What is 5G? – Everything about fifth generation mobile networks | TechBuzz

- Advertisement -



10 years is now a common term for changing generations of mobile networks. Of course, the start time of specific commercial networks may vary. Although the first tests began there sometime in 2010, the first commercial 4G networks in Europe started operating a year or two later, including in Croatia.

The planned start of operation of the first commercial networks of the fifth generation is scheduled for 2020, and several test networks are already in operation. Of course, the road to commercialization is long and it will take some time to grant concessions. At the moment, there are no details about the frequency spectrum on which 5G networks will work, but the GSM Association has determined several criteria that should serve as a standard:

1-10 Gbps actual speed, not maximum
1 millisecond end-to-end latency
1000 times more bandwidth
10-100 times the number of connected devices
90% perception of availability
100% coverage perception
90% reduced energy consumption
Up to 10 years of battery life for small IoT devices

Of course, these standards will not be easy to reach, and some will definitely need to be further clarified or refined. Once 5G networks are up and running, they will almost certainly bring faster download speeds, which is the most important thing for most users. Even some current LTE-A networks reach theoretical speeds of up to 1 Gbps, but with 5G, if the GSMA is to be believed, this will have to be the minimum.

In such conditions, downloading high-definition movies will be measured in seconds, and the overall impression of video streaming will be much better. Many will now say that this story could have been heard when the first 4G networks were launched, but it should be remembered that then there was practically no 4K video, and we downloaded movies of the highest resolution significantly longer. Now that time has been reduced to five or six minutes, depending on the quality of the signal. On 5G networks, that time will be maybe 5 seconds, but resolutions, sound quality and other aspects will certainly increase over time, so such content will again take more time.

Also, around 2012, a live stream via YouTube required reducing the resolution to 320 or even 240p to be watchable without stuttering, and now we can stream HD or even 4K quite normally if we are in an area with good signal coverage.

In addition to speed, 5G networks also bring a greater number of channels. The purpose of this is to increase capacity and enable the connection of 10 to 100 times more devices, since 5G technology largely relies on IoT (Internet of Things), i.e. various small devices that will also be connected to the Internet. I’m not just talking about smart watches and other wearable devices, but also smart cards, tokens, and many other electronic devices, the usability of which will rise to a new level once they are connected to the Internet and can be accessed remotely via computer or smartphone.

Coverage, or the perception of 100% coverage, will not be easy to achieve, and a good part will depend on the frequency spectrum. We know the rule that the lower the frequency, the greater the range of the signal, but this can also be changed by amplifying it. Here now comes the trap of the imperative of less energy consumption, but it remains to be seen how the GSMA envisioned a 90% reduction in consumption in the first place.

When 5G networks become operational in 2020 (and perhaps earlier), we should not expect instant spread and coverage. The same story was with 4G, so the networks expanded and improved over time, and in Croatia we even got a flat tariff. We saw that Tele2 offered the first real unlimited tariff, without stupid clauses printed in fine print, while HT and Vip followed it up by further adjusting their tariffs or introducing free streaming for certain services. The point is that mobile data has become cheaper over time and is available to the widest range of users, and 5G networks will only continue this trend.

Devices? Of course, in addition to watches and cards, 5G will also be supported by smartphones, but the mass appearance of those with 5G support should not be expected anytime soon, at least not this year. It is possible that manufacturers will initially release only certain models that support 5G, so that the network can be tested, and 5G as a standard in mobile phones may not start until next year or 2020, when the networks are commercially available.
