EXPERIMENTAL INVESTIGATION OF UWB SIGNAL INTERFERENCE EFFECT BETWEEN UWB COMMUNICATION DEVICE AND VSAT

This paper presents the experimental investigation of the Ultra Wideband (UWB) signal interference effect between commercialized UWB communication device (UCD) and Very Small Aperture Terminal (VSAT). Recent research trend shows increase of interest to make use of UWB signal for Internet of Things (IoT) application. It is expected that IoT devices based on UWB technology increases in the future and can become unattended jammer to other services. The analysis involves two sets of experimental set up: i) UWB communication system is the interference victim from narrow band signal and other UWB transmission and ii) signal radiated from UCD devices using UWB signal interfere to other existing radio communication services which in this case a VSAT. The level of interference is evaluated based on the measured bit error rate (BER), round trip time (RTT) and carrier over noise ratio (C/N). The finding from this paper can be used as a guide for new interference mitigation techniques and spectrum planning purposes.
