Sigfox always struck me as a bit odd - LPWAN combining the downsides of cellular (relies on paid-for infrastructure) with the downsides of LoRaWAN (unlicensed spectrum; no real downlink to speak of).

The Freaks did not chip in enough to buy it?

If you don't know my whole story, keep your mouth shut.

What would be your choice for IoT? Just out of interest... Last time I checked(right at the beginning of the Corona pandemic - the Chinese company making the LoRaWAN modules we were using disappeared in support terms for a couple of weeks), NBIoT was pretty much a non starter in the UK, and LoRaWAN requires gateways.

Four legs good, two legs bad, three legs stable.

That's way too broad to give a single answer - it depends entirely on project requirements.

 

LoRaWAN requires gateways.

(pretty much?) all LPWAN options require "gateways" of some sort.

 

A potential advantage of LoRaWAN is that you can just buy (or make) your own - you don't have to rely on 3rd-party infrastructure.

 

With Sigfox, it is (was?) only Sigfox (or their local operator) that could supply & install gateways.

 

Similarly, the cellular options require coverage from a cellular operator.

 

NBIoT was pretty much a non starter in the UK

Depends where in the UK you are - there's an East/West divide between NB-IoT and LTE-M

Yes, but with NBIoT, for example, there's a chance the "gateway" already exists. With LoRaWAN, not so much.

Well, whatever network you choose, you're at the mercy of their coverage.

 

My point being that, with LoRaWAN, you can provide your own gateway - but you can't do that with Sigfox or any of the cellular options.

 

In fact, with TTN, you can provide your own gateway and still use the rest of their infrastructure.

 

 

(other LoRaWAN networks are available - I don't know if they are similarly accommodating)

Indeed. That was what my client did.

and, when they don't need the infrastructure, I've had clients just use something like this:
