A 50% Fractional Bandwidth, Wireless Power Communication System Achieving 6.78 Mbps at 13.56 MHz Carrier

Wireless-power transfer (WPT) has emerged as an important power delivery solution for many systems. In many of these systems, communication is equally important, but has typically been achieved through a non-WPT channel due to the historically low data rates of WPT channels. In this work, we demonstrate that WPT channels can support very high data rates through an experimental prototype that achieves an effective 50% fractional bandwidth of 6.78 Mbps on a 13.56 MHz carrier. This data rate is sufficient to stream high-definition (HD) video across a WPT link.
