5G network in India is going to take over the market of 4G network till 2020. Already it has been implemented in different countries and peoples are enjoying it. As per their experience, 5G network will revolutionize the whole communication industry in the future.
What is 5G network?
Every new generation wireless network provides the fastest communication speed and more functionality through our phone.
1G brought up a very first cell phone, 2G let us text the first time, 3G allowed us to come online and 4G provided the fastest speed of communication or delivery of message.
But as more users come online 4G network reached on its limit and the speed of the internet has gone slow and slow day by day.
And now we are headed with 5G which is the next generation wireless technology with high speed and more functionality. It has a higher frequency range and high speed internet connection than 4G.
It is 10x times faster than 4G.
Because it’s has a bigger capacity than 4G so it can connect thousands of devices at the same time in a small area.
And if all goes well, one day it will end up the use of Wifi.
5G network in India and in other countries is going to be a game changer in the future. Let’s see which telecom company can take the advantage of 5G network in India.
Technology used in 5G
There are five brand new technologies that are emerging as a foundation of 5G network.
Devices around us or at our home are using a very specific frequency on the radio frequency spectrum and those frequencies are typically 6 Ghz.
And these frequencies started getting more crowded. As more devices come online it started getting more traffic and slower services.
So research experimenting with broadcasting on millimeter waves. Millimeter frequency falls between 30 to 300GHz. This section of the spectrum has never been used before for mobile and other devices. Opening it means having more bandwidth and high speed for everyone.
But there is an issue that millimeter-wave can’t travel through buildings or other obstacles and they tend to be absorbed by plants.
And to solve this problem we need technology number second small cells.
2. Small cells
Today’s wireless network relies on high powered towers to broadcast their signals over long distances.
But remember having higher frequency millimeter waves have a harder time to travel through buildings or any other obstacles which means if you move behind the one you lose the signal.
And this problem can be solved by using low power mini base stations. These towers would be much closer than traditional tower forming.
This would be more helpful in cities.
3. Massive MIMO
MIMO stands for multiple input and multiple outputs.
Today’s 4G base stations have dozen of ports for antennas that handle all cellular traffic. But today’s massive MIMO base stations contain 100th of ports which increase the capacity of today’s network.
Massive MIMO also has its own complication, today’s cellular antennas broadcasts in every direction at once and all of them are crossing signals which could be a serious problem and this problem will be solved by our fourth technology Beamforming.
4. Beam forming
Beam forming is like a traffic signaling system which allows antennas to broadcast signals in a specific direction instead broadcasting in all direction.
Suppose, you are in a cluster of buildings and trying to make a phone call and the signals around you are criss-ss crossing each other, here a massive MIMO technology-based station will receive all the signals and keep track of the timing and direction of their arrival.
Then, by using a signal processing algorithm it specifies where the signal is coming from and sends the signal back to that specific user phone.
It has also its complexities, sometimes it bounce individual data packet in all directions and as a result, we get coherent of data packet and to solve this problem we will use our 5th technology which is full duplex.
5. Full duplex
Suppose, a train loaded with the data running on a track and another train is coming in its opposite direction so here it’s going to get interference. In the same way, when incoming and outgoing data is passing through a single frequency it gets interference. But fu duplex allows to send and receive data on a different frequency and end up the problem of inherent complexities.
Now it’s time for the world to move from 4G network to high speed 5G network. Already many countries like United States, South Korea, and others are using 5G technologies. But in India still it is not launched. As per the plan of government and telecom companies 5g network will be soon in India. 5g network is on the way with the revolution of the communication industry and the experience of mobile phone users.
World has been entered in the era of the internet of things where it needs high speed internet connectivity with the capacity of more device connections.
The future of wireless communication
As 5g network is in the way so you can imagine what can be the future of India. Before discussing the future of 5g let’s go a few years back when 1G was launched and brought up with the first cellular phone, then 2G came with text message features, 3G allowed users to come online, and in last 4G which was the fastest internet speed in their coming days but nowadays as more users are coming online so 4G has reached on its limit.
And to overcome the problem of 5G will be in the market with 10 times faster and more functionality than 4G. And now finally 5G has been launched in other countries and in few days it will be India too. It has 4 times higher speed than 4G network.
5G wireless network has been revolutionized the mobile experience of user.
5G network is not going to limited only to mobile communication, it’s the world of IOT where communication is happening between objects too.
High speed internet
5G network provides high bandwidth internet ranging from 4GB to 10GB. Compare to previous networks like 4G, it provides many times higher than that. 5G network in India of course in other countries also will revolutionize the mobile experience of users with a high speed. Till now we have download and uploaded data at the speed of megabytes and never imagined that in the future somewhere a gb of data will upload and download in a second but 5G technology proves us wrong.
Researchers predict that the maximum internet users are using the internet for uploading and downloading songs, videos games etc. 5G network will be the first highest uploading and downloading speed provider in the communication industry.
5G provides the high speed internet that will help users to access cloud systems easily. The gamer who doesn’t have a high configuration computer 5G will provide them facility to play games virtually on a cloud system without getting any interruption.
Internet of things
Till now only peoples are communicating with each other but in future with the help of IOT objects will communicate with each other. So before entering the era of IOT we need high-speed internet connection that does not interrupt the communication between things and 5G network provide this requirement.
Internet of things device will take more advantage of 5G network.
Smart home and cities
The concept of smart homes and cities specifies the use of 5G technology by connecting the devices and monitoring the applications.
5G technology will be utilized by smart appliances which can be configured and monitor to access from the remote location like ‘on and off the security camera for security reasons and more.
The use of 5G technology in smart farming can be checking the moisturization level of field using the IOT devices.
A car having no driver but driven with the help of internet where each car and vehicles will communicate with each others. 5G technology provides them high speed internet connection to have no interruption in communication between them.
- Peak data rate of 5G network is 20GB downlink and 10 GB uplink.
- 5G must support 1 million connected user per kilometer.
- Experienced data rate of 5G network is 100Mbit/s.
- Latency is 1ms.
- Mobility means maximum speed of handoff which is 500km/h.
- Connection density – total number of devices per unit area is 106/km2.
When will be 5G network in India?
Till now no one has announced the fixed date of launching 5G network in India but companies like Jio, Airtel, Vodafone are designing the infrastructure of 5G network. 5G technology has higher frequency band and more functionality so it is not able to work on the 4G infrastructure.
5G network has 10 times higher bandwidth than 4G network. 5G is the first wireless network that has the capability of competing with fiber optic cables. And this has been possible only because of millimeter wave technology which provides higher frequency bandwidth.
5G network in India is going to be a game-changer in the future with its high-speed internet connection.
