What is 5G? What are it's applications?

Today,I will try to shed some light on this much talked about topic in a simple manner.

✓Fastest network till now

✓While 4G uses the highest frequency of 6 Ghz maximum but 5G will be able to work on much higher frequency of 30-300 Ghz.
As a result it will be able to easily handle all types of networks such as mobile data,Wi-fi,, Bluetooth,etc. without any congestion.

✓The use of I.O.T that is Internet of things will be Moreover seamless and instant. As a result it will help the doctors to perform an operation from distance ,more effectively which is not possible with 4G.
Another instance will be self-driving cars with all sorts of sensors.It will work better with 5G as it has no delay in transferring the data  to the users due to its almost zero latency or response time .

✓5G will give a new dimension to the AR and VR technology. It will enable the users to feel the actual ambience of a place where he is not present! So when you put on your VR Headset you will be able to have a seamless experience like never before.

✓5G will use broadband. It will  use the millimetre wave technology. Though it may have one issue. As the frequency increases it will not be able to penetrate the walls if the towers are far away or if the weather is overcast and rainy it may face some problems. A 3G or 4G tower can cover almost 30 kms but 5G will only be able to cover about 300 meters. So instead of using large towers ,it may use small cell systems in a large number to reach the users to overcome this problem.

✓When we talk about Mimo that is ports used in a tower. The present technology uses 10-12 ports  but the 5G technology may use more than 100 ports in an antenna. So the capacity of handling no.of users per tower increase exponentially.
So it will need to form beams to control all the signals.

✓ With the advent of this technology we will see smarter devices and more smart  buildings or houses.

✓ Simultaneous high speed on both upstream and downstream. Nowadays if one uploads and downloads at the same time ,he will have less speed in one of the aspects but with 5G one can do both the things at the same time without any lack in speed.
✓This new technology claims to deliver 10 Gbps speed maximum which is humongous and futuristic to say the least. In India however,we can expect at least 1Gbps speeds which is more than enough.An example will go like this:
It means one can download a hd movie in about 3.6 seconds compare to 6 to 8 minutes in 4G.!

That's it for today.I Hope you have found this post helpful and informative.If you do please show support by sharing it. Thank you.
