Title: WIRELESS NETWORK POWER DISTRIBUTION AND DATA AGGREGATION SYSTEM AND ASSOCIATED APPLICATIONS
Abstract:
A wireless network power distribution and data aggregation system, along with associated applications, is disclosed. An exemplary system for wirelessly transmitting power to radio frequency (RF) energy harvesting sensor nodes of a wireless network system includes a pyramid-structured antenna array for wirelessly powering RF energy harvesting sensor nodes within a defined coverage area of the wireless network system. The pyramid-structured antenna array generates a radiation pattern from an orthogonal spread-spectrum signal that minimizes destructive interference between adjacent antennas of the antenna array. Each antenna of the antenna array can wirelessly transmit power to a respective sector of the defined coverage are.
