I-World Radiocommunication Conference 2023 (WRC-23), ethathe amasonto ambalwa, yaphothulwa eDubai ngoDisemba 15 ngesikhathi sasekhaya.I-WRC-23 ixoxe futhi yenza izinqumo mayelana nezihloko ezimbalwa ezishisayo njengebhendi ye-6GHz, amasathelayithi, nobuchwepheshe be-6G.Lezi zinqumo zizololonga ikusasa lezokuxhumana ngomakhalekhukhwini.**I-International Telecommunication Union (ITU) ithe amazwe angamalungu angu-151 asayine umqulu wokugcina we-WRC-23.**
Ingqungquthela ihlonze i-spectrum ye-IMT entsha ye-4G, 5G kanye ne-6G yesikhathi esizayo okuyinto ebalulekile.Ibhendi entsha yefrikhwensi - ibhendi engu-6GHz (6.425-7.125GHz) yabelwe ukuxhumana kweselula ezifundeni ze-ITU (i-Europe, Middle East & Africa, Americas, Asia-Pacific).Lokhu kunika amandla ukufakwa okuhlanganisiwe kweselula kwe-6GHz izigidigidi zabantu kuzo zonke lezi zifunda, **okuzosiza ngokuqondile ukukhula okusheshayo kwe-ecosystem yedivayisi engu-6GHz.**
I-radio spectrum iyinsiza ebalulekile yamasu.Ngokuthuthuka kwezokuxhumana ngomakhalekhukhwini, ukushoda kwe-radio spectrum kuye kwagqama kakhulu eminyakeni yamuva nje.Amazwe amaningi abheka ukubaluleka okukhulu ekwabiweni kwezinsiza ze-middle-band spectrum.**Ibhendi engu-6GHz, eno-700MHz~1200MHz womkhawulokudonsa oqhubekayo we-mid-band spectrum, iyibhendi yefrikhwensi yekhandidethi efanelekile ukuletha uxhumo lwendawo ebanzi lwekhono eliphezulu.Ngasekuqaleni kukaMeyi kulo nyaka, uMnyango Wezimboni Nobuchwepheshe Bolwazi wase-China ushicilele Imithetho Emayelana Nokwabiwa Kwemisakazo YaseShayina, ehamba phambili emhlabeni wonke ekwabeni ibhendi ye-6GHz yezinhlelo ze-IMT nokuhlinzeka ngezinsiza ezanele zamafrikhwensi e-mid-band ukuze kuthuthukiswe i-5G/6G.* *
Ngakho-ke, **u-Wang Xiaolu, inhloko yethimba laseShayina le-WRC-23 Agenda Item 9.1C, uthe**: “Ukusebenzisa ubuchwepheshe be-IMT kumabhendi efrikhwensi yesevisi engaguquki obubanzi obungenantambo kungaqhubeka nokwandisa izimo zohlelo lwe-IMT.Lokhu kuzokwenza kube lula uhlelo olubanzi lwe-IMT lwe-ecosystem enomnotho wezinga, ukukhuthaza ukusetshenziswa okuphusile nokusebenza kahle kwezinsiza ze-spectrum yomsakazo, okuqondisa ukukhula kwemboni ye-IMT okusezingeni eliphezulu emhlabeni jikelele.”
Eqinisweni, i-GSMA ikhiphe umbiko we-ecosystem ngebhendi ye-IMT engu-6GHz ngonyaka odlule ngokusekelwe ocwaningweni oluningiliziwe ngama-opharetha amakhulu omhlaba, abakhiqizi bemishini, abathengisi bama-chip nezinkampani ze-RF kulo lonke uchungechunge lwenani lemboni.**Umbiko ukhombisa okulindelwe okuphezulu kuyo yonke imboni mayelana nebhendi ye-6GHz.Ama-opharetha ahamba phambili emhlabeni wonke nezinye izihloko zocwaningo zonke zikholelwa ukuthi ibhendi ye-6GHz ibaluleke kakhulu ekuthuthukisweni kwenethiwekhi okuqhubekayo.**
Uma sibheka ukuthuthukiswa kwe-5G yomhlaba wonke, **amabhendi amaphakathi afana ne-2.6GHz, 3.5GHz wonke amaza ajwayelekile.Njengoba i-5G ijabulela ukukhula okusheshayo nokukhula okukhulayo, ukuguquka nokuphindaphinda ukuya kubuchwepheshe be-5.5G kanye ne-6G kuzokwenzeka.** Ngokuhlanganisa namandla omthamo, ibhendi ye-6GHz izokwenza lula ukwakhiwa kwamanethiwekhi okuxhumana amaselula ekhwalithi ephezulu.**Amazinga e-5G-A kanye ne-6G asevele efakwe ezindinganisweni ze-3GPP kusenesikhathi, okwenza ukuvumelana kwemboni ngomgudu wobuchwepheshe.** Ukuvuthwa kwamazinga e-5G-A kuzothuthukisa i-R&D kuyo yonke imboni ye-5G-A, futhi kuveze namathuba abalulekile e-6G. ezokuxhumana ngomakhalekhukhwini.
**Phakathi nenkomfa, abalawuli bavumile ukutadisha ukwaba ibhendi ye-7-8.5GHz ku-6G ngesikhathi engqungqutheleni elandelayo ye-ITU ngo-2027.** Lokhu kuhambisana neziphakamiso zika-Ericscal nezinye zemisebenzi yangaphambi kwesikhathi ye-6G phakathi kuka-7GHz kuya ku-20GHz.I-Global Mobile Suppliers Association (GSA) yathi esitatimendeni sabezindaba: **“Lesi sivumelwano somhlaba wonke sivikela ukukhula okuqhubekayo kwe-5G emhlabeni jikelele futhi sivula indlela ye-6G ngale kuka-2030.”** Umsebenzi wezobuchwepheshe usuqalile kakade ukuze kutholakale ukwabelana nokuhambisana phakathi ikhombe i-spectrum ye-6G kanye nokusetshenziswa okukhona.
USihlalo we-FCC u-Jessica Rosenworcel uphawule ngomsebenzi we-WRC-23: “I-WRC-23 akuwona nje amaviki ambalwa omsebenzi e-Dubai.Iphinde imele iminyaka yokulungiselela ngabasebenzi be-FCC, ochwepheshe bakahulumeni, nezimboni.Okufezwe yithimba lethu kuzothuthukisa ukuqanjwa okusha ku-spectrum engagunyaziwe, okuhlanganisa i-Wi-Fi, ukusekela uxhumano lwe-5G, futhi kuvule indlela ye-6G. "
I-Concept Microwave ingumkhiqizi ochwepheshile wezingxenye ze-5G RF e-China, okuhlanganisa isihlungi se-RF lowpass, isihlungi se-highpass, isihlungi se-bandpass, isihlungi se-notch/i-band stop filter, i-duplexer, isihlukanisi samandla kanye ne-coupler eqondisayo.Zonke zingenziwa ngezifiso ngokuya ngezidingo zakho.
