  • Bandwidth Dependence of the Propagation Channel in Circular Metallic BAN Environments

    Publication

    - IEEE Access - Year 2023

    In this paper, the bandwidth dependence of the propagation channel for Body Area Networks (BANs) in circular metallic environments is addressed and models are proposed to evaluate the appropriate short-term fading margins that should be considered as a function of the system bandwidth. The deployment of BANs in metallic indoor environments, such as ships, factories, warehouses and other similar environments, involves additional...

    - Year 2023

    In this paper, an analysis of depolarisation in Body Area Networks for Body-to-Infrastructure communications based on a measurement campaign in the 5.8 GHz band in an indoor environment is performed. Measurements were made with an offbody antenna transmitting linearly polarised signals and dualpolarised receiving antennas carried by the user on the body. A Normal Distribution with a mean of 2.0 dB and a standard deviation of 4.3...

  • Application of BAN Network to Increase Security in Transport Systems

    Publication

    - Year 2017

    In the article general characteristics of the BAN network with M2M communications are presented. These are networks that enable the implementation of wireless transmission of signals using special sensors located on the body or implanted subcutaneously. These sensors allow monitoring of different type life parameters of a human. In the next part of work there is proposed the implementation of BAN networks to transport systems as...

  • Mobility’s Influence on System Loss in Off-Body BAN Scenarios

    Publication

    - Year 2022

    In this paper, a measurement campaign for off body communications in an indoor environment is investigated for a set of on-body antennas. The channel impulse response was measured with the user approaching and departing from an off-body fixed antenna using two user dynamics, standing at fixed positions and walking. The processing of the measurement data allowed to evaluate system loss statistics. Different antenna configurations...

    - IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION - Year 2024

    In this article, an analysis of system loss and depolarization in body area networks (BANs) for body-toinfrastructure (B2I) communications based on a measurement campaign in the 5.8 GHz band in an indoor environment is performed. Measurements were performed with an off-body antenna transmitting linearly polarized signals and dual-polarized receiving antennas carried by the user on the body. A normal distribution with a mean of...

  • Tracking body movement for radio channel measurements in BAN with indoor positioning system

    Publication

    This paper presents indoor positioning system based on inertial navigation with additional distance measurements using UWB modems and map matching to increase accuracy and eliminate position drift. Such system may be used to track position of human body during radio channel measurements for body area networks. Performance of proposed system and limitations caused by inertial navigation are briefly described.

  • ANALIZA UWARUNKOWAŃ PROPAGACYJNYCH W RADIOWYCH SIECIACH BAN Z PRZESTRZENNYM ODBIOREM ZBIORCZYM

    W referacie przedstawiono analizę uwarunkowań propagacyjnych w radiowych sieciach BAN typu off-body z odbiorem zbiorczym przestrzennym. Średnia wartość tłumienia znajduje się w przedziale [54.42 dB; 64.28 dB], różnica wartości tłumienia dla anten nasobnych wynosi [0.69 dB; 8.76 dB], odchylenie standardowe tłumienia średniego zawarta jest w przedziale [6.46 dB; 7.39 dB], natomiast współczynnik korelacji pomiędzy zanikami szybkozmiennymi...
