These Wi-Fi-enabled devices can be deployed or activated in disaster areas to quickly re-establish connectivity and improve communication between first responders and civilians in need.<br>><br>> In OWL, a central portal connects to solar- and battery-powered, water-resistant DuckLinks. These create a Local Area Network (LAN). In turn, these power up a Wi-Fi captive portal using low-frequency Long-range Radio (LoRa) for Internet connectivity. LoRA has a greater range, about 10km, than cellular networks.<br>> [...]<br>> You don't actually need a DuckLink device. The open-source OWL firmware can quickly turn a cheap wireless device into a DuckLink using the -- I swear I'm not making this up -- ClusterDuck Protocol. This is a mesh network node, which can hook up to any other near-by Ducks.<br>><br>> OWL is more than just hardware and firmware. It's also a cloud-based analytic program.
