- In this video, I will appear on stage and will talk about LoRa propagation, antennas, range, and other interesting stuff. I also will show how you can simulate the range of your LoRaWAN gateway.
This session was taped in Hyderabad, India, where the Asian LoRa conference with 800 attendees took place.

"Longer is not always better" - the guy with the Swiss accent.
main take away from this awesome talk 😊
Most comprehensive video on LoRa and basic concepts like spreading factor is explained well in terms of application part.
It's great to have such knowledgeable industry experts like you on TH-cam!
Thank you for your nice words!
You are an awesome teacher and I am a front row fan of yours. Your curiosity is infectious and there is so much to learn from your experiences. You were in my country talking about a subject you have such a strong grasp. Radio is fascinating and much of the younger generation born with a cell phone in theirs hand takes for granted. Ham radio too is sadly negatively impacted.
I agree. But still it is valuable to understand the laws of wireless. Maybe it becomes more valuable if nobody understands it but everybody needs it ;-)
You are awsome, incredible skills, speak different languages, well travelled, willing to teach. etc.
Thank you for sharing your incredible skills
👍👍👍👍👍
I live in a very small country. So we have to speak different languages and sometimes travel to our customers;-)
@@AndreasSpiess Swisserland is small in size but it has 4 different languages. And as you said in your video "Size don't matter" ;-)
Gratuliere zu diesem Vortrag! Ohne komplizierte Formeln auf den Punkt gebracht. Mann/Frau stellt fest, der Redner ist hochkompetent.
Auf Berndeutsch: Merci viu mau!
Vielen Dank! Und einen guten Rutsch.
I miss the little hand on a stick. 😁
They did not invite the president of an important county, they invited just me ;-)
My compliments, excellent presentation, Andreas.
Thank you!
Fantastic speech, I am a computer science student on Spain and I enjoy your videos quite a lot.
Thanks!
You are welcome!
Glad to see you on camera in a video, you are charismatic and likeable, you should do more videos with yourself in it!
Thank you. The effort is too high. My lab is very small.
I am from India!
Very pleased to see you that u were in Hyderabad (summarised)!
:-)
Congrats Andreas! You are a celebrity TH-camr now! Pleased to see that the whole conference keeps the channel style 😊
:-)
Thanks for the great video Andreas.
I have tried to watch other videos from the conference and had to stop.
The presenters were talking about their subject via the video display behind them, however in the other videos we never got to see what they were talking about on the screen.
Thankyou , Thankyou for a professional presentation.👍👍
I got this presentation more or less ready-made. So I obviously had the nicer "helping hands"....
Setting the record is awesome but your I think this channel is a much more significant contribution. Loved the presentation, it looked like you were having fun.
Yea, we were a nice bunch of people....
What a great talk. I learned so much from this one presentation. Thanks so much.
You are welcome! You find many more videos on those topics on this channel...
Even on the front line you are an amazing talker :) Congratulation!
Thank you!
You are awesome sir you've blown my mind great and extreme stuff in 25 minutes.... I am an electrical undergraduate student. From diploma on wards i have worked on lora modules currently i am researching on it. Your videos helps me so much
Thank you. I am glad you find my videos useful!
Great talk, thank you Herr Spiess.
You are welcome!
thank you Andreas Spiess, the excellent presentation
You are welcome!
Great job Andreas!
Thank you!
love this man. Respect 🙏🙏🙏
:-)
Very good conference, God bless you
Thank you!
Thanks sir, very useful information!, greetings from México☺
You are welcome!
18:50 "This is the proof longer is not always the better" :D audience don't get his jokes..
Yeah, he cracked a number of jokes. Nobody laughed. It was a shame how dead the audience was.
@Li Feng Aww bummer. Well he should know I laughed.
@@ihatepokemonthings Dear, There's more rapes happening in New York or London than in entire INdiA.
I lived in London for more than 3 year.I knew people scared to get out after 7pm in most of areas ..there is no areas like that in Entire India.
So get rid of the wiked racist mindset you ugly moron..
@@ihatepokemonthings Hey man. Get your facts right. Per 100,000 population, on an average, India has 1.8 rapes, UK has 17 and US has 29 every year. en.wikipedia.org/wiki/Rape_statistics
Very well explained👏
Thank you!
Great presentation as usual. By the way... i had managed 2yrs back to get LORA connection max 200-300m with lora transmitter kept in small room inside building.. and i could get reception in another building in small room. So apparently concrete is big issue. But nevertheless i was delighted as i wasn't expecting anything... ;).
You did the right thing: Test it!
Thank you for a wonderful explanation of lora and it's use.
You are welcome! There is also a introcution video if you need more.
Nice presentation. Great presentor!
:-) Thank you!
Thank you for this great video!
You are welcome!
Thank you very much for sharing your knowledge, excellent presentation on the subject, thank you
Glad it was helpful!
Great speech/presentation with your, by now iconic, phrase 'Guy with the Swiss accent', but this time at the end. Now the indians know where Switserland is situated !
Philip Gevaert and maybe they will even learn how to spell it correctly sooner or later. :)
They kow it well because of the Bollywood films ;-)

Great Video as always
Thanks for sharing :-)

Wow. awesome talk. Thanks
You are welcome!
Wow... Welcome to our india sir

Congrats, great speeks
Thank you!
Thanks for these videos! You help me think up new possibilities.
Silly LoRa question if you have time to answer (thanks so much in advance!):
Challenge:
I’d like to place several small displays in a nonprofit silent auction, showing the current bid of each item on tables in one or more rooms. WiFi would likely not be great for these devices as there are a lot of people in the room also using WiFi on their phones where bids will be happening. It also eats up more power. If something gets placed outside the room, maybe not best for range. These devices also just need a little bit of data, not a TH-cam stream...
Would LoRa be a potential fit for something like this? As I type, the biggest issue I see is a bunch of people in a room. Will that likely block the signal? The other challenge I see is 30 or so devices in a room listening for their bid change announcement. I guess the broadcasting device will just rotate through what’s listening and each device discards messages intended for other devices.
Thanks again!
(will test, might be good for short distances?)
Maybe you have a look at my lora point to point video. Yo need a two way communication to deal with unavoidable collisions.
Absorbed! Thank you sir! :)
I swear I met his doppelganger in NZ a few years ago!
I look like many other people, so it is well possible. Happens here, too.
Hi from the netherlands!
:-)
Lovely clip!
Many thanks!
I am happy i didn't miss main presentation... i had to cancel my visit last minute
:-) This was just a short presentation on day2
Oh, wish I had known bout this conference 😮
Long time ago...
Excellent presentation Andreas, very well explained broadcast concepts. Can we get a link for that coverage prediction software you use (or is it a website?).
It is in the description (now)
Superb!
Thanks a lot!
I am from Hyderabad, didn't know that you were here.
I published it on Twitter
Well done!
Thank you!
200km? Damn, I wish I had a Swiss accent!
lol!!
Maybe it would not be not sufficient ;-) But it helps beause of the special situation around here.
Welcime.to INDiA Sir...Hope you enjoyed the temperature there..,😊
Nice presentation 👍
Ydes, the temperatures were very nice, compared with Switzerland end of October!
Hey! Mr.Spiess, thanks for the selfie that day!

You are welcome! So this video was not new for you!
@@AndreasSpiess No Sir, not at all! Infact, I understood all the references of your videos that you talked about!
I am seeing this now ?! Hope you had a pleasant stay in India
I had. Very nice people!
Congrats on speaking!
Thank you!
Inspiring video
Thank you!
Thanks for your effort and good work as always Andreas. It was interesting to see you "life".
Do you mind telling us what software you referred to at 16:30 ? You said it is free software?

I googled and found cloudrf.com/LoRa_planning
I put the link I used in the description
We are looking at data and voice transmission over 5 kms in jungle terrain and built up areas without loss.
Gentlemen and ladies HELP required!!!
Always look for line of sight!
Sounds very good. Things are coming to mind (but don't come out yet)

Thank you!
Man you're my favorite , i was in india , i soo wanted to meet you
I was available the whole two days at the conferene...
@@AndreasSpiess 😅i actually wasn't able to make upto the conference because i couldn't afford ...
But i would love to meet you someday in person !
Thank you!
You are welcome!
Hello the guy with the Swiss accent!!! Welcome to India, hope you enjoyed the Hyderabadi biryani. :)
Of course. And in the best Biryani restaurant!
Hi Andreas and others. Which LoRa end node (dev board) would you recommend to a beginner (e.g. dragino shield, TTGO), if one takes into account the price-performance view? Thank you.
They all use the same chip. If they are done ok there is no performance difference. I have some videos about the topic.
Almost as good as the Reading version 🏴😁 You look very relaxed Andreas👍
I was surprised when neither audience clapped when he mentioned his world record. (I had a camera in my hand at the time).
possibly because audience knew it already from the youtube videos ! just a guess, i was not there :( i made this comment because both of you are the oldest subscribers, i guess :)
@@dd0356 It would have been courteous and friendly - noting his incredible achievement. We were planning a slightly longer one here in the UK - and it's not easy.
@Richard: I am sure you will get it done. You have great people there...
@Dean, I left out the "UK flavor" and added some "Indian flavor". But I cut it out for this video because it was off-topic.
Nice.. interested!!
:-)
What simulation program you used for the radio propagation? You said it was free of charge..
The link is in the description (now)
Andreas Spiess thanks for fast reply:)
Where is written that connections above 100km are limited or not shown in ttnmapper or did I get this wrong?
No. You have to talk to the inventor for an exception;-) and in experimental mode there is no limit
@@AndreasSpiess Ah, that's why. Thanks for the feedback.
Most interesting. I need a WiFi link spanning some 3 miles ( 5Km ) out of town. Must be a way to use this to extend WiFi to my location ? Repeater of fashions ? Repeating any and all open WiFi Gateways. McDonald's et all ! I have a paid ISP but in cases it goes down I would like a somewhat dependable back up Internet Gateway established. What would be required ?
I am no specialist in WiFi. AFAIK there are special repeaters with antennas available. Never tried them
@@AndreasSpiess Actually thinking that route. Need someone halfway to allow me to set up a repeater. LOL
Do you have a link for the Lora distance calculator?
It is in the world record video
Hello Andreas, my congrats, I'm using radiomobile to predict my gateways coverage but not sure about input data, tx power rx threshold, any example? Using rak2245 pi hat, 6db antenna
No big problem. Just use a few watts and a very high sensitivity. The range should always be limited by obstacles. Then your values are ok.
I wish I had a chance to meet you. Fu$# my exams 😭
Same here, shittttt!
I hope they went well.
congratuiation
Thank you!
thx u sir..
You are welcome!
Heiderabat, the place where you get the best bargains! Every Swiss will understand.
Of course we tried it several times!
big fan (also with swiss accent & residence ✌️) is looking for a solution to control an ac (~80-230V multi-step) transformer with a 3.3/5V signal (Rπ) to control fan speed(s) based on logic/sensor data. I can find cheap manual transformers but nothing that accepts a signal input for control?!? Any help or hints would be highly appreciated and repaid with a voluntary one day assignment if you're ever in need of a second camera man or guinea pig to test your creations on!
This is not a simple problem, I think. Maybe somebody else has a similar transformer, or you find a project with a similar component using google. I do not have such devices around me, sorry. But no problem if you anyway want to have a short visit. You know how to find me...
20:02 - what website (or software) is this one?
You usually find the links in the description of my videos
i wish i could have meet you
fan form india
Maybe next time?
U came to India!!!...😭 I missed a golden opportunity 😭
And I liked it!
Nice talk! Are you planing to attend any conferences in switzerland?
Propheten im eigenen Land... Maybe. I once was invited to the Makerfair in Zurich.
@@AndreasSpiess the one in 2018?
I think so if I remember right. Or even 2017
@@AndreasSpiess you have at least 1 fan in deinem eigenen Land
Not bad, pretty good presentation.The negative viewers are probably using Zigbee lol.
And are disappointed when they do not get 200 km ;-)
Is Lora a modulation scheme? Or what kind of modulation does it handle? Technically
There are some videos about re-engineering the protocol. It uses chirps.
Hello master! what kind of gateway do you use for the world record??
I do not know. It was not mine.
hello sir, i want to work on lora communications. Can you please suggest me the cheap and best lora module?
I made many videos about LoRa (and others exist, too). Maybe you watch a few of them and chose a project that interests you. Then you see which board is good for this particular project.
Teşekkürler.
Desteğin için teşekkürler
Sir please share whenever u visit India also try to arrange a get together with your Indian fans 😉
I published it on Twitter. But I am sure we will find another possibility
Is the LoraWan Home Receiver STRICTLY a Receiver and Transmitter or JUST a RECEIVER ?
They are all 'half-duplex'. This means that they are both transmitters and receivers but not simultaneously. (Transmission is limited to a very short period compared to reception).
If you do not use LoRaWAN you are free to program one as transmitter and the other as a receiver. I made once a video about that.
👍
Thank you!
First from india
,
:-)
Cooler Gastauftritt!
Danke!
Erst liken, dann anschauen...!
Genau! Danke.
Wow, Hut ab! :D
9:15 But the receiver would also transmit, no?
Depend on your sketch
@@AndreasSpiess Hmm yeah, a sensor could transmit to a receiver, that would be unidirectional. I was thinking about wifi and so, which is always bidirectional
It seems odd not seeing white gloves on your hands 😉
:-)) Would maybe have been a little strange..
I am from india

@@AndreasSpiess we allways support your youtube channel Andreas
Let me tell you something Andreas: they did not appreciate your jokes 😂😂😂 you almost went to the moon 😂😂😂 size matters 😂😂😂 any flat-earthers? No? 😂🤣😂🤣😂🤣🤣 🤦🏻♂️Gruetzi (with a Genfer accent) from Redmond, Washington 😏
I learned that jokes are very local. Most jokes unfortunately do not work on a global scale... Greetings to Redmont!
First from Wales. I noticed a sub-agenda.
What sub-agenda?
19:30 No applause :(. Are the guys sleeping or digesting their chicken masala?
Congrats
:-))
Man I like your videos and the knowledge you share, but the humor in this video - WHOOF... I can promise it won't age well
:-)
didn't recognise you without the hat!
No problem. Now you know why I wear a hat on TH-cam ;-)
Is ur subscribers sitting in first raw there?😛
Not all were subscribers before. I hope, all are afterward ;-)
Andreas Spiess 🙌🏻
18:53 hehe

6:50
??
@@AndreasSpiess nothing sir, that's just my note 😅😅😅
Great video and great conference. The jokes about wives are a bit sexists. In a country where women are so often victims as in India, you really might have refrained to treat wives as scientifically ignorant. I know that you were joking and I'm sure you do not think that women are not equal to men, I just think it wasn't appropriate.
i guess you don't have an indian wife. she has mastery over and controls science, physics, biology, economics and pyschology.
Almost got downunder.
Still a few hours to fly ;-)
We need LoRaNanoSat 🤔
Maybe you watch the videos about LoRa satellites in this channel?
So Hyderabad is OK, but Friedrichshafen is too far :P
Maybe too cold🥶
Good point. My point: AFAIK i did not get an invitation to speak in Friedrichshafen ;-)
@@AndreasSpiess I bet I could find you an invitation to speak in the US (as long as no money was involved - invitations are cheap :) ).
