Hello.
I was looking for a Sub-1GHz module to play with and make a simple IoT application like home automation.

Few months ago I found a new chip come from Texas Instruments, CC1310. This chip incorporates a Cortex-M3 and a Sub-1GHz radio in a single QFN package.
I decided to make a simple and tiny module, something more like a breakout board but the final product was very expensive even in large quantities. I managed to build one board even though the cost was little high to afford it.
Due to high cost I was trying to find a module made from another company that might would be of course much more cheap than mine.

I came accross many modules and terms, LoRa, SigFox to name a few and few modules with CC1310. All of them with very competitive price as I predicted.
As I delving into them, I have to admit that I'm a little confused about the comparison of those terms and modules.

First of all I do understand that LoRa is a modulation technique.
I'd like to ask what's the advantage of TI's CC1310 in comparison with LoRa modulation (semtech's chips) or other Sub-1GHz chips?
What about SigFox?
Apart from integrated ARM Cortex-M3 in the TI's chip, Is there any advantage in range or power consumption?

Thanks in advance

 

From specs LoRa chip has lower Sensitivity compares to TI's CC1310, the lower the sensitivity, the weaker the signal it can pick up. So lower is better.

SigFox vs LoRaWAN/LoRa
it's their business model. If you use a SigFox module, you have to subscript to their service. It mean ongoing cost. Like you buy a mobile phone and also need to pay for the service.
Semtech is a chip manufacture, their interests are in selling chips. That means you can use LoRa as point to point connection. Setup your private LoRaWAN network. (no ongoing cost) Or subscript to a public LoRaWAN network (ongoing cost). It's open source, so if you want, you can build your LoRaWAN module if you like.
