5G technology and its potential to ‘revolutionize’ the industry are of interest to grain industry and researchers. To meet this ‘step change’, it is necessary to understand the compatibility of grain industrial chains with 5G and how 5G technology might change the industry. We conducted a discourse analysis of advantages of 5G in grain industry. Two main discourse were identified: (1) 5G as a technology that will significantly improve the efficiency of the grain industry systems, and similarly (2) 5G as a way for every participant to benefit. It provides quality service. We relate these findings and the literature on adoption of information technology in grain industry and the potential of grain participants to embrace 5G technology, highlighting key questions and issues that need to be addressed in further development of 5G technology in grain industry. This is the first study of 5G in grain industry that use discourse analysis to examine the whole grain industry system and thus make better progress in the application of 5G technology.
