Encyclopedia of Information Science and Technology, Third Edition (2014, background): “However, the high cost of UWB equipment and network deployment results in its limited availability for positioning (Sahinoglu et al., 2008).”
Position Estimation via Ultra-Wide-Band Signals (2008, methodology): “Large bandwidths of UWB signals bring many advantages for positioning, communications, and radar applications [2]: • penetration through obstacles; • accurate position estimation; • high-speed data transmission; • low cost and low power transceiver designs.”
Indoor Tracking: Theory, Methods, and Technologies (2015, background): “In TW-TOA ranging, node A transmits a packet to node B, which replies by transmitting an acknowledgment packet to A after a known or measured response delay τ d [3].”
UWB Systems for Wireless Sensor Networks (2009, background): “FCC emission limits for indoor and outdoor UWB systems [41].”
Using Inertial Sensors for Position and Orientation Estimation (2017, unknown): “For a setup with M stationary transmitters, the position of the transmitter when transmitting the pulse k and the time when the pulse was transmitted can be estimated using multilateration [22, 43, 130, 125].”
