What is 5G?
5G is the fifth generation of mobile network technology which provides unique features over the previous generations.
3 Key features (technical goals) of 5G:
1) Enhanced Mobile Broadband (High-Speed Internet)
2) Massive Machine to Machine type Communication
3) Ultra-Reliable and Low latency Communication
These three features will enable new applications and service areas like
1) Internet of Things (IoT)
2) Smart Home/ Smart Cities / Smart Agriculture
3) AR/VR based services
4) Cloud-based Gaming services
5) Autonomous vehicles (Self Driving Cars with very high reliability)
6) Smart Industries
5G frequency bands:
5G technology supports two frequency bands
FR1 : 410 MHz to 7125 MHz (sub 6GHz)
FR2: 24.25 GHz to 52.6 GHz ( mm-wave Band)
* mm-wave frequencies start from 30 GHz, but as 5G frequencies also cover beyond 30 GHz frequencies, it is commonly called as mm-wave band.
Key Technologies behind 5G
1) Massive MIMO
The 5G radios will support an array of antennas, which will increase the reliability, high throughput to end-user, and high spectral efficiency.
2) Network Slicing:
Network Function Virtualization (NFV) enables the network Slicing, where there will be multiple logical networks on top of the physical shared infrastructure.
Different types of services like IoT, low latency communication, high-speed internet can be served on these different logical networks.
Standalone and Non-Standalone 5G
Currently, there are two possible deployment options for 5G.
1) Non-Standalone 5G:
In this deployment, 5G New Radios (NR) will be used to serve High-Speed Data and Voice to users but for control and signaling 4G LTE architecture will be used.
With non-standalone 5G will enable the fast deployment of 5G as existing LTE infrastructure will be used for 5G deployment.
2) Standalone 5G:
In standalone 5G, NR as well the core architecture is 5G.
Standalone 5G will enable the true 5G experience for consumers.
This video will be helpful to everyone in understanding what is 5G and how 5G works?

They are hiding 5 G in my old schools playground so the students can get cancer. Yes they did put a 5 G tower inside the playground poles you can easily tell.
INSECT BITE *-* I guess you’re going to tell me the Earth is flat to 4Weird
@@van7915 my step dad can see 5 G from space. He tried to be an astronaut but he failed because he admitted that he hated their deep state 5 G population controll plans. Ever since my step dad have been preparing for disaster. You need to fight back.
INSECT BITE *-* sure dude

Sir best explanation....
Great content!
Thank you, very nice explanation. Is English your native language or did you learn it as a secondary language?
No, its a secondary language.
Great lecture
Keep going keep growing
the best video on 5g
The conection easy fast tô machines of 5g in the wold off 3g
Sir please make videos on Iot..
I have been using 5G for almost a year, and its speed is much faster than 4G. The download speed is about 30M/s
Is 5g penetrate through amber glass a inch away? Also... When you 5g phone screen is off ....is it still emitting high amount of 5g?
What these 700MHz 800Mhz 1800MHz 3300MHz ad 26GHz represents ? Can you please explain about it and difference with respect to other
Can u explain this 5G frequency does it affects the brain if we were to hold the handphone to our brains.
In satellite communication we usually prefer uplink frequency greater than downlink frequency..but in 5g mobile technology y uplink less than downlink...can u explain this?
In mobile communication, in the up-link, the data is transmitted from mobile device to base station. To preserve the battery of mobile device, the lower up-link frequency is used. (As frequency increases, the attenuation increases. And therefore, more power is required to transmit the data at higher frequency). In case of the satellite communication, the up-link is the data transmission from base station to satellite. And down-link is a data transmission from satellite to base station. To preserve the satellite power, downlink frequency is lower in satellite communication. And since the base station can afford to provide more power, up-link frequency is higher. I hope, it will clear your doubt.
@@ALLABOUTELECTRONICS thank u sir
Nice
Can you make a video on how well a world leader can control their machines all over the world, like in a war situation
Bro which course did u studied bro 😎
What about band 2, band 13....
Nice clip ♥♥! As a fellow TH-camr, I am always looking for creative ideas! Great Job!
So Samsung or any other 5g phone is not standalone 5g, is that correct?? They are 4g phone but can connect to 5g base station
When we say it is 5G phone, It means supports 5G frequency bands along with 4G bands. But as I said, there are three frequency bands for 5G. And in different countries different 5G frequency bands have auctioned so far.
So, if you see the network specification of any smartphone, then some numbers are mentioned.
e.g for Samsung galaxy s20 ultra : 5G bands are 2, 5, 41, 66, 71, 260, 261 SA/NSA/Sub6/mmWave - SM-G988U
e.g 71 means 600 MHz, or 260 is mm-wave (39 GHz).
While selecting 5G phone, one needs to check whether the smartphone supports the 5G bands of a particular country or not.
I hope it will clear your doubt.

Explain VSLI
DoD already used up a big part of the 5G MMW frequencies (spectrum allocation for 5G), leaving less commercial use. The excerpt below explains why the U.S. is still struggling with 5G in terms of implementation. According to the National Security Implications of Fifth Generation (5G) Mobile Technologies document and excerpt to find out why the U.S. is still behind with 5G in building up capacity.
("The Department of Defense (DOD), however, holds large portions of the usable spectrum. Although DOD uses certain MMW frequencies for high-profile military applications such as Advanced Extremely High-Frequency satellites that provide assured global communications for U.S. forces, it extensively uses sub-6 frequencies-leaving less sub-6 availability in the United States than in other countries. The Defense Innovation Board (DIB) advised DOD to consider sharing sub-6 spectrum to facilitate the build-out of 5G networks and the development of 5G technologies used in the sub-6 band. While DOD has been moving toward greater spectrum sharing, it has expressed concern that sharing presents operational, interference, and security issues for DOD users. As an alternative to spectrum sharing, some analysts have argued that portions of the sub-6 spectrum should be reserved for commercial use. This would require DOD to relocate certain applications to other parts of the spectrum. The DIB estimates this approach would take around 10 years to complete, as opposed to 5 years for spectrum sharing.")
I can make animations for you
Sir what should we do to prevent hacking of our computer 🙏🏼
You can follow these steps.
1. Regularly update Pc with the OS security updates
2. Never click on phishing links sent via mail
3. Do not save password in browser
4. Keep firewall always ON
5. Avoid using pirated softwares
@@ALLABOUTELECTRONICS thank you sir love you very much I'm very lucky that you replied me ❤️❤️
Frequency of what ?? What vibrates 6 Hz
What's mimo?
As, I mentioned in the video, the MIMO stands for multiple input, multiple output. Means both transmitter and receiver contains multiple antennas. It adds the spatial diversity. Meaning using the same frequency, the same data can be sent to the receiver using two spatial paths. It reduces the data error rate. And increases the data speed.
Its also possible to implement spatial multiplexing with MIMO, where different set of data is sent to the user using two different spatial paths. It improves the end user throughput.
Actually a very good explaination.
Very good content but the reader's accent and pentameter gets in the way a bit.
Maybe get a smokin' hawt babe to read the same thing?
5G comes with FDD or TDD
Will we be able to change our 4G infrastructure by the time 6G comes?
6G will take time. Even to experience a true sense of 5G in our country, a lot of infrastructure needs to be changed.
What is the negative effects of 5g?
Please also describe. Technology is improving day by day and ecosystem is also destroying proportionatly.
Humans basically needs pure environment than improved technology. The greedyness of humans will destroy himself one day.
The one myth about 5G is that, it can harmful to the humans.
But there is no conclusive scientific evidence about that.
Speaking more scientifically, the radio waves in 5G is coming in non-ionizing radio bands, (unlike X-ray, UV- rays and Gamma rays, which are ionizing waves). These Ionizing waves can knock out the electrons from the atom and can ionize the atom and molecules.
when human body comes in contact with such waves, it can harm us. And can cause serious problems if it is beyond certain limit.
But that's not the case with 5G or any radio waves which we are using in telecom currently.
Even current WiFi bands are also using frequencies in the same range. (5 GHz wifi)
At the most, these waves can penetrate human body an can increase the body temperature fractionally. The increase in temperature will be very low. In fact, our body is accommodating that much rise in temperature when we do exercise or any physical activity.
So, as far as the power of such waves is less than threshold they won't cause any harm.
Of course the number of base stations will increase in 5G, but the power level of each transmitter station is very
low compared to power of existing transmitters using in current generation. And the power reduces as per the square law with the distance.
In fact, most of us are using wifi routers at home. which has similar frequency and power level.
So, long story short, as of now, there is no evidence of any harmful effect of 5G on human begins.
And scientific community is continuously doing research to find any adverse effect of it on our body.
