Satellites for LPWAN
Thank you for the article. What about the role of satellites in LPWAN? Can an LPWAN satellite network compete with the existing LPWAN solutions?

Re: Ten years?
It's not the battery per see, its the radios on the devices sucking down the battey life. As I see it, there's 2 reasons this gaggle of LPWAN technologies has come about now.

1/ Old 2G networks are being shut down, so operators and providers have uncertainity that the M2M connnections they've used before will even be available for the lifespan.

2/ LTE would be the logical choice as the replacement. But LTE as it stands is not engineered to support ultra-low power radio connections, as you can probably tell from how long your smartphone retains its charge. 

Hence a flood of LPWANs, to which you can add NB-LTE to the mix.

It's basically a game of two sides though: Improve the radio power consumption and improve the batteries.

Re: Ten years?
This does suggest the question whether battery life is also going to be a problem for IoT. Do we need 10-year batteries? Do we have them?

Today I learned AA batteries were invented in 1907.

Re: Ten years?
Thanks for reading and commenting, Mitch. I absolutely agree that LPWAN is just another instance of the "basket of remotes" problem plaguing IoT. Your question about a standard AA battery lasting 10 years is also valid. I believe the AA battery language is chosen in order to provide context on battery capacity in a way most people can relate to as opposed to saying something like 10 year battery life on a 2000 mAh battery.

Ten years?
A standard, off-the-shelf AA battery will continue delivering power for 10 years? I did not know that. 

LPWAN is another instance of the "basket of remotes" problem pervading IoT.
