sz-5G

The mobile industry has already begun to experiment with networks of the fifth generation – 5G, and the results are impressive. According to some preliminary tests 5G networks have extremely low latency of 1 millisecond (if 4G is about 50 ms), it is enough to download 10 full-length films only for a second.

Expected 5G networks to make revolution in mobile technologies and Internet of Things (IoT). However, when this will happen is still early to say, but the most optimistic forecasts for the placing of the first commercial 5G network are 2020. Like the 4G network then it will take years for the proliferation of technology.

Why 5G?

It is expected that mobile data usage to increase significantly over the next few years. From smartphones and tablets to connected cars and intelligent appliances, there will be many more things about the internet than ever before. Current 4G networks will not be able to support the Internet of Things. 5G, on the other hand, can theoretically manage connections 7 trillion devices, which means that everyone on the planet should have about 1,000 connected devices to overload the network. Furthermore, 5G networks will be more energy efficient, saving up to 90% energy consumption compared to current systems. Of course, as already mentioned, 5G networks will be extremely fast.

Technology

Next generation networks will use MIMO (multiple-input and multiple-output) technology, which uses a set of small antennas, which each manage data flow. Each user is served by a separate antenna, which eliminates the problem of clogging of the available radio spectrum with very competitive devices: each antenna will be responsible for only one device. In the past, barriers and distances created problems for wireless connectivity. But some companies have found a solution and it is in the so-called “millimeter wave”.

Potential obstacles

The biggest challenge 5G is standardization, as there are already many groups working on solutions for collaboration, compatibility with older technologies and ready to meet the future needs of the mobile world. The best solution is selecting a global standard, but it is unclear whether this will be found and that all stakeholders will support it. Then comes the issue of the necessary infrastructure, the allocation of frequency needs etc. 5G will rely on higher frequencies where there is more spare capacity, but it will lead to higher capital costs, since these waves have a relatively small range and need more base stations and MIMO antennas to cover an area .
