High Throughput LoRa Gateway

Development Tools Cloud IoT
1

Hi all,

I am working on a project that needs to take data packets from 1000+ nodes and post them to MySQL database.

The nodes will transmit 100-200 bytes ideally every 30 seconds but that could be every minute if needed to reduce the amount of packets.

My questions are

  1. What gateway could handle that throughput?
  2. What happens when the gateway receives 10 packets at once? Does it queue them or just drop them?
  3. Will the node receive a confirmation of it's packet been received by the gateway?
  4. Can I assign each gateway to a different groups of nodes? (there could be up to three groups of 1000+ nodes and I want to make sure that there is no overlap in the database which would also cause a general slowing down of the system)

Your knowledge would be much appreciated!

Kind regards, Zeb

They are ignored.

LoRa is specifically designed to be low throughput, and regulations are there to enforce that.

Interesting, so what communication technology is out there that is long range, large throughput? What are the regulations? Where can I find them?

Thanks, Zeb

The portions of the radio spectrum that you may use depend on your application, and whether you are a private, commercial or government entity. Rules vary from country to country but the bands are assigned by international agreement.

For legal advice, consult a lawyer with the appropriate background.

Unfortunatly just because you 'need' to process packets of 200 bytes every 30 seconds from 1000 nodes with acknowledges does not mean it is legal to do so, or that the hardware exists to make such Gateways possible.

So further discussion seems rather pointless.

Maybe if you reveal to the forum what the project actually is, where it is, the distances involved etc, you might be suggested workable solutions.

Cannot see how anyone can answer that, you seemed to have assumed the forum knows the environment you are running this project in and what you mean by 'long range'.

Considering the cost of a 1000 node project, it would be an assumption that a few more details were available.

As for the regulations that apply to your country just contact your regulator.

And just as important, how big is your budget and how long is your time frame? Why do you expect a hobby/teaching forum to be able to answer your industrial size questions?

are the 1000+ nodes based on a single site communicating with a local server if so using 1000baseT Ethernet could work.
if a distributed system equiping each device with a GSM modem communicating using MQTT or a similar protocol may be a possibility
