3 Product Specification Document
2 Introduction
NW-121 is a 3x3 11ac/n/b/g/a 2.4/5GHz dual-band WiFi module. It is based on
Qualcomm Atheros QCA9880 chip solution. This module uses 3x3 multiple
input/multiple output (MIMO), Orthogonal Frequency Division Multiplexing
(OFDM) and Direct Sequence Spread Spectrum (DSSS) communication
techniques. QCA9880 provides wireless data communications at rates of up to
1.3Gbps, depending on the coding techniques employed and the range of the
system.
3 Functions:
3.1 IEEE standard supports 802.11ac/n/g/b/a
3.2 Support 20/40/80MHz bandwidth with 256QAM modulation
3.3 Spatial multiplexing up to 1.3Gbps data rate by 3T3R.
3.4 Doesn’t support DFS frequencies per different country’s regulations.
3.5 RoHS compliant
