Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sensor processes multiple data streams for both transmission and reception across multiple carrier frequency bands, then compatibility with user terminals from different networks is improved, but device complexity and baseband unit requirements increase
Solution Approach 1:
The patent applies universality by designing a single baseband unit that can handle multiple carrier frequency bands (e.g., 850MHz, 1.9GHz, 2.1GHz, 2.6GHz, 3.5GHz) through a unified architecture. The baseband unit processes signals from different networks (PLMNs) using the same processing pipeline, eliminating the need for separate baseband units for each frequency band and network operator, thus reducing device complexity while maintaining broad compatibility
Solution Approach 2:
The patent merges multiple data streams from different carrier frequency bands into a single processed signal path. Instead of having separate processing channels for each frequency band, the system combines and processes all incoming signals through a unified baseband unit, reducing the overall complexity of the sensor while maintaining the ability to serve multiple networks
2Productivity
If a sensor uses high bandwidth input/output to handle multiple carrier frequency bands, then the ability to process multiple data streams is improved, but the overall device complexity and cost increase
Solution Approach 1:
The baseband unit is designed with universal functionality to handle multiple carrier frequency bands through a single processing pipeline. This multi-functional design allows the sensor to process data streams from 850MHz, 1.9GHz, 2.1GHz, 2.6GHz, and 3.5GHz bands without requiring separate high-bandwidth channels for each frequency, thereby maintaining productivity while reducing device complexity

AI summary
A method is provided of a sensor sensing a mobile user terminal for cellular radio telecommunications, the user terminal being associated with any one of a plurality of networks, each network having a distinct carrier frequency band for radio signals. The method comprises: broadcasting a common signal at each of multiple carrier frequency bands; the user terminal receiving the signal in the associated carrier frequency band of its network; the user terminal checking information in the received signal, and upon determining that the information is acceptable to allow connection to the sensor, the user terminal acknowledging to the sensor its receipt of the signal.
