Recently, many telecommunications companies and mobile network operators have been praised for the breakthrough results of new technology tests. Everyone wants to point out that he did something first. What did Nokia manage to do? Finns operate on several fronts. In the United States, the Finns carried out a successful switch-over test between the two 5G sectors. In China, however, we managed to achieve data transfer of 1.4 Gbps with an independent subscriber device prepared by Prisma. Both tests are 100% compatible with the 3GPP 5G NR standard.

It might seem that Nokia is far behind when it comes to the rate of hardware development that will allow the construction of the 5G network. Ericsson is also in a similar situation. However, Huawei and Samsung are the leaders who have had many successful 5G tests. However, there is one significant difference between these companies. Samsung and Huawei are also involved in the production of mobile chipsets, so they can conduct demonstrations using prototypes of their own 5G modems. In contrast, Nokia and Ericsson only deal with the elements needed to build a mobile network. Therefore, when organizing such demonstrations, they rely on cooperation with companies preparing new mobile chipsets. Usually it is Qualcomm. On the other hand, Nokia is strongly committed to developing a base station 100% compatible with the 3GPP 5G NR standard, which will ensure trouble-free operation of the new technology. Regardless of who will be the producer of subscriber devices.

Successful switching test (i.e. handover) between 5G sectors

I must admit that I am a bit surprised that only now we have heard about the first successful test of switching the connection between the two sectors of the 5G base station. In the end, some time ago, we heard news about new technology tests on racetracks, where a 300 km / h car was switching between 5G modules. Perhaps during these tests some workarounds were applied that did not comply with the standard published by the 3GPP organization. Whereas the name of the company, which was the first to show that 5G NR could be a mobile network, was Nokia. The test was carried out in cooperation with the American operator Verizon, who intends to launch a new technology on the 28 GHz band.

Nokia and China Mobile: 1.4 Gbps for a single user

It would seem that data transfer at the level of 1.4 Gbps using the 5G network is not a big deal. Finally, LTE-Advanced already allows 1.2 Gbps, but no operator has enough bandwidth to reach that speed. However, the success announced by Nokia and China Mobile boils down to the fact that the test was made using the Prisma mobile device simulator. This means that we are dealing here with another test, which proves that Nokia effectively implements the standard adopted by 3GPP.
