WLAN FUNCTIONAL DESCRIPTION
Overview
The M2US50NBT/M2SD50NBT WLAN block is based on the Laird SSD50NBT SIP (System in Package). It is
optimized for low-power embedded applications and is configured to operate in dual-band, two-stream (2x2
MIMO) mode. Its functionality includes:
Improved throughput on the link due to frame aggregation, RIFS (reduced inter-frame spacing), and half-
guard intervals.
Support for STBC (space-time block coding) and LDPC (Low Density Parity Check) codes.
Improved 11n performance due to features such as 11n frame aggregation (A-MPDU and A-MSDU) and
low-overhead host-assisted buffering (RX A-MSDU and RX A-MPDU). These techniques can improve
performance and efficiency of applications involving large bulk data transfers such as file transfers or high-
resolution video streaming.
