@@rji5377 thanks to fibre optic cables laid underground and under sea/ocean which literally use light to transmit data. Without fibre optic technology, data transmission of any kind wouldnt be this seamless and quick.

Never to late to learn something new :-)

I know I'm three years late on this but maybe your background can help (I assume the 2,900 comments will prevent this from being seen by the poster). The initial journey starts with the caller talking, and explains the path that the sound travels. Later in the video though, once this signal hits the home MSC, it seems like the phone call wasn't yet made and the MSC is first trying to find out details about the person being called. I'm assuming that the sound generally follows the same path as the dial, but I'm still curious if things are a bit more streamlined once the connection is established, or if the sounds still need to go through all the same hoops that the dial goes through.

In school it's not about learning, it's about complexing simple things and act like this is a hard topic. For example we try to learn a 3 axis geometry shape on a 2 axis notebook.

👍

You just weren’t ready to learn it at that time

@@jessieleigh89 yep I feel the same way

You said it!

Humans have to evolve for such reasons ❤

Your video's are also knowledgable

It's still stupid. In my free time, I've drawn dozens of models of how phones communicate. This is nowhere near what I expected. After all of this research in technology, this is what they come up with? I hope that one day I would make this better...

Very interesting video tho kinda basic as a few parts of the system are missing With regards to the MSC they are becoming outdated now thanks to fiber being rolled out pretty much everywhere But let's say within the 3G days and let's just stick to one network only for now the system consists of tower MSC a sub system and central system The sub system is generally what does most of the work and it's where multiple MSCs are linked and generally where customers who are logged onto the network is stored The MSC controls the BTS towers several of them in a given area and the MSC is responsible for dealing with the handover between towers within its area of responsibility and the MSC updates a database at the Sub system so the system knows where your phone is at all times The sub system as mentioned is where all MSCs link to usually a sub system is within a large city somewhere and usually within a network there is multiple subsystems that are linked before they are linked to a central system usually the networks head office in most cases sub systems double up as data centers as well But the sub system is responsible for handing over calls to another MSC within the sub systems area of responsibility or route it to another sub system As for data as mentioned in the video sensitive data such as customer name address and subscription are NOT stored at MSC or Sub system it's only stored on Central Only data that is stored is usually on sub system and MSC some networks can even store it at the tower but the main database is at sun system and this data consists of mobile number and the SIM cards for example sake serial number and also it notes the phones IMEI these details are held so the system knows where each phone is logged on to the network so it knows where to send texts and calls or if you are a criminal police can find you hehe and it record's IMEI mostly for blocking it from the network should your phone gets stolen To make a call to another mobile network or landline then the sub system will route the call to that network and make connections if international calling it is usually routed to central before pipping out to whatever line required But that's olden days tech with Fiber it's cheaper and faster to cut out the MSC networks started to link the towers directly to the Sub system and sub system usually becomes a data center also again to save running costs My mobile network I know where their sub system is where all the MSCs are linked I got a tour of the place bloody huge building one corner of the building outside has a huge tower with all the microwave transceivers that linked all the MSCs now obsolete

Well they do have the benefit of scale. Basically everyone has a phone and in the US there are only like 4 major providers. They have a ton of money to spend on infrastructure and a very secure and stable revenue stream

Hahhahaha

Right?! How did they even conceive this idea.

@@seang81 This explains why this technology is making people stupid and lazy!

Because electromagnetic waves speed in air is approximately 0.3 million kilometers per second

not in a seconds, microseconds

Not in seconds ...... Within nano seconds

@@poojabonda7593 not in nano seconds..... in Picoseconds

Yeah cuz electromagnetic waves matter..

Brother these were also taken from books or any researches you should say the ass schools and colleges 🤘🤘

This is just basics, there is a lot of theory behind signals, you can't pass any exams with the vedeo. It's a great vedeo though.

Not an engineering exam. U can still get the books for free tho so ur point still stands. The only thing i can ssy schools sre good for is recommending which books to read out of the millions that are available

@@sthandiwe7825 True ... but university prescribed textbooks are still one of the worst ways to learn a concept

Kinda like thinking a thought. It takes a few microseconds to process a thought, but a good amount of time to justify it and explain the reasoning behind it (like for example solving a physics problem).

@@VivekYadav-ds8oz For me Solving a Physics problem will take an hour or so...😂😂😂😂

@@SOFTWAREMASTER Depends on what kinda problem you're solving.. I'd easily eat up whole day on a single problem for some problems and brush some off as too "low-class" (or repetitive) for me to even consider solving. So yeah it depends :)

FDMA Or TDMA is very important

Well this technology took 50-100 years to perfect it so...

What about those who invented zero

@@abhijitmoholakar8217they are amazing and funny.

Freddie Capillan i too find technology like the internet amazing, a web of cables that transfers shitloads of data constantlu around the world.

amzing and funny it’s nothing to do with zero, the binary concept is about on/off state and the combinations of those states which carry the information. We just found the way to code and de-code the information that way. There is nothing to do with actual numbers

The same conversion of 1 and 0 to analogue and back is also how CDs DVDs and ipods work. It is indeed incredible and is a whole subject in itself.

They used to tell us it was satellites out in space? When there is no such thing it's all lies.

Yes.Its true ❤

Emma thick

I’m too high for this!

🤣🤣🤣🤣 you made me laugh

😂😂😂😂

What are you doing these days

I don't think it's too complex. But I still have no clue how EM waves behave, if they're at all different from light/radiation, or how they're magically manipulated to have certain frequencies or amplitudes. But past that, it seems all that's left is optimization.

😂

there is no satellite lol

Satellites were missed out for clarity. They are only involved for long distances, around the world, or across a continent.
