I cannot actually upvote this video enough, so much easy to understand Information, starting from 0 and quickly getting to the point in such a short time! You are a hero of the Internet, dear Sir!
wow.... Richard... your instruction is exemplary. you've taken very complex subject matter and made it attainable to anyone! As a teacher of RF, I appreciate you sincerely!
Thank you. I only wish that I'd kept the complete video that this was part of. Have you played with 'Meshtastic'? It's a great tool for teaching practical, low cost. IoT based RF, I'd have thought.
Much respect for the clean explanations, i ve spent many time on courses (hours and days) and i didnt feel the same about this 3 minutes, just clear & easy to understand ^^
This is the analysis I was looking for! Many of them on YT are misleading about the idea of this modulation and do not explain it as clearly as you using slowed down waterfall visualisation. Thank you!
Thank you for the good explaination. Helped me alot with working on LoRa technology. Audio visuals are sounding like alien noises. Keep up the good content Richard Wenner!
Thank you. Good luck with LoRa - Have you seen this? www.move-x.it/cicerone-board/ The Neo 10 is brilliant and the processor has a radio included WITH a LoRaWAN Stack (I've made a video - yet to be published)
Fantastic visualization, I've recommended all my students watch this to help make sense of the nonsense that I have said trying to communicate these ideas!
Thanks i was interested in this chirping method, wasnt looking for it but yt suggested this vid on a second page. I wonder what's the information density with lora in a heavily populated spaces
As a spread spectrum technology it is perfect for layering/sharing RF signals across a wide frequency band (like WiFi). Remember the LoRa packets are very, very short and there are additional provisions within the LoRAWAN stack to increase the resilience of the system as a whole. Obviously performance is better in rural/quiet areas but again in built up areas (radio noisy & relatively hostile) the use of more concentrated nodes (like mobile phones) can also be used but I've no information about any areas where saturation has occurred.
@@edinfific2576 I failed to find a frequency response curve for a mobile phone - it would certainly peak around those frequencies. I probably don't consider viewers on mobile enough. I find the screen to small to read but thanks for the feedback. We have run some of these in a full-sized cinema (our 1000 student screening) where the bass response is terrific! :)
May I ask how LoRa achieves while SNR is minus value ? How is that theoritally and practically achieveable while signal power is worse than the noise ?
In conventional terms the signal will appear to be embedded in the noise - in analog terms. Noise is random. The digital codes that spread the RF power across the frequency band are 'pseudo-random' but repetitive. If you know the details about the nature of these codes and can synchronise them in your receiver - reverse the spreading process - then the signal recovered signal just pops up. Is this of help?

Thank you. It's appreciate and makes the work worthwhile.
Excellent explanations and visualization. Much thanks for your time and enormous effort.
Thanks - it took over a day to make such a short item - so your feedback is appreciated.
What a professional voice actor ❤
Thank you.

This was one of the most concise informational videos I've seen in a long while. Thank you for making this!
Deep down really shallow? Thank you.
By far the best explanation for LoRa ever made.
Thank you.

Most satisfying when the penny drops. I hope your feeling was good.
it's incredible how simple you've made this seem! thanks a ton!
Thank you

Glad it was helpful! Thank you
Woah!! This video is absolute gold! Thanks for explaining modulations first and then css!
Glad to make you happy :)
Wow. Easily the best explanation and visualisation on the topic. A big thank you! :3
Well - thank you! Merry Christmas.
Congratulations for your astonishing work in making something as complex as this much simpler to understand. Thank you
Thank you.
Richard - what an excellent video - simplicity, clarity and engaging - thank you.
Thank you. I only wish I could find my full version of this video that this comes from. :(
Fantastic video, thanks for putting it out there.
My pleasure thanks for your reply.
Very nice video. Keep up the good work!
Very good. Thank you Richard.
Cheer Jakub.

This was a marvelous explanation. Thanks so much for making it.
Thank you.
This is great - much appreciated.
Glad to be of help - thank you.
Super description and perfect narration.
Wow - what an easy to understand explanation to a rather complex topic! Thanks!
Thanks.
Fantastic tutorial, lots of reading and this has consolidated it all, and so professionally presented. thank you.
Thank you.
good explanation and visualization. Thanks for your effort.
Thank you for the feedback. I hope that this is useful for you.
Fantastic visualization, I've recommended all my students watch this to help make sense of the nonsense that I have said trying to communicate these ideas!
Deep down it is all terribly shallow :) Thanks and best wishes.
@@richard_wenner I have tried to describe OFDM as chords using a toy piano, I think that the sound metaphor is really a good one! Happy Holidays!
This is such a great explanation! Thank you!
Thank you Antonio - Anthony is my middle name :)
Very nice, thanks a lot!
Jesus Christ! What an excellent explanation!!!! After finding this I feel today is my lucky day.... :)
Well was it?
Really expressive !! Clear to understand , thanks to you effort!!!
Thank you - it is a snippet from ruclips.net/video/WizST6gighs/видео.html - if you can stand more? :)
Great stuff. We need more of that.
BEWARE of what you wish for! This is part of an hour long presentation :)
Thank you for sharing this information in an easy to digest way.
My pleasure - thank you for your comment. It makes these things worthwhile.
One of the best information video ever. Thanks a load
Glad it was helpful!
Nice work!
Really great explanation, thank you.
Thank you.
Yeah, what everyone else is saying. Great job - super understandable explanation and visualization. Commenting to feed the algorithm.
That algorithm is veracious but also lovely, clever and inciteful. Really knows how to sift the wheat from the chaff. :) Cheer
Excellent. Thanks!
So clear and awesome explanation 👏
Thank you. Smug mode ON! :)
Wonderful! Thank you :)
Thank you!
Wow wow and wow, it is the best video. Please make more.
Thank you. I will when I have the time.

perfect! even I understand now!
Wish i could hit the thumbs up button twice.
Works for 3 times but not 4 times for some reason.
thanks thanks thanks
I wasn't aware that there is some acronym behind birdy chirping chirp, high intensity radar pulse, sonar pulse has similar sound
I don't think I was
Amazing video! Hugs from Brazil
Thank you! 😃 I'll collect the hugs next time I'm in the area.
Very interesting tittle , thank you for your excellent work!!
👍👍
Thank you.
Excellent work :-)
Excellent explanation of Meshtastic
Thank you.
Great video, thanks!
Great explanation. Thank you !
Cheers
Is there a part 2? it seems to end just when it is getting the most interesting and informative about how LoRa works.
This is a short part of ruclips.net/video/WizST6gighs/видео.html I think - nag me if it isn't.
Hi Dave, I think this is part of ruclips.net/video/WizST6gighs/видео.html otherwise try this:- ruclips.net/video/NoquBA7IMNc/видео.html
1:04 TV terrifies cat. Lol
1:37 Cat left room in disgust....
Great intro, made easy by a maestro 👍 thanks 🙏
Watch it - I could do more! :)
Heck - I have! ruclips.net/video/WizST6gighs/видео.html
DAMN! That FSK siren-like example could have been toned down at least 2-3 times! Your voice was drowning in it.
Were you listening on headphones?
@@richard_wenner No, it was over the phone speaker.

that was fantastic. Any more videos coming on the topic?
I've done a few - thanks Osama. (have you decoded the morse?)
Richard Wenner will dig into them over the weekend 😋😋😋. Planning on decoding the morse as well. Thx again for the fantastic content.
Hey, you are back! How wondfull!
Excellent explanation
Thank you.
Is any (video) tutorial exists on using cheap 820T2 china SDR to grab raw packets and decode it in software under Linux?
Thanks
Thank you - makes it worthwhile.
neat video, Rich.
Cheers Nept! :)
Whats a pace? when you dont have time to vote a peace example
eh?
Awesome! Thanks for the great video and explanation! Very useful! :)

@@richard_wenner really not I think. Let me go further, I will reach you if need again. Thanks.
Richard you can use MATLAB codes from my blog to create more graphs and make many more animations.
Thank you and thank you for your excellent content.
Super explanation
Thank you.
Is there any way to hear just the audio of the chirp?
Well it would be like listening to bats - you would have to down shift the signal significantly to hear it.
all that in a 4 min video, hahaha
Not like the other click bai on RUclips?
I was just getting into that before the abrupt finish
