IV.2 Operations

IV.2.1 Protocol Support

The WFS802b uses the widely accepted 802.11b 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 WFS802b also supports User Datagram Protocol (UDP) for typical datagram applications in

which devices interact with other devices without maintaining a point-to-point connection.
