How does your mobile phone work? | ICT #1

very useful

My phone got hacked by SS7 attack how can I fight back? Advise please

Women never call firt to man

Great video Sir 👏

awesome info

The lady at the start looks like Sunny Leone.

What is the difference between a telephone company and a mobile phone operator?

Awesome work. Precise 👍

Narrator: "However, electromagnetic waves are incapable of traveling long distances"...
Starlight that has travelled millions of light-years to hit the night sky: am I a joke to you??

It amazes me that someone woke up and had an idea

You forgot the power of the phone which each the battery in order to run the device.

Dear Sir/madam

I write to inquire if your company can supply Rice / kidney Beans, Sugar to war countries like Congo DRC, we shall make an upfront payment before your supply.


Best Regards

As a first time investor I started trading with Mrs JESSY, with just a thousand bucks my portfolio is worth much more now within just a weeks of trading with her.

As a telecommunications engineer, I have to say that there is so much of inaccurate, incomplete or wrong information about how the mobile communication works in that video that I don't even want to explain them all... You should have studied the topic better and then make the video...

Fibre and not fake satellite

What in case of forest area or ghat sections signal not there, after we will get the signal. I don't believe that what said is fully, it is partly correct. Because in case of oceans travelling from one country to another is long way. Who will put wire connections there. There must be technology used there.

Flat earthers losing their shit over this video

This explains why the audio from these devices is so BAD!

Even when john travels to a foreign MSC, video says the "request" first goes from Emma's home MSC to John's home MSC. Does that mean that the whole call goes through John's home MSC or once its known from the "request" john is in foreign MSC, does the "call signal" just travel from Emma's MSC directly to john's foreign MSC? I am wondering if the "request" communication figures out the right MSCs, then does the "call signal" just travel between those MSCs? Example, Emma and john both have the same home MSC in Atlanta but they have both traveled to foreign MSCs in Los Angeles, does the whole call have to keep traveling cross country to the home MSC or does it just travel between the MSCs in los angeles?

YES VERY GOOD---FROM BANGLADESH ON 20/6/2023

That's a lot of MSC's

I'm looking for more detail such as
- Voice is converted to PCM; what is the sampling rate and how many bits per sample?
- How is the PCM encoded for transmission to the cell tower? Modulated onto an analog signal? How?
- What is the optical coding for fiber transmission between towers? Back to PCM? How multiplexed for carrying many signals?
(I have some background in the old analog FDM over microwave towers but would like at least a broad understanding of how digital long distance works, over land lines and mobile.)

I'm privileged to have visited an MSC and wow its good!

the way the original mobile phone was designed to work in 1979 Chicago the aristocrat would talk on this phone then the Harley or magic shop on his scanner would indulge and blackmail....... they would get broken children for 40 years..... then try and hand off the spud onto a t-clubber or hooten holy........ they always thought there was going to be a morel orel in this story.... these autism's are in the legal system now....I'm not griping though amps magic built the computer industry when they demanded personal printers and computers to transcribe blackmail dirt from vhs and betamaxes. that could receive the calls.

alice and bob have sadly perished 😢

Like Bangla language

Funny fact: I see that everything after 4th generation begins to deccay and instead of helping is actually controlling us...here in Europe is similar în auto industry with so called emission Standards like euro 4-5 and now 6 that made cars less reliable than the previous generations!!!! În my country we have a good and more and more apliable nowadays saying and kinda sounds like this: 'The worse enemy of good is better' 😐

I'm watching this on 4th June 2023 in 4G phone.

and remember folks, when you intend to commit a terrible crime, leave you cell phone at home, the police can use your cell phone to track your every move by cell tower handshakes......

Wish we learned this at school

The Family and Job .

Many questions :

1. How digital signal (0 1) can carry the voice ? I mean it may somehow carry the content of the voice, but not the characteristics of the voice. Example: your friend hear exactly your voice sound, and recognize its your voice but not someone else. How digital signal can carry all those things ?
2. So the same question of 1 for the electromagnetic wave.
3. What is electromagnetic wave ? How does it work ? How to create a wave and transmit ? How to catch a wave moving in the environment ?

Who the hell invented those things? Genius.

I'm still waiting for that 5g signal my carrier promised.

But it works so fast I mean the person on the other end of the call hears our voice in Real time wherever in the world he maybe, this is just mind blowing 🤯

But anyhow the smartphone handset having the operating system android or IOS for IPHONE and with its motherboard and hardware are apart from tower technology which do enormous jobs for us

When the antenna transmits the electromagnetic waves of someone's call, all phones in the area receive those waves. How does my phone know that it has to ring now, and why can't other phones intercept our call (is it encrypted?)

So Grateful for this amazing video. 💙💙💙

next thing i will search for is online game latencies insane how fast game reacts to movement xD xD in competitive games

Where are the flat earthers now? 😅

5gtower turn into a 🧟

This video was very informative and well-presented. The narrator did a great job of explaining the complex technology behind mobile phones in a way that was easy to understand. I learned a lot about how my phone works, and I now have a much better appreciation for the engineering that goes into these devices.

I also appreciated the way the video was visually appealing. The animations were clear and easy to follow, and the use of real-life examples helped to bring the concepts to life.

Overall, I thought this was a great video. It was informative, engaging, and visually appealing. I would definitely recommend it to anyone who is interested in learning more about how mobile phones work.

Thank you for this very useful video

Alguien de Inacap que haga un resumen

Great original information,🌹♥️💙💚❤️💜💛🖋️💯💞I like great job

It seems quite sad actually - as humans, we managed to trap ourselves in technologies that will "enslave" us forever...very sad....

Take a shot everytime he says MSC lol

U hv thought us which v nvr knew....million thanks 😊

Amazing explication

Thank you so much for this! This video explained this way better than my professor!

Just wow !!
