The Realtek RTL8192SE 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 RTL8192SE provides a complete solution for a high throughput performance wireless client.
The RTL8192SE 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. The RTL8192SE also supports explicit sounding packet feedback that helps senders with beamforming capability. With 2 independent RF blocks, the RTL8192SE can perform fast roaming without link interruption.
The RTL8309N is an 8-port 10/100M Ethernet switch controller that integrates memory, eight MACs, and eight physical layer transceivers for 10Base-T and 100Base-TX operation into a single chip.
The RTL8309N supports 16 VLAN groups. These can be configured as port-based VLANs and/or 802.1Q tag-based VLANs. The RTL8309N also supports VLAN learning, with four Independent VLAN Learning (IVL) filtering databases.
