1. Introduction
The GWF-1M01 is a WLAN module supporting IEEE 802.11b/g/n standards with 7-pin or 4-pin connector
supporting USB2.0 interface. This is a small form factor and low cost compact WLAN module designed for
the wireless connectivity. This module operates in 2.4GHz ISM frequency band, it applies a highly integrated
MAC/BBP and RF single chip RT 5372 with 300Mbp s PHY rate supporting. It fully complies wit h IEEE802.11n
draft 3.0 and IEEE802.1 1b/g feature.
