    Amazon Sidewalk is a low-bandwidth long-range wireless communication protocol developed by Amazon. It uses Bluetooth Low Energy (BLE) for short distance communication, and 900 MHz LoRa and other frequencies for longer distances.

    History

    The idea of the Amazon Sidewalk wireless network originated from a startup called Iotera, founded by Rob Barton and Ben Wild. They launched the idea of a crowd sourced mesh network through a Kickstarter campaign in 2014. Iotera was acquired by Ring Home Security in 2018 and after Ring was acquired by Amazon, the Amazon Sidewalk project began building on top of the Iotera technology. In September, 2019, Amazon announced the Amazon Sidewalk network and a domestic pet collar called Fetch (developed together with Tile) as the first device which would use the network. The network is composed of existing customers' Echo smart speakers which act as the bridges between Sidewalk and the Internet.

    In September 2020, Amazon started seeking hardware developers to partner and develop devices for the network.

    In May 2021, Amazon and Tile announced plans to use Sidewalk to compete with the AirTag tracker device and associated location service from Apple.CareBand starts a pilot with Amazon Sidewalk to support people living with dementia in smart neighborhoods.

    Amazon launched the network in the US on June 8, 2021.

    In March 2023, Amazon opened the network up for outside developers to access, providing free test kits for developers to build Sidewalk devices. Amazon stated that more than 90% of the U.S. population was covered by the Sidewalk network.

    Reception

    Amazon Echo devices have Sidewalk enabled by default and do not inform their owner about it. The feature can be disabled via the official app.

    A number of prominent news publishers, including The Guardian,ArsTechnica,CNET,PCMag,Click2Houston, and Bleeping Computer, expressed concern with opt-out nature of the network and published guides how to disable Amazon Sidewalk.

    Amazon stated that "the maximum bandwidth of a Sidewalk Bridge to the Sidewalk server is 80Kbps, which is about 1/40th [2.5%] of the bandwidth used to stream a typical high definition video." This comparison is misleading for ADSL connections with upstream bandwidth more limited than downstream bandwidth: 80Kbps approaches 20% of the capacity of a 448Kbps uplink.

    Technology

    Amazon Sidewalk amalgamates multiple physical-layer wireless networking protocols and presents them into a single application layer they call "Sidewalk Application Layer".
