5G test exceeds 3 Gbps using different frequency bands



Qualcomm announced in partnership with the Japanese Fujitsu to carry out a 5G network test with speed higher than 3 Gbps (gigabits per second). For comparison, the average speed of fixed broadband in Brazil is practically 100 times lower that obtained by companies.

This number was reached without using the faster 5G frequencies, the mmWave or millimeter waves. A device equipped with the Snapdragon X55 modem – the same present in the Snapdragon 865 of the 2020 line tops – connected to a base station in the Fujitsu using the 3.5 GHz and 4.9 GHz frequencies in aggregate. The technique allows using more than one connection simultaneously, multiplying the access speed.

According to Qualcomm, the X55 modem is capable of maximum (theoretical) speeds of up to 5 Gbps. Despite occupying more frequencies available on the antenna, the technique allows to “release” the connection more quickly, which in theory can lead to a more efficient use of the structure.

Another feature of the test was the use of a non-autonomous architecture – non standalone architecture (NSA) in English – which simplifies the implementation of the communication network, taking advantage of part of the structure already used by 4G.

It is important to highlight that the speed was obtained in a controlled test and, in practice, we can expect a lower result than the test. In Brazil, the new generation of the cellular network is still expected by 2021.
