what is 5G, How 5G Works and when will 5G Launch in India

What is 5G?

5G is the latest development in wireless information transfer technology. The G in 5G stands for generation, so this is the fifth generation of cellular technology which will help mobile to connect with different machines and objects. In 3G we were able to connect mobile to mobile via Bluetooth or hotspot. In 4G we saw we can connect mobile to different objects like TV, projectors, AC same like this 5G brings a revolution by enabling us to connect to cars, machines and various objects. If you have heard about IoT (Internet of things) then it is possible with help of 5G. In a very abstract manner, Internet of Things is the idea of connecting all devices and making them interact in the seamless way.

5G provides us High speed data as compared to 4G; 5G provides 100 times more data speed like 4G provides us 100 Mpbs whereas 5G can provide 10 Gpbs speed (these are theoretical values) practically 4G provides data speed 15 Mbps while 5G is assured to provide a Minimum data speed of 50 Mpbs when we watch ultra HD video on Netflix it requires data speed of 25 Mbps while 4G can provide data speed up to 15 Mpbs. Due to these reasons we experience lag in streaming videos but 5G is going to provide 50 Mbps data Speed hence video streaming will be smooth. Here we can see there is no significant difference in data speed of 4G and 5G But 5G is better in latency than 4G latency or response time simply is time difference between action and reaction. when we stream videos on YouTube and suddenly we change the video quality from 144p to 1080p then we experience a lagin 4G latency is 50 milliseconds whereas in 5G latency is 1 millisecond. Humans have latency of 10 millisecond and with latency of 1 ms in 5G we will experience things smoothly because of this latency we will be able to connect mobile with different objects. Using mobile as a remote we will be able to control cars and different objects due to less response time.

5G works differently from 4g by replacing large, high power cell towers with many more cell stations spread out across a city. This is one disadvantage of 5g tech, in testing users reported dropping out of service when more than two blocks away from a tower, so telecommunications companies are going to have to invest heftily into out fitting each city with thousands of new antennas. Luckily, these antennas are far smaller than normal cell phone towers, and can be inconspicuously worked into light poles or the roofs of buildings. The reason for the change from large, powerful cell towers to a swarm of smaller antennas is because 5g operates at a much higher frequency than 4g coverage, operating between 30 and 300 giga hertz. This means that the electromagnetic waves 5g uses for communications are much smaller than those used for regular cell service, and are thus much more prone to interference and have far shorter ranges. However, 5g promises to make a truly inter connected world a reality.

How does 5G Technology Works:

Today, the greater part of the gadgets that we use including TV, cell phones, radios, etc chip away at radio waves in the electromagnetic range which have frequency between 3 kHz and 6GHz. There is only a limited number of bands that can be used and this is where the first innovation the millimetre waves comes into play. The ideology here is simple and that is to open up the higher end of the spectrum from 6 giga hertz onward for usage. While that sounds pretty straight forward, these high frequency wave have a big disadvantage and that is the fact that these waves cannot travel for longer distances like the waves that we use for present-day communication. This is due to high scattering and even buildings or trees might obstruct these waves. Strangely there is a wonder called downpour blur which actually implies that millimetre waves can be blurred by downpour. This is where our second innovation called small-cell networks comes into play. By this, alongside the fundamental pinnacle a great deal of littler base stations would be introduced which would go about as a promoter to these signals. A great deal of times we expect associations with be more focused on one spot than the other like a cricket coordinate or a Mobile World Congress.

This would mean two things: the higher the capacity that the tower should have and the lesser interference that the wave should do. This is where massive MIMO or Multiple-Input Multiple-Output and 3D beam forming helps. With massive MIMO technology the number of antennas in a tower can be increased up to a theoretical maximum of 256 nodes And 3D beam-forming technology helps the task to transmit waves in multiple directions there by reducing interference. 

The two more innovations of 5G are called network slicing and full duplex. Full duplex helps out in over coming reciprocity of antennas with which antennas can send or receive data simultaneously rather than taking turns like it does with the current technology. Network slicing is a way of creating separate wireless networks on the cloud allowing users to create personalized internet experience.

5G is poised to change humanity in a very big way, and in fact may be the single biggest revolution in human culture since the global adoption of the internet. That's because 5g technology will allow information transfer rates as high as a stunning twenty giga bytes per second, which is faster than most wired connections. More bandwidth and improved antenna technology will make it possible to share more data, faster, anywhere within network coverage. We could see latency drop to as low as 1 millisecond, meaning that for the first time wireless augmented reality technology could become a real thing. This means that you could play virtual reality games anywhere that you have coverage, but it would also allow for things like remote surgery in more places.

If we talk about more features then 5G can handle traffic efficiently than 4G. If we see traffic handling capacity of 4G then 4G can handle 4000 devices in 1 sqkm, whereas 5G can connect 1 million devices in 1 sqkm. More traffic can be handled more efficiently in less area. Every user connected to 5G network will get good network coverage most of the times. 4G network used to shift to 3G when the network frequency was less. 5G operates on 3 frequency i.e low, medium and high with help of 5G we can connect mobile to objects which are wifi enabled this is core advantage of 5G. we will be able to use IoT and VR(Virtual reality).

When will 5G Launch in India?

In North America South Korea and Japan, there is already a handful of places in which you can get 5G. For the rest of the world including India 2020 is the expected year.India will also have to develop proper infrastructure for 5G. In 4G optic cable was used similarly 5G will require to expand optic fiber from 2.5 million km to 7.5 million km.
