What is the difference between 4G and 5G

The telecom industry bandwidth has travelled a very long distance, so do the internet connection speed. It was started from 1G back in the 1980s to underdeveloping 5G technology. There has been a lot of telecom companies pouring millions of money for developing this future technology. What is so special about this technology which is attracting so much of effort and money and how current 4G technology is better than ongoing 5G technology? What is the basic difference between 4G and 5G ?

Before going deep into the 5G technology let us first understand how and when this all started. We all have heard of 1G,2G, 3G, 4G & 5G. 

“G” stands for Generation whereas number (1,2,3,4,5) indicates the technological improvements. Roughly every subsequent generation has developed in 10 years. With each generation change internet speed increases, for ex- 1G offers 2.4 kbps, 2G offers 64 kbps and is based on GSM, 3G offers 144kbps to 2Mbps, 4G offers 100Mbps to 1Gbps(based on LTE technology). 5G is expected to offer internet speed 10 times faster than 4G.

How 4G developed & evolved ?

The 4G technology started in 2000, and it’s nearly 10 years after we are going to witness 5G. However, for developing countries like India, 4G came very late but reached to the maximum population in a short period, thanks to JIO for free benefits. 4G made mobile internet speed 500 times faster than 3G and allowed video call, HD & 4K video steaming, much faster browsing. 4G made IP telephony, HD mobile TV, 3D television, Online gaming services & cloud computing accessible to the broader population. There is a remarkable contribution of 4G in developing modern smartphones and tablets.

MIMO(multiple input multiple output) and OFDM(Orthogonal frequency division multiplexing) are the two key technologies which have made 4G technology possible. The internet speed what we experience now is 100Mbps to 1Gbps, but in the beginning, 4G speed was only a little faster than 3G. Over the time 4G has evolved into 4G LTE(long term evolution) so, basically 4G LTE is the evolved version of the primitive 4G technology. It has significantly reduced the latency from 300ms to lower than 100ms. Lower latency has boosted online gaming all over the world.


Now the Internet of things is real future; cloud service connects everything and internet users are increasing at an exponential rate. Moreover, the current 4G network is unable to handle this increasing demand for high-speed Internet. That is where 5G comes into the picture.

How 5G is different ?

5G is currently under development and expected to be faster, smarter & more efficient than 4G. The significant change might be the shallow latency rate apart from significantly higher data speed and connection density. It will provide a more significant boost to the internet of things which is going to impact significantly future business.

Reduced latency means smoother communication and ultimately streamline online games. 4K video can be played straight away without buffering. It will easily handle a large number of users without network speed drop. Moreover, large files can be downloaded without any connection crash. You wouldn’t have to worry about connecting many smart devices altogether. The maximum speed of 5G is expected to be 10 times of 4G.

However, we must remember that many of the this discussed are still theoretical. There is much hype about 5G in the market, but time will reveal the truth. To make 5G a reality, government and telecom companies will have to invest a lot to build the infrastructure. There is also a significant security aspect involved in 5G. If everything went fine, then we can expect it to be launched by 2020.

I Love technology and the way it is transforming our lives, call me a geek!! Apart from that, I spend my time playing games, watching movies & most importantly the Painting. Reading books is one of my best sources of inspiration.
