3、s information. Sidewalks design also ensures that owners of Sidewalk gateways do not have access to the contents of the packet from endpoints (they do not own) that use their bandwidth. Similarly, endpoint owners do not have access to gateway information. The Sidewalk Network Server continuously “ro

Data Minimization Sidewalk minimizes the use of metadata wherever possible. Sidewalk uses the metadata needed to route packets from (to) the en

For example, when a packet is sent from the endpoint to the Application Server, the Sidewalk Network Server needs to know: Endpoint Sidewalk-ID to authenticate the Sidewalk-compatible device Endpoint Payload Size to en
