The coming days are of 5G. Which means that the 5th generation of Smartphones. 1st generation has given us Phones which help us to communicate with others. 2nd generation provided us with the facility of sending message and voice recordings. 3G was about the uses of Smartphones and digital broadband. Then 4G provided speed those things or we can say that 4G is the modified version of all the above.


But, 5G is as same as that to go to Mars from the Earth. It is not just different but also it will be a different world to all. In 5G the machines will talk to each other and also talk to us. Before 5G, we used to give instruction to machines but after 5G machine will take advice from us or they will be able to make decisions on their own. On the way, we will amaze to see that our cars are taking with other cars i.e.
self-driving cars taking data to each other. 5G will also bring perfection in humans working module.
This perfection will be possible only for the good decisions by the machines with the help of 5G.


If 5G will be very much efficient and it will be going to bring this drastic change in the life of humans.

The first question which arises in our mind that how will it happen? This question must arise in our minds. So let's try to find out about the working module of 5G. There are mainly 5 points which make 5G possible:-

1. Millimetre Waves:- This is a high-frequency wave whose frequency is about 30GHz- 300GHz. This wave is the identity of 5G. Due to high frequency, its speed increases approx 100 times of 4G's. But as we know that every coin has two sides one is good another is bad like that millimetre waves have some weakness in it:-
  (a.) It can not cross anything coming in its path. (e.g-building, cars etc.)
  (b.) It stops working at bad weather i.e. it could be absorbed by the trees or clouds.
 (c.) It can not travel long distance due to its high frequency or high speed.


 2. Small Cells:- In one word small cells are the backbone of the 5G network. In short, small cells make use of low-power, short-range wireless transmission systems that cover small geographical areas or small proximity indoor and outdoor spaces. This feature makes them perfect for 5G rollout that promises ultra-high speeds, a million devices per square mile and latencies in the millisecond range. 





3. Massive MIMO:- MIMO(Multiple Input Multiple Output) deployments use multiple antennas that are located at both the source and destination. Those antennas were linked in order to minimize error and increase the efficiency of a network. Massive MIMO, as you might guess takes MIMO                      technology and scales it up to hundreds or even thousands of antennas and terminals. These antennas attached to a base station focus the transmission and reception of signal energy into small regions of space,  providing new levels of efficiency and throughput. The more antennas that are used, the finer the spatial focusing can be. 



4. Beamforming:-  Beamforming is a traffic-signalling system for cellular base stations that identifies the most efficient data-delivery route to a particular user, and it reduces interference for nearby users in the process. Depending on the situation and technology, there are several ways to implement it in.




     
           5. Full Duplex:- With 5G a transceiver will be able to transmit and receive data at the same time on the same frequency. This technology is known as full-duplex. To achieve full-duplex in personal devices, researches must design a circuit that can route incoming and outgoing signals so they don't collide while an antenna is transmitting and receiving data at the same time.



         
This is the full working module of 5G. Now let's see some of it's significant:-

According to the MIT Technology Review in the 5G network has 100 times more than the speed of 4G. According to IEEE(Institute of Electrical and Electronics Engineering ) in the 4G network, a movie downloading time 10 minute but in 5G network time will be only 1 second.

5G network will mostly be used in:-
1. Virtual Reality

2. Self-driving cars

3. Remote Surgery

4. Cloud Gaming
