Current wireless communication systems face challenges in efficiently transceiving data between electronic devices, particularly in accurately measuring distance and ensuring secure ranging operations in IoT environments, where existing methods lack efficiency and reliability.
Innovation Solution
The proposed method involves an electronic device broadcasting or multicasting a ranging start message, receiving a ranging response message, and broadcasting or multicasting a ranging final message, which includes time information to measure distance, and optionally requesting time of flight measurements, interval information, scrambled timestamp sequences, and figure of merit for secure ranging operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wireless communication methods are used for data transceiving, then existing systems can maintain basic connectivity, but they lack efficiency and reliability in accurately measuring distance and ensuring secure ranging operations
Solution Approach 1:
The patent segments the ranging operation into distinct phases: a first phase for initial ranging messages and a second phase for final ranging messages with distance measurements. This segmentation allows each phase to be optimized independently, improving overall reliability while maintaining efficiency in data transceiving operations.
Solution Approach 2:
The patent implements preliminary actions by establishing secure connection information and ranging parameters before the actual ranging operation. This includes pre-configuring security parameters and connection details, which ensures reliable and secure ranging operations without compromising data transceiving efficiency during the actual operation.
2Measurement precision
If secure ranging operations are implemented with multiple messages and parameters, then ranging reliability and accuracy improve, but system complexity increases
Solution Approach 1:
The patent employs a base station that performs multiple functions: it manages secure connections, coordinates ranging operations, and provides centralised security parameter management. This multi-functionality allows accurate distance measurements through a unified system architecture, avoiding the complexity that would arise from distributed multi-device coordination.
Solution Approach 2:
The base station acts as an intermediary between electronic devices during ranging operations. It centralises the exchange of security parameters and ranging messages, which simplifies the overall system complexity while maintaining measurement precision through controlled and coordinated communication.
3Productivity
If electronic devices perform ranging operations independently without central coordination, then device autonomy is maintained, but network efficiency and power consumption deteriorate
Solution Approach 1:
The base station provides central coordination for ranging operations, receiving ranging requests from electronic devices and managing the exchange of ranging messages. This feedback mechanism improves network efficiency by optimising message timing and routing, while reducing individual device power consumption by eliminating redundant transmission attempts and coordination overhead.
