The Realtek RTL8188CE and RTL8188CEAU are highly integrated single-chip WLAN controllers supporting IEEE 802.11n. Featuring a 1T1R MIMO-OFDM baseband, MAC, and RF in one chip, they deliver high-performance wireless connectivity. Supporting 20/40 MHz channels, short guard intervals, spatial spreading, and a single spatial stream, they ensure efficient data transmission. The MAC supports 802.11e/i/n, A-MPDU, A-MSDU, and advanced power-saving features like U-APSD.
