AB  - Wireless sensors and actuators offer benefits to largeindustrial  control  systems.  The  absence  of  wires  for  commu-nication  reduces  the  deployment  cost,  maintenance  effort,  andprovides  greater  flexibility  for  sensor  and  actuator  location  andsystem  architecture.  These  benefits  come  at  a  cost  of  a  highprobability  of  communication  delay  or  message  loss  due  to  theunreliability  of  radio-based  communication.  This  unreliabilityposes  a  challenge  to  contemporary  control  systems  that  aredesigned with the assumption of instantaneous and reliable com-munication.  Wireless  sensors  and  actuators  create  a  paradigmshift in engineering energy-efficient control schemes coupled withrobust communication schemes that can maintain system stabilityin the face of unreliable communication. This paper investigatesthe  feasibility  of  using  the  low-power  wide-area  communicationprotocol   LoRaWAN   with   an   event-triggered   control   schemethrough modelling in Matlab. We show that LoRaWAN is capableof meeting the maximum delay and message loss requirements ofan  event-triggered  controller  for  certain  classes  of  applications.We  also  expose  the  limitation  in  the  use  of  LoRaWAN  whenmessage  size  or  communication  range  requirements  increase  orthe underlying physical system is exposed to significant externaldisturbances.
