Last fall, Amazon announced Sidewalk, a way to keep low-power, low-bandwidth IoT devices connected even when they’re far from your WiFi router. Today, Amazon revealed a few new details, including the addition of Echo and Tile devices. The company plans to launch Sidewalk “later this year.”

Sidewalk will use the 900 MHz spectrum to extend WiFi networks so that they can reach connected devices that would typically be out of range, for instance, smart lights at the end of your driveway. WiFi will pass through Sidewalk Bridge devices, like Ring Floodlight Cams, Ring Spotlight Cams and Echo products. Sidewalk-enabled devices (including Tile trackers) will be able to connect to nearby networks through those Bridge devices, and neighborhoods can join forces to create a low-power, community-wide network powered by their WiFi routers and channeled through Bridge devices.
