Most connections will be Wi-Fi or local. Very few require 5G high speeds or latency. Consumer IoT will come, but industrial is now leading the way. Those observations are from Linley Gwennap, one of the world's leading chip analysts. I listen closely to the chip guys, who often see trends several years ahead.
Wi-Fi is close to ubiquitous in every middle class home, so why pay a phone company to connect you in home or office? The vast majority of IoT apps are low speed and latency tolerant. Your air conditioner or washing machine doesn't need to communicate at megabits/second, much less gigabits. Adding Wi-Fi is just a couple of bucks and getting cheaper. 802.11ac is delivering a routine 500 megabits.
Promised: 10 year battery life;, very low power; 15 km reach; 50-meter ground penetration; not stopped by seven walls; doesn't need a spectrum allocation. It's also darned cheap. The performance is a dismal 0.3 kbps to 50 kbps but it still sounds impossible.
Little chipmaker Semtech seemed to be tilting at windmills until Bouygues turned on Grenoble and Paris. Bouygues plans 20 cities in France by the end of this year. France Telecom responded they will cover "the entire nation" by the end of next year. Now Tata, a $100B conglomerate, announced they will serve 400M people in India's cities. Swisscom and KPN have announcements.
Lots to report but only briefs for now. Sorry. Dave
Tata doing India, France Telecom and Bouygues France.
Uses Hedy Lamarr's invention, Spread Spectrum.
Promises lowest power, lomgest reach and lowest cost.
Six others make same claim.

Live in San Francisco: 30 SIGFOX Nodes
Promises 10 more U.S. cities soon; 4000 nodes including W. Europe within a year. San Francisco offered SIGFOX access to city buildings including libraries. It already "covers" France, neighboring countries and London. Based in Labège, France. In Europe, they use the narrow 868MHz band and in the U.S. 902 MHz. Like several competitors, it claims long reach and low cost.
