Features

Wi-Fi

? 1T1R in 2.4 GHz band

? Operating frequency: 2412 ~ 2484 MHz

? IEEE 802.11ax-compliant

– 20 MHz-only non-AP mode

– MCS0 ~MCS9

– Uplink and downlink OFDMA, especially

suitable for simultaneous connections in

high-density environments

– Downlink MU-MIMO (multi-user, multiple

input, multiple output) to increase network

capacity

– Beamformee that improves signal quality

– Channel quality indication (CQI)

– DCM (dual carrier modulation) to improve

link robustness

– Spatial reuse to maximize parallel

transmissions

– Target wake time (TWT) that optimizes

power saving mechanisms

? Fully compatible with IEEE 802.11b/g/n protocol

– 20 MHz and 40 MHz bandwidth

– Data rate up to 150 Mbps

– Wi-Fi Multimedia (WMM)

– TX/RX A-MPDU, TX/RX A-MSDU

– Immediate Block ACK

– Fragmentation and defragmentation

– Transmit opportunity (TXOP)

– Automatic Beacon monitoring (hardware

TSF)

– Four virtual Wi-Fi interfaces

– Simultaneous support for Infrastructure

BSS in Station mode, SoftAP mode, Station

+ SoftAP mode, and promiscuous mode.

Note that when ESP32-C6 scans in Station

mode, the SoftAP channel will change

along with the Station channel

– Antenna diversity

– 802.11mc FTM
