No that would not - DC’s are set by law! Please read up on LoRaWAN…perhaps check out the You Tube videos on TTN Channel - esp Johan LoRaWAN fundamentals…
I have checked or watched every single source about Lora. I won’t use chirpstack or ttn as a gateway. We have a custom created gateway and we tested sending at 868 MHz using Lora class A end node. Now, we just want to send it more frequent. Doesn’t the end node trigger transmission from the end node? And there will be only one end node, so the line will be empty as long as our end node is not transmitting. what is there to stop me from not waiting the duty cycle period till i send another packet???
Then its an off topic discussion for this TTN forum.
The scenerio is as seen below. I want to read temperature data using LSN50 V2 and send the data to another lora end node every 500ms (at least). I’ll be using Class C end node both side. Energy consumption is not an issue. What is there to prevent it to get to that speed?
Hi, That is still not TTN LoRaWan,.
I dont want it to be TTN? I am asking about Lora’s capability.
This is a TTN forum. I am just an amateur, and the moderators are volunteers.
Then an off topic discussion in this forum which is for TTN …
That would be illegal as in breaking the law. The maximum airtime allowed in the 868MHz band is 1%. So not possible. Also you are using a shared medium with long range technology so that would be very anti-social as other users up to 100km could be impacted by your continues use of the frequency.
For this update rate you should use a different technology!!
A good starting point, to work out what is possible\legal, is to download the Semtech LoRa calculators.
A very good understanding of reception conditions, location, environment, antenna types and location, legal power restrictions and propagation is needed, before assuming you will get ‘10km’.
It won’t be used in a public place and there is nothing illegal about my circumstances which I cant tell. So nothing to worry about. I was asking if it was possible. It is possible, since I won’t be a part of TTN or Chirpstack and I’ll be using a custom cloud technology.
Apart from all the other perfectly accurate comments about you breaking the law, breaking the Fair Use Policy and trying to discuss an application that is off topic for this forum there is one other challenge you face.
The LSN50 is programmed as a LoRaWAN device - so you will have to develop the firmware for it to do the illegal transmissions your are looking for.
By illegal, we are referring to the police, courts, fines possibly even jail - as almost all countries have laws saying how much airtime you can use - not some academic “it’s private, not a public place” - radio waves travel far and wide - that’s why they are so useful.
Plenty to worry about.
Cannot think of anywhere in the World where the duty cycle restrictions (normally 1%) only apply in ‘public’ spaces.
So where in the World are you ?
The OP is in Turkey, but I think we’ve adequately replied to this topic for now - I’m going to put this on slow mode so if they or anyone else has something sensible to add it has one last chance.
This means, @sudeozan, you won’t be able to reply quite so quickly - hopefully you’ll consider the answers you’ve been given as it seems a bit pointless asking questions.
Radio signals don’t care about public or private places. Unless you use heavy duty RF shielding and place both the transmitter and receiver withing the shielding (which won’t work with 10km range) your use will be illegal.
Okay i got it, it is about breaking the Fair Use Policy. I will tell my department about this. Thank you.
Yes, that, but more importantly, you would be yasaları çiğnemek.
It is about reading the information we posted:
breaking the law
Nothing to do with FUP now as what you are now suggesting is LoRa p2p - outside scope of this forum and outside scope of TTN. What you are looking at is an abuse of the radio spectrum a shared social resource…Your signal can potentialy travel a long way - its LoRa, right, so you will interfer with and disrupt other RF users many kilometers, many 10’s of kilometers away. I know personally that the Turkish authorities, especially the military, take a dim view of people abusing RF technologies…the key question is therefore do you or others in your department kelepçe takmayı sever misin ?
And what temperature do you need to measure that is going to change with in 500mS?
You need to teat something with a blow touch to see that a sharp temperature gradient.
This is a temperature sensor badly placed getting direct sun in the afternoon. Measuring every 10min, reading every 500mS will tell you nothing more.
