According to an official press release, the South Korean company has successfully completed tests of a prototype 5G network, on which it is currently cooperating with the China Mobile Research Institute. The two companies have been working together since June this year, when they are working on the development of a 5G mobile network.
During the tests, which were limited to Beijing only, Samsung confirmed two key technologies for 5G. The first of these is spatial modulation. This is a way to increase the speed of the transferred data, without increasing the bandwidth requirements themselves. The second thing is FBMC (Filter Bank Multicarrier). It is a new way of dividing the carrier signals on different channels, under the condition of the same frequency spectrum.
Both of these technologies were tested at a frequency of 3,5 GHz. Such a high frequency for end customers means only one thing - very good coverage, which will be suitable, for example, for metropolitan areas where there are many cells.
Unfortunately, there is also one big drawback, because it will be almost impossible to use such a high frequency outdoors, or in the open air. So it is more than likely that the coverage will be too limited. Samsung is also working on throughput performance to see how much data can be run on the system without any issues.
