EFR32 Series 1 Long Range Configuration Reference#

NOTE: This section replaces UG460: EFR32 Series 1 Long Range Configuration Reference. Not recommended for new designs. For new designs, see EFR32 Series 2 Long Range Configuration Reference.

To help customers achieve the crucial design element of maximum effective range, Silicon Labs has developed a Long Range radio profile for the EFR32 Series 1 family of Wireless MCU devices. This guide introduces the profile, describes its development, and examines underlying details that enable it to realize extended range. It also includes an exercise to build a Range Test example using Simplicity Studio 5 and to explore the Long Range profile, so that you can quickly begin implementation in your next project.

This guide is designed for developers who would like to test long range performance on EFR32 Series 1 devices using Simplicity Studio 5 and Silicon Labs development hardware. It provides instructions to get started using the example applications provided with the Gecko SDK Suite (GSDK) v3.
