Silicon Labs unveils dual-band FG28 SoC supporting Amazon Sidewalk, Wi-SUN, and other long-range wireless protocols

Silicon Labs has introduced its latest innovation, the dual-band FG28 SoC (System on Chip). This advanced SoC offers support for long-range networks and protocols such as Amazon Sidewalk, Wi-SUN, and various proprietary protocols. With this flexible connectivity solution, Silicon Labs continues to build on its wireless connectivity offerings and equip developers to create next-gen Internet of Things (IoT) applications.

The FG28 SoC brings the power of the Amazon Sidewalk to connected devices. Amazon Sidewalk uses a shared wireless network that leverages Sidewalk Bridges, including compatible Amazon Echo and Ring devices, to facilitate communication among devices within the network. With wireless connectivity, IoT devices deployed in outdoor applications using motion sensors and location-based devices can integrate into the network. Amazon Sidewalk achieves this by using Bluetooth Low Energy for short-range communication and utilizing CSS and FSK radio protocols for long distances.

“By including Bluetooth, it gives users an easy way to provision and deploy new devices onto the network, while the sub-GHz band is designed to support device communications over one mile, allowing for new edge applications in areas like smart agriculture, smart cities, and neighborhood networks like Amazon Sidewalk,” says Daniel Cooley, CTO of Silicon Labs.

FG28 SoC allows for the integration of multiple protocols into a single design. As connectivity and computing power continue to extend to the edge, emerging applications require solutions that can cater to diverse connectivity requirements. FG28, with its sub-GHz connectivity leveraging networks like Wi-SUN, is ideal for battery-operated end nodes in smart cities.

Security is a growing concern in the IoT ecosystem, and Silicon Labs addresses this challenge with its Secure Vault technology. Secure Vault is a suite of advanced security features designed to mitigate IoT threats effectively. It is claimed to significantly reduce the risk of security breaches, intellectual property compromise, and revenue loss from counterfeiting.
