Amazon Sidewalk

Amazon Sidewalk allows endpoint devices to utilize the pre-existing Amazon Sidewalk network, enabling service providers and utilities to deploy monitoring networks without the operational expense, carbon footprint and overhead of deploying and managing gateways. Amazon Sidewalk makes use of existing Amazon Echo and Ring devices to create a low bandwidth network that devices can use to communicate with the AWS cloud. The Amazon Sidewalk network is built such that devices can roam onto existing Sidewalk gateways and the gateway can use its network connection to route data to cloud services. This creates a low power, best-effort community network.

Amazon Sidewalk devices inherently support a number of features that help optimize power consumption.  Sidewalk uses power-efficient wireless communication protocols such as Bluetooth Low Energy (BLE).  It also uses adaptive transmission power, which adjusts the transmit power of connected devices based on the distance between devices, reducing power consumption and extending battery life.  Devices connected to Amazon Sidewalk also enter a low-power sleep mode when not in use, which also extends battery life.
