Design of WLAN based system for fast protocol factory automation system

This paper proposes a design of wireless communication system, particularly physical layer system (PHY) for Factory Automation (FA) system based on Wireless Local Area Network (WLAN) communication system. The designed PHY system is developed based on a fast and deterministic communication featuring a synchronous multi user round robin transmission protocol. Low overhead Packet Division Multiple Access (PDMA) scheme is utilized for Multi-user Downlink transmission, while the Frequency Division Multiple Access (FDMA) is employed for the uplink transmission. For efficient PHY implementation, several approaches on architectural aspects are also introduced. Implementation results show that the optimized design of transmitter and receiver have efficient logic resource while maintain required processing speed and error performance.
