LoRa (Long Range) networks are optimized for low power, low-cost connections for the Internet of Things. The initial deployments were regional for applications like meter reading and pipe management. It works, but the takeup has been far less than hoped.
Adtran sees a better market serving individual buildings or campuses. It has just introduced the very small 7310-08 LoRaWAN IoT Gateway that can be mounted on a wall and powered over Ethernet. It can be managed by an iPhone using Bluetooth.
It should be able to transmit throughout most of a building, where 5G might need several units. The price hasn't been released, but it should be a heckuva lot less than 5G.
(Irrelevancy. The name comes from Harald Bluetooth, a king of Denmark in the 10th century. Some engineers have a sense of humor.)
LoRaWan uses 900 MHz spectrum, free to use in many countries. The speed is only 0.3 kbps to 50 kbps, enough for even battery-operated devices to occasionally phone home. The protocol is optimized for, yes, long range. At low baud rates, it can be highly reliable.
There's a 60-minute video Everything you need to know about LoRaWAN if you want an introduction to the technology.
