Abstract. Currently there is a big trend to watch different variables for racing horses. There is great interest to monitor their condition in the race. This monitoring leads to the optimization of the needs of race horeses, which improves their final outputs. It is important to many countless indicators such as temperature, humidity, pressure, heart rate and many other to be monitored. It is therefore necessary to define a simple system for transferring the recorded data. This system must be reliable, flexible and especially efficient. Due to the the need for fast data transfer this technology must be wireless. The basis therefore is to create a so-called "multiple-sensor network". This network must allow for variability and allow mesh communication. The proposed network must then allow forwarding of messages, because each transmitter is also the receiver (repeater function). A survey was conducted on the current applicable technology. Eventually, the IQRF technology has been selected that exactly matches the specified criteria. The IQRF technology operates at a frequency of 868 MHz, which corresponds to the ISM868 band (Industrial, Scientific and Medical). IQRF mesh allows communication and is suitable for distances of tens to hundreds of meters. Its dimensions are small (about 2 cm long, 1 cm wide and 0.25 cm high), allowing seamless integration. It has been found that it is necessary to place the track stationary points. However, it is not necessary to solve the remote transmitter that would send its information which is identified from these stationary points. Because it is mesh communication, each loop element communicates with each other and does not require other transmit interfaces.

“…It is also possible to create an IQRF gateway by utilizing an open source package, IQRF gateway daemon. The IQRF gateway can be then implemented from a Linux-based machines like Raspberry Pi [38]. Besides, IQRF software development kit (SDK) is also provided to support machines without any operating system such as single-board computers (Arduino, chipKIT, etc.…”

In recent years, there has been a growing interest in building smart cities based on the Internet of Things (IoT) technology. However, selecting a low-cost IoT wireless technology that enables low-power connectivity remains one of the key challenges in integrating IoT to smart cities. In this context, the IQRF technology offers promising opportunities to provide cost-effective solutions. Yet, in the literature, there are limited studies on utilizing IQRF technology for smart city applications. Therefore, this study is aimed at increasing the awareness about the use of IQRF technology in IoT-based smart city development. For this purpose, a review of smart city architectures along with challenges/requirements in adopting IoT for smart cities is provided. Then, some of the common cost-effective IoT wireless technologies that enable low-power consumption are briefly presented. Next, the benefits of IQRF technology over other technologies are discussed by making theoretical comparisons based on technical documentations and reports. Moreover, the research efforts currently being undertaken by the authors as a part of ongoing project on the development of IoT-based smart city system in Gjøvik Municipality, Norway, are conceptually introduced. Finally, the future research directions are addressed.

“…This paper describes the measurement of environmental quantities in the laboratories of the authors' department and in the Grammar School and Secondary School of Electrical Engineering and Computer Science, Frenštát pod Radhoštěm. For this purpose, a Room Measurement of Carbon Dioxide (RMCD) device was developed using IQRF R technology described in [7,8] for transmitting measured environmental data. For the transmission of information from the measuring nodes, we decided to use wireless technology, which allows bi-directional communication in the MESH topology due to possible extension of the monitoring system with control elements.…”

The article describes the development and implementation of a complex monitoring system for measuring the concentration of carbon dioxide, ambient temperature, relative humidity and atmospheric pressure. The presented system was installed at two locations. The first was in the rooms at the Department of Cybernetics and Biomedical Engineering, Faculty of Electrical Engineering and Computer Science, VŠB-Technical University of Ostrava. The second was in the classrooms of the Grammar School and Secondary School of Electrical Engineering and Computer Science in Frenštát pod Radhoštěm. The article contains a detailed description of the entire measurement network, whose basic component was a device for measuring carbon dioxide concentration, temperature and relative humidity in ambient air and atmospheric pressure via wireless data transmission using IQRF® technology. Measurements were conducted continuously for several months. The data were archived in a database. The article also describes the methods for processing the data with statistical analysis. Carbon dioxide concentration was selected for data analysis. Data were selected from at least two different rooms at each location. The processed results represent the time periods for the given carbon dioxide concentrations. The graphs display in percent how much of the time students or employees spent exposed to safe or dangerous concentrations of carbon dioxide. The collected data were used for the future improvement of air quality in the rooms.
