Earlier quoted context omitted.

What might somebody (or some company) use this for? 192 bytes * 750 packets = 144000 bytes per month at what speed/latency?

Weather station or any kind of remote sensor that you want to keep in some remote area.

Silence sense and FCC-required logging for a mountaintop broadcast transmitter.

I can't get to their documentation but it looks like it's using LoRa for the RF.

Pretty cool. Just checked coverage over my house using their pass checker and it's already ~50% coverage through the course of the day. No good for realtime alerting but good enough for daily reporting.

Under 150KB per month, $5. Under 300KB per month, $10. Under 450KB per month, $15. Up to 600KB per month, $20. Note, that's total number of bytes, not bytes per second.

With numbers like that, this seems completely useless except for all but the most wildly specific of applications

Minimum order of 25, so roughly $3725 for one year unless you get the "eval kit" @ $449. USD $5/MO PER DEVICE Provides 750 data packets per device per month (up to 192 Bytes per packet), including up to 60 downlink (2-way) data packets

Provides 750 data packets per device per month (up to 192 Bytes per packet) 144,000 bytes. Almost the capacity as a Commodore 1541 disk drive. 40 years ago it would have been unfathomable that a regular schmoe could transmit a floppy disk via satellite for just $5.

I love this type of tech and want to get in on that sweet 144,000 bytes of data at 5 per month, but... it's not just 5 per month, it's a minimum investment of 500 unfortunately.

Also, not sure where to find a decent Commodore system these days to utilize this plan :)

This is not affiliated with SpaceX if I read the site correctly. Super-interesting though. Edit: Wrong, see below

"View Open Positions" link points to SpaceX page https://www.spacex.com/careers/?search=swarm

SpaceX purchased them last year.

I worked on a project for a carrier focused on monitoring temperature of seafood (oysters to start) from water to store.

They were anticipating some legislation that would require full auditability of supply chain.

Curious how it compares to Iridium, I've seen those with Sparkfun

Sure, but 40 years have passed since then and 144K peanuts for any real world application.

A quick example, you have a sensor that sends a single metric every minute. Suppose that you can pack that info (sensor id, metric type and data) in 32 bytes. You're looking at about 1.2MB/month of data (8 times your 144K), which will come to about $40/month.

Quite expensive for a single data point, but I can imagine several use cases where that cost can be easily justified.

this is actually really great for applications like tracking, remote instrumentation, and other services that have a small amount of relatively important data in hard-to-service or critical applications which is not that wildly specific.
