Telekom Austria and Nokia demonstrate 850 Mbit/s LTE data rate in Slovenia

Telekom Austria Group has announced further progress towards its goal of implementing 5G mobile technology by 2020 via a demonstration by its subsidiary A1 Slovenija in Slovenia, Central Europe, which has demonstrated data transfer rates of up to 850 Mbit/s over what it believes is the fastest live LTE network currently operating in Europe.

The latest test was conducted in partnership with Nokia at the premises of A1 Slovenija in Ljubljana, where a maximum speed of 877.5 Mbit/s was achieved over the Slovenian A1 LTE network. The data rate was enabled through the implementation of multi-component downlink carrier aggregation functionality in the downlink.

To achieve the downlink throughput in a live network, rather than in a lab setting, a total of 55 MHz of the Slovenian A1 frequency spectrum was used, with 35 MHz on band 7 (2,600 MHz) and 20 MHz on band 3 (1,800 MHz). The frequency band 7 was additionally supported with 4 x 4 MIMO in the downlink, while 256QAM modulation coding was implemented on both frequencies, increasing the maximum peak data rate by an further 30%.

Telekom Austria stated that the enhanced utilisation of frequency spectrum in the A1 LTE network was achieved in cooperation with Nokia, its technology partner. As the next step toward delivering 5G, Telekom Austria Group has stated that it is aiming to increase the peak data rates at its subsidiaries by implementing further technical innovations such as massive MIMO, beam forming and beam steering.

Commenting on the latest test, Peter Wukowits, country senior officer and head of Central Europe at Nokia, said, "With this 4.5G Pro demonstration, utilizing Nokia's 5G-ready AirScale platform, Nokia and A1 Slovenija reached a milestone towards 5G... speeds above 850 Mbit/s are approaching a gigabit society, where mobile networks will provide fibre-like speeds close to 1 Gbit/s".



  • In December 2016, A1 and Nokia announced that as part of the move towards 5G they had achieved a data rate of 513 Mbit/s over the A1 live network on a mobile router and 463 Mbit/s on a smartphone at Austria's University of Klagenfurt. The trial involved 3 carrier aggregation with frequencies in the 2,600 MHz, 1,800 MHz and 800 MHz ranges, plus 256QAM modulation.
  • Recently, also working with Nokia, Telekom Austria Group subsidiary A1, which serves the Austrian market, announced a demonstration carried out in the city of Vienna during which transmission rates of more than 10 Gbit/s were achieved over installed copper cable in its fixed line network.
  • The fixed network transmission speed achieved with Nokia leveraged an advance in the existing copper-based G.fast technology, XG-FAST. The test specifically involved 30 metres of copper cable and test equipment supplied by Nokia Bell Labs, and demonstrated that the existing copper cables between the street or basement of a building to houses or apartments can potentially support speeds in excess of 10 Gbit/s.

Telekom Austria's Serbian Subsidiary Demos vEPC with Connectem and Partners

Telekom Austria Group’s Serbian subsidiary, Vip mobile, demonstrated a fully virtualized LTE stack in a live network delivering data, voice and IMS services.

Connectem provided the virtual Evolved Packet Core (vEPC). Metaswitch provided its virtualized Clearwater IMS Solution and OpenCloud provided the virtualized VoLTE functionality.

Connectem’s Vip mobile Ecosystem Partners include:

VMware -- Connectem and VMware collaborated to bring VMware vSphere to the VCM solution.  Telekom Austria Group undertook numerous tests to experience the resilience of Connectem VCM across VMware vSphere to understand the long-term implications of running a vEPC in a virtualized infrastructure.

Procera -- Within the Connectem VCM, essential DPI functionality enabling application detection and content optimization is provided by Procera’s NAVL DPI engine. Procera’s software-based DPI technology is well suited to fit within the scalable dataplane of the VCM.  Procera NAVL allows Connectem to integrate this vital traffic treatment function without the performance degradation typically generated by traditional DPI solutions.

Red Hat -- The combination of Red Hat Enterprise Linux, including the Kernel-based Virtual Machine (KVM) hypervisor, and Connectem’s Virtual Core for Mobile (VCM) creates an NFV environment providing a high-performance, cost-effective OpenStack managed NFV implementation that can help to increase infrastructure flexibility and that can be scaled up or down to accommodate the needs of the network.

Guenther Ottendorfer, CTO Telekom Austria Group, said, “NFV is a paradigm shift for the global Telecom industry but also shows that there are many innovations on the horizon which will further enhance the customer’s experience and the operator’s ability to meet the customer’s changing expectations. NFV signals a new optimism within our industry, with the potential of offering huge opportunities to reengineer and optimize network infrastructure and deliver better service for our customers.”

Telekom Austria Adds EUR 400M to Broadband Rollout

Telekom Austria announced additional investments of up to EUR 400 million for its ongoing broadband rollout in Austria.

"Following the successful conclusion of the capital increase of EUR 1 billion, trading of the new shares on the Vienna Stock Exchange commenced as of today. Our next important item on the agenda with regard to the allocation of the new funds mainly concerns investments in our core markets. In our domestic market, Austria, given the right framework conditions, additional investments of up to EUR 400 million will boost broadband rollout. In this way, we are equipping the country with the necessary infrastructure to meet the challenges lying ahead in the 21st century, while setting important impulses for economic growth and job creation," said Hannes Ametsreiter, CEO Telekom Austria Group and A1.

Telekom Austria also said the infusion of cash will give it the option to pursue strategic acquisitions, inline with the following priorities: (i) in-market consolidation to strengthen existing operations; (ii) the continued pursuit of Telekom Austria Group's convergence strategy to diversify in markets that are currently mobile-only as well as to enhance existing convergent operations; and (iii) expansion via new operations.
