RTL8192CE-GR datasheet controller

Description

The Realtek RTL8192CE-GR is a highly integrated single-chip MIMO (Multiple In, Multiple Out) Wireless LAN (WLAN) solution for the wireless high throughput 802.11n specification. It combines a MAC, a 2T2R capable baseband, and RF in a single chip. The RTL8192CE provides a complete solution for a high throughput performance wireless client.

The RTL8192CE baseband implements Multiple Input, Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) with 2 transmit and 2 receive paths (2T2R) and is compatible with the IEEE 802.11n specification. Features include two spatial streams transmission, short guard interval (GI) of 400ns, spatial spreading, and transmission over 20MHz and 40MHz bandwidth. Moreover, RTL8192CE provides one spatial stream space-time block code (STBC) to extend the range of transmission. At the receiver, extended range and good minimum sensitivity is achieved by having receiver diversity up to 2 antennas. As the recipient, the RTL8192CE also supports explicit sounding packet feedback that helps senders with beamforming capability. With 2 independent RF blocks, the RTL8192CE can perform fast roaming without link interruption. […]
