5G coming, what will it bring?

3G and 4G are designed to connect to humans, and 5G is designed to connect to everything. 4G network will care about your online video clarity? Flow is not smooth? But will not care about how to better use the mobile phone to control the home door handle, intelligent refrigerator, and 5G expressed great concern.

5G Network

MWC 2015,5g became the focus of attention. 4G is not finished, why do we need 5G? What kind of experience does it bring?

Starting with a live game.

July 8, 2018, Moscow Luzhniki Stadium, Russia World Cup finals.

You are not on the scene, you are on the train on business trip, holding a tablet to watch live broadcast online.

However, you don't look like you're watching live, it's kind of like playing PS live football games. You use your fingers to move around the screen randomly, and the live screen changes as your fingers move.

This is called personalized experience sports events live, as long as the finger, you can enjoy from any angle to watch the game.

The traditional live screen depends on the angle of a single broadcast lens, and the audience on this side is very passive. If your favorite star is in a bad game, you rarely see him. If you have a sudden goal, you can only see the goal hero's carnival, but can not see the defenders of the frustration of the expression.

With this personalized service, how to watch the game is entirely up to you.

This is because the stadium around the installation of a large number of high-definition cameras, these cameras are all connected to the 5G network, a huge amount of video signal through the 5G network from the remote Moscow instantaneous transmission to your flat, the perfect experience of absolute 360 degrees without a corner to watch the game.

This is by no means a personal fantasy, in fact, I believe that 5G will certainly break out in a major international event, like a young star, who became famous for the World Cup, which may be the 2020 Tokyo Olympic Games, may also be in advance, such as the 2018 Korean Winter Olympics ...

What is 5G?

You may have the question, is not more than the installation of a few cameras to connect to the network? 4G can't be achieved?

To answer this question, let's take a look at how the communications Daniel designed the 5G network.

You're not a communicator, maybe you can't read it.

Simply put, 3G and 4G are designed to connect to humans, and 5G is designed to connect to everything. 4G network will care about your online video clarity? Flow is not smooth? But will not care about how to better use the mobile phone to control the home door handle, intelligent refrigerator, and 5G expressed great concern.

To connect everything, you must redesign and optimize your network from three aspects: capacity, speed, and latency.

According to the authority of the forecast, by 2020, 5G network to accommodate 200 billion level of equipment or machinery, smart city alone, intelligent transportation, industrial automation three will need to connect nearly 30 billion equipment. So many equipment influx, network capacity must be infinite, speed must be high enough, only in order to ensure the high reliability of the network. Connecting people and connecting machines can be different, people can always endure, speed slow I patience and so on, the signal is not good I find a mountain to call, the machine can not so good patience, always can not because of the Spring Festival brush Red Envelopes Too many people, traffic surge and lead to the whole city of intelligent traffic paralysis!

In order to ensure the high reliability of the network, the network delay is optimized, the 4G network is 10ms-level delay, and the 5G network is the 1ms-level end-to-end network delay. 10ms and 1ms, the difference is not felt when you surf the Internet, but the machine is different. We say that traffic accidents happen in between, and if your driverless car reacts at a speed of 10ms, how many traffic accidents can you imagine?

What drives 5G?

Smartphones drive 3G and 4G networks to develop at a high speed, so who will be the biggest driver behind 5G? Just as no one had expected such a big boost from smartphones, the biggest driver behind 5G was hard to predict.

However, it is certain that the 5G network will extend the smartphone (or tablet) indefinitely to a more complex and broader application area. Smartphones, for example, connect smart homes, drones, robots or unmanned vehicles, and these applications will be implemented within 5 years.

The 5G network achieves the scalability, versatility and efficiency of the network in real sense. Although we cannot predict who will be the biggest driver of the 5G network, we can imagine what 5G will do.

In the current hot wearable equipment for example, the size of the device is too small, limiting its computational processing capacity. If you rely on high-speed, low delay 5G network, wearable equipment through the 5G network to connect to the cloud service system, computing processing function in the cloud, and then back to the wearable equipment, which provides a great product design space and application design space. Perhaps, a smart watch only needs a screen is enough!

With the advancement of information technology, such imaginary space will be further expanded.

Moore's law tells us that when the price is constant, the number of components that can be accommodated on the integrated circuit increases by one times every 18-24 months and the performance is increased by one fold.

Benefiting from Moore's law, the 5G era will achieve a highly integrated communication and computing technology.

Let me give you another example. Wireless communication Theoretically, the more antennas, the higher the spectral efficiency and transmission reliability. Large-scale MIMO technology (multi-antenna technology) is recognized as one of the key technologies of 5G. In fact, the 4G also uses multiple antenna technology, however, multi-antenna technology is limited by the size and cost of the handset terminal. However, as more and more components can be accommodated on the integrated circuit, the price is getting cheaper and more easy to realize. Look at this picture below, 16 antennas can already be integrated in 5 mm.

In short, 5G will be a new wireless era, the human digital Life to bring unlimited imagination, even, it will add a new dimension to the whole world!
