 What is 5G? 5 Techniques, Advantages and Challenges

Author: Tushar K. Kapoor

5G is being discussed for the last about 3 years and now it has started being used in many countries.

We have arrived in the year 2021 and it is 5G round! 5G is being discussed for the last about 3 years and now it has started to be used in countries like China, America, Japan and even South Korea. As soon as 5G is discussed, we start talking about things like automatic trains, augmented reality and Internet of things.

5G

During the discussion on 5G, 90% of the people will definitely be curious to know what 5G Technology is after all and how it will make space between the existing technology. So I will let's try to explain it to you.

What is 5G? What is 5G?

 

5G is the 5th Generation of Mobile Network. we can think of 5G in such a way that 101 times the faster speed of 4G network. Like 4G, 5G is based on the same Mobile Network Principles.

5th Generation's wireless technology is capable of delivering ultra low latency (signal speed between your phone and tower) and Multi-GBPS Data Speed.

It is a software based network, which is known as Speed ​​and working capacity of Wireless Network.

 Has been developed to increase. This technique also increases the data quantity, which can be transmitted to the wireless network.

5. Full duplex

5th base of 5G Technology

 

The 5G generation is capable of operating in the "sub-6 band", whose frequency is usually between 3Ghz-6Ghz. Most existing Divice like mobile, tablet and laptop also work in this frequency.

Due to a lot of traffic in this system, now thinking of doing experiments above research 6Ghz. He is set to work on 24Ghz-300Ghz spectrum which is considered high-band. export It is also called millimetre-wave (mmWave).

5G Millimeter-wave

Millimetre-wave 5G aquire a lot of data, which makes data transfar possible with a speed of 1 GB per second. Such technologies are currently being used in the US by telecom operators such as verizon and AT&T.

Speed ​​sales

The second base of 5G Technology is speed sales. The Milimeterwave has problems with the range that Speed ​​Sales makes up for. Since mm wave cannot work in interruptions, a large number of mini cell towers are installed throughout the area to relay signals from the main cell tower. These small cells are placed at a shorter distance than traditional towers so that users can get 5G signal without any interruption.

Maximum MIMO

The next premise of 5G Technology is Maximum MIMO, ie multiple-input and multiple output technology. Using this technology, large cell towers are used to manage traffic. A regular sales tower that provides 4G network comes with 12 antina that handle Cellulor traffic in that area.

.

MIMO 100 can support the antenna simultaneously which increases the tower's ability if there is more traffic. With the help of this technology, it helps to deliver 5G signal easily.

Beamforming Beamforming

 

Beamforming is a technique that can continuously monitor multiple frequencies and switch to another strong and high speed tower when one signal is blocked. This make sure that the particular data only goes in a particular direction.

Full duplex full duplex

Full duplex is a technique that helps to simultaneously transmit and receive data in the same frequency band. Such technology is used in Landline Telephone and Short Wave Radio. It is like a two-way street, which sends the same data from both sides.

Benefits of 5G Technology

 

Think that you have downloaded a full HD movie within 3 seconds. According to 5G Network qualcomm, 5G is capable of giving 20 GB per second speed in traffic capacity and network efficiency.

Also with mm wave, you can get latency of 1ms which helps to establish instant connection and reduce network traffic.

Qualcomm Chairman Cristiano Amon also believes that 5G will give network speed, which can make Augmented Realty experience in Real Time. This will also help in the development of hardware working on Augmented Realty.

This technology is going to be the basis for virtual realty, automatic driving and Internet of things. This is not only going to improve the experience of using your Smartphone, but will also help in the development of medical, infrastructure and even manufacturing.

5G Challenges

 

Bringing 5G Technology is going to be very expensive. Network operators will have to remove the existing system as it requires more than 3.5Ghz Qualcomm which is bigger bandwidth than used in 3G or 4G.

The bandwidth of the Sub-6 Ghz spectrum is also limited, so its speed can be less than the millimeter-wave.

In addition, the MM-wave is more effective in short distances and may not work in obstructions. It can also be Absorb through trees and during rain, which means that you will need to install a lot of hardware to implement 5G in a concrete way.

The expansion of 5G has been but not according to the expectations of the people. According to GSMA Intelligence report, even under the current rate, 5G will not be able to overtake 3G and 4G by 2025.

5G

However, President of Qualcomm Cristiano Amon believes that by 2022 the number of 5G smartphones will be 80 crore and by 2023 the 5G connection should be 1 billion. It has taken more than 2 years for 4G to reach this figure.

Apart from this, there is also issue of  the security and privacy with 5G technology, which will be known only after more use.

Can 5G work with 4G?

 

5G works better at frequencies of spectrum over 6Ghz. Older technologies like 2G, 3G and 4G also operat on wireless bands which range between 3.5Ghz to 6Ghz.

According to a report by Android Central - 5G can work with 4G but 3Ghz-6Ghz spectrum is being used on short mm wave between 30Ghz-300Ghz ahead of research 6Ghz due to more usage.

Such spectrum was previously used for technology but was never used for mobile divice. Going into this spectrum means getting more bandwidth for mobile devices.

Some technologies like 5G NR (New Radio) and even 5G (AT&T

Proprietary LTE Advanced Network) works on 4G networks, but they are not as fast as mm wave, which means new hardware will have to be installed for speeds above 1 GB per second.
