The aim of the study was to measure the performance of RFID technology in fertilizers environment, to determine if RFID is reliable mean for identification at fertilizers manufacturer. During the research, authors were focused on examination of reading quality defined by two key performance indicators i.e. read rates and distances of reliable reading of RFID tags applied on pallets of sacks and bigbags filled with fertilizers. 20 different fertilizers were considered what consisted the whole population of fertilizers being manufactured by a company. 16 setups were experimented for each type of fertilizer. RFID was read for assumed distance and through assumed barriers for 14 fertilizers. Assumptions for reliable operation of RFID were concluded, as well as some limitations of the technology.

This paper describes a prototype implementation of a wireless sensor network allowing for the application of the Industry 4.0. concept. It discusses both the requirements for wireless sensor networks for industrial applications as well as ways of their development. Operating modes of wireless sensor network elements enabling implementation of the indicated requirements are described in detail. Authors also identify the main differences between the proposed structure and communication protocol and other commercially available protocols such as LoRaWAN, Sigfox, Bluetooth Low Energy, or ZigBee. The proposed solution is based on the use of wireless DASH7 protocol operating in the 433MHz band whose design framework and architecture are presented. The paper also discusses the results of DASH7 network functional tests, including the range and energy efficiency of the prototype network.

The paper is a study of an active sensory technology network with a new DASH7 protocol. The main aim was to establish the basis for implementing localization of moving objects in real time. Due to its low power consumption, long range, and good permeability resulting from the application of the DASH7 protocol, the technology under analysis can contribute to the development of a system of real-time localization equipped with advanced sensory features, while maintaining low manufacturing and implementing costs. An analysis of 433MHz signals, due to their multipath nature and the dynamic propagation environment, must be carried out in real time. This computational complexity of the application determines the use of approximate (asymptotic) methods.

The aim of the study was to determine the effectiveness of the use of RFID technology in selected processes at store with construction materials of the one of DIY retail network in Poland. During the research, author was focused on examination the effectiveness of the use of RFID tags and determination the efficiency of the process compared with traditional barcodes or manually performed actions. For the purpose of the study, 120 000 items within the store had been marked with RFID tags, all hardware components of the system were selected and connected with the existing IT environment through the use of dedicated applications and interfaces. Results of this study confirmed the high efficiency of RFID technology while pointing to problematic areas and products, requiring individual approach and carry out further tests. The study also showed "weaknesses" on the side of the retail network, which in the case of a decision to the full implementation must be subjected to a thorough change. Among of these areas the most important are: IT environment, construction of trolleys, the design of some of the shelves and the course of selected processes.
