Abstract (in Japanese) (See Japanese page) 
(in English) An adaptive frequency channel diversity has been developed in wireless systems for industrial monitoring based on ISA100.11a standard. The reliability performance (packet error rate vs. throughput) is calculated using measured data. It improves communication reliability by dynamically selecting higher quality frequency channels. The analytical evaluation using a 30-device system with a star topology showed that using this method can reduce system latency by about 65% under wireless LAN conditions. This adaptive diversity method can thus be used to measure communication link quality in wireless radio environments and thus help reduce interference from other wireless systems.
