But 5G is not meant for in house consumption. It is meant for crowded spaces like train stations, supermarkets to offload other bands. Then you get micro cells installed indoors inside of supermarkets. (what I mean by supermarket means mall and all those kind of shopping centers) It is meant also for all kinds of smart sensors in area, but not like home sensors but utilities. We have that with LoRa, but it is really small data amounts, where 5G would be used for sensors that need more data, like smart traffic lights? Then you won't have to connect your old traffic lights to some cable network and they would get good connection capabilities. Right now 4G is not used everywhere, in less dense areas you only get 3G. Of course providers will install base stations for 5G in places where it is economically possible. Places that have 3G now are not getting 5G anytime soon. It is also understandable that 900MHz is better for longer range than 1800MHz.

5G below 6GHz really requires dynamic spectrum sharing with 4G. Once that is standardized, carriers can gradually switch out 4G for 5G with modest but real benefits. I was part of a group that installed some radio gear on the roof of the local mall and I can say that the building manager of the mall was a tough customer. It really helped that he liked our (union) electrician and was certain we wouldn't contribute any leaks to the roof. Carriers used to use the IBEW and CWA and had some standards for the quality of work done. Today carriers tend to use non-union contractors -- some of those people are excellent to OK but some are real idiots that any property owner would want to keep far away. So far as serious IoT goes I think the coverage problems will still dog IoT. With fiber you can get 100% coverage -- it costs money, but there is no site that can't be served. Will cell phones carriers will tell you they cover 98% of POPs, when you investigate it might be more like they cover 89% of POPs. With wireless systems you make a rather large capital investment that rapidly erodes in value to get to that 89% coverage but then the cost explodes from there.
