1. Introduction
Project Name: WLAN Module
Project Number: T77H479.00
This documentation describes the engineering requirements specification of WiFi module with
T77H479.00. It is a confidential document of Foxconn.
1.1 RF module Overview
The general HW architecture for this module is shown in Figure 1. This WLAN Module design is
based on MTK RT5572N. It is a highly integrated MAC/BBP and 2.4/5 GHz RF/PA/LNA single
chip which supports a 300Mbps PHY rate. It fully complies with IEEE 802.11n and IEEE
802.11a/ b/g standards, offering feature-rich wireless connectivity at a high standard, and
delivering reliable, cost-effective throughput from an extended distance. Optimized RF
architecture and base-band algorithms provide superb performance and low power
consumption. This module is designed to support standard-based features in the areas of
security, QoS and international regulations, giving end users the greatest performance anytime
and in any circumstance.
