Silicon Labs Connect is an IEEE 802.15.4 MAC-based wireless networking stack for a variety of proprietary applications optimized for low power devices. This full-featured, easily customizable networking stack is designed for compliance with regulatory specifications across worldwide geographic regions and supports both Sub-GHz and 2.4 GHz frequency bands.
The stack supports many combinations of radio modulation, frequency, and data rates allowing devices to be configured as end nodes, coordinators, and range extenders. It includes all wireless MAC (Medium Access Control) layer functions such as scanning, joining, setting up a point-to-point, or extended star network, as well as managing device types such as sleepy end devices, routers, and coordinators. With all this functionality already implemented in the stack, you can focus on your end application development and not worry about the lower-level radio and network details.
