Msonkhano wa World Radiocommunication Conference 2023 (WRC-23), womwe unatenga milungu ingapo, unatha ku Dubai pa Disembala 15 nthawi yakomweko. WRC-23 idakambirana ndikupanga zisankho zokhudzana ndi mitu ingapo yodziwika bwino monga gulu la 6GHz, ma satellite, ndi ukadaulo wa 6G. Zisankhozi zidzasintha tsogolo la kulumikizana kwa mafoni. **Bungwe la International Telecommunication Union (ITU) linanena kuti mayiko 151 omwe ali mamembala adasaina chikalata chomaliza cha WRC-23.**
Msonkhanowu unapeza njira yatsopano ya IMT ya 4G, 5G ndi 6G yamtsogolo yomwe ndi yofunika kwambiri. Bande yatsopano ya pafupipafupi - bande ya 6GHz (6.425-7.125GHz) idaperekedwa kuti igwiritsidwe ntchito polumikizirana pafoni m'madera a ITU (Europe, Middle East & Africa, America, Asia-Pacific). Izi zimathandiza kuti anthu mabiliyoni ambiri m'maderawa azilandira chithandizo cha mafoni cha 6GHz, **zomwe zingathandize kukula kwachangu kwa zipangizo za 6GHz.**
Ma wailesi owonera ndi chida chofunikira kwambiri. Chifukwa cha kupita patsogolo kwa kulumikizana kwa mafoni, kusowa kwa wailesi owonera kwakhala kofala kwambiri m'zaka zaposachedwa. Mayiko ambiri amaika patsogolo kwambiri kugawa kwa zida zapakati pa band. **Band ya 6GHz, yokhala ndi 700MHz ~ 1200MHz ya bandwidth yopitilira yapakati pa band, ndiye band yabwino kwambiri yolumikizirana ndi mphamvu zambiri m'dera lonselo. Kumayambiriro kwa mwezi wa Meyi chaka chino, Unduna wa Zachuma ndi Ukadaulo wa Chidziwitso ku China unafalitsa Malamulo Okhudza Kugawa Mafunde a Mawayilesi ku China, omwe akutsogolera padziko lonse lapansi pakugawa band ya 6GHz ya machitidwe a IMT ndikupereka zida zokwanira zamafupipafupi apakati pa chitukuko cha 5G/6G.**
Chifukwa chake, **Wang Xiaolu, mtsogoleri wa gulu la anthu aku China la WRC-23 Agenda Item 9.1C, anati**: "Kugwiritsa ntchito ukadaulo wa IMT m'mabande okhazikika a ma frequency a broadband opanda zingwe kungapangitse kuti ntchito ya IMT ipitirire patsogolo. Izi zithandiza kuti IMT ikhale ndi malo ambiri okhala ndi chuma chambiri, kulimbikitsa kugwiritsa ntchito bwino zinthu za wailesi, kutsogolera kukula kwa makampani a IMT padziko lonse lapansi."
Ndipotu, GSMA idapereka lipoti la zamoyo pa gulu la 6GHz la IMT chaka chatha kutengera kafukufuku wozama wa ogwira ntchito akuluakulu padziko lonse lapansi, opanga zida, ogulitsa ma chip ndi makampani a RF m'makampani onse ogulitsa zinthu. **Lipotilo likuwonetsa chiyembekezo chachikulu mkati mwa makampani onse pa gulu la 6GHz. Ogwira ntchito otsogola padziko lonse lapansi ndi anthu ena ofufuza onse amakhulupirira kuti gulu la 6GHz ndilofunika kwambiri kuti maukonde apitirire kupita patsogolo.**
Poganizira za chitukuko cha 5G padziko lonse lapansi, **ma mid-band monga 2.6GHz, 3.5GHz onse ndi ma frequency odziwika bwino. Popeza 5G ikukula mwachangu komanso kukula, kusintha ndi kusinthasintha kwa ukadaulo wa 5.5G ndi 6G kudzachitika.** Ndi kufalikira ndi mphamvu zamphamvu, 6GHz band ithandiza kumanga ma netiweki apamwamba olumikizirana ndi mafoni. **Miyezo ya 5G-A ndi 6G yaphatikizidwa kale mu miyezo ya 3GPP pasadakhale, zomwe zimapangitsa kuti makampani agwirizane pa njira yaukadaulo.** Kukhwima kwa miyezo ya 5G-A kudzayambitsa kafukufuku ndi chitukuko m'makampani onse a 5G-A, komanso kupereka mwayi wofunikira pakulankhulana kwa mafoni a 6G.
**Pamsonkhanowu, oyang'anira adagwirizana kuti aphunzire kugawa gulu la 7-8.5GHz la 6G panthawi yake pamsonkhano wotsatira wa ITU mu 2027.** Izi zikugwirizana ndi malingaliro a Ericsson ndi ena okhudza ntchito zoyambirira za 6G pakati pa 7GHz ndi 20GHz. Bungwe la Global Mobile Suppliers Association (GSA) linanena mu lipoti lake kuti: **"Mgwirizanowu wapadziko lonse lapansi ukuteteza kukula kwa 5G padziko lonse lapansi ndipo ukutsegulira njira 6G kupitirira 2030."** Ntchito yaukadaulo yayamba kale pakutsimikizira kugawana ndi kugwirizana pakati pa 6G spectrum yodziwika ndi kagwiritsidwe ntchito komwe kulipo.
Wapampando wa FCC, Jessica Rosenworcel, adapereka ndemanga pa ntchito ya WRC-23: "WRC-23 si ntchito ya milungu ingapo yokha ku Dubai. Ikuyimiranso zaka zambiri zokonzekera ndi ogwira ntchito ku FCC, akatswiri aboma, ndi mafakitale. Zomwe gulu lathu lachita zidzapititsa patsogolo luso lamakono mu ma spectrum opanda zilolezo, kuphatikizapo Wi-Fi, kuthandizira kulumikizana kwa 5G, ndikutsegulira njira ya 6G."
Concept Microwave ndi kampani yopanga zinthu za 5G RF ku China, kuphatikizapo fyuluta ya RF lowpass, fyuluta ya highpass, fyuluta ya bandpass, fyuluta ya notch/band stop, duplexer, Power divider ndi directional coupler. Zonsezi zitha kusinthidwa malinga ndi zomwe mukufuna.
