Product Description

1. Introduction
 

Fn-Link Technology would like to announce a low-cost and low-power consumption module which has all of the Wi-Fi functionalities.
It is a highly-integrated IEEE 802.11 a/b/g/n/ac MAC/Baseband/RF WLAN single chip.
For Wireless LAN(WLAN)operation. The integrated module provides SDIO interface for Wi-Fi .
The module provides simple legacy and 20MHz/40MHz/80MHz co-existence mechanisms to ensure backward and network compatibility.

The wireless module complies with IEEE 802.11 a/b/g/n/ac standard and it can achieve up to a speed of 433.3Mbps with single stream
in 802.11ac draft to connect to the wireless LAN.
The integrated module provides SDIO interface for Wi-Fi, UART / PCM interface for Bluetooth.

This compact module is a total solution for a combination of Wi-Fi + BT technologies.

The module is specifically developed for Smart phones and Portable devices.
