'Researchers at Brigham Young University have created a new RF protocol that runs on top of existing consumer Wi-Fi at significantly greater range. But before you get too excited, the protocol's bandwidth is extremely low—so much so that it makes LoRa look like an OC-24. The protocol, called ONPC—short for On-Off Noise Power Communication—currently only specifies a single bit per second. Although ONPC only conveys one bit per second of data, its range is 60m or more beyond Wi-Fi—and it runs in software alone, on unmodified Wi-Fi hardware. An ONPC device can connect to standard Wi-Fi when range permits, fall back to ONPC mode if the connection drops, and then re-connect to the Wi-Fi when it becomes available again.' -- source: https://arstechnica.com/gadgets/2019/11/where-the-wi-fi-sucks-is-where-a-new...
