Abstract

To address the ultra-low latency and high-reliability requirements in critical applications of industrial wireless control, high performance wireless (WirelessHP) communications has demonstrated its superiority in this area. This paper steps further by investigating the pulse interference resilience of WirelessHP physical layer, and convolutional codes (CC) are adopted for short packet transmission. Through the constructed hardware platform, duration of the pulse interference and number of pulses in each transmitted packet are adjustable, based on which the packet error rate (PER) performance is tested in real factory environments. We show 100 ns duration pulse interference has a slight influence on the PER performance if only one pulse exists in the waveform of one packet, but lose this property for longer duration pulse interference. Lower-rated CC outperforms higher-rated CC on condition of the same pulse interference settings, but is more frangible to pulse interference that with the same interference rate.
