Musangano weWorld Radiocommunication Conference 2023 (WRC-23), wakatora mavhiki akati wandei, wakapera muDubai musi wa15 Zvita panguva yeko. WRC-23 yakakurukura nekuita sarudzo maererano nenyaya dzinoverengeka dzinopisa dzakadai sebhendi re6GHz, masateliti, uye matekinoroji e6G. Sarudzo idzi dzichaumba ramangwana rekutaurirana nefoni. **International Telecommunication Union (ITU) yakati nyika dziri nhengo zana nemakumi mashanu neimwe dzakasaina gwaro rekupedzisira reWRC-23.***
Musangano uyu wakawana nzira itsva yeIMT ye4G, 5G uye 6G yeramangwana iyo yakakosha. Bhandi idzva rema frequency - 6GHz band (6.425-7.125GHz) rakagoverwa kutaurirana nefoni munzvimbo dzeITU (Europe, Middle East & Africa, Americas, Asia-Pacific). Izvi zvinogonesa kubatana kwe6GHz mobile coverage kumabhiriyoni evanhu munzvimbo idzi, **izvo zvichabatsira zvakananga kukura nekukurumidza kwemidziyo ye6GHz.**
Radio spectrum chinhu chakakosha pakugadzirisa nyaya. Nekufambira mberi kwekutaurirana nefoni, kushomeka kweradio spectrum kwave kuchiwedzera kuonekwa mumakore achangopfuura. Nyika zhinji dzinokoshesa zvikuru kugoverwa kwezviwanikwa zve mid-band spectrum. **Band ye6GHz, ine 700MHz ~ 1200MHz ye mid-band spectrum bandwidth inoramba iripo, ndiyo frequency band yakakodzera kupa connection yakakura munzvimbo yakakura. Pakutanga kwaChivabvu gore rino, Ministry of Industry and Information Technology yeChina yakaburitsa Regulations on Radio Frequency Allocation of China, ichitungamira pasi rose mukupa 6GHz band yeIMT systems uye kupa zviwanikwa zvakawanda zve mid-band frequency zvekuvandudza 5G/6G.**
Saka, **Wang Xiaolu, mukuru weboka reChinese reWRC-23 Agenda Item 9.1C, akati**: "Kushandisa matekinoroji eIMT mumabhendi ebasa rakagadziriswa kune fixed wireless broadband kunogona kuwedzera mamiriro ekushandiswa kweIMT. Izvi zvichaita kuti IMT ive nehupfumi hwakawanda, zvichikurudzira kushandiswa kwezviwanikwa zveredhiyo zvine musoro uye zvinobudirira, zvichitungamira kukura kweindasitiri yeIMT yepasi rose."
Kutaura zvazviri, GSMA yakaburitsa mushumo we ecosystem pabhendi re6GHz reIMT gore rapera zvichibva pakutsvagurudza kwakadzama kwakaitwa nevanoita mabasa makuru pasi rose, vagadziri vemidziyo, vatengesi vemachipisi uye makambani eRF muchikamu chevalue cheindasitiri. **Mushumo uyu unoratidza tarisiro huru mukati meindasitiri yese yebhendi re6GHz. Vanoita mabasa makuru pasi rose nevamwe vanhu vanoongorora vanotenda kuti bhendi re6GHz rakakosha zvikuru kuti network irambe ichifambira mberi.**
Tichitarisa kukura kwe5G pasi rose, **mabhendi epakati akadai se2.6GHz, 3.5GHz ese ari mafrequency makuru. Sezvo 5G ichikura nekukurumidza uye kukura kuri kuwedzera, shanduko uye kufambira mberi kune matekinoroji e5.5G ne6G kuchaitika.** Nekufukidza uye kugona kwayo, bhendi re6GHz richaita kuti pave nekuvaka network dzekukurukurirana dzemhando yepamusoro. **5G-A ne6G zviyero zvakatobatanidzwa mu3GPP zviyero pachine nguva, zvichigadzira kubvumirana kweindasitiri pane nzira yetekinoroji.** Kukura kwe5G-A zviyero kuchakurudzira R&D muindasitiri yese ye5G-A, uye zvakare kuchapa mikana yakakosha yekutaurirana kwe6G nenharembozha.
**Panguva yemusangano, vatongi vakabvumirana kudzidza kugovera bhendi re7-8.5GHz re6G nenguva yakakodzera pamusangano unotevera weITU muna 2027.** Izvi zvinoenderana nepfungwa dzaEricsson nedzimwe dzekushanda kwekutanga kwe6G pakati pe7GHz kusvika 20GHz. Sangano reGlobal Mobile Suppliers Association (GSA) rakataura mupepanhau kuti: **"Chibvumirano ichi chepasi rose chinochengetedza kukura kwe5G pasi rose uye chinovhura nzira ye6G kupfuura 2030."** Basa rehunyanzvi rakatotanga pakuona kugovaniswa uye kuenderana pakati pe6G spectrum yakawanikwa nekushandiswa kuripo.
Sachigaro weFCC, Jessica Rosenworcel, akataura nezvebasa reWRC-23 achiti: “WRC-23 haisiri basa remavhiki mashoma chete muDubai. Inomiririrawo makore ekugadzirira kwevashandi veFCC, nyanzvi dzehurumende, uye maindasitiri. Zvakaitwa nevashandi vedu zvichasimudzira hunyanzvi muzvinhu zvisina marezenisi, kusanganisira Wi-Fi, kutsigira kubatana kwe5G, uye kugadzira nzira ye6G.”
Concept Microwave inyanzvi yekugadzira zvikamu zve5G RF muChina, zvinosanganisira RF lowpass filter, highpass filter, bandpass filter, notch filter/band stop filter, duplexer, Power divider uye directional coupler. Zvese zvinogona kugadziriswa zvichienderana nezvaunoda.
