What is the difference between 4G and 5G?

5G is not just an accelerated version of 4G, but a serious technological leap for decades to come. Between two generations there are much more differences than it seems. Strictly speaking, 5G is not only a new set of frequencies, but an integrated platform that uses the capabilities of wireless networks much more efficiently. Let's define the main differences and breakthroughs ...

 

One of the main differences between the networks of the new generation will be a tremendous decrease in the delay: up to ten times compared to 4G, ideally to the minimum value of 1 ms. At the same time, backward compatibility with the equipment of the previous generation will be preserved, even at lower speeds, all ranges will be supported. So, without communication, the user will not remain in any case, and the transition will pass smoothly.

Finally, 5G is simply faster: the peak connection speed in theory can reach a fantastic value of 20 Gbit / s. But even the "average" 100 Mbps will be a huge step forward - and do not forget about the low ping.

The speed of connection today will not surprise anyone, even if we are talking about the mobile Internet.Much more important is another thing: with enough bandwidth and connection stability, not only personal gadgets will go online. Traffic lights, road signs, personal medical sensors, machine tools and conveyors - the Internet of things will turn from utopia into the mainstream. In fact, 5G removes one of the main obstacles to the network of all electronics in the world. And of course, the usual mobile Internet is not going anywhere - it will just be even better.

 

And even easier? What will change with the arrival of 5G?

 

Almost everything will change. The interaction of electronics with networks will reach a completely different level. And this applies not only to watching YouTube videos on a smartphone, mobile VR / AR solutions will also become available.

The Internet of Things will be massive: there will be a lot of sensors of a new type, and management and monitoring services will be effective due to the absence of network substs.
What is especially important, the development will receive not only smart homes, but also the medical direction (IoMT). Thanks to the emergence of cheap, compact and energy-efficient medical sensors that transmit patient health data, hospitals can be connected to a reliable network with minimal delays.

The approach to the organization of unmanned vehicles on the roads will also change. Now every drone is completely autonomous, but in the future, the machines will constantly “communicate” with each other. Road conditions, speed, the location of pedestrians and even the route - thanks to the 5G network, it will be possible to avoid accidents and optimize the movement itself.

According to the estimates of Qualcomm's partner, IHS, by 2035, 5G will also have a tangible economic effect. The development of a wide range of industries will lead to the production of goods and services worth about 12 trillion dollars.

By 2035, the 5G value chain (ie, OEMs, telecom operators, content creators, application developers and consumers) will be able to independently provide up to three and a half trillion dollars of total revenues and create up to 22 million jobs. This is enough to employ, for example, the entire population of Beijing.

 

What is needed for the early introduction of 5G?

The frequency bands used now for mobile communications are already too busy, and it is becoming more and more difficult to find free ones for new standards. Therefore, it is important to learn how to get the maximum from the entire frequency spectrum: below 1 GHz, from the average range of 1 to 6 GHz and high, known as the millimeter range.

You will also have to ensure simultaneous operation of client devices on licensed and unlicensed frequencies. But at the same time teach these devices to connect in a new way, including directly to each other, which will reduce the load on certain sections of the network and make communication between customers faster and more stable.

This, in turn, will require the introduction of innovative technologies. But not as a separate infrastructure, but on the basis of an existing one. There is no one technology, the key to create 5G. New generation networks are a whole range of innovations: high-bandwidth and low-latency solutions, band allocation methods, antenna and channel coding technologies, Massive MIMO and many others.

How much will a 5G connection cost?
It is not yet known exactly. But in the future, one of the tasks of 5G is to reduce the cost of data transmission in comparison with 4G LTE. Savings can be achieved by using a wider spectrum of frequencies. This will give mobile operators the opportunity to provide users with unlimited online access even with the growth of the subscriber base.

Over time, 5G may contribute to the popularization of augmented and virtual reality: AR and VR are already available using 4G LTE, but run up against tariff restrictions. 5G should not have tangible limits in terms of speed, delay, or the price of traffic.

The popularity of the mobile Internet is difficult to deny, because a smartphone is a modem that is always with you. Streaming services are actively replacing file sharing: why download a movie if you can watch it online? And distributing Wi-Fi directly from the gadget is as easy as turning on a flashlight. And perhaps in the near future will end not only the era of the slow Internet, but also routers - they will be replaced by the usual smartphones and tablets.
