I covered this in a separate piece on low power wide area networks http://www.slideshare.net/haystacktech/the-iot-hunger-games-... though to be clear, we are not talking about high bandwidth like Ethernet. We are seeing good signal propagation in sub-1GHz bands (measured in miles) while preserving multi-year AA battery life with some newer PHY layer technologies like LoRa and others. 2.4GHz is a mosh pit that most serious IoT vendors are fleeing due to the high interference and the resulting RMA's and related costs. For sensor networks, there is rarely a good reason not to use one of the more popular sub-1GHz bands 433/868/915 regardless of your geographic location.

Your sales hyperbole is drowning out the good points you have. Knock it down a notch.

2.4GHz is a mosh pit. However, nobody is going away from it precisely because you need it to bootstrap the network. Data is most useful when it hits the internet, and, for better or worse, the only cheap way of doing that is WiFi with the occasional side of Bluetooth Low Energy with an attached phone/tablet/etc (however, people get annoyed at the extra battery drain).

Now, if you convince Apple or Google to throw 433/868/915 chips into all their devices, then, yes, people will dump 2.4GHz like a hot potato.

Good luck, but I won't be holding my breath.

"2.4GHz is a mosh pit. However, nobody is going away from it"

Nobody strikes me as hyperbole, really. You will see one of the two companies you mention embrace sub-1GHz in the next 6 months. Also LPWAN's are almost entirely driven by sub-1GHz now and the list of participating telco's are not nobodies.

I found some of your claims a little hard to believe. 1km+ range behind walls?

Do you have any test data to confirm this? Is there a device that can be acquired that has implemented your specification?

It is a feature of using lower frequencies together with lower data rates and signal processing technologies. Consult with any RF engineer -- there is no magic here, just practical engineering to solve a particular set of problems.

Would you be so kind as to un-shorten this URL? URL shorteners poison The Web. :(

done - thanks!
