ONE-TO-MANY AND MANY-TO-MANY RANGING USING NBA-MMS UWB PROTOCOLS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18212550 titled 'ONE-TO-MANY AND MANY-TO-MANY RANGING USING NBA-MMS UWB PROTOCOLS
Simplified Explanation
- The patent application discloses embodiments for one-to-many and many-to-many ranging using narrowband assisted (NBA)-multi-millisecond (MMS) ultra wideband (UWB) protocols. - An initiator device communicates with multiple responder devices by transmitting a control/initialization poll message via NB signaling to identify a ranging cycle. - The initiator device then transmits a first set of MMS segments corresponding to the control/initialization poll message. - After transmitting the first set of MMS segments, the initiator device receives multiple report frames from two or more responder devices via NB signaling. - Within the ranging cycle, the initiator device transmits a ranging results report message based on the received report frames via narrowband signaling.
Potential Applications
- Industrial automation - Asset tracking - Indoor positioning systems - Robotics - Smart agriculture
Problems Solved
- Efficient and accurate ranging between multiple devices - Improved communication reliability in challenging environments - Enhanced coordination and synchronization among devices - Reduced interference and power consumption
Benefits
- Enhanced ranging capabilities - Increased reliability in communication - Improved coordination among multiple devices - Reduced power consumption and interference - Enhanced performance in challenging environments
Original Abstract Submitted
Embodiments are disclosed for one-to-many and many-to-many ranging using narrowband assisted (NBA)-multi-millisecond (MMS) ultra wideband (UWB) protocols. Some embodiments include an initiator device that communicates with many responder devices. For example, the initiator device can transmit a control/initialization poll message via NB signaling that identifies a ranging cycle, and transmit a first set of MMS segments corresponding to the control/initialization poll message. The initiator device can receive a plurality of report frames from two or more responder devices via NB signaling subsequent to transmitting the first set of MMS segments, and transmit within the ranging cycle, a ranging results report message based at least on the plurality of report frames via narrowband signaling.
