Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional positioning systems use higher-bandwidth signals to achieve more accurate positioning, then measurement precision improves, but spectral efficiency deteriorates
Solution Approach 1:
The patent combines positioning and communications functions into a single joint waveform, allowing both functions to share the same spectral resources simultaneously. This merging eliminates the need for separate dedicated positioning signals, achieving high positioning accuracy while improving spectral efficiency by utilizing the same bandwidth for dual purposes.
Solution Approach 2:
The joint positioning-communications waveform serves multiple functions simultaneously: it enables precise positioning measurements, carries communication data, and provides synchronization. This multi-functionality allows the system to achieve accurate positioning without requiring additional dedicated spectral resources, as the same signal performs multiple roles.
2Reliability
If legacy radio systems use dedicated spectrum for positioning and communications, then reliability improves, but device complexity and infrastructure requirements worsen
Solution Approach 1:
The system merges positioning and communications into a unified joint waveform processing framework. This consolidation maintains reliable positioning performance by using the same robust signal for both functions, while reducing infrastructure complexity by eliminating the need for separate dedicated positioning signal infrastructure and reducing the number of independent signal processing chains.
3Productivity
If traditional systems support higher user densities, then productivity improves, but measurement precision deteriorates due to spectral limitations
Solution Approach 1:
The joint waveform enables the system to support higher user densities by allowing communication and positioning to share spectral resources. Multiple users can simultaneously utilize the same waveform for both communication and positioning, improving productivity and user density support while maintaining positioning precision through the robust joint signal structure.

AI summary
A hyper-precise positioning and communications (HPPC) system and network are provided. The HPPC system is a next-generation positioning technology that promises a low-cost, high-performance solution to the need for more sophisticated positioning technologies in increasingly cluttered environments. The HPPC system is a joint positioning-communications radio technology that simultaneously performs relative positioning and secure communications. Both of these tasks are performed with a single, co-use waveform, which efficiently utilizes limited resources and supports higher user densities. Aspects of this disclosure include an HPPC system for a network which includes an arbitrary number of network nodes (e.g., radio frequency (RF) devices communicating over a joint positions-communications waveform). As such, networking protocols and design of data link and physical layers are described herein. An exemplary embodiment extends the HPPC system for use with existing cellular networks, such as third generation partnership project (3GPP) long term evolution (LTE) and fifth generation (5G) networks.
