According to foreign media reports, Deutsche Telekom claims that it has conducted its first European 5G connection on a commercial network in Germany in a technology demonstration that is predicting the nature of the company's next-generation mobile broadband program beyond 2020. Deutsche Telekom said it has teamed up with Chinese equipment maker Huawei to conduct a 5G connection demonstration on its network in central Berlin via the 3.7GHz spectrum, with a delay of more than 2 Gbit / s and a delay of only 3 milliseconds. In terms of connection speed and latency (the delay that occurs when sending signals over the data network), the company's data easily beat current state-of-the-art 4G networks - which are struggling to deliver gigabit speeds. However, Deutsche Telekom is unlikely to promise its commercial 5G network that all of its customers have access to at this mobile broadband speed. Of course, Deutsche Telekom and Huawei relied on so-called "quasi-5G" systems for this demonstration of technology in Berlin without the introduction of a true 5G standard so far. The technology used depends very much on the 5G new radio (NR ) Specification (3GPP plans to end the specification by the end of 2017). The standard setter decided earlier this year that it would take six months to terminate the 5G NR specification. The decision means that equipment vendors such as Huawei will need to start standardizing 5G equipment sooner than expected, and carriers will start earning standards-based 5G services as early as 2019. As Deutsche Telekom explained in its Berlin presentation, this "first" standard is called "Non-Independent" (NSA) 5G and will combine the use of 5G NR with existing 4G networks. This approach will allow Deutsche Telekom to more easily exploit frequencies below 6 GHz to provide a wider 5G coverage over which signals will travel farther than in higher frequency bands. Bruno Jacobfeuerborn, Chief Technology Officer at Deutsche Telekom AG, said: "Deutsche Telekom takes this real world first step toward a 5G network launch and we will be commissioning it in 2018 to provide a broader Laying the groundwork for deploying and providing the facilities needed for mass markets in commercial locations. " Zhu Huimin, vice president of Huawei's 5G division, said the company is helping Deutsche Telekom to prepare for the commercial launch of NSA by 2020. All this shows that Deutsche Telekom plans initially to use 5G to secure the market demand for faster mobile broadband connectivity, including the use of the NSA standard and 3.5GHz and other "midrange" spectrum ranges. Deutsche Telekom is one of the most optimistic 5G technologies this year among the major telecom companies in Europe. In a speech at the World Mobile Congress in February, CEO Timotheus Höttges announced plans to deploy 5G across Deutsche Telekom's entire network by 2020. While Höttges did not reveal details of any deployment goals, other European operators appear more cautious in their respective statements on the 5G. Even so, Höttges and Jacobfeuerborn expressed concern about the cost of launching a 5G network. Höttges pointed out in his speech at the World Mobile Congress that research shows that the cost of a 5G network covering Europe as a whole will be between 300 billion euros and 500 billion euros (between 357 billion U.S. dollars and 594 billion U.S. dollars) . In an interview with Light Reading, Jacobfeuerborn said that in order to successfully deploy a 5G network, operators may need to study the mode of sharing network devices. He also believes that in Europe, American telecom tower companies such as Crown Castle International Corp. (NYSE: CCI) may play a role in connecting mobile base stations to fiber backhaul networks. David Wright, an independent industry consultant who is currently advising a national regulator on the 5G issue, also believes operators will have to share the network in order to make 5G deployments economically viable. He told Light Reading reporters that it is wise to adopt a "neutral host" model, a network that is used by many operators. Jacobfeuerborn has also adopted a number of initiatives to reduce the cost of radio access networks (RANs) in a variety of innovative ways, such as xRAN (one involving many major telecom operators and research institutes such as AT & T, Telstra, Verizon, SK Telecom and Stanford University Research project). Jacobfeuerborn noted that by "decoupling" the radio access network control platform responsible for signaling decisions from the user platform carrying the traffic, the telecommunications industry can phase out dedicated equipment and make greater use of "standardized" hardware. This can result in a significant reduction in equipment expenditures. However, most of the cost of deploying 5G may result in the deployment of optical networks - operators need to use optical networks to provide "backhaul" transmissions for faster mobile services. The German government said in a recent 5G strategy document that operators in the country are expected to increase their investment in connected base stations and fiber links. Earlier this year Thomas Dannenfeldt, the chief financial officer of Deutsche Telekom, said that most of the company's 4G base stations have now benefited from fiber-optic backhaul and the nationwide launch of the 5G network is expected to double the number of mobile base stations to 44,000 To 50,000. Analysts believe FTTH networks can support 5G backhaul requirements, but Germany's current FTTH infrastructure is not enough. However, this situation can change. In a recent investor conference call, in response to a question about FTTH, Dannenfeldt said the company will substantially increase its investment in FTTH deployments starting in 2019. However, some industry observers believe that Europe will not deploy 5G networks in large scale in recent years. Bengt Nordström, chief executive of Northstream's Market Research and Consulting Group, said operators are unlikely to invest heavily in building 5G networks as service revenues remain under pressure.
