> 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.

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.
