This paper presents the use of a low-power consumption relay approach based on a Rx duty cycled mode.The trade-off between relay power-consumption and reception sensitivity is analyzed and measured. Experimental validation is performed at 868MHz in outdoor environments to assess Node and Relay performances.

Development of fast, accurate, mobile and low-cost tools for food analysis is an important topic to mitigate food-borne diseases. In this paper, a portable sensors based on S11 and S21 of compact circularly polarized antennas is proposed. A low-cost and portable VNA analyser is used to perform measurement and analysis. Fruits are used to assess...
