The Internet of Things (IoT) is increasingly pervasive and ubiquitous in various areas. The industry is incorporating intelligence into it is processes through the Industrial Internet of Things (IIoT). However, availability and performance issues may limit IoT usage on the shop floor. Several IoT and IIoT initiatives can be applied on the factory floor to improve processes, also allowing the inclusion of less reliable equipment. Therefore, there are several implementation approaches, wireless being the most used one due to it is deployment flexibility and centralized management. We analyse a real shop floor environment, identifying opportunities for using IIoT systems and equipment such as LoRaWAN technologies. Our results show that the possibility of improving process automation and monitoring using simple IIoT devices in Small and Medium-sized Enterprisess (SMEs) is still far from the Industry 4.0 level.
