5G networks have not yet been created, and everyone is praising them. Although these theses are confirmed by tests, they are performed only in the presence of a single subscriber device. Qualcomm, on the other hand, decided to check how the 5G network will behave in the case of a load generated by many concurrent users. The developed simulations are very detailed, and the results show that 5G networks will pay not only to operators, but also to users who observe the actual acceleration of data transmission.
We all know well what are the main limitations of the mobile Internet. The maximum download speed of several hundreds Mbps is not a purely theoretical value. However, in practice it is difficult to get results at this level. Speeds given by operators are only available in good radio conditions and with the assumption that only 1 user is using the base station. In practice, we are dealing when data is simultaneously downloaded by many people who are at different distances from the base station. That is why Qualcomm simulated for 14 000 users located in the area serviced by the LTE – 5G NR hybrid network.
Qualcomm shows that 5G networks will actually produce a 10-fold increase in performance
The first simulation was based on the model of the Non-Standalone (NSA) 5G NR network located in Frankfurt. It was assumed that the 5G base station uses a 100 MHz frequency block in the 3.5 GHz band and works with a 1 Gbps class LTE network (i.e. aggregating 5 frequency bands). The results are quite interesting. The average download speed for the LTE user is 56 Mbps. In the case of 5G devices, this result increased to 490 Mbps. Meanwhile, the average delay decreased from 116 ms to 17 ms. As many as 90% of 5G users downloaded data at speeds above 100 Mbps. In the case of 4G networks, this result was only 8 Mbps.
The second simulation concerned a network located in San Francisco, which uses an 800 MHz frequency block from 28 GHz mmWave band. In the same area, a 1 Gbps class LTE network has been modelled, using 4 licensed LTE bands and an unlicensed 5 GHz band (LAA technology – License Assisted Access). In this scenario, an even greater increase in performance was observed. The average data download speed for 5G users was as much as 1.4 Gbps, whereas in the case of LTE networks it was “only” 71 Mbps. The delay decreased from 115 ms to 4.9 ms. In contrast, 90% of 5G network users downloaded data at speeds greater than 186 Mbps compared to 10 Mbps achieved by LTE.
