2 Introduction
NW-111 is a 3x3 11n/b/g/a 2.4/5GHz dual-band WiFi module. It is based on
Qualcomm Atheros AR9580 chip solution. This module uses 3x3 multiple
input/multiple output (MIMO), Orthogonal Frequency Division Multiplexing
(OFDM) and Direct Sequence Spread Spectrum (DSSS) communication
techniques. AR9580 provides wireless data communications at rates of up to
450Mbps, depending on the coding techniques employed and the range of the
system.
3 Functions:
3.1 IEEE standard supports 802.11n/g/b/a
3.2 Support 20/40MHz bandwidth with 64QAM modulation
3.3 Spatial multiplexing up to 450Mbps data rate by 3T3R.
3.4 Doesn’t support DFS frequencies per different country’s regulations.
3.5 RoHS compliant
