Over-the-Air Computation Uses Radio Interference to Crunch Data
… Our setup used five radios acting as edge devices and one acting as a base station. The task involved training a neural network to perform image recognition over the air. …

How will over-the-air computation work in the field?
Over-the-air computation has in recent years moved from theory to initial proofs-of-concept and network test runs. Our research teams in South Carolina and Spain have built working prototypes that deliver repeatable results—with no cables and no external timing sources such as GPS-locked references. All synchronization is handled within the radios themselves. Our team at the University of South Carolina (led by Sahin) started with off-the-shelf software-defined radios—Analog Devices’ Adalm-Pluto. We modified the devices’ field-programmable gate array hardware inside each radio so it can respon
