Thanks bro you also did a great job
The best my mentor in LoRAWAN thanks Dr.Johan Stocking, and another mentor, Thomas Telkamp
One of the best presentations I have seen in a long time. Johan explained it systematically.
Insanely well explained. Thank you so much ❤❤❤❤❤
Thanks a lot for providing conceptual and compact lecture.
Thanks so much for the excellent introduction!
Great presentation, as the tile says: Everything you need to know about LoRaWAN in 60 minutes... Saves my time, thank you !
Phenomenal presentation! Very clear and concise. Thank you!
This is a beautiful video that is absolutely necessary for growing this technology. I just discovered LoRaWAN but it really fits my use case and I am excited to dive deeper into this technology!
very thoroughly and comprehensive!
Great talk, thanks so much!
Awesome, loved this !
Great presentation, making the complex simple.
Excellent talk, thanks!
Awesome learnings thanks Johan.
Really amazing video. Thanks for sharing
Thank you for very good information, highly recommended
Very informative. Thank you!
great and complete presentation...
thanks so much!
Great Material ! 👍
One of the most important tacke aways of the session:
"Make sure that your solution can still work even if you loose maybe 10% of the msgs"... "Allow some redundancy".
Very important to keep this in mind !!!
How do you measure that 10% loss? And how do you calculate scaling up the number of devices?tks
Hi @@youngkevinsmith .
Not sure if the question was for me 😜 In any case I will answer.
How do you measure that 10% loss?
I imagine it's purely based on practical data, which is very simple to do. Imagine a device should be sending a msg each 5mins. So, after 500mins (5minsx100) you should have 100msgs, then it's easy to see what is lost.
And how do you calculate scaling up the number of devices? I think the number of devices has very very little or even nothing to do with the number of msgs lost. Why do you think that? Greetings from Belgium.
@@omarcruz6326 tks for your reply. I guess I am trying get to workout the 2 out of 100 messages that are lost. How do you work out why and how they were lost?
And at the same time this 2 in a 100 lost messages could increase as you add more end devices. Which again I am trying to understand the why and how. And what the limits, number of devices for example, are of the system?
Hi @@youngkevinsmith .
"How do you work out why and how they were lost?"
That's a good question. Yes, I do see some msgs getting lost sometimes, not very often but it does happen once in a while, reason why I consider important the fact of putting things in place to make sure that all works fine even if some msgs are lost. For these few msgs did I finally find the exact reason? Nope. What did I do? Well, I implemented a bit of redundancy to be on the safe side, like sending a periodic msg each X mins. If one msg is lost, it's not a big deal. That solution was good enough for my case :)
@@omarcruz6326 the system I am working on needs 99.99% or 100% reliability of messages on the downlink in a 10 min window and retries are allowed to help get it to 99.99%. Challenging!
Hi, Thanks for the excellent presentation. Wondering if it is possible to share the presentation material ?
Fascinating! Great presentation. I'm from a Wi-Fi background and have had no exposure to LoRaWAN, but I'm going to get some gear and try this out for myself. Thanks for sharing this information.
Glad it was helpful!
Same here, I‘m also a Wi-Fi guy starting to study LoRa. This video is perfect, so much detailed knowledge in only one hour. Good explanation and very helpful pictures and tables.
Now we need somewhat translating ali to Helium Neta app!!!
great application for cold chain
Any news on 1.1.1?
This would so benefit from a table fo contents...
I added an index...
Thank you for the presentation. I'm new to the subject, so please pardon me. I'm looking at the "Math model" graphic. Shouldn't the path loss curvature be reverse to that shown if the signal spreading is a inverse square of the distance? Maybe I don't understand logarithmic dbm scales well enough.

Thanx for the presentation )) One question, what happens if the node emission does fail? Is there a repeat algorithm in one of the upper layers? So, is the transmission acknowledged to be 100% safely sent to the Gateway?
Explained at 49:00... thank you! :)
Great job Mr Johan. Just one thing, the unit of free space path loss should be dB instead of dBm, I assume this is a system which scales down the power transmitted rather than causing a specific power loss (like mW)?
Also in 19:30 formula I guess you forgot the free space path loss?

What is the packet size for lorawan with an 8byte payload?
Hi, I would like to know which Network Server - Open Source to deploy on my own servers do you recommend?
Thank you for your suggestion.

At around, 20:13 you say there is Antenna Loss on the Rx side. I suspect you meant to say Antenna Gain. Your graph there shows gain as well.
Around 36:10, the CIA triangle, the A is traditionally Availability, not Authenticity
@@bryanward8646 , yep, You are right, I also noticed that.
What was meant was Rx connector loss instead of Rx antenna loss.
Atv49mins how do you measure tye packet loss in general or at the gateway

Where is this recorded? Or is it a green screen?
Other than mining helium HNT how else can I help the network grow? That will increase my mining growth but also help LoRawan
At 20mins path loss model
Hello, can anyone here guide me about how can i use the LoRaSIM simulator and using it to simulate a LoRa Network, nodes, gateways and Network servers. Also, the use of the adaptive data rate on the LoRaSIM.
Hi! This is a great question for www.thethingsnetwork.org/forum
As usual theese radio transmission regulatory limitations introduced by law are something nobody is checking, real limitation is only power and that is being used with "squerq" modulation that is particularily advanced one - supposed to be efficient...
