AN1503: SiWG917 PTA 3-Wire CoExistence (Wi-Fi)#

This application note provides detailed guidance on the implementation of the PTA for the SiWG917 in Wi-Fi environments. It is assumed that readers have a basic understanding of Wi-Fi coexistence principles as applied to BLE devices.

The Silicon Labs Packet Traffic Arbitration (PTA) system facilitates the coordination of 2.4 GHz RF traffic for co-located 2.4 GHz radios and Silicon Labs wireless solutions. This involves the BLE device and SiWG917, which operate on overlapping frequency channels within the 2.4 GHz band while being spatially co-located. For further information, refer to UG103.17: Wi-Fi® Co-Existence Fundamentals.
