Ingqungquthela Yomhlaba Yezokuxhumana Ngomsakazo ka-2023 (WRC-23), eyathatha amasonto amaningana, yaphetha eDubai ngomhlaka-15 Disemba ngesikhathi sendawo. I-WRC-23 ixoxe futhi yenza izinqumo mayelana nezihloko eziningana ezishisayo njengebhendi ye-6GHz, amasathelayithi, kanye nobuchwepheshe be-6G. Lezi zinqumo zizobumba ikusasa lokuxhumana ngeselula. **I-International Telecommunication Union (ITU) ithe amazwe angamalungu ayi-151 asayine idokhumenti yokugcina ye-WRC-23.***
Ingqungquthela ithole i-spectrum entsha ye-IMT ye-4G, 5G kanye ne-6G yesikhathi esizayo okuyinto ebalulekile. Ibhendi entsha yemvamisa - ibhendi ye-6GHz (6.425-7.125GHz) yabelwe ukuxhumana kweselula ezifundeni ze-ITU (Europe, Middle East kanye ne-Afrika, Americas, Asia-Pacific). Lokhu kuvumela ukumbozwa kweselula kwe-6GHz okuhlangene kwezigidigidi zabantu kulezi zifunda, **okuzokwenza kube lula ukukhula okusheshayo kwesistimu yedivayisi ye-6GHz.**
I-radio spectrum iyisisetshenziswa esibalulekile samasu. Ngokuthuthuka kokuxhumana kweselula, ukuntuleka kwe-radio spectrum kuye kwaba sobala kakhulu eminyakeni yamuva. Amazwe amaningi abheka ukubaluleka okukhulu ekwabiweni kwezinsizakusebenza ze-mid-band spectrum. **Ibhendi engu-6GHz, ene-bandwidth ye-700MHz ~ 1200MHz eqhubekayo ye-mid-band spectrum, iyibhendi yemvamisa efanelekile yokunikeza ukuxhumana okunamandla aphezulu endaweni ebanzi. Ekuqaleni kukaMeyi kulo nyaka, uMnyango Wezimboni Nobuchwepheshe Bolwazi waseShayina washicilela iMithethonqubo Yokwabiwa Kwemvamisa Yomsakazo waseShayina, ehola umhlaba wonke ekwabeni ibhendi engu-6GHz yezinhlelo ze-IMT kanye nokuhlinzeka ngezinsizakusebenza ezanele zemvamisa ye-mid-band yokuthuthukiswa kwe-5G/6G.**
Ngakho-ke, uWang Xiaolu, inhloko yethimba laseShayina le-WRC-23 Agenda Item 9.1C, uthe**: “Ukusebenzisa ubuchwepheshe be-IMT kuma-frequency band asevisi aqinile we-broadband engenantambo engaguquki kungandisa kakhulu izimo zohlelo lokusebenza lwe-IMT. Lokhu kuzokwenza kube lula uhlelo lwe-IMT olubanzi kakhulu olunezomnotho, kukhuthaze ukusetshenziswa okunengqondo nokusebenza kahle kwezinsizakusebenza ze-radio spectrum, kuqondise ukukhula kwemboni ye-IMT yomhlaba wonke esezingeni eliphezulu.”
Eqinisweni, i-GSMA ikhiphe umbiko we-ecosystem ngebhendi ye-6GHz ye-IMT ngonyaka odlule ngokusekelwe ocwaningweni oluningiliziwe ngabaqhubi abakhulu bomhlaba wonke, abakhiqizi bamadivayisi, abathengisi bama-chip kanye nezinkampani ze-RF kulo lonke uchungechunge lwenani lomkhakha. **Umbiko ukhombisa ukulindela okukhulu kulo lonke imboni maqondana nebhendi ye-6GHz. Abaqhubi abahamba phambili emhlabeni wonke kanye nezinye izifundo zocwaningo bonke bakholelwa ukuthi ibhendi ye-6GHz ibaluleke kakhulu ekuthuthukisweni kwenethiwekhi okuqhubekayo.**
Uma sibheka intuthuko yomhlaba wonke ye-5G, **ama-mid-band afana ne-2.6GHz, 3.5GHz wonke amaza ajwayelekile. Njengoba i-5G ikhula ngokushesha futhi ikhula ngokuvuthwa, kuzokwenzeka ukushintshela nokubuyela emuva kubuchwepheshe be-5.5G kanye ne-6G.** Ngokumbozwa kanye namandla omthamo, i-6GHz band izokwenza kube lula ukwakhiwa kwamanethiwekhi okuxhumana kwamaselula asezingeni eliphezulu. **Izindinganiso ze-5G-A kanye ne-6G sezivele zifakiwe ezindinganisweni ze-3GPP kusengaphambili, okwakha ukuvumelana kwemboni ngomzila wezobuchwepheshe.** Ukukhula kwezindinganiso ze-5G-A kuzothuthukisa i-R&D kuyo yonke imboni ye-5G-A, futhi kuveze namathuba abalulekile ezokuxhumana kweselula ze-6G.
**Ngesikhathi sengqungquthela, abalawuli bavumile ukufunda ukwabela ibhendi engu-7-8.5GHz ye-6G ngesikhathi esifanele engqungqutheleni elandelayo ye-ITU ngo-2027.** Lokhu kuhambisana neziphakamiso ze-Ericsson nezinye zemisebenzi yokuqala ye-6G phakathi kwe-7GHz kuya ku-20GHz. I-Global Mobile Suppliers Association (GSA) isho esitatimendeni sabezindaba: **“Lesi sivumelwano somhlaba wonke siqinisekisa ukukhula okuqhubekayo kwe-5G emhlabeni jikelele futhi sivula indlela ye-6G ngale kuka-2030.”** Umsebenzi wobuchwepheshe usuqalile kakade ekuqinisekiseni ukwabelana kanye nokuhambisana phakathi kwe-spectrum ye-6G ehlonziwe kanye nokusetshenziswa okukhona.
USihlalo we-FCC uJessica Rosenworcel uphawule ngomsebenzi we-WRC-23: “I-WRC-23 akuyona nje imisebenzi yamasonto ambalwa eDubai. Iphinde imele iminyaka yokulungiselela kwabasebenzi be-FCC, ochwepheshe bakahulumeni, kanye nemboni. Impumelelo yethimba lethu izothuthukisa ukusungula izinto ezintsha ku-spectrum engenalayisensi, okuhlanganisa i-Wi-Fi, isekele ukuxhumana kwe-5G, futhi ivule indlela ye-6G.”
I-Concept Microwave ingumkhiqizi ochwepheshe wezingxenye ze-5G RF eShayina, okuhlanganisa isihlungi se-RF lowpass, isihlungi se-highpass, isihlungi se-bandpass, isihlungi se-notch/band stop, i-duplexer, i-Power divider kanye ne-directional coupler. Zonke zingenziwa ngokwezifiso ngokwezidingo zakho.
