Solution Overview
Problem
Existing mobile communication systems face challenges in balancing high data rate transmission with low power consumption, especially in battery-operated devices that require long operating times and occasional high data transmission.
Innovation Solution
Implementing a dual-transceiver system in mobile communication devices, where one transceiver supports high data rate transmission and another supports low power consumption, allowing the device to switch between them based on data transmission needs, thereby optimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a high data rate transceiver is used for data transmission, then the data transmission rate is improved, but the power consumption increases
Solution Approach 1:
The communication device is segmented into two distinct transceiver systems: a first transceiver optimized for high data rate transmission and a second transceiver optimized for low power consumption. This segmentation allows the device to selectively activate only the necessary transceiver based on current communication needs, thereby achieving high data rates when required while minimizing power consumption during idle or low-bandwidth periods.
2Reliability
If a high data rate connection is maintained in sleep mode, then the connection readiness is improved, but the power consumption remains relatively large
Solution Approach 1:
The system dynamically switches between two operational states: using the first transceiver when high data rate communication is active, and transitioning to the second transceiver when data transmission ceases. This dynamic adaptation allows the connection to maintain functionality while optimizing power consumption by deactivating the high-power first transceiver during idle periods and activating it only when data transmission is required.
3Productivity
If the first transceiver is continuously active to ensure immediate data transmission, then the productivity is improved, but the battery life decreases
Solution Approach 1:
Instead of continuous operation of the first transceiver, the system employs periodic activation controlled by a trigger mechanism. The second transceiver monitors for data transmission needs and periodically activates the first transceiver only when necessary. This periodic action ensures data transmission availability is maintained while dramatically reducing the cumulative power consumption, thereby extending battery life.
Data Source
AI summary
A data transmission method between at least two mobile communication devices is provided, a communication device comprising a first and a second transceiver. The first transceiver communicates with a transceiver of another device with a data rate higher than that of the second transceiver, and the second transceiver communicates with a transceiver of another device with power consumption level lower than that of the first transceiver. The device is configured to communicate with another communication device using the first transceiver when data is to be transmitted between devices; stop using the first transceiver when data transmission ceases, and communicate with another communication device using the second transceiver to set up the use of first transceiver when a need to send data arises.
