People making fun of the video do not see the value in such knowledge, available free for everyone on internet. Hats off to Learn Engineering for the content

You think you know a lot, until you realize you have so much more to learn.

Whoever did the 3D is the reason why i enjoy all of these videos.

I really love this channel. I never even thought to wonder about this technological challenge, but the explanation is fascinating.

I will not skip the Ad as a matter of gratitude for the immense value provided through this video. The channel needs to grow. Money in exchange for incredible animation and informative content..... Basic Economy !!

This channel explains concepts like no other!! Grateful to have such content for free.

Great Videos, It's really a treat to see high-quality explanations of engineering topics!

thank you for everything you do. really appreciate the hard work you put into your content

sir , you are providing a depth knowledge in a very simple manner , thanks alot for that .

Discovered your channel yesterday. Great explanation. This video was better than the course on my university. :D

Wow! Amazing Thank you for making me fall in love with technology even more

I always watch learn engineering videos in my spare time and it's worth learning through it. Always providing knowledge, Keep It Up, Team!!!!

OMG look spectrum of this frequency: 1:53 ! Great video!

Super useful information. Loved it. Thank you man for making this so clear to understand 🙂

great video!! i love the way this channel talks about the physic behind techniques

Nice to see a video that explains what my job helps with on a larger scale. Thanks!

This is great😀! Thanks for the video

This topic is great for me . Thank the creator !

Very informative Video. Thanks a lot !!

What a channel. 100/100 loved it

Wow glad I discovered this channel very informative thanks

Wow what an explanation.love u sir..... Bt How can People dislike it. May be they are "out of the world".

I've been looking for a video that explains this info, but just never knew how to ask it, and glad i found your video!!!!!!!!!! Sorted out a lot of qestions I had

so nicely and precisely explained. thank u for the stuff

i have learned more after watching like 5 of of your videos than months of reading books. the graphics and analogies help tremendously

this is something new to me. thank you for the knowledge.

Such an informative video! Thank you!

Really awesome! I highly appreciate Learn Engineering.

شكرا لكم ،أتمنى لكم الخير والتوفيق ، وأتمنى أن يكون هناك المزيد من الفيديوهات عن علم الإتصالات في قناتكم العربية 🖤

Excelent video! Thank you!

Im learning so much tbh. thank u so much for these videos!!!

This video was very informative, clear and concise. Automatic sub and like!

Explain in such a lucid manner!

Thank you for the knowledge sir.. The 3D animation is great.

Great video. This is exactly what I wanted to know. Thanks!

Engineering milestones described per second is highest of this channel. Adbhut..

Perfect illustration.

Best example given it really helps a lot

Awesome wealth of Knowledge!

Thanks a lot guy This is Great information for me

"These sub-carriers are mathematically orthogonal to each other and each of them are modulated individually. We hope this video gives you a clear understanding about what is spectrum." yep, all clear 🙂 great video. My head is exploding. But I mean it, it's a great video. Thank you

Hats off to Learn Engineering for such a complicated subject made easy to learn. Really.

Excellent Demostration !!

Me and my friend would joke around and call each other's mobiles despite standing next to each other. We would always hear a high excruciating frequency wave , I was always sceptical on why. Now it makes a lot of sense watching this video.

Thanks bro I really love these types of subjects than a boring poem and grammar's , I really love the way of learning by Looking in real life

Very very nice explaination.Thank you sir

Great video! Hope to see more in depth videos about this topic. Thanks!

Damn.... It's hard to comprehend , just imagine that someone made it before that we understood it.

Had always been curious since childhood on how one phone rings amongst many kept together. I think I got the clue today. Thanks! 🙏🤗

I worked on LTE software, this video is an accurate description

Holy shit. That made things very clear. Thanks

Great video. Thank you

Thanks to LE for making Telcom more easier to understand.

Thanks for sharing this information....

Nice presentation. Please, explain details about the multiple access.

I am doing my masters in Communication system the concepts here are so insightful

Thank you Bro for very imformative contain..

Thank you for such a great video and your dedicated hard work. God bless you.

Thnk U. I only hear about 2G_Spectrum-'SCAM'

Wonderful explaination

Great work👍

Really helpful! Thanks

🔥🔥🔥 These fires came while listening 🎧....

wow! super easy to understand!

I like the hacker has a mask.😂😂

nice explanation...!!!

Perfect in action of electromagnetic power.

Could’ve used a more tangible scale for the EM spectral picture, in place or in addition to the solely Hz range.... and another scale describing a relative attribute for the wave form at the top woulda been good also.

in the RYB balls falling in cup example, a smaller ball can still fall into a larger cup

Notes 1. The information signal is delivered using EM from cellular data to tower. Every EM waves (analog signal) have it own frequency and amplitude. 2. How the signal reach the accurate receiver? The frequency signal differs for every users. Mobile phone will only accept the signal where the signal assigned to it. Every signal has it own data frequency. 3. Other fq will be rejected by phone filter circuit. 4. Each devices has it unique frequencies. Or frequency ranges. So each device has it own fq range. 5. Antenna are capable to transmit signal into this frequency range or band. 6. Every device filtering circuit also allows a fq band. 7. Udung frequency modulation. High fq express as 1, low frequency express as 0. 8. Signal sent over the fq are protected by every device encryption. Which mean only your device can decrypt it. Hacker can’t access the information. 9. As the world is wide, EM is limited. Assigning a unique frequency range yo each user in the world is impossible. Why fq bad is limited and how to overcome. Notes about EM spectrum. - EM energy increase while wavelength decreases. - in order radio wave to Infrared, uv waves and gamma waves. -higher fq of EM, the worse the penetration capability. - Nntilah sambung

Thank you so much.❤

it's very informative 😮👏🏻

QAM is so familiar to me, I remember that was one of the questions in my telecom exam. But I still don’t understand it...

Woah this is sonuseful and well presented But the ball fountain analogy has a quirk Smol bols get into large holes

Keep going !

1:56, daaaaaamn

Thank you so much @Lesics 💖💖✔

good video!!!

5:11 But is it not a problems that this wave has discontinuities?

Great video

Great video 🙏🙏🙏🙏🙏

1:52 - Good lord! Look at the bazungas on that one.

This is very good

Bagusnya explanation ni 👍🏻

To the point!! ❤️

wow great video

Great , thanks for explaining in very easy , pls come up with more topics

I like you guy you're very clear

nice video!

It's really high tech...😍

Can you do that with antenna? I mean the difference size or length or possible locations up down?

Also Dr. Stone is an amazing manga, must read for tech historians

"your government is able to garner a huge revenue..just by being a regulatory body" Perfect way to end a great video

Transmitted data are mainly encrypted. So, no two users can receive same data. Different users are assigned different frequencies to avoid interference.

thanx for video ^^

Dope. Now, how does my dishwasher work?

Hello, what increases or decreases the transmission power? Voltage or amperage?

Thanks but that didn't really give a complete break down

So my phone is able to send a signal to a tower miles away? Never realized it’s that powerful or at least doesn’t require much energy. Maybe I was looking at this wrong the whole time.
