warsaw.

The test was carried out by T-Mobile Polska, together with Nokia’s R&D Center in Wrocław. The two companies aggregated four carriers on 1800 MHz, 2100 MHz and 2.6 GHz bands together with 4×4 MIMO technology.

“We already demonstrated our innovative strength in mobile networks in 2010 with Germany’s first commercial 4G LTE radio tower in the town of Kyritz an der Knatter. Today, we are instrumental in driving the development of 5G through our involvement in NGMN,” said Bruno Jacobfeuerborn, Chief Technology Officer at Deutsche Telekom.

“Deutsche Telekom is, of course, not missing out the step in between. In Poland, we’ve now been able to show what’s possible on the basis of LTE technology and the direction development may take.”
