Operators and manufacturers of telecommunications equipment are increasingly assuring us that the upcoming 5G networks will easily handle data transmission at a minimum of 1 Gbps. These assurances are supported by news published from time to time on the results of the next generation of tests. However, the SRG group has doubts about the performance of the system built by the American operator Verizon, whose base stations are to operate on frequencies in the 28 GHz band.
SRG (Signals Research Group) is a consulting company specializing in the analysis of wireless systems. Verizon is an operator that is at the forefront of companies dealing with 5G. There is a widespread opinion on the Internet that base stations operating in the 28 GHz millimetre band will have very small range. In turn, Verizon intends to use these frequencies to provide a fixed wireless Internet service. This means that 5G is going to replace not only Wi-Fi and WiMAX based solutions, but also fiber links. Verizon promises that the 5G network will provide Internet connection with 1 Gbps speed for every customer.
Specialists have doubts whether 5G can meet the requirements.
The SRG carried out the world’s first independent tests of the 5G operator network. Verizon has built in Houston the 5GTF test network that is not compatible with the global 3GPP standard. However, researchers are convinced that the conclusions regarding the behaviour of radio waves at the 28 GHz band are quite universal in this case.
