INgqungquthela yeHlabathi yoNxibelelwano ngeRadio ka-2023 (i-WRC-23), ethathe iiveki ezininzi, igqitywe eDubai nge-15 kaDisemba ngexesha lendawo. I-WRC-23 ixoxe kwaye yenza izigqibo malunga nezihloko ezininzi ezishushu ezifana nebhendi ye-6GHz, iisathelayithi, kunye netekhnoloji ye-6G. Ezi zigqibo ziya kuyila ikamva lonxibelelwano oluphathwayo. **I-International Telecommunication Union (i-ITU) ithe amazwe angamalungu ali-151 atyikitye uxwebhu lokugqibela lwe-WRC-23.**
Le ngqungquthela ichonge i-spectrum entsha ye-IMT ye-4G, 5G kunye ne-6G yexesha elizayo ebalulekileyo. Ibhendi entsha yefrikhwensi – ibhendi ye-6GHz (6.425-7.125GHz) yabelwe unxibelelwano lweselula kwimimandla ye-ITU (iYurophu, uMbindi Mpuma kunye ne-Afrika, iMelika, i-Asia-Pacific). Oku kuvumela ukugubungela okudibeneyo kwe-6GHz yeselula kwiibhiliyoni zabemi kulo lonke eli candelo, **okuya kunceda ngokuthe ngqo ukukhula ngokukhawuleza kwenkqubo yesixhobo se-6GHz.**
I-radio spectrum sisixhobo esibalulekileyo esibalulekileyo. Ngenxa yokuqhubela phambili konxibelelwano lweselula, ukunqongophala kwe-radio spectrum kuye kwanda kakhulu kwiminyaka yakutshanje. Amazwe amaninzi abeka ukubaluleka okukhulu ekwabiweni kwezixhobo ze-mid-band spectrum. **Ibhendi ye-6GHz, ene-700MHz ~ 1200MHz ye-mid-band bandwidth eqhubekayo, yeyona bhendi yefrikhwensi efanelekileyo yokubonelela ngoqhagamshelo oluphezulu kwindawo ebanzi. Ngaphambili ngoMeyi kulo nyaka, uMphathiswa wezoShishino kunye neTekhnoloji yoLwazi waseTshayina wapapasha iMithetho yoKwabiwa kweeFrekhi zeRadio yaseTshayina, ethatha ukhokelo lwehlabathi ekwabeni ibhendi ye-6GHz kwiinkqubo ze-IMT kunye nokubonelela ngezixhobo ezaneleyo zefrikhwensi ye-mid-band yophuhliso lwe-5G/6G.**
Ngenxa yoko, **UWang Xiaolu, intloko yegqiza laseTshayina kwi-WRC-23 Agenda Item 9.1C, uthe**: “Ukusebenzisa ubuchwepheshe be-IMT kwiibhendi ze-frequency zenkonzo esisigxina kwi-broadband engenazingcingo esisigxina kunokwandisa ngakumbi iimeko zesicelo se-IMT. Oku kuya kwenza kube lula inkqubo ye-IMT ebanzi ngakumbi enoqoqosho olukhulu, ikhuthaza ukusetyenziswa okunengqiqo nokusebenzayo kwezixhobo ze-radio spectrum, ikhokela ukukhula kweshishini le-IMT elisemgangathweni ophezulu.”
Enyanisweni, i-GSMA ikhuphe ingxelo ye-ecosystem kwibhendi ye-6GHz ye-IMT kunyaka ophelileyo ngokusekelwe kuphando oluneenkcukacha ngabaqhubi abakhulu behlabathi, abavelisi bezixhobo, abathengisi beetships kunye neenkampani ze-RF kulo lonke uthotho lwexabiso loshishino. **Le ngxelo ibonisa ulindelo olukhulu kulo lonke ishishini kwibhendi ye-6GHz. Abaqhubi abaphambili kwihlabathi kunye nabanye abaphandi bonke bakholelwa ukuba ibhendi ye-6GHz ibaluleke kakhulu ekuqhubekeni nophuhliso lwenethiwekhi.**
Xa sijonga uphuhliso lwe-5G lwehlabathi, **iibhendi eziphakathi ezifana ne-2.6GHz, 3.5GHz zonke ziifrikhwensi eziqhelekileyo. Njengoko i-5G ikhula ngokukhawuleza kwaye ikhula ngokukhawuleza, utshintsho kunye nokubuyela kwiteknoloji ye-5.5G kunye ne-6G kuya kwenzeka.** Ngokugubungela kunye namandla omthamo, ibhendi ye-6GHz iya kunceda ukwakhiwa kweenethiwekhi zonxibelelwano lweselula ezikumgangatho ophezulu. **Imigangatho ye-5G-A kunye ne-6G sele ifakiwe kwimigangatho ye-3GPP kwangaphambili, nto leyo eyenza ukuvumelana kweshishini malunga nendlela yobuchwepheshe.** Ukukhula kwemigangatho ye-5G-A kuya kukhuthaza uR&D kulo lonke ishishini le-5G-A, kwaye kunike namathuba axabisekileyo kunxibelelwano lweselula lwe-6G.
**Ngexesha lenkomfa, abalawuli bavumile ukufunda ukwabela ibhendi ye-7-8.5GHz ye-6G ngexesha elifanelekileyo kwinkomfa elandelayo ye-ITU ngo-2027.** Oku kuhambelana neziphakamiso ze-Ericsson kunye nezinye zeenkqubo zokuqala ze-6G phakathi kwe-7GHz ukuya kwi-20GHz. I-Global Mobile Suppliers Association (GSA) yathi kwingxelo yabezindaba: **“Esi sivumelwano sehlabathi siqinisekisa ukukhula okuqhubekayo kwe-5G kwihlabathi liphela kwaye sivula indlela ye-6G ngaphaya kowama-2030.”** Umsebenzi wobugcisa sele uqalile ekuqinisekiseni ukwabelana kunye nokuhambelana phakathi kwe-spectrum ye-6G echongiweyo kunye nokusetyenziswa okukhoyo.
USihlalo we-FCC uJessica Rosenworcel uthethe ngomsebenzi we-WRC-23 wathi: “I-WRC-23 ayisiyonto nje yeeveki ezimbalwa zomsebenzi eDubai. Ikwamele iminyaka yokulungiselela ngabasebenzi be-FCC, iingcali zikarhulumente, kunye noshishino. Impumelelo yegqiza lethu iya kuphucula ubuchule kwi-spectrum engenalayisenisi, kubandakanya i-Wi-Fi, ixhase uqhagamshelo lwe-5G, kwaye ivule indlela ye-6G.”
I-Concept Microwave ngumvelisi ochwephesha wezixhobo ze-5G RF eTshayina, kuquka isihluzo se-RF lowpass, isihluzo se-highpass, isihluzo se-bandpass, isihluzo se-notch/i-band stop, i-duplexer, i-Power divider kunye ne-directional coupler. Zonke zingenziwa ngokwezifiso ngokweemfuno zakho.
