Abstract
Methods and systems are described for generating a first filtered signal by passing signal energy in a first radio frequency (RF) spectral band associated with a signaling bandwidth of an ultra-wideband (UWB) RF signaling system, generating a second filtered signal by passing signal energy in a second RF spectral band associated with the signaling bandwidth of the UWB RF signaling system, generating a plurality of digitized streams of pulses by identifying RF pulses in a respective filtered signal above a respective predetermined threshold, generating at least one time-stamped tag data packet, based on decoding a valid over-the-air packet corresponding to a plurality of RF pulses received according to a known burst pattern, selecting a time-stamped tag data packet from the at least one received time-stamped tag data packet, formulating a network data packet based on the selected time-stamped tag data packet, and outputting the network data packet.
