“…To obtain the transit time, the sensor sends a frame while specifying the send time. After receiving the frame the particular anchor determines the time of receiving the frame and the expected time of sending the frame, which are included in the return frame [7]. After receiving the return message, the sensor determines the transit time taking into account the time needed for operations performed by the anchor.…”

This paper discusses two ways of measuring the distance between the transmitter and the receiver using UWB technology, then identifies their advantages and disadvantages. The method of calculating the position is presented together with the method of predicting errors based on room geometry. The hardware configuration of the transmitter and receiver systems included in a location system based on UWB technology is explained. Bluetooth technology is discussed, which is used to connect the location system with the environmental monitoring system.

“…This phenomenon is especially noticeable in the example of water, the high percentage of which in living organisms makes them perfect for detecting people and animals in closed rooms [4,5]. The strength of radio signals measured between transmitters and receivers with the line of sight of the devices intact compared to the strength of the signal resulting from the introduction of an obstacle or interference is a measure that allows determining the presence of a human despite the absence of any electronic device transmitting a signal (e.g., as in the case of traditional triangulation) [6]. With a certain tolerance, they also allow the detection of inanimate elements of the environment, but it is strongly dependent on the material they are made of.…”

This article presents research results on a smart building prediction, navigation and asset management system. The main goal of this work was to combine all comfort subsystems, such as lighting, heating or air conditioning control, into one coherent management system supported by navigation using radio tomographic imaging techniques and computational intelligence in order to improve the building’s ability to track users and then maximize the energy efficiency of the building by analyzing their behavior. In addition, the data obtained in this way were used to increase the quality of navigation services, improve the safety and ergonomics of using the room access control system and create a centralized control panel enriched with records of the working time of individual people. The quality of the building’s user habit learning is ensured by a network of sensors collecting environmental data and thus the setting values of the comfort modules. The advantage of such a complex solution is an increase in the accuracy of navigation services provided, an improvement in the energy balance, an improvement in the level of safety and faster facility diagnostics. The solution uses proprietary small device assemblies with implementation of popular wireless transmission standards such as Bluetooth, Wi-Fi, ZigBee or Z-Wave. These PANs (personal area networks) are used to update and transmit environmental and navigation data (Bluetooth), to maintain the connection of other PANs to the master server (Wi-Fi) and to communicate with specific end devices (ZigBee and Z-Wave).

“…Radio tomography aims to obtain a cross-section of the examined object in the most non-invasive way possible, i.e. without affecting the internal structure of the object [2,14]. One of the media is about electromagnetic radiation.…”
