Английская Википедия:Amazon Sidewalk
Шаблон:Short description Шаблон:Infobox networking protocol Amazon Sidewalk is a low-bandwidth long-range wireless communication protocol developed by Amazon.[1] It uses Bluetooth Low Energy (BLE) for short distance communication,[2] and 900 MHz LoRa and other frequencies for longer distances.[3]
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 late 2017 and after Ring was acquired by Amazon in 2018,[4] 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.[1][5][3] The network is composed of existing customers' Echo smart speakers which act as the bridges between Sidewalk and the Internet.[6]
In September 2020, Amazon started seeking hardware developers to partner and develop devices for the network.[7]
In May 2021, Amazon and Tile announced plans to use Sidewalk to compete with the AirTag tracker device and associated location service from Apple.[8] CareBand starts a pilot with Amazon Sidewalk to support people living with dementia in smart neighborhoods.[9]
Amazon launched the network in the US on June 8, 2021.[10][11]
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.[12]
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.[10]
A number of prominent news publishers, including The Guardian,[13] ArsTechnica,[11] CNET,[14] PCMag,[15] Click2Houston,[16] and Bleeping Computer,[17] 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."[18] 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".
Transmission technologies:
- 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
Devices
The following devices support Amazon Sidewalk:
- Amazon Echo devices
- Ring doorbells and cameras
- CareBand wearables for people living with dementia
- Fetch, an upcoming pet collar from Tile[6]
