Although at first we were promised something with 5G, in reality… it is still far from being completed and meeting all the expectations we had. And it is that, they sold us 5G as one thing, when there is still a long way to go to achieve all the promises made to us with these next-generation networks.
At the moment, we are facing a pseudo 5G, more than anything, because the real coverage for this mobile network has not yet been recorded, and to this we must add that the base stations are being equipped with DSS (Dynamic Spectrum Share) technology with the objective of “take advantage” of 4G coverage. And that’s not all, but, in any case, this connection for now does not offer the true technical advantages that it promised us.
There are different types of 5G
One of the first points to deal with is that there are different types of 5G, specifically, we are talking about the 5G NSA and 5G SA. And it is that, between both connections, there are very important keys that must be taken into account when understanding the true characteristics and benefits of this latest generation mobile connection.
The harsh reality is that we only enjoy, at least during these initial years, the 5G NSA network, which promises transfer speeds of up to 2 Gbps download and 150 Mbps upload. Instead, the 5G SA It is precisely what they sold us at the time, a technology capable of achieving a connection that offers us a download speed that part from 20 Gbps. Not counting latency, which is only 1 millisecond, versus NSA’s 15 milliseconds.
Even the architecture of both networks is different. In addition, when checking this series of deployments of this fifth generation network, it has been seen how radio base stations use 4G to have the so-called 5G DSS. So we would be in practice before a “fake” connection, since they upload their software to the 4G stations. So they share frequencies. Instead, the real 5G It has to be deployed on official frequencies that Europe has chosen, such as the bands of 700MHz, 3.5GHz or, in the future, the 26ghz.
The characteristic 5G DSS
Though the 5G NSA is also 5GThe truth is that they have big differences. So, until we get to take advantage of all the virtues of this fifth generation network, there is still a lot of work to do in terms of deployment.
And not only this, but, for now, it is much faster and cheaper to deploy this connection by inserting that necessary software in the stations of the 4G networks to get this characteristic 5G that comes with an extra (5G DSS). But, as we have been pointing out before, the shortcomings are obvious.
In any case, still 20 Gbps are a long way off of this mobile network that they sold us at the time. Or the latency to 1ms. The most striking of all is that what was achieved by current 4G+ networks It is somewhat similar to the experience that can be experienced with the NSA fifth generation network in terms of the theoretical maximum download or upload speed. But, obviously, the 5G NSA is above. Although it is very far from the SA.
One last point to note is that, from the Ministry of Economy itself, according to its report on broadband last year, although DSS technology stands out, «4G and 5G spectrum utilizationdespite allowing the extension of this fifth generation network in a faster way, «the speed of 5G DSS will be limited to the 4G port, so the benefits will be very similar«.
