If your
smartphone has a charging pad instead of a cable and wall cube, then you're
using wireless power transfer. The
technology is also growing for charging household appliances, power tools and,
soon, electric vehicles. The ARRL Letter
reports on a study conducted by Region 1 of the International Amateur Radio
Union (which covers Europe, Africa and the Middle East)
on the impact of widespread use of WPT-EV, or wireless power transfer for
electric vehicles.
It concludes that current ITU and CEPT (European)
interference standards are inadequate and will result in "a widespread and
serious impact on radio communications operating in the vicinity" of WPT
systems, "given the planned density of WPT-Electric Vehicle Systems."
The report has been submitted to the appropriate working groups of both the
International Telecommunication Union (ITU) and the European Conference of
Postal and Telecommunications Administrations (CEPT) for further study.
