WIRELESS CONTROLLER AREA NETWORK IMPLEMENTATIONS AND APPLICATIONS: TECHNICAL DETAILS AND CASE STUDY

This paper discusses the need and applications of the wireless version of the popular controller area network (CAN) introduced and standardized by Bosch as early as 1990. There are many practical applications where CAN messages need to be transmitted over short distances and where cable connections are either impossible or unwanted. Technical details and case study of the various possibilities of the wireless interface for the wireless transfer of CAN frames are discussed in this paper. Implementations of CAN over Bluetooth, CAN over ZigBee and CAN over UWB are presented. Among the various wireless possibilities, ZigBee based on IEEE 802.15.4 is recommended for the wireless and control applications of CAN.
