Ericsson and A1 Telekom launch 2x20 MHz carrier aggregation

Carrier aggregation doubles peak downlink data rates in A1 network up to 300 Mbps and double median throughput

Ericsson and A1 Telekom launch 2x20 MHz carrier aggregation

Ericsson has provided A1 Telekom Austria, the largest operator in the country, with Austria’s first commercially launched 2x20 MHz carrier aggregation system for 800 MHz and 2.6 GHz.

A1 Telekom has deployed the service in the city of Graz and plans to increase the footprint for 800MHz/2.6 GHz CA by rolling out to other cities during 2015. Users will enjoy download speeds of up to 300Mbps on the A1 Telekom LTE network.

Carrier aggregation is a crucial component for the evolution of LTE Advanced. By means of this specific 800MHz and 2.6GHz carrier aggregation, peak and median downlink data rates and capacity will be increased, so that more people can use high-speed internet.

This will significantly improve indoor coverage, as well as consumer services such as video and enterprise applications, accelerating downloads, improving video streams and optimizing app performance for users.

The operator’s LTE network currently covers 60 percent of the Austrian population. As one of the first European operators A1 Telekom Austria is deploying LTE on 800MHz frequencies both to provide remote rural areas with broadband, and also complementing 2.6GHz LTE to improve indoor coverage in urban areas.

Thanks to the 6-cell support functionality, a typical combined mobile site can provide 3 cells with 800MHz, while 3 more cells transmit on the 2.6GHz frequency band.

Marcus Grausam, CTO A1, commented: “The performance enhancements that are achieved by LTE carrier aggregation allows us to provide our customers with twice the median and twice the peak data rates compared today while at the same time significantly improving application coverage in areas that are difficult to cover such as indoors.”

Valter D’Avino, Head of Ericsson Region Western & Central Europe, said: “This is an important step in the evolution of today’s mobile networks towards LTE Advanced. The peak data rates in A1 network climb up to 300 Mbit/s and in the future with LTE Advanced up to 1 Gbit/s in a cell will be possible.”

LTE carrier aggregation continues to increase in importance to operators as a means to make more efficient use of spectrum holdings and to deliver better app coverage with higher peak data rates and better cell edge performance.
