Datasheet
Single-Chip 802.11 ac/a/b/g/n 2T2R WLAN Controller
with PCI-E Interface
4
Track ID: Rev. 0.1
MAC Features
 Frame aggregation for increased MAC
efficiency (A-MSDU, A-MPDU)
 Low latency immediate Block
Acknowledgement (BA)
 Long NAV for media reservation with
CF-End for NAV release
 PHY-level spoofing to enhance legacy
compatibility
 MIMO power saving mechanism
 Channel management and co-existence
 Multiple BSSID feature allows the
RTL8822CE to assume multiple MAC
identities when used as a wireless bridge
 Transmit Opportunity (TXOP) Short
Inter-Frame Space (SIFS) bursting for higher
multimedia bandwidth
