Wi-Fi and BT

SC650T module provides a shared antenna interface ANT_WIFI/BT for Wi-Fi and Bluetooth (BT)
functions. The interface impedance is 50Ω. External antennas such as PCB antenna, sucker antenna and

ceramic antenna can be connected to the module via the interface, so as to achieve Wi-Fi and BT

functions.

4.1. Wi-Fi Overview

SC650T module supports 2.4GHz and 5GHz dual-band WLAN wireless communication based on IEEE

802.11a/b/g/n/ac standard protocols. The maximum data rate is up to 433Mbps.

The features are as below:



Support Wake-on-WLAN (WoWLAN)



Support ad hoc mode



Support WAPI SMS4 hardware encryption



Support AP mode



Support Wi-Fi Direct



Support MCS 0-7 for HT20 and HT40



Support MCS 0-8 for VHT20



Support MCS 0-9 for VHT40 and VHT80
