Amazon has revealed further details about Sidewalk, its “neighbourhood network”, first announced in 2019 and scheduled for launch later this year.The new product uses Bluetooth Low Energy (BLE), the 900 MHz spectrum, and other frequencies to allow devices to continue working when they are beyond the range of home Wi-Fi, including outdoors. The connectivity, delivered via shared, pooled bandwidth, is provided at no extra charge to customers.Sidewalk could also help people find escaped pets or lost valuables and manage smart security and lighting, as well as supporting diagnostics for appliances and tools.In addition, experts say smart city projects could both leverage and learn from Amazon Sidewalk.
