If I'm reading things correctly, the per fire alarm power rating is 120V 
at 80 mA or 9.6 W. The per power FiWi transceiver estimate is 2 Watts 
per spatial stream at 160MhZ and 1 Watt for the fiber. Looks like a 
retrofit of a fire alarm system would have sufficient power for FiWi 
radio heads. Then it's punching a few holes, run fiber, splice, patch & 
paint which is very straightforward work for the trades. Rich people as 
early adopters could show off their infinitely capable in-home network. 
Installers could do a two-for deal, buy one and I'll install another in 
a less fortunate community. 

Sharktank passed on the Ring deal - imagine having a real, life-support 
capable, & future-proof network vs just a silly doorbell w/camera.
