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.
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.
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.
Amazon Sidewalk amalgamates multiple physical-layer wireless networking protocols and presents them into a single application layer they call "Sidewalk Application Layer".
- Bluetooth Low Energy for short distances and battery efficiency
- LoRa for long-range low-power communication
- Frequency-shift keying at 900 MHz, intended for interacting with legacy home appliances like garage door openers
