    Well never heard of underground cables before

  3. Manjunath B on October 10, 2021 at 7:01 am

    Then where is the involvement of communication satellites ? Not at all ?

  4. Samuel Aditya on October 10, 2021 at 7:03 am

    How do phone have enough power to transmit data to tower?

  5. Kenny Crage on October 10, 2021 at 7:06 am

    Your phone uses microwaves instead of radio at least I thought

  6. goutham Ganesh on October 10, 2021 at 7:08 am

    Great video for someone in Wireless Domain..

  7. S P E C T R A on October 10, 2021 at 7:09 am

    Can you do a video on how Cellular data signal wave works? Eg: the signal distance a tower can cover and will someone get signal if you get closer to the tower?

  8. Oussama Sghaier on October 10, 2021 at 7:10 am

    Nice Video

  9. Kovvuri Shaheena on October 10, 2021 at 7:12 am

    It’s damn awesome…. Very satisfied

  10. Hs slay on October 10, 2021 at 7:14 am

    Elon musk definitely watched your video before launching starlink

  11. Big Thief Sweaty on October 10, 2021 at 7:14 am

    so… you mean to tell me we have these cables running along underground across entire oceans? And we’ve only recently discovered this technology (or so we say). It doesn’t add up. I think society is strictly set up and people have been running things longer than we think; brainwashing the entire population by implementing information on how society was formed at a young age creating their schema – which they can’t prove wrong or see any other way because it was built into their brains at birth. It’s run like this… simply because of the ego and selfishness. There’s no need for a social structure like capitalism or communism; if everyone simply worked for each other, out of love, the amount of things humanity could get done would be unfathomable; but as of right now, we are constrained. Wake up y’all. It’s set up… society I mean. Don’t let it control your life. Create and experience it to the fullest!

    Amazing, thanks!!

  13. Kenneth Koh Juin Long on October 10, 2021 at 7:18 am

    And today starlink happened and wireless all the way around the globe is soon possible

  14. Hrithik Sonu on October 10, 2021 at 7:19 am

    That is what Elon musk is building StarLink to get the data go wireless

  15. ᴡᴀʀᴘʀᴏᴍᴏ / E D I T S on October 10, 2021 at 7:20 am

    you probably searched this up
    if you keep being curious, you will become a smart person.

  16. SHRIRAJ SHEEJA RAMESH on October 10, 2021 at 7:20 am

    Cant thank you enough sir…
    I needed this information for my project!!

  17. xSWAGCATx on October 10, 2021 at 7:20 am

    Who else thought that when you pressed send it went to the cell tower and just jumped from cell tower to cell tower until it reached its destination?

  18. nico Blay on October 10, 2021 at 7:23 am

    This is information every second grader should start learning to understand how to expand their knowledge. Beyond what they see and. Let them know seeing is believing, but doesn’t mean correct always.

    This video is just brilliant! Well done!

  21. lapistea on October 10, 2021 at 7:26 am

    this may sound extremely stupid, but i can’t wrap my head around programming. like how did it appear and how is it… like HUH?

  22. Lisa Swartz on October 10, 2021 at 7:26 am

    This is awesome!

    Have you had symptoms such as fatigue, headaches, poor memory, difficulty sleeping, and lack of clarity in your thoughts? It may seem like these could be the results of daily stress and frenzy, but there could be another culprit. All of these are symptoms of electro-sensitivity, which is something that more and more people find themselves affected by. Studies conducted in 1997 found "less than a few cases (of electro-sensitivity) per million", however now as much as 2.5% of the population is affected by electro-sensitivity. Even with the most moderate calculations, electrosensitivity is 10,000 times more common today than it was 20 years ago. Why could this be?

    Electro-sensitivity and its symptoms appear to be triggered by certain microwave frequencies of electromagnetic radiation. Due to their high frequency, microwaves allow for higher transmission rates and smaller antenna sizes, which is perfect for high-tech devices that are constantly getting smaller and faster. These are devices such as cell phones, tablets, laptops, and any device that can connect to Wi-Fi, which can now include TVs and refrigerators

    Woow ! Thanks for this ! Science, Technology and Invention should have been my path starting at age 11, well now many many many years later and after path has diverged , WILL have to LEARN at the SPEED of LIGHT and CONDENSE ALL THOSE YEARS in 11 Days…In a Parallel Way by MAGIK ;0)….

  28. Indigo on October 10, 2021 at 7:32 am

    So the radiation coming from my phone is powerful enough to travel miles, able to withstand all changes resulting in perfect exchange.

  29. goldibollocks on October 10, 2021 at 7:33 am

    Hold on… I don’t fully get the teacher analogy. When students raise their hands, the teacher will see them do that and the student doesn’t have to speak for the teacher to notice him. But when a cell phone wants to send something, it will have to use waves, too, right? So it basically has to speak to the tower to tell it, that it wants to speak. How does the tower differentiate between 1000s of cell phones sending waves to ‘raise their hand’ at the same time? In the classroom example that would translate into all students not raising their hands but saying ‘pick me, pick me!’ all at the same time? How does the cell tower manage that? It can’t be the one that ‘starts the conversation’ because it can’t know at which moment each connected cell phone will want to send something, right? The conversation will have to be initiated by the cell phone… using waves?

    With the launch of 5G networks around the world, this year, we are seeing an increase of news,
    reports and leading health organizations discussing the potential harm of EMR and the importance of identifying solutions to reduce these harmful rays
    For those who claim that the electromagnetic waves we are surrounded by and bombarded with every day are harmless they must reflect!
    They said the same about ethernit they put on the roofs of every house because it was considered safe for man!
    Only after years when the truth could no longer be kept hidden have they classified ethernit as carcinogenic to humans, as it is responsible for the death of thousands of people. So they ordered its disposal declaring it highly harmful. Same for asbestos.
    Even for tobacco they took years before stating that it can cause lung cancer, acute bronchitis, pulmonary emphysema etc, meanwhile the multinationals have profited for years against unsuspecting people.
    And so for many other cases, different from each other, and it is the same for electromagnetic waves, radio waves etc .. there are already studies that prove that they are responsible for some types of brain tumor, such as Glioma, but most some people still don’t believe it.
    Why wait to get sick when you can protect yourself in time and inhibit the harmful effects of radio and electromagnetic waves thanks to tested, safe and functioning devices?
    AiresTech products are the solution in my opinion
    for those wishing to learn more click on the link:

    This is just my opinion which I hope will be positively received, shared and circulated in a constructive and instructive way
    A greeting!

    not enough fact. please explain in detail rather than using metaphors so you can skip the research

  34. Diploma Tutorial on October 10, 2021 at 7:36 am

    Thank you. I got the answers to all of my questions in a single video.

  35. Ferocentaur on October 10, 2021 at 7:38 am

    "You’ll need a lot of satellites to cater to BILLIONS of users and their data needs…." There are no [3,000 active] satellites launched into low orbit. That’s just a ridiculous conspiracy theory, So I know this is serving up a fabricated crock of cooked up bullshit there. And the hypothetical gravitational wave is based on a prediction by relativity theory…..which is just a theory passed off as fact. The term "Gravity" from Latin’s "gravitas" meaning "HEAVYness".

  36. 2aizen on October 10, 2021 at 7:39 am

    hi, 2021 starlink is a growing thing.

    Here we are

  47. Lyrics Universe on October 10, 2021 at 7:57 am

    Excellent explanation. You explained every single point. Thanks.

  48. Stanisław Nowak on October 10, 2021 at 7:58 am

    I am one ot the guys who thought that all comunications is do by electromagnetics waves, but it is not so I am really suprised.
