Amazon Sidewalk Devices

Sidewalk devices are the devices used to construct Amazon Sidewalk network. Amazon Sidewalk is a shared network designed and operated by Amazon to help connecting your low powered smart devices to the network, both at home and beyond the front door, even if they are outside the range of your home WiFi network.

The Sidewalk network makes use of LoRa, Bluetooth Low Energy (BLE) and also your home broadband network connectivity via different kind of network devices in your neighborhood to run the network. This means your outdoor smart device could connect to your neighbor Sidewalk gateway if it has difficulty to connect to your Sidewalk gateway or home router.

These are key components of the Sidewalk network and I will explain in more details: Sidewalk Gateway, Sidewalk Endpoint, Sidewalk Network Server, Application Servers, and Packets.
Amazon Sidewalk network components
Sidewalk Gateway (also knowns as Sidewalk Gateway or Bridge): This is a type of device you can buy from Amazon. This is key network component that acts as entry point for connecting your low powered smart devices to Sidewalk network and you need to have at least one such device. It uses 900 MHz (LoRa and/or frequency-shift keying (FSK), and/or Bluetooth Low Energy (BLE) to provide connection to the Sidewalk network. Very often a Sidewalk gateway is also a Sidewalk endpoint. An example of Sidewalk gateway is Ring Sportlight cam that works as sportlight cam too.

A comprehensive list of Sidewalk devices includes: Ring Floodlight Cam (2019), Ring Spotlight Cam Wired (2019), Ring Spotlight Cam Mount (2019), Echo (2nd Gen), Echo (3rd Gen), Echo (4th Gen), Echo Dot (2nd Gen), Echo Dot (3rd Gen), Echo Dot (4th Gen), Echo Dot (2nd Gen) for Kids, Echo Dot (3rd Gen) for Kids, Echo Dot (4th Gen) for Kids, Echo Dot with Clock (3rd Gen), Echo Dot with Clock (4th Gen), Echo Plus (1st Gen), Echo Plus (2nd Gen), Echo Show (1st Gen), Echo Show (2nd Gen), Echo Show 5, Echo Show 8, Echo Show 10, Echo Spot, Echo Studio. For more information, check out this Sidewalk FAQ page to find out more.

Sidewalk Endpoint (also known as Sidewalk-Enabled devices): This is a type of device you can buy from Amazon. Sidewalk endpoint is low-power smart products such as leak sensors, door locks, lights, or devices that you can connect to Sidewalk network via Sidewalk gateway. Sidewalk endpoints can be built and maintained by Amazon or third party (3P) developers.

Sidewalk Network Server (or SNS): This device is operated by Amazon. SNS is the backbone of the Sidewalk network. It is responsible for verifying that the incoming packets are coming from authorized Sidewalk devices, routing packets to the desired destination (an application server, endpoint or GW device), and keeping the network time synchronized.

Application Servers: This device is operated by Amazon. Essentially application server is the server on Sidewalk backbone that interacts with Sidewalk endpoints for it to function well and implement the business logic for the user experience.

Packets (also known as Messages): The packets are used to exchange information between different devices (Sidewalk gateway, end devices, SNS, etc.). Similar to a letter in the mail, the letter inside the envelope (or packet) contains information needed to perform a service (i.e. the command, “Turn on Light”). Like the post office, the SNS reads the routing information on the outside of the envelope to direct the packet to the correct endpoint and application server.
