IoT and IIoT applications often contend with multiple wireless protocols. Typically, a gateway deals with this aspect because of the chips needed to address more than one protocol. The SYN4381 Triple Combo wireless system-on-chip from Synaptics supports 600-Mb/s,Wi-Fi 6 IEEE 802.11ax-compliant WLAN, Bluetooth 5.2, and Zigbee.

In this video, Brandon Bae highlights the operation and advantages of the SYN4381. The chip handles 802.11a/b/g/n/ac legacy Wi-Fi and features four external PAs and LNAs. There's also a multipoint external coexistence interface for LTE and GPS, Bluetooth 5.2 support for Bluetooth Low Energy (BLE) isochronous channels, LE audio, A2DP support, host encryption key size control, and HADM for accurate distance measurement. The ultra-low-power mesh networking Thread/Zigbee support uses the IEEE 802.15.4-based standard to provide cross-platform interoperability.
