5G is the next generation of wireless technology that will transform our life significantly. 5G is the successor of 1G, 2G, 3G and 4G networks. 4G was faster than 3G which was faster than 2G, so you will think 5G is just about speed. But no, it isn’t just speed, it is beyond that. Surely 5G is much faster than 4G. But other than speed, 5G addresses the evolution beyond mobile internet to massive IoT (Internet of Things) ecosystem. In this article, we will discuss these topics in detail.
5G brings mainly three new specifications:
Speed: 5G brings a faster connection speed that means higher data transfer in less time. 5G has a peak speed of 20 Gbps as compared to the 1 Gbps speed of 4G.
Low latency: 5G offers very low latency i.e., the delay between sending and receiving information. 5G will take only 1 millisecond response time as compared to 4G which takes 100 milliseconds response time.
More bandwidth: 5G can support more devices and allow simultaneous data transfer. In 1 square kilometre, 5G can support 1 million devices which are 10 times more than 4G.
Other benefits include:
Users will enjoy uninterrupted streaming.
IoT (Internet of Things) is the area that will be developed using the 5G network. IoT will connect every object, device, sensor to the internet.
Self-driving vehicles are one of the most desired applications of 5G. Due to very low latency, vehicles will automatically respond to objects and changes around them.
5G will develop city infrastructures like traffic monitoring, crowd management, and emergency response.
Doctors will be able to perform remote surgery virtually with no lag time.
What makes 5G faster?
The 5G network is built on high-frequency airwaves. 5G uses radio frequencies in sub 6 bands from 600 MHz to 6 GHz. 5G can also use a higher band of radio frequencies from 24 GHz to 86 GHz. These higher frequencies bring with them higher data rates. But these 5G radio waves can’t carry data very far. Shorter wavelengths carry more data but are easily blocked by trees and walls. So, the transmitters need to be closer. 5G uses small cells which are small versions of big cell towers. These small cells have a range of 10 meters to a few kilometres.
5G and Global Economy
5G will boost the world economy. It is estimated that 5G will add $1.3 trillion to global GDP by 2030. It will create 22.8 million new jobs.

As of now, 224 operators have launched 5G services in 88 countries that are in the testing phase or have been licensed to conduct trials. In April 2019, South Korea was the first country to adopt 5G. It is estimated that by the end of 2025, 5G will cover 65% of the world population. In March 2020, the first 5G smartphone Samsung Galaxy S20 was released.
Concerns about 5G
There is a long history of fear about wireless technology, 5G is not an exception. Concerns are about 5G’s use of microwave frequencies. But microwaves are not new. Our smartphones, wireless headphones, ovens use microwave frequencies. Some experts believe that 5G’s shorter wavelengths are less harmful than the devices we are using now.
There are several conspiracy theories that are linking COVID-19 with 5G. But the fact is, viruses can not travel on radio waves.
So, what do you think about 5G? If you have something to say, please leave a comment.
