1.2 Descriptions
The AW3155-50R module is a complete dual-band (2.4GHz and 5GHz) Wi-Fi 1×1 MU-MIMO
MAC/PHY/Radio System-on-a-Module. It provides a high level of integration with a stream IEEE 802.11ac
MAC/baseband/radio and Bluetooth 5.0 with supporting high power mode, Mesh, Direction Finding and Long
Range. In IEEE 802.11ac mode, the WLAN operation supports rates of MCS0–MCS9 (up to 256 QAM) in 20
MHz, 40MHz, and 80 MHz channels for data rates up to 433 Mbps. In addition, all the IEEE 802.11a/b/g/n
rates are supported.
The AW3155-50R module integrates several peripheral interfaces including UART (Bluetooth), SDIO
(Wi-Fi).It Supports 2 antennas configuration for Wi-Fi and Bluetooth.
