This is because WiMAX or 3G/4G systems. Please note that radio regulation some interference mitigation device is required to be implemented for UWB has not been approved yet in Japan because of by the UWB regulation. Our developed sensor system can take any optional spectrum hole (non-activated within a portion of an interference problem with existing wireless systems in the wide radio spectrum) for the UWB transmission.
