What is 5G? What’s so special about 5G?

The hype of the 5G network has already started. All of the telecom carrier companies across the world are announcing the launch date of 5G. As a matter of fact, 5G is coming and is sure to change how we experience technology and interaction with different gadgets.

Time is taken to download two-hour-long movies in 3G, 4G, and 5G.

The 5G is basically a software-defined network based on the cloud. The 5G is going to be much faster than its predecessors 3G and 4G. It will have 100 times more capacity than 4G. This is going to drastically improve our current internet speed. For example, to download a two-hour-long movie, it will be taking 26 hours on 3G and 6 minutes in 4G whereas in 5G it will be taking 3.6 seconds only. This sounds incredibly fast, right? Besides internet speed, the response time will also be faster in 5G.

1G started the usage of very first cell phones.2G allows us to do texting for the very first time.3G brought us to this vast internet.4G made everything faster and content access and delivery on the internet faster. As the number of online users has reached billions, 4G how now reached its threshold of data traffic. Now, 5G is the new foundation for all our recent trending topics that the internet is filled with like VR, IoT, Autonomous driving hologram projection, and all the others.

5G is basically based upon five major foundations.


2. Small Cell Technology

3. Massive MIMO(Multiple Input, Multiple Output)

4. Beamforming

5. Full Duplex

5G Foundations

5G is going to have a very low latency rate, that is the amount of delay between sending and receiving of data is going to be a bare minimum. For 4G its about 100-200 ms. But 5G will offer the latency as low as 1ms which is much lower than human reaction time which is 200 ms.

5G Latency as compared to 4G and human reaction time

The data rate will be 20 Gbps on 5G as compared to 4G which gives the data rate of 10-20Mbps. Moreover, the response time will be 0.001s for 5G which is much lower than 4G which has a response time of 0.045 seconds.

Response time comparison between 4G and 5G

It will allow to interact with people and object on real-time, virtually no lag. For example, the surgery could be performed from a remote location in real-time using a robotic hand without any delay.

The major boon will be for an autonomous vehicle which will require a continuous stream of data to be transmitted. Nevermind, for internet gaming, it will be a game-changer as well, Imagine playing Fortnite and PUBG in VR headset in real-time with zero lag.

Frequency spectrum used in 3G/4G vs 5G

5G uses a millimeter-wave that has a shorter wavelength and high frequency.
5G uses the frequency ranging from 1G Hz up to 70 GHz.This means, more transmitters required every 100m.

5G radio wave as compared to other waves in the frequency spectrum

The risk of 5G  to human health is yet to determined. As a matter of fact, no real test has been done to the impact of wireless radion on human health. Research done in China has pointed out of carcinogenic impact on the human brain and can be a carcinogenic impact on brain tumors and cancer.

To have the heating impact on the human body due to radiation, the frequency must be at the range of million GHz.

No ‘good’ evidence has not been determined and no major research has been done on this matter. However, absence of evidence is not evidence of absence

Albeit, 5G is going to be a game-changer and drastically optimize our wireless experience .Sit tight and enjoy the technology ride.
