ITU‑R WP1A is a part of Study Group 1 in ITU, cov­er­ing Spec­trum Man­age­ment Issues. WP1A specif­i­cal­ly cov­ers spec­trum engi­neer­ing tech­niques. Of par­tic­u­lar inter­est to IARU is the work cur­rent­ly under way to con­sid­er the impli­ca­tions of the intro­duc­tion of Wire­less Pow­er Trans­mis­sion (WPT) tech­nolo­gies and appli­ca­tions, includ­ing the high-pow­er charg­ing of elec­tric vehi­cles. IARU’s con­cerns (and those of oth­er radio ser­vices) relate to the pos­si­bil­i­ty of spu­ri­ous emis­sions from WPT charg­ing sys­tems impact­ing the radio­com­mu­ni­ca­tions spec­trum. There are gen­er­al­ly two meet­ings of WP1A each year.

ITU Reports which have been pro­duced relat­ing to WPT can be found as follows:

ITU‑R SM.2303 —  Wire­less pow­er trans­mis­sion using tech­nolo­gies oth­er than radio fre­quen­cy beam

ITU‑R SM.2449 — Tech­ni­cal char­ac­ter­is­tics and impact analy­ses of non-beam induc­tive wire­less pow­er trans­mis­sion for mobile and portable devices on radio­com­mu­ni­ca­tion ser­vices

ITU‑R SM2451 — Assess­ment of impact of wire­less pow­er trans­mis­sion for elec­tric vehi­cle charg­ing on radio­com­mu­ni­ca­tion services

Work is also under way on a fur­ther Report/Recommendation on emis­sions from WPT sys­tems (Lim­its and mea­sures to mit­i­gate the impact of wire­less pow­er trans­mis­sion sys­tems on radio­com­mu­ni­ca­tions ser­vices oper­at­ing below 30 MHz).

IARU is active­ly involved in the ITU dis­cus­sions on WPT and has input a num­ber of papers on the subject.
