Wireless Receiver Frequency Hopping Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data transmission methods for wireless peripheral devices using frequency hopping procedures face transmission delays and are infeasible when a single wireless receiver cooperates with multiple transmitters, as they require re-transmission through secondary channels and lack efficient master control power management.
Innovation Solution
The method involves re-transmitting data directly through secondary channels and switching the master control power of the frequency hopping procedure from the wireless transmitter to the receiver, allowing the receiver to issue acknowledgement packets with loadable information to control the transmitter, thereby reducing delays and enhancing control capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless transmitter re-transmits data through secondary channels after receiving channel change notification, then data transmission can continue, but transmission delay occurs
Solution Approach 1:
The receiver performs preliminary actions by storing channel change notifications in a buffer before the transmitter needs to respond. When the transmitter sends data through the primary channel, the receiver has already prepared the channel change information, allowing immediate re-transmission through secondary channels without waiting for the transmitter's response, thus eliminating transmission delay while maintaining data transmission continuity.
2Ease of operation
If the wireless transmitter controls the frequency hopping procedure, then transmission control is simplified, but the system becomes infeasible when a single receiver cooperates with multiple transmitters
Solution Approach 1:
The patent inverts the traditional control architecture by shifting the master control power from the transmitter to the receiver. The receiver now actively manages frequency hopping by sending channel change notifications to multiple transmitters, enabling a single receiver to coordinate with multiple transmitters efficiently. This inversion resolves the feasibility issue while maintaining operational simplicity through receiver-centric control.
Solution Approach 2:
The receiver is designed with multi-functionality to handle multiple transmitters simultaneously. It can store channel change notifications from different transmitters in a buffer, process frequency hopping control for multiple devices, and coordinate data transmission across primary and secondary channels. This universal design enables the receiver to manage complex multi-transmitter scenarios that were previously infeasible.
3Reliability
If the wireless receiver waits for transmitter confirmation before re-transmitting data, then transmission accuracy is improved, but transmission speed decreases
Solution Approach 1:
The receiver performs preliminary actions by buffering channel change notifications and preparing re-transmission data before the transmitter's confirmation is needed. When the transmitter sends data through the primary channel, the receiver has already prepared the channel change information and can immediately initiate re-transmission through secondary channels. This eliminates the waiting period while maintaining accuracy through proper channel coordination.
Solution Approach 2:
The patent implements a skipping mechanism where the receiver rushes through the confirmation waiting period by using buffered channel change notifications. Instead of waiting for the transmitter's confirmation before re-transmitting, the receiver skips this step by having pre-stored the necessary channel information, thereby significantly improving transmission speed without sacrificing accuracy.

AI summary
A data transmission method for use between a wireless transmitter and a wireless receiver of a wireless peripheral device is provided. In a frequency hopping procedure, the wireless transmission data is re-transmitted through a secondary transmission channel. Consequently, a transmission delay problem is reduced. Moreover, the wireless receiver issues a special acknowledgement packet with loadable information to the wireless transmitter. Consequently, the master control power of the frequency hopping procedure is switched from the wireless transmitter to the wireless receiver. In addition, the information control capability of the wireless receiver to control the wireless transmitter in the communication application level can be increased.
