I've done communication engineering courses, the amount of background requireded to understand how this stuff works is crazy. The fact that you managed to provide a Layman's explanation for such an advanced topic is very impressive. No Fourier transforms or complicated math, well done.

I work on cell towers, just like the guys you see in this video. We don't need to know all this stuff for the job , but it's good to know. It's too bad that there isn't footage of the small buildings (shelters) that accompany cell towers. They are quite complex with all the wires and hardware inside, along with the great deal of cabling that each cell tower has.
This is one of the greatly underappreciated jobs in our modern society. The guys don't get paid enough for the benefit that each user receives every day. Imagine the coldest and hottest days of the year for you and spending 6+ hours a day outside doing physical work. The wind speed multiplies with every small increase in elevation as well.

As an electrical engineer, I remember learning all of this in my Communications class, but it literally all flew over my head. But Sam was able to get it understandable in less than 15 mins is astounding

You packaged a hugely complex object into an understandable format without using formulas. That's very impressive.

my dad told me that when he dropped out of school in the 70s, his dad asked him what he wanted to do with his life-- and he told him "i wanna know how they take a signal out of the sky and turn it into something you can see or hear" .. he ended up becoming a tech that specialized in repairing antique radios and he was heavily into tinkering with new electronics as they came out, his room was covered in antennas and oscilloscopes, and he was always very excited to share any stories he had about broadcasting and loved finding out stuff like this
he passed about a year ago but i'm very sure he would have loved this video, great stuff

I watched several sections of this video repeatedly so I could understand what was being explained. It was like attending a Telecommunications Engineering Lecture but with a super interesting professor who had amazing visual aids to explain concepts and and you could ask him to repeat what he said multiple times until you got it. This is the way learning should be. I knew parts of this earlier but never has anyone explained so clearly everything starting from scratch. Thank you so much. More people need to watch this.

Reminded me of a lot of statistics we had to do in school around the topic⌠Some of the topics he discussed in case youâre interested:
AM - Amplitude Modulation
FM - Frequency Modulation
Symbols
PSK - Phase Shift Keying
BPSK - Binary Phase Shift Keying
QPSK - Quadrature Phase Shift Keying
QAM - Quadratic Amplitude Modulation
8PSK, 16PSK, constellation diagram
TDD - Time domain duplex
OFDM - orthogonal frequency division multiplexing
CDMA - Code Division Multiple Access
SNR - Signal Noise Ratio
BER - Bit error rate

I keep expecting the Half As Interesting guy to make a terrible joke but he's actually just really helpful over here

This is one of those videoâs where the transition between âduh, this is basic stuffâ and âwow this stuffâs incredibleâ happens without me noticing. Keep up the great work!

I have been in the wireless communication field for over 20 years. I have seen the growth and change. Brought many memories when i started working on analog networks, IS-136, GSM, CDMA. Very well done!! You managed to explain very complex processes in a manner an average person can understand. Mobility, how the phone switches from one cell to the other, is the next hurdle. But overall great video. Congratulations.

I just bought CuriosityStream specifically to watch your "The Colorado Problem". As someone who has lived in Colorado for the last 3 years, I had no idea how interesting the task of "getting everyone water" in the state (and southwestern part of the country) could be. Happy to support you and the others that spend their time educating us. Thank you!

This video just blew me away. To break down such a complicated technological subject, starting with the nature of light itself, to transmitting thousands of messages simultaneously, step by step, so that each step builds on the other, is a very rare talent. I have a new respect for our telecommunications system and the people who make it work.

Yeah. This is a masterpiece. Iâve been designing cell networks since 1997, so this is second nature to me, but Iâve never seen such an non-intimidating explanation of things like QAM and CDMA. Like 100% of all books whack you over the head with matrix transformations or polynomials on page 1, and they lose all but the most determined learners right there.

The way the video evolved from the very basics, easing things up until it reached the very complex concept of CMDA is just genius and very engaging! Kudos to the team for a job well done. Probably one of the best explainers I've seen.

You are absolutely an amazing teacher, illustrator, storyteller, and information gatherer.
Thank you person or persons behind Wendover Productions.

As a Telecommunications engineer graduate, I wish I had seen this video a few years ago. Really helpful and well explained information

As someone who works in the telecommunications industry I want to thank you for this video. Making such a complex topic relatively easy to understand. The average consumer gets mad when their data slows down or call gets choppy, but they don't understand that there are quite literally physical limitations to cell service. Now throw in multiple telecommunication competitors all fighting for spectrum and the logistics of providing cell service gets even more complex.

I hate you for being better at explaining these things than every engineering professor I've had, and yet I just have to listen to you for free even if it's mostly just surface level. I love you for all of it, and nebula is super worth it, thanks for your content

Just as cell service tries to cram as much data as possible, you've managed to pack so much genuinely interesting information in this video while still making it understandable to the average person. I've learned so much. Thank you.
