1. Introduction
WF-R11C-UWD1 module design is based on Realtek RTL8811CU solution, The RTL8811CU is a highly
integrated single chip which has built in a 1x1 single-band wireless LAN radio. The Module is a highly
integrated MAC/BBP and 2.4/5GHz PA/LNA single chip which supports a 433.3Mbps PHY rate. The
Module is designed to support standard-based features in the areas of security, quality of service, and
international regulations, giving end users the greatest performance anytime and in any circumstance.
This documentation describes the engineering requirements specification.
1.1 RF module Overview
The general HW architecture for the module is shown in Figure 1. This WLAN Module design is based
on Realtek RTL8811CU. It is a highly integrated single-chip SISO(single In single Out) Wireless LAN
(WLAN) network interface controller complying with the 802.11 specification over USB interface. It
combines a MAC, a 1T1R capable baseband, and RF in a single chip. An intelligent Wi-Fi coexistence
algorithm is implemented to provide the best harmonized Wi-Fi performance.
