In the beginning of the year on the forum MWC-2018 in Barcelona, one of the Central topics was the new standard of cellular communication 5G. In particular, Huawei has revealed the first processor for base stations. It would seem that it is already possible to build the device and there mobile options will catch up. However, towards the end of the year, Director General of the GSMA, organizer of the event, mats Granryd in an interview with Forbes said, what problem is to be solved and how will the transition to mobile next generation network.
It promises 5G
At the MWC-2018 operators and telecommunication equipment manufacturers have promised 5G the following advantages: increased communication speed, reduced latency signal transmission, energy efficiency and support more devices by the base station.
Speed. To test 5G networks that are deployed in Russia, the transmission speed reaches 1 Gigabit/s, an order of magnitude faster than 4G (LTE). However, it is doubtful that the speed will be the main competitive advantage of 5G devices. For example, for streaming 4K ultra-clear video enough opportunities. Then why a new standard?
Not only the speed. Even playing through a wired connection in a network game, users are sometimes dissatisfied with the delay between when they gave the command, and the desired action in the game. For the existing mobile communication network latency is typically even greater than for a wireless connection, which prevents not only to play but to connect devices to the Internet. For example, if the unmanned vehicle will later receive a command, can pass a turn or choose a suboptimal speed limit.
Connecting devices through a network for collaboration (Internet of things) needs to 5G network. If every home were added to several user devices, a couple of appliances (fridge, washing machine) and a dozen of sensors — the number of devices connected to the network will increase. Caught in a situation when your phone shows that you are in the area of good signal and the call breaks? This is an overloaded base station. The 5G standard will allow each of them to support a greater number of devices, and low latency during transmission of the signal will enable each of them to react.
Finally, the high energy efficiency will not constantly change the batteries in connected devices and will provide an acceptable consumption for base stations.
The introduction of 5G will enable to realize large-scale Internet of things. Unfortunately, the new standard is quite expensive in performance: in addition to more advanced electronics, it will require closer to put the base station. It will likely be implemented locally, in cities and areas with a high density of connected devices.
Forbes: “What is the main purpose of the Association the GSMA?”
Mats Granryd: the Main objective of our Association is to unite all the operators around the world. Now the Association has around 800 operators, and another 350 technology companies, including Intel, Microsoft, Ericsson, Huawei. We carry not only the MWC in Barcelona, but also of the conference on telecommunications around the world: for example, in October in Russia was Mobile 360.
The work of the Association goes in three directions:
Platform and technology. Define the characteristics of 5G, the Internet of things, and work on legislative proposals such as the allocation of frequency spectrum.
Consulting. Help legislators and governments to properly understand the trends and overall picture
— Strategic planning: forecasted what will happen in 5-10 years to prepare the ground for these changes.
The last is the most interesting. What is our technological future?
For example, by 2025 we will see a rise in popularity 5G — share of connections in these networks will be about 20%, another 55% will have 4G and 20% is 3G. The result will be a mixture of these standards, maybe a little left over 2G networks and our devices will automatically select between them using the technology of smart connect. Around earn a lot of connected devices and automatically will be selected the optimal configuration, all worked together.
On the whole, how you see the future of the mobile industry in 10 years?
In 10 years? See this icon — it’s 17 sustainable development goals of the UN. I am sure that in 10 years the whole world will stand together on these objectives: the elimination of poverty, achieving gender equality, adequate education, climate protection, and Thus the UN and all countries of the world together to address important issues. And we as an Association of operators support the achievement of these goals, because we have tremendous reach 5 billion people. If we want to work with all, the achievement of these goals will have an important role.
At the MWC-2018 operators noted that it would be difficult to allocate same frequency range for different countries — it means 5G will not be a unified standard?
It is still early to talk about it. Work is just beginning. Most likely we will be able to work with the 5G standard in different spectra: 700, 800, maybe 900 MHz band (3.5 To 5.25 GHz and 5.75-7,075 GHz), even in the millimeter range 28 GHz (effective for individual homes). The main thing is to have a block of frequencies to allow operators to dispose of all their bandwidth for their needs.
The 5G standard will require a seal at the base stations, whether there will be the danger of the influence of microwave radiation on the human body?
There have been many studies, no one could find examples of the influence, but we will continue these studies. The site has information about our work with who.
Note that when increasing the density of base stations field-strength level falls. For example, in the village level of the upward signal (from mobile to base station) will be much higher than in Moscow, because the tower is located at a greater distance. In the same base station located often and the phone do not need to create such a strong signal, it will be less warm.
Your organization, on 30 October said that Russia will become one of the leaders in the creation of the 5G networks. [Dealt with the penetration of 5G networks by 2025, Russia is projected available for 80% of the population is the best indicator in the CIS). How is that possible?
It depends on what you mean by leadership. You know, USA, UAE, South Korea, China, Europe and Russia, of course, will run until 2020 test 5G network. I don’t think it should be considered as a race. We need to consider it as a step to understanding government and regulatory agencies right of ways introduction of 5G networks and connected devices. Because only Russia requires about $15 billion of capex to launch by 2020 of a network of the fifth generation.
The creation of networks 5G is not so important to be first. Leaders can fall behind if their other statements do not support a homogeneous environment, it would be a disaster. Someone wants to be first, but there is another strategy: well, let them work out the technology, and we will go on the finished track.
The community is connected to the network is a happy society.
There are different strategies, but it is important to discuss the influence of the future of the “connected society” citizens, society and, of course, on the economy. The community is connected to the network is a happy society.
Will there be single chips for different types of generations — 4G, 5G and others — not to make multiple devices running different standards?
Yes, now there are many types of equipment, the chips and base stations that work on 4G and 5G. There are even tablets, but we haven’t yet decided on the frequency, they cannot be considered final, because we don’t know the size of the antenna (antenna size depends on frequency, which is signal transmission — approx. ed.).
All connected devices — TVs, refrigerators, cars — will work on chips that support 5G or part will be calculated only on the existing network?
Perhaps some users will find that they will not talk faster, and they are enough for 4G, someone will take 5G. But if our next meeting will happen in 2022, it is likely that the device will support all frequencies using a single chip. Up to this point allow for a transitional process.
Please make a summary of what problems must be solved to run in a world full 5G network?
The first is a spectrum. All must be harmonized. The government should clear the frequency under 5G.
Second. We need government policies that will contribute to the development of new generation networks: easy construction of new towers, the legislation enabling their sharing (using one operator of the other towers) and similar rules.
And third. We need a legislative regime that we have not considered as a source of income. This happens in Russia, in Germany and in several other countries. But in the end we suffer, we “starve” the money that we receive, we require capital expenditures for construction of infrastructure 5G.
Balanced tax regime is very important and, I think, a large number of governments and operators, sees a connection between good coverage and an increase in GDP of the country by increasing the tax base [of services 5G networks].
Fourth. A very important point is to establish the free flow of information between countries. It is necessary to harmonize the various legislative issues in the field of information security, they should also make you, the user, and do not damage the business. Need local data centers to store data. This is a very important, sensitive question, because the information is the new oil, a sovereign, a national treasure. The one who generates the data has the rights to them and should be able to transfer them if you wish.
It’s very important to solve all these four questions to get the full 5G networks.
