Nokia and Telefónica Germany have completed building their joint “Early 5G Innovation Cluster” in Berlin. The “Early 5G Innovation Cluster” incorporates five sites in Telefónica’s cellular network in Berlin-Friedrichshain. These sites, equipped with Nokia 5G Airscale radio and Wavence Microwave technology, will be used in the next months primarily to test and measure the performance and coverage of first 5G services in a dense urban area.
A clear rating improvement and a rise of an impressive 127 points in the 2018 connect network test serve as confirmation that Telefónica Deutschland has massively improved the quality of its O2 network throughout Germany this year. This leap forward for the O2 network would have been even more substantial without the more stringent measurement criteria applied this year. The company is the only German operator to have improved its result. Thanks to extensive quality improvements, the O2 network significantly reduced the gap to the competitors in this year’s network test. It recently received a “good” rating in the network test by specialist magazine CHIP, which described the O2 network as having made a “quantum leap”. The continued expansion of the network is already in full swing.
A clear “good” rating for the O2 network, leaping up almost an entire point in comparison to the previous year (from 3.1 to 2.2): The results of the current, Germany-wide CHIP network test clearly show that Telefónica Deutschland has made huge improvements to network quality for its customers thanks to its extensive network measures. The specialist magazine CHIP even referred to it as a “quantum leap”. The O2 network was also rated as good to very good in the sub-categories Internet, voice and LTE network as well as in multiple major cities. At the same time, Telefónica Deutschland announced more improvements to network quality in the year to come.
Telefónica Deutschland successfully moved ahead with the modernisation and expansion of its O2 mobile network in 2018. The network integration of O2 and E-Plus has made particularly good progress, with network quality improving in many areas. This has been confirmed by current measurements from network testing specialist P3 for major cities such as Cologne and Leipzig. Customers in increasing numbers of cities and regions can now benefit from a new and improved O2 network thanks to the network integration, which is now in its final stages across all of Germany.
Telefónica Deutschland is having more than 1,500 mobile base stations connected to GasLINE’s high-performance network infrastructure in order to prepare it for the future technology 5G and for new digital applications. The two companies have already been cooperating successfully for several years on fibre-optic connections for mobile base stations and in the backbone field, and they have now signed a contract for another extensive expansion programme.
Telefónica Deutschland is consistently continuing the comprehensive expansion of its LTE network. In the third quarter of 2018 alone, Telefónica Deutschland installed nearly 2,000 new LTE stations and upgraded existing locations with additional LTE capacities. In total, the O2 network has already been expanded by around 5,000 LTE stations this year. By way of comparison, the area newly supplied with LTE is significantly larger than the federal state of Hesse. The company is thus fulfilling its announcement not only to further densify its LTE network in cities, but also to rapidly expand its LTE network in rural areas so that more and more customers can surf the O2 network in more and more locations at faster speeds.
Deutsche Telekom and Telefónica Deutschland are joining forces to accelerate the expansion of their mobile networks. The two companies have agreed to connect at least 5,000 Telefónica Deutschland mobile network sites in total to Telekom’s high-performance fibre-optic infrastructure in the long term. In turn, Deutsche Telekom can directly leverage the synergy effects from this to expand its own network. This cooperation is not just remarkable because of its size. It is also ground-breaking in terms of the future 5G communication standard and new digital applications.
Telefónica Deutschland has successfully implemented the voice standard Enhanced Voice Services (EVS) within its national LTE network. Technically speaking, the new voice standard is a further development of AMR-WB (Adaptive Multi-Rate Wideband): O2 customers in the LTE network can now make calls in excellent Full HD voice quality. With EVS, telephone calls are transmitted much more clearly and naturally than before – EVS transmits the audible frequency range at up to 16,000 Hertz instead of up to 7,000 Hertz as used to be the case. As a result, EVS means conversations are perceived as clearer, more understandable and therefore more natural. Another advantage is that the new codec allows background noise to be suppressed better than before. EVS significantly improves the sound image compared to previous mobile calls.
No other network operator is better than O2 when it comes to providing customers in Munich with LTE - this is the result of a recent network test for mobile communications coverage in the Bavarian state capital by specialist magazine connect. Overall, the new O2 network in Munich achieved a “good” rating (830 points), having significantly improved in terms of network quality compared to the last nationwide network test in 2017 (result “sufficient”).
Telefónica Deutschland is currently pushing the nationwide LTE expansion on a massive scale. In order to enhance its customers’ network experience, the company is constructing several new LTE stations in both urban and rural areas and increasing existing capacities. In the first half of 2018, the telecommunications provider already installed more than 3,000 additional LTE stations or upgraded existing LTE sites. This corresponds to approx. 120 LTE upgrades per week – at peak times even 200 per week. Thanks to this comprehensive network expansion, even more customers can browse the web at high speed in more and more places, stream videos smoothly, share their pictures with other people within seconds and make calls in the best HD voice quality thanks to voice telephony via LTE (Voice over LTE; VoLTE).
On its way to the mobile communications network of the future, Telefónica Deutschland is cooperating with NGN FIBER NETWORK KG (NGN) from Lower Franconia in order to have parts of its mobile communications locations connected to high-speed fibre-optic lines. The goal of the network operator is to further improve the performance of its own LTE network, while laying the foundation for a nationwide 5G network that offers significantly better data rates, higher capacities and extremely low latency times.
In addition to existing projects such as TechCity and "5G Connected Mobility", Telefónica Germany has been supporting another 5G project since the beginning of the year. At the transmitter site in Wendelstein near Rosenheim, a test field for 5G broadcasting in the frequency range around 700 MHz is currently being built.
Telefónica Deutschland will be the first network operator in Germany to provide voice calls via LTE and WiFi for all customers of its home brands and partner brands. This includes both postpaid and prepaid customers. When making calls with these technologies, so-called “Voice over LTE (VoLTE)” and “Voice over WiFi (VoWiFi),” customers benefit from improved voice quality and expanded network coverage via LTE and WiFi at no additional cost. Telefónica Deutschland will gradually implement the services across the individual brands and customer groups, and plans to have completed the process by the end of March 2018.
