This paper presents a new concept of wireless grid to realize battery-less sensor networks in indoor environments. In this environment, multiple wireless energy transmitters are distributed on the ceiling, and activate battery-less sensors located anywhere in the field. Carrier shift diversity is introduced to remove huge received power attenuation due to mutual interference between the target received signals having the same frequency. Moreover, antenna directivity is optimized under… CONTINUE READING
