Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the IoT environment, existing technologies face challenges in efficiently transmitting real-time data using ultra wide band (UWB) channels, particularly in combining UWB and narrow band (NB) channels for effective data communication, which affects data throughput and power consumption.
Innovation Solution
A method for operating UWB devices that involves transmitting data through a UWB channel and receiving feedback information via an NB channel, allowing for efficient data processing and retransmission based on feedback, thereby optimizing data transmission and reception efficiency and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data is transmitted using only UWB channel, then data transmission speed is improved, but power consumption increases and reliability decreases
Solution Approach 1:
The patent segments the communication channel into two distinct channels: UWB channel for high-speed data transmission and NB channel for feedback and control signals. This segmentation allows the system to utilize the strengths of each channel independently, thereby reducing overall power consumption while maintaining high data transmission speed.
Solution Approach 2:
The system employs periodic feedback mechanisms where the NB channel is used to send feedback information at specific intervals. This periodic action on the NB channel allows for efficient error correction and retransmission without continuously activating high-power transmission, thus reducing overall power consumption.
2Speed
If data is transmitted using only UWB channel, then data transmission speed is improved, but transmission reliability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the NB channel is used to transmit feedback information from the receiver to the transmitter. This feedback includes acknowledgment signals and error correction information, which significantly improve transmission reliability by enabling retransmission of erroneous data packets.
Solution Approach 2:
The NB channel acts as an intermediary channel that facilitates reliable communication by carrying control and feedback signals. This intermediary channel provides a more stable and reliable path for essential control information, complementing the high-speed but less reliable UWB channel.
3Productivity
If dual-channel communication is implemented, then data throughput is improved, but device complexity increases
Solution Approach 1:
The patent designs the communication device with multi-functional capabilities where a single device can operate on both UWB and NB channels. This universality allows the device to handle different types of traffic (high-speed data on UWB, control/feedback on NB) through a unified architecture, thereby increasing data throughput without proportionally increasing device complexity.
