Real-time OTA System

Under the umbrella of the AI-RAN Alliance, the Singapore University of Technology and Design (SUTD), in partnership with Keysight Technologies, used Aerial Testbed and Aerial Data Lake to implement a real-time OTA system that adaptively partitions an AI/ML image classification inference model between user equipment and infrastructure compute resources. The model split point is a function of the propagation channel which itself is determined by real-time spectrum sensing. This work shows how critical metrics such as privacy, end-to-end latency, energy efficiency and throughput can be optimized as a function of the channel.
