Wireless sensor network system with wireless powering by time division operation at 5.8 GHz in a reusable rocket

Abstract

This paper demonstrates experimental evaluation results of a wireless sensor network system inside a reusable rocket for health monitoring system. The wireless sensor node is powered by microwave power transmission (MPT) to realize completely wireless, battery-less system. Both the MPT and wireless communication use same frequency, 5.8 GHz. Time division operation is utilized for the coexistence. Rectifier output DC power, received signal strength indicator (RSSI) and packet error rate (PER) is measured using the reusable vehicle test (RVT) to evaluate the feasibility of the coexistence.
