RF Signal Extender Protocol Filtering for Wireless Control Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The RF signal coverage area in conventional wireless control systems is limited, preventing control commands and operational status data transmission when devices move out of range, and is further compromised by interference from other wireless control systems.
Innovation Solution
An RF signal extender is placed in the overlapping area between the coverage areas of two electronic devices, receiving, analyzing, and re-transmitting RF signals that adhere to the communication protocol, while discarding non-compliant signals to prevent interference, using a data register to manage signal compilation and transmission.

Engineering Contradiction Analysis
1Area of stationary object
If RF signals are transmitted between electronic devices, then control commands and operational status data can be transmitted, but the RF signal coverage area is limited and transmission fails when devices move out of range
Solution Approach 1:
An RF signal extender is introduced as an intermediary device between the first and second electronic devices. The extender receives RF signals from one device, analyzes them to retrieve data, determines protocol compliance, and transmits the signals to the other device. This mediator extends the effective communication range beyond the limited coverage areas of the original devices while maintaining reliable transmission through protocol validation.
2Area of stationary object
If RF signals are transmitted across extended coverage areas, then the operable area of the wireless control system is expanded, but interference from other wireless control systems increases
Solution Approach 1:
The RF signal extender acts as a protocol-compliant intermediary that filters and validates all transmitted signals. By analyzing received signals and determining whether they follow the wireless control system's RF communication protocol before re-transmission, the extender prevents non-compliant signals from causing interference, thus enabling extended coverage without proportionally increasing harmful interference.
Solution Approach 2:
The protocol analysis and validation mechanism converts potentially harmful interference signals into beneficial filtered transmissions. Non-compliant signals that would normally cause interference are identified and blocked, while compliant signals are properly re-transmitted, thus turning the challenge of extended coverage into an opportunity for improved signal quality and reduced interference.

AI summary
A method of extending RF signals in a wireless control system which includes a first electronic device (10), a second electronic device (20), and an RF signal extender (30). RF signal coverage areas of the electronic devices partially overlap, and each of the electronic devices is out of the RF signal coverage area of the other one. The RF signal extender (30) is in an overlapping area between the RF signal coverage areas, and the electronic devices are in an RF signal coverage area of the RF signal extender (30). The method includes the steps of: receiving an RF signal with the RF signal extender (30); analyzing the received RF signal to retrieve the data carried therein; and compiling the data into an RF signal for transmission if the retrieved data follows an RF communication protocol of the wireless control system. Whereby, a total RF signal coverage area can be expanded, and interferences can be reduced.
