The Wireless Power World Shanghai 2012 was held last month on Sept 12 -13 where many of the leading companies presented and attended.
It was evident at the show that all companies and industry groups are now driving to a common set of objectives addressing the fundamental needs of consumers. These consist of spatial freedom, simultaneously charging multiple devices, and addressing a wide power range for devices from smartphones to tablets and PCs. Spatial freedom is the new term for “loosely coupled” and more intuitive than the prior technical term.
Although the Wireless Power Consortium (WPC) was first in creating an interoperable specification to start the market, the adoption has been slow. Some of the basic limitations for consumers have been the “tightly coupled” or non-spatial freedom requiring consumers to precisely align their device on a charging pad, charging only one device at a time, and power to charge only a smartphone. While on my travels throughout Asia last month, I discovered that a number of tier 1 OEMs decided not to supply WPC based products not only due of those limitations but also because of unacceptable performance for low efficiency and generating too much heat.
There are now 3 industry groups driving these common objectives: WPC, A4WP, and the Consumer Electronics Association Working Group 4 (CEA WG4). The CEA WG4, where PowerbyProxi is one of the leading contributors, was formed over one year ago and took the lead in defining an interoperable specification for what the rest of the industry is now recognizing as the fundamental needs.
PowerbyProxi demonstrated working products and technologies at the Wireless Power World Shanghai 2012 which deliver the ultimate in spatial freedom and the ability to charge multiple devices simultaneously with its Proxi-3D and Proxi-2D charging platforms as well as the most miniaturized receivers that can fit into AA batteries.
Let me now your thoughts.
