How does 5G work?
5G means the 5th generation (fifth generation) of mobile networks. This is actually a very important development of today's 4G LTE network. 5G is primarily designed keeping in mind the needs of today's times. Since there has been a huge increase in data and connectivity of today's modern society, it has been designed to fulfill it.
What's more, it has been modernized enough to connect the Internet of Things with billions of connected devices, and to go hand in hand with the innovations of tomorrow. While 5G will initially work in conjunction with existing 4G networks, it will later develop into a completely standalone network.
What is 5G?
5G is actually the 5th generation mobile network. It is a new global wireless standard that is also followed by 1G, 2G, 3G, and 4G networks. 5G enables a new type of network that is designed to connect almost everyone and everything together, including machines, objects, and equipment.
The basic purpose of 5G wireless technology is to provide higher multi-Gbps peak data speeds, ultra-low latency, greater reliability, massive network capacity, increased availability, and a similar user experience for more users. Higher performance and improved efficiency empower new user experiences and connect new industries.
How does 5G network work?
As wireless communications systems use radio frequencies (also called spectrum) to carry information through the air. In the same way, 5G also operates, but in this it uses higher radio frequencies which are much less chaotic.
This meant that, very easily, more information could be transferred at a faster rate. These higher bands are called 'millimeter waves' (mmwaves). While these were not used earlier, they have now been opened up for license by the regulators. Their use was often impossible for the general public because to use it required such equipment which is largely inaccessible and costly.
When higher bands are used, which are much faster in carrying information, there may be problems when this data is sent over long distances. These signals can be easily blocked by trees and tall buildings. So to overcome such a problem, 5G uses multiple input and output antennae, which makes it easier to boost signals and increase capacity across wireless networks.
Small transmitters are used in this technology. They are placed in buildings and on street decorations, in place of single stand-alone masts. Current estimates say that 5G will be able to support 1,000 more devices per meter than 4G.
5G technology is also capable of 'slicing' a physical network into multiple virtual networks. This means that the operator can very easily deliver the right slices of the network, depending on how they are going to be used, and then better manage their network accordingly. Is.
This means, for example, that an operator will be able to use different slice capabilities based on importance. Therefore, a single user streaming a video will use a separate slice for business, while simpler devices can be separated from more complex and demanding applications, such as controlling autonomous vehicles.
There are also plans to allow businesses to rent their own isolated and insulated network slices to isolate them from competing Internet traffic.
Who invented 5G?
Neither person nor any company invented 5G technology. By the way, there is no such scientist who himself invented 5G network. Many scientists have a hand in this, who are associated with different nations. But yes, the first country to adopt mass adoption was South Korea, which started using 5G network in April 2019. At that time there were about 224 operators in 88 countries around the world that were investing in this technology.
In South Korea, all 5G carriers used Samsung, Ericsson and Nokia base stations and equipment. At the same time, only one used Huawei equipment. Among these suppliers, Samsung was the largest, having shipped 53,000 base stations out of a total of 86,000 base stations installed in the country at the time.
There are currently nine companies that sell 5G radio hardware and systems to carriers. These are Altiostar, Cisco Systems, Datang Telecom, Ericsson, Huawei, Nokia, Qualcomm, Samsung and ZTE.
How Fast is 5G Compared to 4G and 3G?
If indeed 5G reaches its full data speed, then its speed will be around 10 Gps, which will be about 100 times more than standard 4G. It will also be 30 times faster than advanced 4G standards like LTE-A. In this way, it will easily outperform both 3G and 4G.
Where 3G has an average download speed of 384Kbps and a maximum of 8Mbps, while 4G has an average download speed of 32.5MBps, the maximum can go up to 100Mbps. 4G+ averages 42Mbps and maximum download speed is 300Mbps. Whereas 5G, by comparison, has an average download speed of 130-240Mbps and a theoretical maximum of 1-10Gbps.
This means, for example, that it will take 4 to 40 seconds to download a Full HD movie on 5G, while it will take more than 7 minutes on 4G and a day longer with 3G.
Where is 5G used?
Primarily, 5G is going to be used the most in three places. That includes enhanced mobile broadband, mission-critical communications, and massive IoT. A defining capability of 5G is that it is designed for forward compatibility – the ability to flexibly support future services that are unknown today. Which shows that 5G is going to be the root of many new technologies going forward.
Enhanced Mobile Broadband
Along with improving our smartphones, 5G mobile technology is also going to provide users with a whole new experience like VR and AR with faster, more uniform data rates, lower latency and lower cost-per-bit etc. with.
Mission-Critical Communications
5G can very easily enable new services that have the power to transform industries in the long run, in highly-reliable, accessible, low-latency links such as critical infrastructure, vehicles and medical procedures, etc.
Massive IoT
5G simply means connecting embedded sensors on a large scale with great ease and that too virtually. With this, it can easily reduce data rates, power and mobility. Lastly, it provides you with a very lean and low cost connectivity solution.
What did you learn today?
I hope you must have liked my article on how 5G works. After reading this, you must have easily understood what 5G is. It has always been my endeavor to provide complete information to the readers about the complete information of 5G in Hindi, so that they do not have to search any other sites or internet in the context of that article.
This will also save their time and they will also get all the information in one place. If you have any doubts about this article or you want that there should be some improvement in it, then you can write low comments for this.
