Location measurement of an object using radio networks for Industry 4.0 applications

Abstract: Indoor positioning methods using radio networks are investigated. Time Difference of Arrival (TDOA) method is studied deeply, and the main problems are revealed. Application of ultra-wide band (UWB) radio technology to TDOA method is discussed, and limitations to UWB receiver and transmitter are revealed. These results are of great importance for the organization of unmanned moving devices management in the paradigm of fully autonomous Fabric of the Future in Industry 4.0.

“…This input is then used to estimate the distance between the two elements. Also in this class of solution, the location may be estimated using a triangulation (i.e., at least 3 different transmitters) [13], [14]. In this case, the estimation is affected by the signal attenuation introduced by obstacles, which is reduced using higher frequency signals (e.g., UltraWideband -UWB), resulting in higher precision.…”
