Amazon's New Idea ... Amazon Sidewalk

Episode 1750
Wanting to offer a neighborhood-based wifi network, Amazon has announced Amazon Sidewalk, which uses Bluetooth low energy (BLE) radios to connect everyone from house to house. You can get motion alerts from your security cameras, track your pets if they should run away, and even notifications when the mailman leaves you mail. As long as one device sees the other, it can pass along connectivity with a promised small amount of bandwidth.
