Deutsche Telekom, the German T-Mobile, has boasted of the first 5G base station in Europe a month ago. This time we are dealing with an oil step that is to build the first small 5G network. It consists of 3 base stations, which are located in the Schöneberg district. Berlin is not the only city where T-Mobile is testing 5G. Similar work is also being carried out in Hamburg.
The first results are promising, because the operator achieved stable 2 Gbps data rate. Of course, 5G will allow for much higher speeds. However, we also have to keep in mind that, as with LTE, the 5G transmission speed will also depend on the bandwidth. The mentioned 2 Gbps is good news for everyone as T-Mobile in its first 5G network uses a 3.7 GHz band. The same frequencies are currently used in many countries by WiMAX networks, but they will be adopted in the future for 5G.
T-Mobile’s 5G network works in 5G-LTE dual connectivity mode.
Operators know that building a new technology network from scratch is very costly and take a lot of time. That is why Deutsche Telekom decided to make a hybrid solution. This means that the client device will mainly use an LTE network that is already in good coverage, and when it is within 5G cell range, it will use the new technology to transmit data. However, all signalling information will be transmitted via LTE base stations.
The first 5G base stations are located in Berlin on the following streets: Winterfeldtstraße, Martin-Luther-Straße and Pohlstraße. They are equipped with Huawei hardware, which supports 5G NR (New Radio). The whole problem is that 3GPP has not yet released the final version of the standard for the next-generation network. Therefore, telecommunications equipment providers are not yet sure how to implement new solutions. Deutsche Telekom promises that as soon as the standard will be clarified, next year they will build the foundations for the development of new technology.
