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 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 !!

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

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!

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

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

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

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!

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

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

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

This topic is great for me . Thank the creator !

Very informative Video. Thanks a lot !!

This is great😀! Thanks for the video

Explain in such a lucid manner!

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

What a channel. 100/100 loved it

"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

Perfect illustration.

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

Such an informative video! Thank you!

so nicely and precisely explained. thank u for the stuff

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

Wow glad I discovered this channel very informative thanks

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

Excelent video! Thank you!

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

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

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

Best example given it really helps a lot

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

Really awesome! I highly appreciate Learn Engineering.

Thanks to LE for making Telcom more easier to understand.

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

Awesome wealth of Knowledge!

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

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

Excellent Demostration !!

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

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.

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

Thanks for sharing this information....

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

Wonderful explaination

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

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

Very very nice explaination.Thank you sir

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

Thanks a lot guy This is Great information for me

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

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

Great video. Thank you

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

Perfect in action of electromagnetic power.

Great work👍

Keep going !

I like the hacker has a mask.😂😂

Thank you Bro for very imformative contain..

Bagusnya explanation ni 👍🏻

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

This is like some esoteric magic

Imagine you are talking to someone and you hear several voice 😂😂

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

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

Thank you so much @Lesics 💖💖✔

Thank you so much.❤

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

nice explanation...!!!

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

Really helpful! Thanks

Holy shit. That made things very clear. Thanks

it's very informative 😮👏🏻

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

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.

Great video

Great video 🙏🙏🙏🙏🙏

wow! super easy to understand!

wow great video

1:56, daaaaaamn

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

To the point!! ❤️

OFDM was the saviour for intersignal interferrence and multipath rayleigh profile delay spread, a truly remarkable technique to modulate signals,

You are great

good video!!!

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

1:53 Keep up the good work

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

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

Good video

It's really high tech...😍

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

nice video!

7:32 welcome ☺️❤️

Very good and informative vodeo. Thankx savin bro.👍☺☺
