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

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

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

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.

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

You are not just knowledgeable, but also a great teacher. thank you

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

I feel like all you blokes are the coaches I never had. Thanks for helping understand these concepts.

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.

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

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 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 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

Andreas... WOW! Great explanation! I learned a lot! THANK YOU!!!

I can watch your videos 3 times, back to back, and still pull information from them. You are very masterful in your articulation.

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!

Excellent video, thanks. Perfect solution for sensors. Such a pity the LoRa transceivers are so expensive compared to ESP8266.

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 such a great presenter. Please keep posting. I learned a lot. Thanks for your time and effort!

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!).

Very interesting, and you are a very good teacher

This is an extremely useful video. Thank you for the info.

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.

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!

Thank you Andreas - I've finally caught up with things so I can now look at this technology. Great introduction.

@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.

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.

Andreas, that is the most helpful overview I've seen about LoRa so far. Very clearly presented, thank you!

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!!

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.

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

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.

love it cant wait til next vid on this.

You are an excellent presenter. :-)

Beautifully presented. Thank you sir! Most definitely the clearest presentation of LPWANs and LoRA.

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...

Very good. danke für all diese Videos. Sehr hilfreich. Gruss aus Berlin

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?

One of the best tutorials I have seen on UKposts. Thanks you !

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!!

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?

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

You are not only the great engineer - you are the great lecturer too!

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.

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.

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.

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!

Gute Einführung in die Grundlagen dieser Technik. Basis um die Rahmenparameter zu verstehen.

I'm so happy I found you, rare quality content on yt. May the ohm's law bless you Sir.

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!

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.

Thanks Andreas. One of the most informative videos I've seen in a while. Please keep the good work

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

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.

Good to see you all really enjoying his LoRa.

I am trying to get familiarised with this topic. So far this is the best understandable explanation. Thank you very much!

I have so much respect for people like you who understand this stuff

You have done an excellent job explaining LoRa. Thank you very much!

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

Thank you, Andreas, I really enjoy your presentation.

Thank you, Andreas! Extremely informational and you explain things very well.

Very well presented and very well researched. Thank you for this video, will definitely check out more!

Wonderful, wonderful, wonderful - can't wait for the next installments. Thanks!

Excellent introduction! Just what I was looking for. Obviously you have made a presentation plan before the video. And a good one too.

Very well organized and presented!! I am impressed with your spirited style.

Great Explanation! Very Helpful tutorial for whoever wants to learn LoRa. Thank you for your effort!

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.

Another first class explanation, wish you all the success you deserve.

Very informative video. I didn't know about LoRa. I'll be looking forward for the next part.

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)

Very much informative for the beginner and to understand basic concepts of physical layer for IoT based on LoRa standard.

Thank you for sharing your knowledge. The information and explanation is simply superb!!!. Please keep posting videos.

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 so much for this LoRa video. Can"t wait for the next in the series.

Very clearly!!! This substituted well my one hour topic from University. Thank you!

Great video. Waiting for the next video like to set up my own gateway. Very interesting.

I'm starting to know about LORA and in some minutes I could understand a little bit of this technology thank you Andreas

Bardzo ciekawy i nowy dla mnie temat. Obejrzalem z duzym zainteresowaniem. Dziekuje i pozdrawiam.

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 :)

You are an excellent tutor. Thank you for your expertise.

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

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.

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.

Thank you for that brief and very informative explanation of LoRa, I am now a new advocate

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 !!

Great video Andreas! Clear, concise and very understandable :) Can't wait for the next LoRA update.

This is awesome, very excited to learn more from your upcoming videos :)

Always really incredible work Andreas! Thank you

Always enjoying your lessons meine Herr 😎. Great explanation!

You covered this very nicely, thank you! I look forward to consuming the remainder of the series and setting up my own gateway. This is the answer to reliable communications for my solar powered mailbox "tampering" sensor at the end of a LONG driveway. WiFi isn't cutting it and I don't want to do a custom 433MHz protocol. Being MQTT-friendly, this is perfect! :)

Problem solved in few minutes. Thank you sir

Excellent; Good explanation...

this is so cool... I have to start building a gateway right away... thanks for the inspiration!

finally, cool, thank you... it is most detailed explanation of lora until now...i am looking forward next...cool..

Agreed, since your videos I've watched atleast 5 in a row. Very informative !!

Sehr sehr schön dargestellt das Thema LORA, ich freue mich auf die nächsten Videos mit vielen Projekten zu LORA :-)

Great explanation, very simple to understand. Sharing with others.

Thanks, that was a great introduction to LoRa!

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!

Still the best video about Lora/Lorawan. Thanks!
