Radio Telegram Error Correction for Long-Range, Low-Power Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio transmission standards for building consumption, sensor, and actuator data in local building networks do not provide error correction methods, limiting transmission range and requiring higher power consumption, which is often not feasible due to battery limitations and regulatory constraints.
Innovation Solution
Incorporating error correction data in a proprietary area of the telegram, positioned relative to the end, allows for error correction without altering the standard, enhancing transmission robustness and range while maintaining compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If error correction methods are not used in standard telegrams, then standard compliance is maintained, but transmission range is limited and power consumption increases
Solution Approach 1:
The patent introduces an intermediary error correction data record that mediates between the standard-compliant telegram structure and the need for error correction. This intermediary component contains error correction data that can be processed to correct transmission errors without requiring changes to the standard telegram format, thus resolving the contradiction between maintaining standard compliance and achieving reliable error correction.
Solution Approach 2:
The patent segments the telegram into distinct parts: the standard-compliant data area and a separate proprietary area containing the error correction data record. This segmentation allows the error correction functionality to be added independently without affecting the standard telegram structure, enabling error correction capability while maintaining standard compliance and avoiding increased power consumption.
2Reliability
If error correction data is added to the telegram, then transmission range and robustness are improved, but standard compliance may be compromised
Solution Approach 1:
The patent divides the telegram into a standard data area that maintains compliance with existing standards and a separate proprietary area that contains the error correction data record. This segmentation allows the proprietary area to carry error correction information without affecting the standard-compliant portions of the telegram, thus resolving the contradiction between improving transmission robustness and maintaining standard compliance.
Solution Approach 2:
The error correction data record acts as an intermediary element that bridges the gap between standard compliance and enhanced error correction capabilities. It provides the necessary error correction functionality while being structured in a way that does not interfere with or violate standard telegram requirements, allowing both standard compliance and improved reliability to coexist.
3Length of stationary object
If higher transmission power is used to extend range, then transmission distance is improved, but power consumption and battery life are worsened
Solution Approach 1:
The patent applies error correction data in advance to prevent transmission errors before they occur or to correct them immediately upon reception. This preliminary error correction action ensures reliable transmission over extended ranges without the need to increase transmission power, thus extending transmission range while avoiding increased battery consumption.

AI summary
Methods for the radio transmission of data and devices set up for carrying out the method are described, in which the data are sent and/or received in a telegram (1) according to a defined standard, wherein the standard in the telegram (1) provides a standard data area (3) for transmitting data (7) and a proprietary area (4) for transmitting manufacturer-specific data (8). To enable error correction, it is proposed that an error correction data set (9) containing error correction data (10) for the telegram (1) be transmitted in the proprietary area (4), which, due to redundancy, allows error correction of the data (7) and/or the manufacturer-specific data (8) in the event of transmission errors, wherein this error correction data set (5) is located at a position in the telegram (1) defined relative to the end of the telegram (1).
