4G network is slowing down. That is why now 5G is being prepared. Let us know how 5G is different from 4G and what this network can do. Internet browsing started with 3G network in mobile phones. Websites started being opened on mobile, the map also started appearing. The world of 2G networks filled with SMS slowly started to end. With the development of new and high-speed processing chips, the expansion of optical fiber networks and wireless networks came the fourth generation or 4G network.
It was a technological leap. High speed data started coming in smartphones and tablets without any wires. Due to the fast data speed, the use of apps for navigation, messaging and many other things started. Videos also started watching comfortably on mobile phones. The average speed recorded on the fastest 4G network is 45 Mbps (Megabits per second). The industry had hoped that this could be increased further, but due to the increasing demand for smartphones across the world, 4G networks are now becoming a victim of overload. This can be understood in such a way that a single vehicle on the highway can speed up, but if there are 1,000 more vehicles on the road then the speed will slow down.
5G is a preparation to solve this problem. Chip makers expect internet speeds to be up to 1,000 bps in 5G networks. In common life, this would mean that 10 to 20 times faster data download speed than 4G. 5G is also being called a confluence of five different technologies.
These include Millimeter Webs, Small Cell, Massive Mimo, Beamforming and Full Duplex. Currently, our smartphones and other electronic devices like TVs or Wi-Fi run on frequencies below 6 GHz. But due to the increasing number of devices using the Internet, this frequency is getting jammed and slowing down. That is why there is now a preparation to use the empty frequency band of 30 to 300 GHz through millimeter webs.
But due to the short wavelength, millimeter webs do not travel very well. They are not able to cross obstacles like trees or buildings. Rain and trees also absorb these waves. That is why small cell technology is also being mixed with it.
At present, tall mobile towers are used for data transfer. If even millimeter webs were released from these towers, they would collide with obstacles and become useless. That is why now there is talk of setting up many small small cell base points around a big tower. These base points will work to spread the frequencies of the high tower like transformers.
Massive Mimo, a technology called multiple input and multiple output, is also being used in 5G. 4G towers have about a dozen ports for antennas. Massive MIMO based stations will have more than 100 ports on the antennas. But so many signals will also have cross connection, so the fourth, beamforming technology will be implemented.
Through this, the signals will be transmitted in the prescribed directions instead of getting confused with each other. Full dupe technology will handle incoming and outgoing data simultaneously. This is a very high tech technical confluence. Its effect will be directly visible in the form of very fast wireless network.
Full HD movie will be downloaded within few seconds. But the use of 5G is much wider than watching videos on a smartphone. With its help, driverless transport, smart cities, virtual reality and very fast real time updates will be available. 5G is a technology based on interconnected signals.
Through this, one vehicle will also communicate with the other vehicle and will decide through the data what should be the distance and speed between the two vehicles. 4G network feels weak in terms of 3D data. 5G will also make live changes in 3D data. Let's say you are wearing some virtual reality glasses that are showing you a virtual box.

With a 5G network, you can rotate, open, cut, and detach or change the walls of that box in real time, all these changes in front of you in real time. But with the 5G network, many concerns are also coming to the fore. This network will especially make cities a network of millimeter webs. Its adverse effects on insects and birds are also being feared. In some health-related research, it is being claimed that 5G will also damage human cells and DNA. But amidst these fears, some countries of the world including China are going to launch 5G network. Only after use will the technical, health and environmental problems related to it come out accurately.
