5G

5G

Hey everyone,

                        Today I'm going to discuss about the 5th generation of cellular technology. After 2g,3g,4g now comes 5g, It is said that it would revolutionize the way we use internet by providing lightning fast data transfer rate,cost reduction, energy saving and capable of connecting lots of devices simultaneously and streaming without drop in speed on each device. The bandwidth is extremely high and the latency is extremely low this makes streaming with lots of devices an easy task.

What is 5G?

5G is a software defined network which means that it will be predominantly operated on cloud. Thus replacing cables for data transmission but not entirely.

Hence having extremely higher speeds and capacity than 4G, for example, to download a HD movie in 4G requires nearly 6 minutes or more but using 5G we can watch the movie in less than 4 seconds lighting fast right?.

The 4G network has a response time of 50millisecond but in 5G it is 1millisecond.

Why do we need 5G?

Now-a-days the world is completely relying on the internet to function and a delay on the internet is not tolerable in most applications the quicker the data is received the better it is.

As we all know autonomous cars are the future and for autonomous cars to work the data response rate should be very high any delay in information can cause catastrophic failures. So lesser the delay better the performance.

Internet of things is going to be 3 times as bigger as it now in the near future and not just for controlling home appliances or robots but for medical surgeries, Industrial automation, agricultural sectors etc.

Network slicing

5G is aimed at providing customized web experience using a technique called network slicing. It is creating separate networks on cloud and using them for wide range of applications example for online gaming we need seamlessly high response rates and greater data capability than a person just using facebook. The data capability can be personalized depending upon our need.

In business some departments may require heavy and large amount of data than others so the organization can particularly pay for only what it needs, this is cost effective and reliable. The data won't be exhausted and last longer due to this.

So, why we are still at 4G?

Ya, we can't see 5G in use till 2020 and implementation will start only by 2025 till then we are stuck at 4G.
It faces several hurdles the first thing is its course of cost, establishing 5G makes current network operators tear up their current business model and create a new one.
For example, 3G and 4G were relatively easy to set up as they were cheap and can be accommodated with the existing spectrum of radio frequencies(MHZ) with ultra high frequencies. 5G operates in a super high frequency range(more than 3GHZ) as of now only satellite communications works in this range. 
Thus establishing 5G requires a lot of money and infrastructure so network operators will be forced to work together. Countries with minimal mobile network operators like China can adapt and work with it but countries such as India having a large number of mobile operators 5G will always be a dream.

Currently Huawei and ZTE are going to be the first to start 5G trials and Asia's 5G network market is going to be owned and controlled by them at starting stage but the US won't keep quiet they are planning on equipping almost 50% of their country's mobile users to 5G and the industrial zones are going to be equipped even sooner.
AT&T is planning on establishing 5G in some major American cities by 2019.

5G may be awesome for streaming your favourite tv show in 4K or 8K resolution or play games at 144fps or 300fps seamlessly but there is a catch it is so harmful.
Imagine if Gbps of data is being streamed on your mobile phone then how much strong and powerful the radiation surrounding your mobile phone will be.

Fact Flash:

Small cell

      As of now, there are no regulations being set up by 5G in particular. The data streaming speed is going to be about 20Gbps even in India we can expect upto 1Gbps data transfer rate. To achieve such high data transfer rate "5G small cell" is to be placed in trashcans,streetlights,utility poles,bus stops,sides of building. It is not as small as you think and each cell contains a antenna and the radiation emitted from them are extreme.
