Introduction
The WFS802g WiFi (802.11g) serial module is the most compact, integrated solution available to add 802.11g
wireless networking to your robots with a serial interface.
To enable access to a local network or the internet, the WFS802g integrates a fully developed TCP/IP network
stack and OS. The WFS802g also includes an embedded web server that can be used to remotely configure,
monitor, or troubleshoot the attached device.
The WFS802g is the most compact, integrated solution available to add 802.11g wireless networking to any
device with a serial interface. Using our highly integrated hardware and software platform, you will add to your
bottom line by significantly reducing product development time, risk, and cost.

Protocol Support
The WFS802g uses the widely accepted 802.11g protocol to connect to a wireless access point or an ad hoc
network. It uses the Transmission Control Protocol (TCP) to ensure that no data is lost or duplicated and
everything sent to the connection arrives correctly at the target.
The WFS802g also supports User Datagram Protocol (UDP) for typical datagram applications in which devices
interact with other devices without maintaining a point-to-point connection.
