        Stop 5G kill towers!!! Its weaponized population control sold through hyper materialistic ignorance. If we dont stop it soon, all life on this planet will cease to exist. Do not buy a new phone and do not upgrade to 5g. Everything your told by the authorities IS A LIE!

                                      In actual matter of fact, its 10,000 times more complex as your voice signals have to go through a millions of transistors to prepare it into something more intelligible signal for computers than what is coming out of your mouth!

                                        the human 3D models are really creepy looking. consider using a 2D image put into the 3d scene or something, its way more 'human'.

                                            KLAMETE, zadávate len techologiu a jej špecifiká. O vplyve na zdravie človeka všetko tajíte; všetky hovory možete sledovař, viete kolko penazí má každý človek na účte, získate o každom z NAS všetky súkromné informácie. Nebudete moct nikam újst pred dosahom na zdravie človeka zhubný vplyv....to je to najhoršie. Vy chcete vediet naše myšlienky pocity. Nevhodných odstránite. Každých 10 metrov bude postavená anténa. KTO nás chce ovládat; nemá dobré úmysly. Chrán nas Pán.

                                                    Mobil phone works like touching the pond with your finger each time you touch the pond information waves 🌊 signals are stronger than last time that get transmitted pulses to your to your receiver in your ear 👂.

                                                    Within 300,000 kilometer circular cube will be received instantly.
                                                    Within 600,000 kilometers will take one second. Within 900,000 kilometers will take two seconds and so on.


                                                    So for example from Australia to USA is 25,000 kilometers so that will take 25,000 / 300,000 = 0.083 of a second. That is like the 83,000 part of a second information pulse would be from Australia 🇦🇺 to USA 🇺🇸 into your ear 👂 thru your receiver.


                                                    That is what you call speed of pockets of energy.

                                                                                        This is way too high level compared to most of your content. I was hoping for a bit more detail, for example on how your phone establishes communication with the relay tower in the first place and how the process works for switching from one tower to another when the phone moves location.


                                                                                        There's way too many gaps in the explanation for this to be meaningful in any way. I'm surprised by all the people saying, "wow, you've explained so much". Seriously? All we've established is that phones convert analog signals to digital, and communicate over long distances using cell towers and fibre optic cables. Does anybody born in the last 80 years not already know this?


                                                                                        Also why bother mentioning concepts if you offer absolutely no explanation to what they are (in the section on the different generations of mobile communications)?



                                                                                        I know this is YouTube, but it's supposed to be an *engineering* channel. Do you need to dumb things down that much?

It tells you right inside your phone not to do that because long term exposure to the radiation causes cancer, brain tumors and depletes the blood brain barrier.
                                                                                            Hollywood does the same damn thing. It’s a subliminal message designed directly to dupe you.
