Apparatus and method for improved wireless communication reliability and performance in process control systems

摘要

An apparatus includes a transceiver configured to transmit wireless signals to and receive wireless signals from wireless nodes associated with an industrial process. The apparatus also includes a controller configured to initiate transmission of the wireless signals and to process data contained in the received wireless signals. The transceiver includes a diversity receiver configured to process the wireless signals from the wireless nodes. The transceiver may be further configured to perform beam-shaping in order to transmit a directional beam to at least one of the wireless nodes. Also, the controller may be configured to perform spatial routing by identifying a target of a wireless transmission and to initiate transmission of the directional beam towards a known or estimated location associated with the identified target.
