“…It opened up new directions in the market as well as in the scientific research. During the last years, many different use-cases for the IQRF were introduced, i.e., home automation [21]- [23]; radio telemetry at mining dumps [24]; wireless sensor networks with internet protocol interoperability [25]; distributed temperature and humidity measurement [26], [27]; underground large-scale remote monitoring [28]; detection of construction inclination [29], racehorse monitoring [30]; erosion of rock formation measurements [31]; city use-casepublic light management [32] or intelligent parking [33]; laboratory and student training in sensor networks [34], [35]; and many others.…”

Recent years brought many changes, which accelerated the development of different communication approaches and technologies. Nowadays, wireless technologies become the accelerators for a wide range of new applications. This paper focuses on the latest evolution of the promising wireless communication technology IQRF. For this aim, an indepth analysis together with experimental measurements and simulations are provided. We provide original results in selected indoor and outdoor scenarios, in which the important communication parameters and technological limitations are highlighted. Last but not least, the application field of IQRF is established together with a comparison with other relevant technologies.

“…The paper [5] describes the modeling of a protective net load using LVDT sensors and string potentiometers. The use of these elements for load monitoring has already been considered in [6], but the cost-effectiveness of this solution and the high degree of uncertainty of placing these sensors on these protective networks led us to further develop and implement a system based on accelerometer sensors. The fact that this monitoring system is functional is also demonstrated by the actual application of a similar system for the railways in Scotland, see [7].…”

A large number of rock formations in the Czech Republic and abroad directly threaten to damage objects or traffic along the roads located beneath these formations. For this reason, many such rock formations are stabilized using protective fences or dynamic barriers. There are several special sensors available on the market. However, there is no comprehensive monitoring system, including remote threshold settings, data processing, and alarm conditions. This statement is supported by extensive research in this area as well as information from major geotechnical companies that are interested in such a system and want to include it in their portfolio. The aim of the article is to describe the unique wireless monitoring system used to measure the geotechnical quantities we have developed. The design and implementation of systems used to measure protective fence states with accelerometers and slope shift with load anchor cells are presented. Wireless accelerometric sensors and load anchor cell sensors are proposed for both systems. To transfer data from the accelerometer sensor to a superior system, IQRF® technology is applied for the communication between the wireless nodes and the network coordinator under the IQMESH topology. The article includes a detailed description of the development of the accelerometric wireless sensor node and load anchor cell wireless sensor node. Three case studies are also discussed. The first case study focuses on the data implementation and assessment at a testing polygon at the village of Málkov. The second case study describes the data implementation and an assessment of the measuring system under operating conditions in Zbraslav, a municipality near Prague. The third case study describes the implementation and assessment of data from load anchor cell wireless nodes installed in realistic conditions on a supporting gabion wall next to a road. All communication between the sensors and with the IQMESH network coordinator and database was executed wirelessly. The data were archived in a MySQL database and it provides a data source for the assessment and visualizations using the Grafana SW system.
