Abstract

A feedback-based approach is proposed to achieve phase-frequency synchronization among physically isolated sensors. This will enable forming a distributed phased array to significantly increase the communication range between energy-limited sensor fields and the central information collector. A three-element distributed phased array is prototyped based on a 60-GHz wireless sensor network. A 9.2 dB of distributed beamforming gain is demonstrated.
