Will 40% of U.S. Households Use Wireless Charging by 2020?

More than 270 million households worldwide will be using wireless charging technology by 2020, including nearly 40 percent of households in the United States and over 20 percent  in Europe, according to Juniper Research.

The primary barrier to market for wide-area charging technologies is regulatory requirements, such as the U.S.  Federal Communications Commission Code of Federal Regulations part 15, which stipulates that output from radio transmitters operating at frequencies of 45kHz and above cannot emit more than one watt of output power.

This severely limits the transmission of power over distance. For power transfer to be quick enough for most mobile computing devices, which typically charge at between 5 and 15 watts, substantially higher output power would have to be allowed.

That might be a key obstacle. The solution, of course, is not to transmit at a distance, but only in close proximity, as with charging furniture. Such limitations are one reason why Low Power Wide Area standards for Internet of Things devices will include batteries.
