Amazon Sidewalk Explained

Amazon Sidewalk is a new technology that allows you to control your smart devices with a single app. It's a network that lets your devices communicate with each other.

Amazon Sidewalk is built on top of the LoRaWAN protocol, which is a low-power, low-bandwidth wireless communication standard. This means it's designed to be energy-efficient and can work with devices that have limited power.

The network is designed to be secure, with end-to-end encryption and access controls that let you decide who can join and what they can do. Amazon Sidewalk also has a feature called "mesh networking", which lets your devices act as repeaters to extend the network's reach.

Amazon Sidewalk is free to join and requires no additional cost beyond the cost of your existing Amazon devices.

Amazon Sidewalk is a low-bandwidth network developed by Amazon to allow low-power devices to communicate over longer distances than Bluetooth or Wi-Fi would typically allow for.

The idea behind Sidewalk is to provide a free community network that will open up the possibility for the development of new types of devices. This network has many business and personal applications.

One of the main benefits of Sidewalk is that it will enable the creation of new types of devices for things like tracking packages.

Amazon Sidewalk's architecture is built around a few key technologies, including LoRa, which is an ultra-low-power and extremely long-range wireless technology. This tech is perfect for IoT solutions, and it's already widely used in many industries.

LoRa-enabled devices with Amazon Sidewalk have a long range and ultra-low power compared to other wireless technologies, making them ideal for devices that need to conserve battery life.

Amazon Sidewalk amalgamates multiple physical-layer wireless networking protocols, including Bluetooth Low Energy, LoRa, and Frequency-shift keying at 900 MHz. This combination allows for efficient communication between devices.

Here's a breakdown of the transmission technologies used in Amazon Sidewalk:

The architecture also includes a single application layer, which they call the "Sidewalk Application Layer". This layer presents the multiple physical-layer wireless networking protocols in a unified way, making it easier to develop applications that use Amazon Sidewalk.

Amazon Sidewalk's community network is a game-changer for IoT devices. It's a secure, free-to-connect network that uses participating Amazon Sidewalk Bridges, such as compatible Amazon Echo and Ring devices, to provide cloud connectivity.

The network is highly encrypted and leverages small portions of internet bandwidth from millions of these Sidewalk Bridges to provide widespread wireless connectivity to the community. This means you can enjoy seamless connectivity with your IoT devices without worrying about security.

Amazon Sidewalk already covers more than 90% of the U.S. population, and this is just the beginning. With Amazon Sidewalk open for developers and innovators, the possibilities are endless.

Here are some key benefits of Amazon Sidewalk's community network:

Amazon Echo devices come with Sidewalk enabled by default, and it's not immediately clear to the owner.

A number of prominent news publishers have expressed concern about the opt-out nature of the network.

The official app allows you to disable Amazon Sidewalk if you're not comfortable with the feature.

Amazon claims that the maximum bandwidth of a Sidewalk Bridge to the Sidwalk server is 80 Kbps, which they say is a small fraction of the bandwidth used to stream a typical high definition video.

However, this comparison is misleading for ADSL connections with upstream bandwidth more limited than downstream bandwidth.

Amazon Sidewalk's community network is a secure, free-to-connect network that uses participating devices like Echo and Ring to provide cloud connectivity for IoT devices. It leverages small portions of internet bandwidth from millions of these devices to provide widespread wireless connectivity.

The network uses LoRa technology, which operates at a long range, enabling devices to connect at a broader scale and longer distance than most other wireless technologies. This provides developers and innovators with an amazing opportunity to create the next generation of sidewalk-compatible wireless devices and use cases.

There are two possible network modes in Amazon Sidewalk: WAN and PAN. WAN mode restricts endpoint-to-endpoint communication, but allows all three technologies – SubG-FSK, SubG-CSS, and BLE – to be used by endpoints.

In WAN mode, there are restrictions on how many messages endpoints can transmit on the WAN. Each endpoint has a unique device key that changes periodically, and the cloud bears the responsibility of verifying the authenticity and integrity of incoming messages from the endpoint.

PAN mode, on the other hand, allows users to set their own data usage limits and routing prioritization. It uses BLE for communication between endpoints and gateways, and restricts the number of messages over BLE to 600 per minute.

Here's a comparison of WAN and PAN modes:

Amazon Sidewalk is now open for developers and innovators, and the possibilities are endless. Innovative developers will create new devices and services that benefit the community, such as helping you locate lost items and extending the range of Amazon Sidewalk compatible smart devices.

As an Amazon Sidewalk developer, you'll have the opportunity to create low power, long-range IoT devices that can enhance the functionality and efficiency of IoT solutions. This is made possible by leveraging LoRa and Amazon Sidewalk.

Developers can get started quickly with LoRa on Nordic and Silicon Labs developer kits, which have been created to help you get up and running. These kits will walk you through the prerequisites and setting up LoRa, giving you a solid foundation to build on.

The user experience is just as important, and Amazon Sidewalk offers a mobile app or web interface that allows users to interact with endpoints and configure settings. This interface is what brings everything together, making it easy for users to initiate actions and get responses from other devices.

Amazon Sidewalk Developer Kits are available for developers to create low power, long-range IoT devices.

These kits are designed to help developers get started with LoRa technology on Nordic and Silicon Labs developer kits. You can find a guide to quickly get up and running with LoRa on these kits.

The Silicon Labs Pro Kit For Amazon Sidewalk is one of the available developer kits.

To use the developer kits, you'll need to follow the prerequisites for both kits, which are outlined in the guide. This will help you set up and enable LoRa on your device.

Here are some key features of the developer kits:

The user interface is a crucial aspect of any device or system, and Amazon Sidewalk is no exception. The end-user interface for Amazon Sidewalk could be a mobile app or web interface, allowing users to interact with the endpoints.

This interface enables users to configure settings, initiate actions or commands, and get responses from other Sidewalk devices or bridges, such as the Echo and Ring devices.

Amazon Sidewalk utilizes a few wireless protocols to support both short and long range communication on the network. These protocols include Bluetooth Low Energy (BLE), SubG-FSK (HDR), and LoRa – also referred to as SubG-CSS (LDR).

BLE is used for short-distance communication, providing a high data rate but a shorter range. SubG-FSK and LoRa are used for medium and long range communication, respectively.

Here's a breakdown of the wireless protocols used by Amazon Sidewalk:

Sidewalk Bridges, such as compatible Amazon Echo and Ring devices, support all three technologies, but automatic switching between the three modulations is not currently supported at the Amazon Sidewalk endpoints. This means that the network will use one protocol for communication, depending on the specific use case.

BLE provides power-efficient, low-latency communication within the network, and it's the most efficient technology of the three. However, it has a shorter range compared to the other two protocols.
