“…Both the Narrowband Internet of Things (NB-IoT) and the fifth generation (5G) wireless network have considered positioning as an enabling technology and essential service in 3rd Generation Partnership Project (3GPP) Release 14 and Release 16, respectively [2], [3]. A mountainous environment is one of the typical deployment scenarios of 5G and NB-IoT [4], [5], in which the positioning service is also extremely important. Different from plain or city environments, the terrain in mountainous environments is complex and highly variable, so that large position errors caused by faults or anomalies may result in economic losses or even loss of life.…”

Reliable positioning services are extremely important for users in mountainous environments. However, in such environments, the service reliability of conventional wireless positioning technologies is often disappointing due to frequent nonline-of-sight (NLoS) propagation and poor geometry of available anchor nodes. Hence, we propose a unmanned aerial vehicle (UAV)-enabled positioning system that utilizes UAV's mobility to overcome the above challenges. In this article, we first analyze and model the major causes of service failures in the proposed system. In particular, a geometry-based NLoS probability model is established based on the digital elevation models (DEM) of realistic terrain for reliability analysis. Subsequently, we propose a reliability prediction method and derive the corresponding metric to evaluate the system's ability to provide reliable positioning services. Moreover, we also develop a voting-based method for the further enhancement of service reliability. Monte-Carlo simulations show that in mountainous environments, the proposed reliability prediction method could achieve a prediction accuracy that is at least 36.8% higher than that of the existing technique. In addition, in the experiments conducted in two typical valley scenarios, the proposed reliability enhancement method improves the service reliability of the proposed system by 23% and 29%, respectively. These numerical results demonstrate the strong potential of the proposed system and methods for reliable positioning.

“…One of the advantages of ZigBee/IEEE 802.15.4 technology is that it is the only mainstream technology able to operate outside the 2.4 GHz band [18]. Actually, some applications operate at the 868 and 900 MHz bands [41,[49][50][51], proving that XBee modules are already mature modules to be introduced at industrial applications.…”

Design and Performance of a XBee 900 MHz Acquisition System Aimed at Industrial Applications

et al. 2021

Wireless technologies are being introduced in industrial applications since they provide certain benefits, such as the flexibility to modify the layout of the nodes, improving connectivity with monitoring and decision nodes, adapting to mobile devices and reducing or eliminating cabling. However, companies are still reluctant to use them in time-critical applications, and consequently, more research is needed in order to be massively deployed in industrial environments. This paper goes in this direction by presenting a novel wireless acquisition system aimed at industrial applications. This system embeds a low-cost technology, such as XBee, not frequently considered for deterministic applications, for deploying industrial applications that must fulfill certain QoS requirements. The use of XBee 900 MHz modules allows for the use of the 2.4 GHz band for other purposes, such as connecting to cloud services, without causing interferences with critical applications. The system implements a time-slotted media access (TDMA) approach with a timely transmission scheduling of the messages on top of the XBee 900 MHz technology. The paper discusses the details of the acquisition system, including the topology, the nodes involved, the so-called coordinator node and smart measuring nodes, and the design of the frames. Smart measuring nodes are implemented by an original PCB which were specifically designed and manufactured. This board eases the connection of the sensors to the acquisition system. Experimental tests were carried out to validate the presented wireless acquisition system. Its applicability is shown in an industrial scenario for monitoring the positioning of an aeronautical reconfigurable tooling prototype. Both wired and wireless technologies were used to compare the variables monitored. The results proved that the followed approach may be an alternative for monitoring big machinery in indoor industrial environments, becoming especially suitable for acquiring values from sensors located in mobile parts or difficult-to-reach places.

“…In [11], the authors studied flexible and stretchable skin-like waterproof tags for marine species that can be connected using BLE. Olasupo [12] reports performance XBee and LoRa in rocky and mountainous environments. In [13], the authors have stated that WiFi-based long-distance networks (IEEE 802.11) and low-rate wireless personal area networks (IEEE 802.15.4) can be used to connect rural areas for agricultural applications (PAs can use this idea too).…”
