AI Technical Summary

Technical Problem

Existing technologies cannot assess transmission loss in short-range wireless communication in real time with high accuracy. In particular, the assessment accuracy is insufficient under dynamic weather changes and obstacle obstruction. Moreover, existing models have a large number of parameters and high inference overhead, making it difficult to achieve lightweight and universal assessment on resource-constrained edge devices.

Method used

An electromagnetic environment sensing system is constructed. By collecting and fusing datasets under controlled and variable conditions, a lightweight neural network model is used to learn the nonlinear mapping between environmental parameters and transmission loss, thereby achieving millisecond-level real-time assessment.

Benefits of technology

It achieves high-precision, low-overhead assessment of near-ground radio transmission loss within 1000 meters, is suitable for adaptive link optimization of edge devices, and improves the reliability and real-time performance of communication systems.
