Amazon is now starting to rolling out its Amazon Sidewalk local networking system to customers in the U.S.

With that in mind, here are some of the important points that users should know about Amazon Sidewalk.

A Sidewalk Bridge connects to your Wi-Fi network, and essentially extends the connectivity range beyond what your router can output.

The bandwidth in a Sidewalk network is open for not just your own devices, but your neighbors', too.

Most Amazon device owners already have a Sidewalk Bridge in their homes.

If you happen to drop a Tile device while walking around the neighborhood, it could still be within range of the local Sidewalk network — and it'll be able to connect to the appropriate servers using a neighbor's Sidewalk bandwidth.

The bandwidth available on a Sidewalk network is pretty small — Amazon says the maximum bandwidth is just 80Kbps, with a maximum cap at 500MB.

Although Amazon says it will encrypt all traffic sent through a Sidewalk network, users won't know who is on a specific network or how much traffic their neighbor might be sending over it.

All in all, users will only be able to exercise marginal control over their local Sidewalk networks.

There isn't currently a way for users to figure out which Sidewalk Bridge their compatible devices are connected to.

Once Amazon actually enables Sidewalk, users will see an information splash screen that explains what it is and what it does.

If users do disable Sidewalk, their devices won't be able to connect to their local neighborhood networks.

Basically a glorified mesh network (across households) for Amazon devices (Echo, Ring).

Amazon Sidewalk is all about providing a very low cost, low bandwidth, highly distributed, mesh network (using BTLE and 900 MHz) for locating and discovering identification tags and exchanging a few bits of data with simple sensors.
