5G technology is not yet ready, but 3GPP 5G New Radio standard is almost done. Of course, manufacturers of base stations and terminals can not wait with their hands on finalizing work. That is why engineers have been working on this technology for a long time. Recently Deutsche Telekom demonstrated the first 5G base station provided by Huawei and working in their commercial network.

It is not known from today that operators long before the introduction of new technology cooperate with suppliers of telecommunications equipment. As a customer, they test new solutions first in the lab and later in the field. As you know, the first commercial 5G networks will appear on our continent in just 3 years. Work is going well, because operators are waiting for a 3GPP compliant solution, which will allow devices from different vendors to work together. Huawei boasts a base station in line with the current unfinished version of the standard. T-Mobile Germany engineers have adapted this equipment to their network.

Deutsche Telekom is gearing up for 5G working in the 3.7 GHz band.

Are you surprised? In the United States and Korea, work is underway to introduce a new generation of cellular networks operating in the millimeter bands, i.e. 28 GHz and 36 GHz. However, the power of the radio signal with such high frequency is rapidly decreasing as the distance from the antenna of the base station increases. That is why many people are concerned about the 5G network. But such the real 5G system will operate on any frequency band, including those used today by LTE and other radio systems. That is why T-Mobile wants to introduce the 5G in the 3.7 GHz band used by the WiMAX system. True, coverage will be worse here than with LTE. That’s why Huawei’s solution lies in the parallel operation of 4G LTE and 5G technology. This means that all terminal mobility operations are carried out via an LTE network and 5G is used only for data transmission.

Such a combination of both technologies allowed for a speed of 2 Gbps and a delay of 3 ms. This means that data was transmitted only via the 5G base station, and LTE was used for signalling. The use of such a hybrid solution is a sensible approach. Thanks to that the cost of building a 5G network will not be so big.
