What is 5G?Fully Explained 2020

First came 1G, then came 2G, then the demand of the people came and went big, then came the demand of 3G and people want good internet speed so they demand for 4G and now the people are demanding for a more developed network.

People are not satisfied with the things they have because they always want more.

So the technology will never stop, it will continue to grow.

That's how network technologies are developing.

But if we talk about 5G, then in 5G will we only get to see more speed or will there be more?

Yes, we will see many changes in 5G, not just speed.

So today we will discuss what 5G will be like in the coming times, what will be the benefits to us, and what will be its impact on our lives.

So for the complete information, read this article till the end.

What is 5G?

Every new number that is added before 'G' brings rapid progress in Technology.

The 'G' in 5G refers to wireless cellular technology.

Each generation is not only defined by transmission speed but also advancement and improvement that makes it incompatible with the generation before.

Experts believe that the 5G network will provide the fastest download speed and can transfer more data.

The 5G network will not be used only on smartphones as it is planned for all types of devices such as sensors, computers, cars, even advanced robots and various types of Artificial Intelligence can use this Technology.

What is the difference between 4G and 5G?

We have mostly been using the 4G LTE standard mobile internet.

Now we are transitioning into the 5G.

What makes 5G so special compared to 4G?

The main thing that we should pay attention to is the frequency bands that 5G supports.

With 4G LTE, we could only go up to 2.5GHz while 5G covers a wide spectrum from sub 1GHz(<) up to a whopping 95GHz.

This unprecedented flexibility that 5G allows opens up to seemingly endless new application and hugely surpass the limitations with 4G we have today.

5G frequencies can potentially overlap with 4G but like we mentioned they are not compatible with one another.

So once 5G becomes mainstream, 4G and 3G will become obsolete.

How does 5G work?

And Just I have mentioned 5G covers a wide spectrum of frequency bands.

And based on the frequency used, It can be classified into three types.

1. Low-Band
2. Mid-Band
3. High-Band

They are quite different But the TLDR is that the lower the band the wider the coverage but slower the speed.

Let us dive deeper.

Low-Band 5G

Low band 5G covers the sub-1GHz frequency spectrum which has long been used for cellular connectivity including the 4G LTE that we have today.

This type of 5G has the widest coverage versus higher bands and is especially useful in rural and suburban areas.

it also has the slowest speed which ranges from 100Mbps to 300Mbps and that is similar to the higher end of 4G LTE today.

Mid-Band 5G

Mid band 5G covers the spectrum between 1GHz and 10GHz which is where most of the 4G bands lie as well as Wi-Fi.

Because Wi-Fi routers use 2.4GHz and 5GHz.

This type of 5G sits in the middle in terms of range and speed.

And this fine balance will mean that it will undoubtedly carry the majority of 5G traffic.

In a test by CNET, speeds between 400Mbps and 600 Mbps can be observed in different parts of the world with Mid-Band 5G.

And this includes, the United States, United Kingdom, Korea, and Australia.

Suburban and rural areas will be seeing a mix between Low-Band and Mid-Band 5G.

Well, urban areas should be enjoying mostly Mid-band with High-Band 5G in selected areas.

High-Band 5G

High-band 5G covers the frequency bands between 20GHz to 95GHz.

Most of the crazy 5G speed demonstrations that you have been looking at, is done with High-band 5G.

And because it is not currently used for consumer applications.

There is a lot of unused, untapped but premium real estate in frequency spectrums.

The very nature of high frequencies renders this type of 5G unable to penetrate through solid objects and travel long distances.

This means that High-Band 5G has the lowest range but can achieve the highest speeds.

The theoretical maximum of 10Gbps, although real-world test put it more like 1Gbps to 2Gbps.

Due to these limitations, High Band usually is supported by Mid Band and it is favorable in densely populated areas where ranges are not an issue.

Have you noticed how your 4G connection slows down when there's a lot of people around?

Well, this is due to 4G's lower bandwidth and limited capacity.

With the wide spectrum available on High-Band 5G.

You and every single person should be able to enjoy uninterruptedly fast internet.

How 5G will be our first step for the future?

You can easily say that the speed of 5G will be faster than 4G.

This 5G technology will be the first step for our advanced future.

Simply put, 5G is widely considered to be smarter, faster and efficient than 4G.

It promises mobile data speeds that surpass the fastest home broadband network yet available to consumers.

Very reliable and very low latency in 5G compared to 4G.

One can download and upload files quickly and easily.

You may be able to watch a 4K video almost directly without buffering.

Now you may have question in your mind that "why 5G?"

Now 5G is not just for netflixing at 8k resolution.

It is way bigger than that..

For most of us, besides huge upgrade in mobile broadbands.

We should also be able to enjoy futuristic technology that are stuff of science fiction.

 

5G will be the conduit for the Internet of things or IoT which are smart devices that are interconnected making real time data exchanges.

Machines would be able to communicate with one another to coordinate and perform remarkably complex tasks.

We'll be seeing domestic robots, self driving cars in smart cities, revolutionary developments in industries, medical, agriculture and so much more!

What are the problems with 5G?

Finally, the talk of 5G has started in India.

Nowadays, many mobile companies such as Oneplus, Realme, Samsung, Xiaomi, many companies are launching their 5G phones in India.

Let us know that when 5G arrives in India, we will get to see which problems.

So first of all, If we see 5G state in India, so spectrum has not been allocated yet.

That is, the spectrum which is auctioned like 2G, 3G and 4G was done, 5G has not been done yet.

And it will be auctioned by the end of 2020.

Then companies will rollout slowly and it will take one and half years to roll out companies.

This means that you do not understand that only after roll out, we will get to see 5G in India, it is not like that at all.

First there will be auction, then testing will be done, after that all the setup will be done gradually and by doing this all will take time till 2021-2022.

So do not expect that we will see 5G very soon in india.

So if 5G comes to India then another problem is going to happen with it.

You get exactly two standards of 5g.

1. Sub-6 Gigahertz
2. Millimeter wave

Sub-6 gigahertz

First, let's talk about the Sub-6 Gigahertz.

The Sub-6 gigahertz has the good thing is that its range is good and the bad thing is that its speed is slightly more than 4G.

You will not be able to enjoy the speed like 1Gbps in Sub-6 gigahertz.

And there is a lot of chance that if 5G roll out in India, then you will get to see Sub-6 gigahertz.

Millimeter waves

If you talk about the millimeter wave, you will be able to enjoy the speed of 1Gbps comfortably, but the problem is that companies are going to face a lot of difficulties in rolling it out in India.

The range of the millimeter is very low, meaning if you want a speed of 1Gbps then companies will have to put 5G towers on every corners of streets.

And so their signals are so weak if you come inside the house and you have a wall in front of you then you will not be able to enjoy the speed of 1Gbps.

So you can understand that within millimeter waves you get good speed but there is an issue of range and quality of signal.

For example, 5G is also available in USA, but americans gets 5G with Sub-6 gigahertz.

High speed 5G will take 4-5 years to arrive in India.

Is 5G radiation are harmful for health?

You must have heard so much that our health is threatened by 5G radiation.

Let us know how much truth is there in this talk.

In 5g, if we talk about millimeter waves, yes their frequency is very high.

And after hearing this, everyone feels that 5G is very dangerous and they often point at the report that came out of IARC (International Agency Research for Cancer).

In 2011, They had classified the Radio Frequency Based Electromagnetic field that is possibly carcenogenic.

Image source-Google|image by IARC

Now this possibly defination of the word which IARC itself says that it has limited evidence or has inadequate information about it.

And so to speak, possibly means keeping your safe side.

Talking about carcenogenic, the IARC has also reported such a report of the coffee you drink daily.

As you can see in the image, the radio frequency comes in Non-Ionizing Radiation, which does not harm us in any way.

But Ionizing Radiation like UV rays can harm our body, UV rays can change our DNA and give us cancer.

So it could not prove that 5G radiation is harmful for our health.

Conclusion

Majority of people didin't have good experience with 4G network.But 5G has no awareness of when companies will set up their spectrum and bands and when they will implement this .

But in India, we will set up Sub-6 5G for the network. In which we will get better range but the speed will be 50-60%better than 4G.

And another problem will be data plans because after coming 5G we will have to pay more to use 5G technologies.

So, what will 5G Technology look like in the coming times and what will be the changes in our lives.
