An adaptive channel diversity (ACD) ISA100.11-based method in wireless systems for industrial monitoring has been developed. The reliability performance (packet error rate vs. throughput) is calculated using measured data. It improves communication reliability by dynamically selecting higher quality frequency channels. Static analysis 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 and that the effect is evident when the radio link quality is measured during periods of interference noise. The ACD method can thus be used to measure communication link quality in wireless radio environments and thus help reduce interference from other wireless systems.
