“…In [115] and [116] , the authors show that Wi-Fi-based and Bluetooth based localization systems can be strongly affected by the interference from other wireless devices operating at 2.4 GHz bands. To mitigate the interference, Wi-Fi devices can use 802.11b and 802.11g/n standards which deploy direct-sequence spread spectrum and orthogonal frequency-division multiplexing signaling methods.…”

Social distancing plays a pivotal role in preventing the spread of viral diseases illnesses such as COVID-19. By minimizing the close physical contact among people, we can reduce the chances of catching the virus and spreading it across the community. This two-part paper aims to provide a comprehensive survey on how emerging technologies, e.g., wireless and networking, artificial intelligence (AI) can enable, encourage, and even enforce social distancing practice. In this Part I, we provide a comprehensive background of social distancing including basic concepts, measurements, models, and propose various practical social distancing scenarios. We then discuss enabling wireless technologies which are especially effective and can be widely adopted in practice to keep distance, encourage, and enforce social distancing in general. These technologies open many new solutions and directions to deal with problems in social distancing, e.g., symptom prediction, detection and monitoring quarantined people, and contact tracing. The companion paper Part II [1] surveys other emerging and related technologies, such as machine learning, computer vision, thermal, ultrasound, etc., and discusses open issues and challenges (e.g., privacypreserving, scheduling, and incentive mechanisms) in implementing social distancing in practice.

“…Mobile devices are equipped with RSS functionality. Hence, applications, such as user indoor positioning and navigation [24][25][26][27][28][29][30][31] and battery resource management [32], have emerged. In [24], the localization accuracy based on RSS was improved by using a priori information obtained from measurements.…”

“…In [28], a hybrid of a KNN algorithm and particle filtering algorithm [29] was adopted to improve the positioning accuracy of a robot in an indoor environment. The effect of Bluetooth interference with the wireless signals on the positioning accuracy was also investigated in [30]. This was performed by comparing the statistical approaches, such as the Weibull distribution and the probability of occurrence of an observed RSSI measurement.…”

The technologies of the fourth industrial revolution have the potential to make zero harm possible for the first time in the history of mining. In the journey toward zero harm, rock stress monitoring systems are important for the risk management process. Although communication systems for underground mining have improved significantly over the past two decades, it remains difficult to achieve reliable-all-the-time wireless communication in ultra-deep level underground mines. The aim of this study is to explore and test a smart phone network for communicating sensor data from the underground production environment to the surface. In this paper, the evaluation and performance over distance of a wireless communication system is performed in underground mining environments. The wireless system transmits the data collected from a sensor installed in a narrow reef stope, horizontal tunnel, and vertical shaft area of a mock underground mine. The evaluation was performed using the received signal strength of a mobile receiver over distance. The path loss coefficients of the underground mining environment were then derived for the measurement areas. The results show that a communication speed of 80 Mbps was achieved in a 60 m range, thus, indicating the potential for the support of applications requiring higher data rates.

“…When a tracked target is detected, the target's location is assumed in the proximity range marked by the IoT device. The basic idea of the fingerprinting method is to create a map of Received Signal Strength Indicator (RSSI) values for all possible locations of the target environment (Pei et al, 2017). To create such a map, the target area should be divided into equal cells and the RSSI value of the available signals should be recorded for each cell.…”

Nosocomial infections are fatal diseases caused by microorganisms in the hospital environment. It has mortality rates of up to 70% in intensive care units. The most important way to fight this infection is to pay attention to the hygiene of the assets in the hospital. Within the scope of this paper, an IoT-based real-time advanced asset tracking system has been implemented. This system consists of three main components: Hand Hygiene Surveillance System, Device Tracking System, and Infection Control System. Providing hand hygiene in hospitals is critical for the prevention of infections. The proposed Hygiene Surveillance System provides hand hygiene control in intensive care units and neonatal services, which are the areas with the highest risk of infections. Received signals from ultrawide-band (UWB) modules are processed by a designed positioning algorithm. While competitors are insufficient in many scenarios because of the 1-2 m precision positioning, the proposed system provides a solution in these scenarios with 20-25 cm precision. Antibiotic-resistant nosocomial infection is difficult to treat, contagious, and fatal. These patients are kept in quarantine. During the transportation of these patients, end-to-end hygiene control is required. By using the developed Infection Control System, these patients will be followed end-to-end in real-time. Our system consists 3 main layers. In the first layer, the distributed IoT devices in the environment collect the broadcasted UWB and Bluetooth Low Energy (BLE) signals from the mobile nodes. The strength of the received signals is sent to the second layer which is responsible for calculating the location of mobile nodes based on the received signals from different anchor nodes. The detected locations are sent to the thir layer which provide the real time tracking system for the web and mobile applications. In this layer different technologies such as JSON, Ajax, Server Sent Events, WebSockets, and RestFul technologies are used to deliver the real time location data to the users.
