Wireless Power

Module Transfers Power and Gigabit Data Through Windows or Walls

MaxLinear, Inc. and jjPlus reported that Zinwell has integrated MaxLinear's AirPHY™ multi-gigabit modem technology with jjPlus's latest 65W magnetic resonant wireless power module into its 3rd generation ZRA-003 device, which can transfer power as well as gigabit data through glass windows or structural walls up to 20cm thick.

"With MaxLinear's AirPHY solution and the latest high power AirFuel Resonant solutions from jjPlus, Zinwell was able to meet the demanding cost, size and power requirements of service providers aiming to deploy gigabit wireless CPEs that can be self-installed on walls or windows."

The solution allows wireless internet service providers (WISPs) to provide a 4G/LTE or 5G millimeter wave wireless broadband service with gigabit speeds and deliver it without needing any wires to connect to an indoor Wi-Fi router. The device also eliminates the necessity of drilling holes and expensive professional installation.

Furthermore, with the new technology, consumers can readily connect an outdoor unit (ODU) with an indoor unit (IDU) for gigabit wireless speeds in their existing Wi-Fi home network, according to jjPlus

Resonant coupling happens when specifically designed magnetic “resonators,” consisting of a transmitter module and a receiver module, share the same resonant frequency. jjPlus developed its embedded power module after years of collaboration with its partner, WiTricity Corporation.

The power modules follow the AirFuel Alliance Resonant charging standards for high-efficiency wireless power transfer across much greater distances than other available technologies. The wireless power from JJPlus can also operate through window glass and other conventional building materials such as stone, concrete, brick, wood, plaster, and stucco.

The ZRA-003 can deliver 65W of output power, enough power for next-generation millimeter wave modems for 5G gigabit-speed internet services. Uniquely, its magnetic resonant technology can penetrate a 20cm concrete wall, which has never previously been demonstrated. Zinwell says that with easy installation, the ZRA-003 could potentially save service providers millions of dollars in truck deployments to set up new subscribers.

"Until now, consumer wireless power solutions were limited to about 15 Watts and could only transfer power up to 5 centimeters," said Will Torgerson, vice president and general manager of MaxLinear's Broadband Group.

"With MaxLinear's AirPHY solution and the latest high power AirFuel Resonant solutions from jjPlus, Zinwell was able to meet the demanding cost, size and power requirements of service providers aiming to deploy gigabit wireless CPEs that can be self-installed on walls or windows," concluded Torgerson.

“jjPlus develops magnetic resonant wireless power transfer solutions to enable various applications which require wireless power at a distance,” said Gary Chi, chief marketing officer of jjPlus Corporation. "Powering a gigabit wireless CPE through a concrete wall up to 20cm thick is a perfect example of our technology put to good use."

"In partnership with MaxLinear and jjPlus, Zinwell has successfully integrated the most innovative state-of-the-art technologies into the ZRA-003 to save wall drilling costs and time required to deploy 5G Fixed Wireless Access (FWA) internet services. With this powerful device, mobile network operators (MNOs) can enhance user experience of millimeter wave technology in residential and office environments," said Paul Wu, Senior director of sales and marketing of Zinwell.

Demonstration at CES 2019

Maslinear will hold a demonstration of the ZRA-003 device transferring gigabit data rates and 65W wireless power through a concrete wall during CES 2019, from January 8-11, 2019 in Las Vegas, at the Venetian® Las Vegas. Contact [email protected] for reservations.
