7 Summary

This application report discusses how having multiple gateways benefits the robustness, range and node balancing capabilities of a network that relies on the TI 15.4-Stack. The application report introduced the concept of a central gateway which provides synchronization services between local gateways that act as PAN coordinators for local TI 15.4 networks and communicate directly with sensor devices. Furthermore, the application report describes the steps to implement PAN coordinator switching which is a requirement for the enabling of multiple gateway support. Lastly, the application report discusses two use-case scenarios for PAN coordinator switching and presents some example code to demonstrate how multiple gateway support does not require modifications to the TI 15.4-Stack.
