Msonkhano wapadziko lonse wa Radiocommunication Conference 2023 (WRC-23), womwe umatenga milungu ingapo, udatha ku Dubai pa Disembala 15 nthawi yakomweko. WRC-23 idakambirana ndikupanga zisankho pamitu ingapo yotentha ngati gulu la 6GHz, ma satellite, ndi matekinoloje a 6G. Zosankhazi zidzasintha tsogolo la mauthenga a m'manja. **Bungwe la International Telecommunication Union (ITU) linanena kuti mayiko 151 omwe ali mamembala asayina chikalata chomaliza cha WRC-23.**
Msonkhanowu udazindikira mawonekedwe atsopano a IMT a 4G, 5G ndi 6G yamtsogolo zomwe ndizofunikira. Gulu latsopano la ma frequency - 6GHz band (6.425-7.125GHz) linaperekedwa kuti lizilumikizana ndi mafoni m'madera a ITU (Europe, Middle East & Africa, Americas, Asia-Pacific). Izi zimathandizira kuti anthu mabiliyoni ambiri azitha kulumikizana ndi 6GHz m'magawo awa, **zomwe zithandizira kukula kwachangu kwa chipangizo cha 6GHz.**
Mawayilesi sipekitiramu ndi yofunika njira gwero. Chifukwa cha kupita patsogolo kwa njira zolumikizirana ndi mafoni, kuchepa kwa ma wayilesi kwachulukirachulukira m'zaka zaposachedwa. Mayiko ambiri amawona kufunikira kwakukulu pakugawa chuma chapakati pamagulu apakati. **Bandi ya 6GHz, yokhala ndi 700MHz ~ 1200MHz ya bandiwidth yopitilira yapakati ya bandi, ndiye gulu labwino kwambiri la ma frequency omwe amalumikizana ndi malo ambiri. Kumayambiriro kwa mwezi wa Meyi chaka chino, Unduna wa Zamakampani ndi Ukadaulo Wachidziwitso ku China udafalitsa Regulations on Radio Frequency Allocation of China, yomwe idatsogola padziko lonse lapansi pakugawira gulu la 6GHz pamakina a IMT komanso kupereka zida zokwanira zapakati pa band kuti zithandizire chitukuko cha 5G/6G.**
Chifukwa chake, **Wang Xiaolu, wamkulu wa nthumwi zaku China za WRC-23 Agenda Item 9.1C, adati**: "Kugwiritsa ntchito matekinoloje a IMT pama bandi okhazikika amtundu wa ma frequency amtundu wa waya kungathe kukulitsa zochitika za IMT. kukula kwamakampani a IMT padziko lonse lapansi. ”
M'malo mwake, GSMA idapereka lipoti la chilengedwe pa bandi ya 6GHz ya IMT chaka chatha kutengera kafukufuku watsatanetsatane wamakampani akuluakulu padziko lonse lapansi, opanga zida, ogulitsa ma chips ndi makampani a RF pagulu lazamalonda. ** Lipotilo likuwonetsa chiyembekezo chachikulu mumakampani onse kupita ku gulu la 6GHz. Otsogolera padziko lonse lapansi ndi maphunziro ena ofufuza onse amakhulupirira kuti gulu la 6GHz ndilofunika kwambiri kuti maukonde apitirire patsogolo.**
Kuyang'ana chitukuko cha 5G padziko lonse lapansi, **magulu apakati ngati 2.6GHz, 3.5GHz onse ndi ma frequency ambiri. Pamene 5G ikusangalala ndi kukula kofulumira komanso kukula, kusintha ndi kubwereza kwa teknoloji ya 5.5G ndi 6G kudzachitika.* * Pogwiritsa ntchito chidziwitso ndi mphamvu zamphamvu, gulu la 6GHz lidzathandizira kumanga maukonde apamwamba olankhulana ndi ma cellular. **Miyezo ya 5G-A ndi 6G yakhala ikuphatikizidwa kale muzotsatira za 3GPP pasadakhale, kupanga mgwirizano wamakampani pamayendedwe aukadaulo.* * Miyezo yokhwima ya 5G-A idzathandizira R&D pamakampani onse a 5G-A, komanso ikupereka mwayi wofunika kwambiri wamalumikizidwe amafoni a 6G.
**Pamsonkhanowu, owongolera adagwirizana kuti aphunzire kugawa gulu la 7-8.5GHz la 6G munthawi yake pamsonkhano wotsatira wa ITU mu 2027.** Izi zikugwirizana ndi malingaliro a Ericsson ndi ena oyambira 6G oyambira pakati pa 7GHz mpaka 20GHz. Bungwe la Global mobile Suppliers Association (GSA) linanena m'mawu atolankhani kuti: **“Mgwirizano wapadziko lonse uwu umapangitsa kuti 5G ipitirirebe kukula padziko lonse lapansi ndikutsegulira njira ya 6G kupitirira 2030.”** Ntchito yaukadaulo yayamba kale kutsimikizira kugawana ndi kugwirizana pakati pa mawonekedwe a 6G odziwika ndi omwe alipo.
Wapampando wa FCC a Jessica Rosenworcel adathirira ndemanga pa ntchito ya WRC-23: "WRC-23 si ntchito ya milungu ingapo ku Dubai, ikuyimiranso zaka zokonzekera za ogwira ntchito ku FCC, akatswiri a boma, ndi mafakitale.
Concept Microwave ndi katswiri wopanga zida za 5G RF ku China, kuphatikiza fyuluta ya RF lowpass, fyuluta ya highpass, fyuluta ya bandpass, fyuluta ya notch/band stop fyuluta, duplexer, Power divider ndi directional coupler. Zonsezi zitha kusinthidwa malinga ndi zomwe mukufuna.
