Modular-CAPA-Based Communication Systems: Joint Activation and Beamforming Design
Turning antenna arrays on and off to send data faster and more efficiently
Researchers found that wireless systems using continuous antenna arrays can achieve full performance while activating only some portions of the array at a time. The key is choosing which parts to switch on and how to shape the signal beams — a problem the team solved with an algorithm that nearly matches the performance of always-on systems but uses far less power.
Mobile networks consume enormous amounts of energy, and antenna arrays are among the biggest culprits. By activating only necessary parts of an antenna and smartly directing signals, this approach cuts power use without sacrificing data speeds — a direct win for reducing both operating costs and emissions in wireless infrastructure.
