I need to communicate (Send and receive) with a remote device with no cellular or radio network.
If I want to use Satellite Communication, is there any DIY component and low-cost Satellite data provider?
Please suggest any alternative considering the location of the remote device is in the sea.
Can you define low cost ?
Check with Iridium, Inmarsat, Globalstar or Starlink.
That won't come very cheap though - multiple hundreds of dollars per month probably.
This is a popular setup:
Total cost depends on message volume.
Line rental costs £12GBP (about $15USD) per month and includes access to the Cloudloop management system for managing your devices.
Thanks did not know that one
Did anything come of Swarm ?
Swarm has been subsumed by Spacex/Starlink. The original company was fined for illegally launching controversial satellites: Swarm Technologies - Wikipedia and not much has been heard since.
Sparkfun discontinued their offering: Satellite Transceiver Breakout - Swarm M138 - SPX-19236 - SparkFun Electronics and a Sparkfun forum user posted this note not long ago:
Did not renew service with Swarm in May this year due to high latency. Sunspots damaged many satellites and latency for transmission about 12 hours. My M138 unit now gathering dust. Successfully operated unit for 1 year. In my one year test, did a binary data transmission for about 6 months (weather plus solar charge controller data) and a json data transmission for about 6 months (weather only). Looking forward to the IoT option with direct cell to satellite (2025).
I have contacted with Ground Station team and got this data plan:
The 5kB data allowance is the amount of data a device is allowed to use per month, so your messaging total will need to be under 5kB per month to avoid getting into overage charges, which are usually charged per additional kB.
That is too much cost to effort. Can anyone explain to me the total monthly package and charge in summary?
