The example most people use are farms. The problem often isn’t range, it’s power consumption. The soil moisture sensor or the cow health tracker a mile away needs to run on batteries for a long time.

Unless you need high data rates, LoRa would be a better option instead of wifi. Especially if you need a new chipset anyway.

Also, on range alone, people are pushing LoRa to insane distances: https://hackaday.com/2023/09/15/new-lora-distance-record-830-miles/

Are there any microcontrollers that support this natively? I could do some neat stuff with this kinda range and solar powered stations.
