Amazon Sidewalk creates a low-bandwidth network with the help of Sidewalk Bridge devices including select Echo and Ring devices. These Bridge devices share a small portion of your internet bandwidth which is pooled together to provide these services to you and your neighbors. And when more neighbors participate, the network becomes even stronger.
The service is designed to help simplify new device setup, extend the low-bandwidth working range of devices to help find pets or valuables with Tile trackers, and help devices stay online even if they are outside the range of their home wifi. Amazon says that in the future, Sidewalk will support a range of experiences from using Sidewalk-enabled devices, such as smart security and lighting and diagnostics for appliances and tools.
Currently, data used by Sidewalk is capped to 500MB per month per account. You can learn more about how it works here.
