1. Introduction

GWF-3M05 is a WLAN module supporting IEEE 802.11 b/g/n standards with 6-pin connector
supporting USB 2.0 interface. This is a low cost compact WLAN module designed in products
with embedded system for the wireless connectivity. This Module is designed to operate in

2.4GHz ISM frequency band, it applies a highly integrated MAC/BBP and RF single chip RT3070
with 150Mbps PHY rate supporting. It fully complies with IEEE802.11n draft 3.0 and
IEEE802.11b/g feature.
