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.

...when your device says "Hi" instead of "hello world" because you don't want to use too much bandwidth. :)

[@AndreasSpiess]

Yes. LoRa devices are very slow and do only have a very limited number of bytes to transfer.

Great video. No unnecessary talking face, but only relevant illustrations and clear explanations. This is how every single KZbin video should be and not only 0,0001%.

[@AndreasSpiess]

Thank you for your kind words!

[@johnhschuster]

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

[@AndreasSpiess]

Thanks for your nice words!

[@MrNams]

Can we broadcast message from one lora node to all other lora nodes without gateway?

[@Andrew-rc3vh]

@@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.

[@skepticon9390]

Sharing six decades of knowledge in an easy to comprehend manner is priceless. Well done.

[@pagutierrezn]

Thanks Andreas, you've produced the best and most didactic introduction to LPWAN, and LORAWAN in particular, I've seen

[@AndreasSpiess]

Thank you for the "flowers"...

[@johnb8753]

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.

[@AndreasSpiess]

The "umming or erring and boring repetition" was there, I can assure you!

[@BlueyMcPhluey]

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

[@AndreasSpiess]

Thank you for your nice words!

[@greg3626]

Thanks for the explanation. You filled in all the missing pieces of an overview. I like your methodical and paced explanation style.

[@Ikono-claste]

your accent and speed speaking is excellent , even a french can understand you ! 👍👋💖

[@jongman_kwon]

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.

[@AndreasSpiess]

You are right!

[@doomgod314]

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?

[@doomgod314]

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.

[@RickSaffery]

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!

[@AndreasSpiess]

You are welcome. I also had to go a way to get where I am. It took me 61 years ;-)

This is the first time I've enjoyed a powerpoint presentation type of a video You're a great explainer

[@AndreasSpiess]

Glad you enjoyed it! I use PowerPoint because I have the software ;-)

[@ModestMaker]

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!

[@AndreasSpiess]

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

love it cant wait til next vid on this.

[@AndreasSpiess]

:-)

[@RubenLensvelt]

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.

[@AndreasSpiess]

Welcome aboard!

[@Hackvlog]

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!

[@AndreasSpiess]

You're welcome!

[@brianlee9810]

@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.

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!

[@AndreasSpiess]

Cool. So we were able to export something to California. Thank you!

[@mikehudson3620]

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...

[@AndreasSpiess]

Thanks for your feedback! Physics doe not change, just the words we use...

[@brucejackson5898]

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!!

[@AndreasSpiess]

So far, I do not know if the used library works on the ESP

[@brucejackson5898]

Please can you share links of the hardware you use / suggested for the gateway

[@brucejackson5898]

sorry and the libraries :)

[@AndreasSpiess]

The hard- and software will be covered in future videos. There, you will find the links

[@DemetrisStavrou]

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.

[@AndreasSpiess]

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.

[@CraigMilesYoutube]

I guess production economies of scale would kick in, if LoraWAN usage reached a certain market penetration.

[@ValianTheRELover]

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.

[@afyu]

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.

[@AndreasSpiess]

Thank you for your kind words!

[@ericon.7015]

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.

[@AndreasSpiess]

Thank you for your nice feedback.

[@dl8cy]

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?

[@AndreasSpiess]

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) ;-)

[@AndreasSpiess]

I do not remember. Maybe when I was younger...

[@CRISAP94]

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?

[@CRISAP94]

BTW Excellent video... is there any chances to bring you to colombia? 🇨🇴

[@steveb7600]

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

[@ingsislra]

Thank you so much for this video, you saved a lot time to understand the Lora concept.

[@DougHanchard]

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.

[@AndreasSpiess]

[@DarronBirgenheier]

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.

[@AndreasSpiess]

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.

[@DarronBirgenheier]

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.

[@AndreasSpiess]

I found a link and I will try to build one.
