Solution Overview
Problem
Existing radiofrequency sensing technologies struggle to maintain accuracy under varying environmental conditions, as they fail to distinguish between variations caused by sensing targets and those induced by environmental changes, leading to decreased independence from environmental influences.
Innovation Solution
A configuration module that provides a reference relation between ambient parameters and received signal features, allowing for the determination of operating variables to enhance the independence of sensing results from environmental conditions by adjusting network device configurations based on ambient parameter values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radiofrequency sensing is performed in varying environmental conditions, then the sensing network can operate in diverse locations, but the accuracy of sensing results decreases due to environmental variations
Solution Approach 1:
The patent applies parameter changes by establishing reference relations between ambient parameters (temperature, humidity, pressure) and received signal features under different environmental conditions. The configuration module determines operating variable values by comparing current ambient parameters against reference values, allowing the sensing network to adapt its signal processing parameters dynamically. This resolves the contradiction by enabling the system to maintain sensing accuracy across diverse environments through parameter adjustment rather than being constrained to fixed environmental conditions.
Solution Approach 2:
The patent implements preliminary action by pre-establishing reference relations between ambient parameters and signal features during a configuration phase before actual sensing operations. The configuration module stores these reference relations and uses them to determine appropriate operating variable values when environmental variations are detected during sensing. This preliminary preparation allows the sensing network to quickly adapt to environmental changes without compromising accuracy, thus resolving the contradiction between operational flexibility and sensing accuracy.
2Measurement precision
If environmental parameters are monitored and used to adjust sensing operations, then sensing accuracy improves, but the system complexity increases
Solution Approach 1:
The configuration module serves multiple functions: it stores reference relations, monitors ambient parameters, determines operating variable values, and configures network devices. By consolidating these functions into a single multi-functional module rather than separate components for each function, the patent reduces overall system complexity while still achieving improved sensing accuracy through environmental compensation.
Solution Approach 2:
The sensing network performs self-configuration through the configuration module, which automatically determines operating variable values based on current ambient conditions and reference relations without requiring manual intervention. The system self-adjusts to environmental variations, eliminating the need for complex external configuration systems while maintaining high sensing accuracy.

AI summary
The invention refers to a configuration module 100 for configuring a radiofrequency sensing network 200 with network devices 210, 220, 230, 240. The configuration module comprises a providing unit 101 for providing a reference relation between a) an ambient parameter value, wherein the ambient parameter correlates with a propagation property of an ambient medium for radiofrequency signals, and b) a received signal feature value indicative of a signal that has propagated through the ambient medium and has been received by the network device. A further providing unit 102 provides a configuration value of the ambient parameter indicative of a value of the ambient parameter at a configuration time, and a determining unit 103 determines a value of an operating variable associated with the network device based on the reference relation and the configuration value. This allows to achieve an increased independence of the sensing results from environmental conditions.
