Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems for M2M and IoT applications face challenges in balancing low electrical consumption with high throughput requirements, as ultra-narrowband systems limit data exchange capacity, while high-throughput systems consume excessive power and are costly, especially for battery-operated devices.
Innovation Solution
A terminal with both low- and high-throughput communication modules, where the high-throughput module is remotely controlled by a server using a shared identification code, activating only when necessary to conserve power and reduce costs by sharing the identification code among a group of terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If ultra-narrowband wireless communication systems are used, then electrical consumption is reduced, but maximum throughput is limited
Solution Approach 1:
The patent implements dynamic switching between ultra-narrowband communication mode and high-throughput communication mode based on real-time network conditions and data requirements. The terminal can adaptively select the appropriate communication mode, transitioning from static ultra-narrowband operation to dynamic mode selection that optimizes both energy consumption and throughput based on current operational needs
Solution Approach 2:
The patent segments the communication functionality into two distinct modules: an ultra-narrowband communication module for low-power operations and a high-throughput communication module for data-intensive tasks. This segmentation allows each module to operate independently in its optimal performance range, enabling the system to achieve low power consumption during normal operations while maintaining the capability for high-speed data transfer when required
2Productivity
If high-throughput wireless communication systems are used, then maximum throughput is increased, but electrical consumption becomes too high for battery-operated objects
Solution Approach 1:
The system dynamically activates the high-throughput communication module only when high data transfer rates are actually required, rather than maintaining it in a continuously active state. This dynamic activation strategy allows the terminal to achieve high throughput performance on-demand while minimizing energy consumption during normal low-data-requirement operations
Solution Approach 2:
The patent separates communication functions into distinct modules with different power characteristics. The high-throughput module is designed to be activated only for specific high-data-rate tasks, while the ultra-narrowband module handles routine communications. This functional segmentation enables optimized power management by matching the right communication technology to the right task
3Reliability
If each terminal has a personal identification code for high-throughput systems, then connectivity is ensured, but cost becomes too high for M2M or IoT applications
Solution Approach 1:
The patent implements a shared identification code mechanism where a single identification code serves multiple terminals within a group. This universal identification approach allows multiple low-cost terminals to access the high-throughput communication network without each terminal requiring its own expensive unique identifier, thereby reducing per-unit costs while maintaining network connectivity and access control
Data Source
AI summary
A method for controlling, via a terminal, a sleep mode of a first communication module of the terminal. The first communication module is configured to exchange data with a first wireless access network. The terminal includes a second communication module, which is configured to exchange data with a second wireless access network. The second communication module has a maximum data rate that is lower than a maximum data rate of the first communication module. When the first communication module is in sleep mode, the second communication module is configured to listen to a downlink between the second wireless access network and the terminal. When the terminal receives an activation request from the server via the second communication module, the first communication module is activated.
