Solution Overview
Problem
First responders require a device that can efficiently receive and process signals from different telecommunications protocols without carrying multiple devices, while maintaining energy efficiency and minimizing data loss or corruption during protocol transitions.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device continuously processes samples to maintain timing synchronization, then timing synchronization is improved, but energy consumption increases
Solution Approach 1:
The system dynamically switches between continuous processing mode and selective processing mode based on protocol requirements. In continuous processing mode, all digital blocks process samples continuously to maintain timing synchronization. In selective processing mode, only specific digital blocks are activated based on the particular protocol being received, reducing energy consumption while maintaining necessary synchronization.
Solution Approach 2:
The baseband processor changes operational parameters by selectively enabling or disabling digital blocks based on the detected protocol. This parameter change allows the system to adapt its processing intensity and energy consumption level to match the specific timing requirements of different communication protocols.
2Adaptability or versatility
If the device switches modes in real time to process different protocols, then adaptability is improved, but data loss or corruption may occur
Solution Approach 1:
The system performs preliminary actions by detecting the protocol type before fully switching processing modes. The baseband processor identifies the incoming protocol and prepares the appropriate digital blocks for processing, ensuring that the correct processing path is established before data transmission begins, thereby preventing data loss or corruption during mode transitions.
Solution Approach 2:
The baseband processor acts as an intermediary that manages the transition between different processing modes. It detects the protocol type and selectively activates the appropriate digital blocks, serving as a mediator between the incoming signal and the processing pipeline, ensuring smooth mode switching without data loss.
3Productivity
If multiple digital blocks are activated for protocol processing, then processing capability is improved, but processing delay increases
Solution Approach 1:
The processing system is segmented into multiple independent digital blocks, each capable of handling specific protocol processing tasks. The baseband processor selectively activates only the necessary segments (digital blocks) based on the detected protocol type, rather than activating all blocks simultaneously. This segmentation allows the system to maintain high processing capability when needed while reducing processing delay by activating only the minimum necessary components.
4Use of energy by moving object
If the device holds digital blocks in continuous reset state, then energy efficiency is improved, but synchronization accuracy deteriorates
Solution Approach 1:
The system dynamically adjusts the reset state of digital blocks based on protocol requirements. For protocols requiring high synchronization accuracy, the system releases digital blocks from reset state and activates them appropriately. For protocols with less stringent timing requirements or during idle periods, the system maintains digital blocks in reset state to conserve energy. This dynamic adjustment resolves the contradiction between energy efficiency and synchronization accuracy.
