In plain terms
Power beaming is not a recognised radio service, so no spectrum is expected to be allocated for beaming power from space and no international numeric emission limit applies to it; the general duty not to cause harmful interference to radio services does apply.
The claim as recorded
Resolution ITU-R 910 records that wireless power transmission is not a defined radio service in the Radio Regulations and that there are no international regulations to regulate radiation from it, while also recording that under Nos. 15.12 and 15.13 administrations shall take all practicable and necessary steps to ensure WPT installations do not cause harmful interference to radiocommunication services. On that basis no allocation and no numeric emission limit for space-to-Earth power transmission is expected in the Radio Regulations; this is inferred from the Resolution, not read in Articles 5 or 21. Report SM.2392-1 describes 915 MHz, 2.45 GHz and 5.8 GHz as the main bands proposed at some administrations for WPT, not as power transmission allocations, and says beam WPT may be considered an ISM application even outside bands designated for ISM use.
Scope and limits
The identity of current primary incumbents in the 2.45 and 5.8 GHz bands was not confirmed from the Radio Regulations Article 5 tables and is NOT claimed here. SM.2392-2 (06/2026) is now held in full, but this record's statements from SM.2392-1 have not been re-read against it. The Radio Regulations are not held: the absence of an allocation and the non-application of Article 21 are inferred from Resolution 910, not read in Article 5 or Article 21, and which bands are ISM bands is set in Radio Regulations footnotes that are not held.
What it assumes
No assumptions are recorded against this claim.
Where it comes from
Resolution 910's own statement that WPT is not a defined service and is unregulated. Report SM.2392-1 section 2.9 (PDF p28, printed p26) catalogues solar power satellites among WPT applications and sets no power flux density limit. Its section 5 (PDF p33, printed p31) reads "The main frequency bands being proposed at some administrations for WPT applications are 915 MHz (917-920 MHz), 2.45 GHz (2 400-2 500 MHz), and 5.8 GHz (5 725-5 875 MHz)". Resolution 910 recognizing c) (PDF p2) cites Nos. 15.12 and 15.13. Report SM.2505-0 addresses only terrestrial short-range WPT.
