- In this video, I show you the basic principles of LoRa and LoRaWAN, its plusses and minuses, and also show you my own LoRa gateway and a LoRa client, and send the first message to the things network.
Link budget and bandwidth are introduced.
This technology can be used for Arduino and other microcontrollers like the ESP8266 or the ESP32. It is LPWAN technology.
You find many more videos on how to build gateways and nodes: • LoRa, LoraWAN, Sigfox

...when your device says "Hi" instead of "hello world" because you don't want to use too much bandwidth. :)
Yes. LoRa devices are very slow and do only have a very limited number of bytes to transfer.
Best comment!
73!
Great video. No unnecessary talking face, but only relevant illustrations and clear explanations.
This is how every single TH-cam video should be and not only 0,0001%.
Thank you for your kind words!
Thank you, Andreas, you've compressed what is 3 hours of lecture, that I didn't understand into 20 minutes of knowledge transfer. Keep doing these videos you are an inspiration
Thanks for your nice words!
Can we broadcast message from one lora node to all other lora nodes without gateway?
@@MrNams It depends on the software you run. The easy way is to use LoRaWAN, but that is a specification that works in a star topology. People often use MQTT with it and that works like a post office. The device sends the data to the post office and then all subscribers to that message get it. If you do not want to use that system then you will have to write your own. You could use a mesh routing system but beware it is a big job to code it. A mesh can have identical devices where you can send a message from any device to any other, but one normally uses wifi because it has a higher data rate. LoRa is designed for low power sensors in sleep mode most of the time.
Sharing six decades of knowledge in an easy to comprehend manner is priceless. Well done.
Thanks for the explanation. You filled in all the missing pieces of an overview. I like your methodical and paced explanation style.
Thanks Andreas, you've produced the best and most didactic introduction to LPWAN, and LORAWAN in particular, I've seen
Thank you for the "flowers"...
What a brilliant presentation. Well planned and executed. Kept moving at a good pace that was easy to follow. No umming or erring and no boring repetition. A perfect example of how it should be done. Many thanks for all the time and effort that must have gone into it.
The "umming or erring and boring repetition" was there, I can assure you!
your accent and speed speaking is excellent , even a french can understand you ! 👍👋💖
Thanks for your kind presentation.
For me, it was great to know that the relationship between bandwidth and range.
Yes, energy conservation raw is applied to all of things in nature.
You are right!
This is a new law to me. Narrowing bandwidth increases propagation without increasing applied power or modifying the antenna. Does this mean using NBFM over VHF would increase range rather than FM?
That said, I’m really interested in Encrypting CW as 150Hz is about the best and most open signal I can design. I was trying to build two hand-held communicators that exchange text messages between them using CW encrypted with a shared one-time-pad files on an SD card.
I’m struggling to find a license from the FCC, but I keep falling back on PLMR, but documentation of use and the licensing process make that license harder to confirm its candidacy.
Someone in a ham radio forum suggested Lora, but lora seems to be an entire standard like iEEE 802.11, rather than a band.
you are very skilled at starting the story from the perspective of someone unfamiliar with the topic and progressively leading them through discovery piece by piece
Thank you for your nice words!
Your video is very well made, incredibly informative and covered an interesting topic. It's rare that one can learn so much in 20 minutes. You've raised my expectations for instructional videos. I'll be more critical of others, including myself, to be as good as you. Thank you for taking the time to create and elevate this video!
You are welcome. I also had to go a way to get where I am. It took me 61 years ;-)
I can watch your videos 3 times, back to back, and still pull information from them. You are very masterful in your articulation.
Thank you for your kind words!
one of the clearer and information dense videos I found on this topic! I stumble on a couple of the topics you mention but with your video everything fall in to place and now i have the bigger picture. really good video, appreciate for sharing the info!
Thanks for your nice words!
You are not just knowledgeable, but also a great teacher. thank you
You are welcome!
Thank you for providing subtitles in Portuguese. sure your channel will be very successful ppis is now accessible to people who do not speak English well. I'll watch all your videos that have subtitles in Portuguese
The subtitles were provided by my viewers. But this project was stopped because it was too much work for my viewers.
I feel like all you blokes are the coaches I never had. Thanks for helping understand these concepts.
You are welcome!
Thank you for putting an axis description on your charts. There are way too many charts around with only the axes (if at all) and the some line or bands trying to show something.
And as always I learned a lot.
Definitively worth a subscription.
Thank you and welcome aboard the channel!
Andreas... WOW! Great explanation! I learned a lot! THANK YOU!!!
You are welcome. I had the advantage that I knew quite a little about RF before.
I have learned "Iot" too xdxdxdxd
Excellent video, thanks.
Perfect solution for sensors.
Such a pity the LoRa transceivers are so expensive compared to ESP8266.
:-)
Just found this channel - wow! Really interesting stuff covered here. I subscribed straightway! I have watched most of the LoRa videos and am now looking forward to your other topics. Thanks for such interesting content, you have inspired me to think of more projects for my RPis (5 so far!).
Welcome aboard!
You are such a great presenter. Please keep posting. I learned a lot. Thanks for your time and effort!
Thank you!
Thank you Andreas - I've finally caught up with things so I can now look at this technology. Great introduction.
:-)
Very interesting, and you are a very good teacher
Andreas, that is the most helpful overview I've seen about LoRa so far. Very clearly presented, thank you!
Glad it was helpful!
Yes I liked it !! Of course ! My dear Anreas with the Swiss accent... your very creative and an excellent tutor/teacher ! I'm now looking to set up my own gateway. I'll let you know how things are evolving.
Welcome in the club! It is not too complicated and I will make a video about how I did it.
This is an extremely useful video. Thank you for the info.
You are welcome!
Thanks - you are very good at explaining complex radio theories in an easy to understand way . I like your other videos also - it will take me awhile to watch them all !
You are welcome and I hope, you will enjoy them.
Dear Andreas,
It's a real pleasure to read your channel every week. Thank you for your great job. It's a source of infinite inspiration. I hope to build a gateway TTN near of Toulouse.
FCH
Thank you for your nice words. The neighborhood will like you for that!
This is the first time I've enjoyed a powerpoint presentation type of a video
You're a great explainer
Glad you enjoyed it! I use PowerPoint because I have the software ;-)
love it cant wait til next vid on this.
:-)
Yes. This is exciting! I think the advantages of this technology are very big. Especially when your project needs to be reliable. Like a water(leak) sensor in a house boat.
You are an excellent presenter. :-)
Thank you!
^^ Agreed
+SquareofPrimes :-)
Totally, it's the most information packed, totally to-the-point video I have found on this subject, well done, sir.
Yeah, I am 39, Mr Spiess always give me that honest, school teacher feeling. It's like I am learning stuff from a truly reliable source. Thank you Mr Spiess.
Thank you for this excellent tutorial! Your clear and concise explanations of how the technology works were very helpful, and I appreciated the level of detail you went into while still keeping the content accessible.
Thank you for your kind words!
One of the best tutorials I have seen on TH-cam. Thanks you !
Thanks!
Thank you for the information, very useful!
LoRa seems great, however, I think the relative high cost of the LoRa hardware is not in line with the IoT vision of having millions of devices deployed. It seems it makes sense to use LoRa only when long ranges are required, right? Because for smaller ranges, for example house automation, WiFi is more than enough, and we know from your previous videos that an ESP8266 can run on extremely low power and have long battery life.
1. I agree, cost has to come down, mainly for the sensor nodes
2. In house, usually you have WiFi and power. So, this technology makes less sense. There is one exception: If you want to run on batteries also in your house. I heard, that there are plans to integrate small gateways in normal WiFi Routers.
I guess production economies of scale would kick in, if LoraWAN usage reached a certain market penetration.
From a financial standpoint, I think building lorawan gateways are dirt cheap compared to building cellular network towers. And also yes, it's as you said, lorawan is for long-range iot use cases such as smart cities, smart metering, etc.
For smart homes, bluetooth and wifi is still the king.
many thanks for the excellent introduction to Lora, I would really like to see an esp client using low power without the wifi enabled to run the lora client with a temperature sensor etc. please sir!!
So far, I do not know if the used library works on the ESP
Please can you share links of the hardware you use / suggested for the gateway
sorry and the libraries :)
The hard- and software will be covered in future videos. There, you will find the links
Beautifully presented. Thank you sir! Most definitely the clearest presentation of LPWANs and LoRA.
Thank you for your nice words!
You are not only the great engineer - you are the great lecturer too!
Thank you!
@6:50 "The link budget is, as every other budget, something you have at the beginning and which you spend over time.
If your budget is used up, you cannot spend more. At least this is what we learned when we were young." I thought his was a very funny statement especially as debt is a big problem for adults worldwide.
I got a chuckle out of it as well
I have read some about LoRa but now you explain it in 20 min and i got the idea what's about. Thank you!
Btw. are you a licensed by BAKOM as a amateur radio operator? I will have my exam in the end of march for a "CEPT-Lizenz". Did you learn you CW-knowledge at your military duty?
1. Yes, HB9BLA, but not very active.
2. Yes in military (special forces). And later I worked for the International Committee of the Red Crosses (IKRK) as a radio operator.
3. Good luck for your test
4. If you want to learn morse, you have to build the "worlds best morse trainer" (my first 3 videos orso) ;-)
What was the special force service you served? Swiss Engineering infiltration and sabotage? Can you tell us without having to kill us for secrecy?
+Steve B I was a spy against the soviet union...
Have you ever visited the Suworow-Memorial in Uri?
I do not remember. Maybe when I was younger...
Thanks for the video. Excellent use of reasoning and examples really helped me gain some insight to the "why" of this tech in addition to the "what". Presentation and content on point.
Thank you! There is a whole playlist with LoRa videos on the channel if you are interested.
Well done Mr. Spiess. I have been reviewing all your videos on LORA. My parts are on the way to build my own gateway and start testing. We need a cheap way to measure flow conditions in ephemeral washes here in Arizona, USA. We have been using cellular modems and even satellite modems which can be expensive. LORA may be a cost-effective alternative. Thank You for explaining things so clearly such that even a non-electrical engineer like me gets it!
And maybe you find a hill somewhere for a small repeater or a gateway (via cellular). Then you could cover a quite big place with only one cellular connection
Very good. danke für all diese Videos. Sehr hilfreich. Gruss aus Berlin
Bitte, gern geschehen...
Hi Andreas, Nice Video, i'm trying to figure out how to use this for getting some data from agriculture, with the ESP i make a mesh and make a map with the rssi of every node of the field, and send the data to the server for handling it. With LoRa how i could achieved that?
BTW Excellent video... is there any chances to bring you to colombia? 🇨🇴
if you want a mesh you would need to convert 802.15.4 or other mesh protocol to use the modulation format. good luck with that
I'm so happy I found you, rare quality content on yt. May the ohm's law bless you Sir.
Thank you!
Brilliant description and a nice spectrum analyser too. And I haven't seen a sidewinder since I did some work for Interpol in Iran in 1976! The operator could recognise who was on the other end! The million miles per watt club again - now there's a link budget...
Thanks for your feedback! Physics doe not change, just the words we use...
Adreas, very didatic explanation. Thanks. I already knew few things of what you presented, but you presented in such didatic way that now everything is more clarified.
Thank you for your nice feedback.
It is June 7, 2020. I just worked through your lora meshtastic video. Now I am going back to review. Thank you for all your work.
Glad my videos are useful for you!
Thanks Andreas. One of the most informative videos I've seen in a while. Please keep the good work
You are welcome!
This was awesome information. I learned a lot about LoRa. It is much more limited than I thought, but it seems like it could still do the most important parts of what I am interested in. I am looking forward to future videos.
+Perspectologist To show also the limits was very important for me. This is very important for decision making. Especially if a technology is hyped...
Great Introduction to LORA! This video is part of the network and communication course at the California Polytechnic Engineering College. As a swiss student doing my semester abroad at CalPoly I enjoyed watching this video with the class. They found the accent quiet charming!
Cool. So we were able to export something to California. Thank you!
I am trying to get familiarised with this topic. So far this is the best understandable explanation. Thank you very much!
You are welcome!
You are God sent! I've learnt so much from your channel! Almost every subject that I was curious and googled about, you have a video for it! Thanks so much for sharing!! Keep it up!!
You are welcome! I plan to continue and hope, future videos will be as well interesting for you.
I have so much respect for people like you who understand this stuff
Thank you!
LoRa is one of those terms that I have heard here and there, but didn't know much about it.... Just that it has something to do with IoT.
This video was really helpful, teached the basics of LoRa very well! Thanks!
You're welcome!
Good to see you all really enjoying his LoRa.
I do enjoy all kind of wireless technologies...
Andreas, you´re not only a great enginner, that adores to know how the things work, but a great communicator with a high skill to transmit your wise and knowledge to everyone; thank you indeed for your great job in this channel, guy with the swiss accent ;-) (my spanish accent is not better, hehe)
Than you very much for your nice words!
You have done an excellent job explaining LoRa. Thank you very much!
You are welcome!
Gute Einführung in die Grundlagen dieser Technik. Basis um die Rahmenparameter zu verstehen.
Danke!
Thank you so much for this video, you saved a lot time to understand the Lora concept.
Thank you, Andreas, I really enjoy your presentation.
:-)
Really informative about what LoRa is and what is capable of doing with that. Also interesting is the 150€ concentrator board. Just started with that and ordered my two LoPy boards, ignoring the fact that I only have a nano gateway. That is enough for getting started and experimenting.
Thank you
+TheLollisoft You are welcome. Enjoy your experiments!
Excellent introduction! Just what I was looking for.
Obviously you have made a presentation plan before the video. And a good one too.
Thanks! There is always a lot of planning before I start recording...
Great presentation - appreciated the number of slides and other explanatory aids.
It really helped me start to understand application areas for LoRa and how it stacks up against other technology.
Already watched your point-to-point LoRa video (also a wonderful video) - which kinda filled in the device as used
in a 'non-community' context; which was more along the lines of my deployment thoughts.
Thankyou
Thank you! There is a whole playlist about LoRa. And on Sunday I will add a comparison to Sigfox...
@@AndreasSpiess Excellent - I've subscribed and going through the playlist. THankyou
Welcome on the channel!
Thank you, Andreas! Extremely informational and you explain things very well.
Thank you.
Wonderful, wonderful, wonderful - can't wait for the next installments. Thanks!
Thanks!
Thanks so much for this LoRa video. Can"t wait for the next in the series.
You are welcome. Still some work has to be done...
Great video, you provided a very informative overview of the LoRa technology. The chart comparing technologies and the details on how you calculate range were both very helpful as well. I'm looking forward to the next video.
+Alan Sloan There is already a playlist for other LoRa videos
Another first class explanation, wish you all the success you deserve.
Many thanks!
Very much informative for the beginner and to understand basic concepts of physical layer for IoT based on LoRa standard.
:-)
Great Explanation! Very Helpful tutorial for whoever wants to learn LoRa. Thank you for your effort!
You are welcome!
Thank you for that brief and very informative explanation of LoRa, I am now a new advocate
Welcome aboard!
That was even better than usual Andreas, well done! Concise but very rich with information I feel I have a good overview of the LoRa project, a result for a "man off the street"! Why do I see myself buying more modules, setting up community gateways??? Thanks again :)
Thank you for your nice words!
Very clearly!!! This substituted well my one hour topic from University. Thank you!
You are welcome!
Very well presented and very well researched. Thank you for this video, will definitely check out more!
:-)
I'm starting to know about LORA and in some minutes I could understand a little bit of this technology thank you Andreas
You are welcome!
Great video.
Waiting for the next video like to set up my own gateway.
Very interesting.
Nice Andreas! Lots of interesting hobbyiest projects that can be built with a Wemos D1 Mini, the RFM95 and TTN. looking forward to seeing more examples...
Thanks. I do not foresee the Wemos for that. Much to power hungry. Maybe an ESP-12 with deep sleep. But I do not know, if the library works on the ESP.
I really dig your accent man. I feel like I have Arnold Shwarzenegger in my living room. Thanks for this informative presentation. I will definitely be back.
:-)
Problem solved in few minutes. Thank you sir
Thank you for sharing your knowledge. The information and explanation is simply superb!!!. Please keep posting videos.
Thank you! As long as I have viewers it is fun to create videos...
Very good and informative video!
Huh, was wondering what LoRaWAN was, and all the "marketing brouhaha" is just making me suspicious, but your engineering-oriented presentation totally makes sense.
Thanks for making & sharing this, kind sir!
Thank you for your nice words!
LoRa seems likely to be a very important development in the world of IOT devices and networks.
I'm glad that you've chosen to cover this technology, and will be watching all of your future videos on this subject.
I hope to be able to deploy both LoRa gateways and nodes as the price of the hardware enters my (low) range of affordability. I'll be pleased if I can be the first person in my neighborhood in Reno, NV in the USA to have a functioning LoRa public gateway online.
The concentrators for the moment still are quite expensive. Maybe I will be able to build once a low cost gateway with only one channel. I do not know, if this is possible yet.
Certainly, even a single-channel gateway would be very useful in these "early days", considering the 100+ possible nodes that can share that channel.
Even being able to support a handful of nodes per gateway would be useful for those of us who simply want to be "on the air" and see where this is all leading to.
I found a link and I will try to build one.
Still the best video about Lora/Lorawan. Thanks!
You are welcome!
Very well organized and presented!! I am impressed with your spirited style.
Thanks!
Very informative video. I didn't know about LoRa. I'll be looking forward for the next part.
Thanks!
Agreed, since your videos I've watched atleast 5 in a row. Very informative !!
Thank you!
Merci, j'ai découvert plein de choses grâce à cette excellente présentation.
De rien!
You are an excellent tutor. Thank you for your expertise.
Thank you for your nice words.
Always really incredible work Andreas! Thank you
You are welcome!
finally, cool, thank you... it is most detailed explanation of lora until now...i am looking forward next...cool..
Thanks!
Looking forward for this series!
:-)
You are my mendor !! I am Watching you from Greece !! I want to learn enrything from you, so i can teaching my son. You are the best Andreas !!
Wonderful! I hope your son will be interested in the topics. too!
Bardzo ciekawy i nowy dla mnie temat. Obejrzalem z duzym zainteresowaniem. Dziekuje i pozdrawiam.
Zapraszamy!
I'm just getting into LoRa, so this was very useful, thank-you.
You are welcome! There is a LoRa playlist for the channel...
@@AndreasSpiess Thanks, I'm working my way through them.
i'm inspired to do a lora project myself now! thanks! great work!
Go for it!
this is so cool... I have to start building a gateway right away... thanks for the inspiration!
But it is not cheap..
Thanks, that was a great introduction to LoRa!
Thanks!
Brilliant intro of LoRaWAN. Thanks.
Glad you like it!
Always enjoying your lessons meine Herr 😎. Great explanation!
Thank you. Glad you like my content
Best video on LoRaWAN out there, thank you sir!
Glad it was helpful!
Very good video Andreas. It should be noted, LoRa has its roots based on previous generation technology radio as you pointed out. But it wasn't AM radio that spurred current development of LoRa but three forms of Packet radio which have been in used for about 15 years on AM / FM frequencies and more commonly, HAM radio, which has used packetizing of various HF, VHF and UHF bands such as 144.39 MHz in Europe and 144.80 MHz internationally. HF packet radio transmissions are on between 10.151.5 MHz (LSB) and 14.105.51 MHz LSB. It's bandwidth is something between 300 and 1200 baud! But it's advantage is the capability to transmit half way around the world. Packet radio has been around for over 30 years.
In the world of emergency disaster response, we have experimented with FM side band packet radio since 2005 that was initially developed in 1994 using X.25 packet protocol.
During World War II, Germany attempted to encode data blips over HF radio that could only be interpreted by a receiver that sent timed encoder signals to a tape strip, which were then sent to an egnima encryption machine directly without manual inputs. Little did they know that Alan Turing would beat them to it.... which to bring this conversation full circle, a digital Arduino / Raspberry Pi shield of the Enigma M3 version (8 Rotors & 2 reflectors) has been available over the last couple of years and is also available as a standalone IoT device.
Really enjoying your videos as of late. Many thanks for sharing your expertise.
Thanks for the things behind this new technology. We all stand on the shoulders of earlier generations.
