4.2. WIFI RADIO AND BASEBAND
The ESP32-S3 Wi-Fi radio and baseband support the following features:
•
802.11b/g/n
• 802.11n MCS0-7 that supports 20 MHz and 40 MHz bandwidth
• 802.11n MCS32
• 802.11n 0.4 μs guard-interval
• Data rate up to 150 Mbps
• RX STBC (single spatial stream)
• Adjustable transmitting power
• Antenna diversity:
ESP32-S3 supports antenna diversity with an external RF switch. This switch is
controlled by one or more
GPIOs, and used to select the best antenna to minimize the effects of channel
imperfections.
