Radio Data Transmission Error Correction via Additional Telegrams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio transmission standards for building sensor networks, such as OMS, do not provide for error correction methods, limiting the transmission range and requiring higher power consumption, which is impractical for battery-operated devices.
Innovation Solution
Implementing an additional, non-standard-compliant telegram containing error correction data alongside standard-compliant telegrams to enhance error correction capabilities without altering the standard, allowing for greater transmission range and reduced power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard-compliant telegrams are used for radio transmission in building sensor networks, then compatibility between transmitters and receivers from different manufacturers is ensured, but error correction capabilities are lacking, limiting transmission range
Solution Approach 1:
The transmission system is segmented into two distinct parts: standard-compliant telegrams for ensuring compatibility and additional non-standard telegrams for providing error correction data. This segmentation allows each part to fulfill its specific function independently while working together to resolve the contradiction between reliability and transmission range.
Solution Approach 2:
An intermediary error correction mechanism is introduced in the form of additional telegrams that carry redundancy data. These intermediary elements mediate between the standard-compliant transmission protocol and the requirement for extended transmission range, enabling error correction without modifying the original standard.
2Length of stationary object
If higher transmission power is used to achieve greater transmission range, then error-free transmission over larger distances is possible, but battery consumption increases, which is impractical for battery-operated devices
Solution Approach 1:
Error correction data is prepared and transmitted in advance alongside the main data telegram. By performing error correction preliminarily through redundant encoding, the system avoids the need for retransmissions and high-power boosts, enabling extended transmission range with moderate, sustainable power consumption.
3Reliability
If error correction data is integrated within the standard telegram structure, then error correction is achieved, but the standard itself must be modified, reducing compatibility
Solution Approach 1:
The solution segments error correction functionality into separate additional telegrams rather than integrating it into the standard telegram structure. This segmentation preserves standard compatibility while providing error correction capabilities through optional supplementary transmissions.
Solution Approach 2:
The additional error correction telegrams serve multiple functions: they provide redundancy for error correction, maintain compatibility with existing standards, and can be optionally implemented without forcing standard modification. This multi-functionality resolves the contradiction between reliability improvement and standard compatibility.

AI summary
A method 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 standard-compliant telegram (1) according to a defined standard. In order to enable error correction independent of the standard, it is provided that at least one further telegram (2) is sent and/or received, wherein the further telegram (2) contains an error correction data set with error correction data (4) for the data (3) contained in the standard-compliant telegram (1), which, due to redundancy, allows error correction of the data (3) in the event of transmission errors.
