Using current GSM (2G,3G,LTE) networks for something like a battery-powered environmental sensor sending just a few bits, once in a while is probably not the most power and cost efficient.
Hence the creation and rise of better suited alternatives.
However, GSM networks worldwide coverage surpass by far those low speed IoT optimized networks today.
It's understandable carriers want to keep being the tech of choice for the explosion of IoT devices anticipated.
IoT pretender Ingenu takes bite at mobile industry
Backed by heavyweight industry figures, Ingenu claims to be building the first nationwide, wireless network in the US dedicated solely to M2M and IoT.
One thought on “This new initiative and +SIGFOX network already deployed and extending are probably why you hear current carriers talking about making 5G networks adequate for the Internet Of Things”
By far now, but Sigfox plans on having a worldwide coverage by 2020. Having played with Sigfox I can tell you the tech is outstanding. I didn't find a place where it didn't work yet and I've been in the middle of Jura(gsm didn't work), London, Barcelona, Brittany and Paris. Requiring much less antennas for the same coverage makes it easier for them. With 100 million in funding they'll sure expand even faster.
