Wireless Peripheral Data Transmission Frequency Hopping Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data transmission methods for wireless peripheral devices using frequency hopping procedures suffer from transmission delays and are infeasible when a single wireless receiver cooperates with multiple wireless transmitters.
Innovation Solution
The method involves dynamically selecting a secondary transmission channel with a frequency range farthest from the primary channel for re-sending data, and switching the master control power of the frequency hopping procedure from the transmitter to the receiver, allowing the receiver to control the transmitter.

Engineering Contradiction Analysis
1Reliability
If the wireless transmitter issues a primary transmission channel change notification through secondary transmission channels and re-sends data after receiver confirmation, then the frequency hopping procedure can be executed, but transmission delays occur
Solution Approach 1:
The wireless receiver proactively selects a secondary transmission channel in advance before the transmitter needs to send data. When the receiver detects it cannot receive data on the primary channel, it has already identified an alternative channel, eliminating the delay of selecting and notifying about channel changes during active transmission.
Solution Approach 2:
The control initiative is inverted from the transmitter to the receiver. Instead of the transmitter notifying the receiver about channel changes, the receiver autonomously selects the secondary channel and controls the frequency hopping procedure, reversing the traditional master-slave relationship in channel management.
2Adaptability or versatility
If the conventional data transmission method uses transmitter-controlled frequency hopping with notifications through secondary channels, then channel switching can be achieved, but the method becomes infeasible when a single wireless receiver cooperates with plural wireless transmitters
Solution Approach 1:
The wireless receiver performs self-service by autonomously selecting secondary transmission channels without requiring coordination or notifications from the transmitter. This self-determined channel selection eliminates the complexity of multi-transmitter coordination, as each receiver independently manages its own frequency hopping regardless of how many transmitters are present.
Solution Approach 2:
The receiver's channel selection mechanism becomes universal and applicable to multiple transmitters simultaneously. By making the receiver the autonomous controller that selects channels independent of transmitter identity, the system can seamlessly handle one or multiple transmitters without requiring different protocols or increased complexity.

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 transmitted through a dynamically selected secondary transmission channel. The frequency range of the dynamically selected secondary transmission channel is the farthest from the frequency range of the primary transmission channel. Consequently, the transmission efficiency is enhanced. Moreover, the wireless receiver issues a special acknowledgement packet with a 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.
