1. Introduction
The WF-2571 is an Industrial Ethernet to Wi-Fi Bridge that creates a
connection between an 802.11b/g wireless LAN and a device with a
standard Ethernet port. The Bridge transparently conveys data between
devices with a 10/100 Ethernet interface and a wireless LAN without
drivers or complicated addressing schemes. This significantly reduces the
complexity of network connectivity and wireless system deployment and
also provides wireless LAN and Internet connectivity to industrial, scientific
and automotive applications.

1.2.1 Features Description
The WF-2571 module offers the most comprehensive configuration to
meet specific application requirements. The following list shows the
features designed to simplify installation, configuration and application.
Compatible with IEEE 802.11b/g standards
WF-2571 module complied with IEEE 802.11b/g standard from
2.4~2.5GHz, and it can be used to provide up to 11Mbps for IEEE
802.11b and 54Mbps for 2.4GHz IEEE 802.11g to connect your wireless
LAN.
Support Infrastructure and Ad-Hoc modes for wireless network
Ad-Hoc mode lets you create a wireless network quickly by allowing
wireless nodes within range (for example, the wireless devices in a room)
to communicate directly with each other without the need for a wireless
access point.
Infrastructure mode is the more common network configuration where
all wireless hosts (clients) connect to the wireless network via a WAP
(Wireless Access Point).
Support WEP, WPA and WPA2 wireless encryption
WEP and WPA are common types of security that are used to protect
wireless networks. When WEP or WPA is turned on, WF-2571 module
uses a special security key combination to allow only devices that know
this key to connect to its wireless network. This applies to laptops, smart
device, or any other wireless device.
Built-in Watchdog
Module Watchdog is a built-in hardware circuit that monitors the
operating status of the module and will reset the module if a failure occurs
in the hardware or the software.
