Over the peri­od 28^th April until 11^th May 2021, the prepara­to­ry work for WRC-23 agen­da item 9.1b con­tin­ued in ITU‑R Work­ing Par­ty 5A (WP5A). An ITU‑R report is under devel­op­ment detail­ing the tech­ni­cal and oper­a­tional char­ac­ter­is­tics of the ama­teur ser­vices use of the band 1240 – 1300 MHz. As usu­al, the IARU par­tic­i­pat­ed in the meet­ing and deliv­ered key infor­ma­tion on the glob­al ama­teur band plans in this key microwave band and the rela­tion­ship to the radio nav­i­ga­tion satel­lite ser­vices (RNSS) oper­at­ing co-fre­quen­cy across the band. This infor­ma­tion is vital to ensure the ama­teur ser­vices are real­is­ti­cal­ly rep­re­sent­ed in the stud­ies as they move for­ward. For this rea­son the infor­ma­tion was for­mal­ly made avail­able to ITU‑R Work­ing Par­ty 4C for their con­sid­er­a­tion as they devel­op the tech­ni­cal studies.

The work on this top­ic will con­tin­ue through­out the year both in ITU‑R and in the region­al telecom­mu­ni­ca­tions organ­i­sa­tions and the IARU is com­mit­ted to ensure every group hears the ama­teur posi­tion on this impor­tant microwave band.
