Amazon Sidewalk, a new wireless mesh service, will share a small portion of users’ internet bandwidth with nearby neighbors who have no connectivity and vice versa.

The service calls into question the extent of the invasion of users’ personal privacy and security.

By default, Amazon devices such as Alexa, Echo, Ring, security cams, outdoor lights, motion sensors, and Tile trackers are all integrated into the system using Web host, retailer and entertainment giant.

While Sidewalk is currently only available in the United States, millions of people are enrolled in the program, regardless of whether they know about it or not, as few people bother to change the default settings.
