Streaming On A Wireless Power Connection

18.09.2017 | North Carolina State University | news.ncsu.edu

Researchers from North Carolina State University have developed a system that can simultaneously deliver watts of power and transmit data at rates high enough to stream video over the same wireless connection.

Wireless power transfer technologies use magnetic fields to transmit power through the air. To minimize the power lost in generating these magnetic fields, you need to use antennas that operate in a narrow bandwidth – particularly if the transmitter and receiver are inches or feet apart from each other.

Wireless data transfer

Because using a narrow bandwidth antenna limits data transfer, devices incorporating wireless power transfer have normally also incorporated separate radios for data transmission. And having separate systems for data and power transmission increases the cost, weight and complexity of the relevant device.

With this wider bandwidth, the NC State team then envisioned the wireless power transfer link as a communication link, adapting data-rate enhancement techniques, such as channel equalization, to further improve data rate and data signal quality.
