Given a sequence of images of the wireless environment, can the mmWave/sub-THz basestation proactively predict future line-of-sight (LOS) link blockages?  Our machine learning-based solution can leverage the sequence of visual data to predict whether or not a future blockage will happen.


This paper provides the first real-world evaluation of using visual (RGB camera) data and machine learning for proactively predicting millimeter wave (mmWave) dynamic link blockages before they happen. Proactively predicting line-of-sight (LOS) link blockages enables mmWave/sub-THz networks to make proactive network management decisions, such as proactive beam switching and hand-off) before a link failure happens. This can significantly enhance the network reliability and latency while efficiently utilizing the wireless resources. To evaluate this gain in reality, this paper (i) develops a computer vision-based solution that processes the visual data captured by a camera installed at the infrastructure node and (ii) studies the feasibility of the proposed solution based on the large-scale real-world dataset, DeepSense 6G, that comprises multi-modal sensing and communication data. Based on the adopted real-world dataset, the developed solution achieves ~90% accuracy in predicting blockages happening within the future 0.1s and ~80% for blockages happening within 1s, which highlights a promising solution for mmWave/sub-THz communication networks.

Proposed Solution

This figure presents the proposed architecture for vision-aided future blockage prediction. The raw visual data is first processed to enhance the images captured during night or low-light scenario. The processed sequence of images are then passed through the proposed deep neural network architecture consisting of a object detection model and recurrent neural network to predict the future blockage.
