What is Amazon Sidewalk?

Amazon Sidewalk is a shared wireless network that uses Amazon Sidewalk Bridges, such as compatible Amazon Echo and Ring devices, to enable communication among devices communicating on the network. Amazon Sidewalk enables reliable, low-bandwidth, and long-range connectivity at home and beyond. It connects IoT devices and applications such as outdoor lights, motion sensors, and location-based devices. It uses Bluetooth Low Energy for short-distance communication and CSS and FSK radio protocols at 900 MHz frequencies to cover longer distances.

How Does Amazon Sidewalk Work?

Amazon Sidewalk is a low-bandwidth wireless network comprised of nearby Bridge devices. Amazon Sidewalk Bridge device owners can opt-in to share a small portion of their internet bandwidth to provide wireless connectivity services to compatible devices within the range of Amazon Sidewalk. Each participating Bridge device expands the range of the network.

Amazon Sidewalk Architecture

Amazon Sidewalk is built on an architecture comprising of a radio, network, and application layers. It supports 3 different RF protocols. The Amazon Sidewalk application layer then sits on top of both the network layer and Bluetooth LE stack providing an easy way for customers to use the available protocols. All Amazon Sidewalk devices must connect to the cloud using AWS loT Core for Amazon Sidewalk.

Amazon Sidewalk Bridge Devices

Unlike many loT technologies based on a single gateway, Amazon Sidewalk is based on a single distributed network architecture of nearby Bridges. Having more Amazon Sidewalk Bridges in an area can increase the effectiveness of the network. When the infrastructure expands, the Bridges form a distributed network allowing devices to connect and send data to any Bridge in range instead of being limited to one specific Bridge. Amazon Sidewalk Bridges will pick up the message from the compatible device and route it through the AWS cloud to the user with multiple layers of security.

Amazon Sidewalk - Connecting Wireless IoT Devices at Homes and Beyond

In addition to extending connectivity beyond the front door, Amazon Sidewalk can be used by loT applications to deliver end-users convenience while opening up new possibilities for device manufacturers.
