Kugoverwa kwe6GHz Spectrum Yakapedzwa
Iyo WRC-23 (World Radiocommunication Conference 2023) ichangobva kupera muDubai, yakarongwa neInternational Telecommunication Union (ITU), ine chinangwa chekubatanidza kushandiswa kwepasi rose.
Huridzi hweiyo 6GHz spectrum ndiyo yaive nzvimbo yekutarisisa yepasirese.
Musangano wakasarudza: Kugovera iyo 6.425-7.125GHz bhendi (700MHz bandwidth) yemasevhisi enhare, kunyanya ye5G nharembozha.
Chii chinonzi 6GHz?
6GHz inoreva spectrum renji kubva pa5.925GHz kusvika 7.125GHz, ine bandwidth inosvika 1.2GHz. Pakutanga, iyo yakagoverwa yepakati-kusvika-yakaderera frequency spectra yenharembozha yakange yatove nekushandiswa kwakatsaurirwa, nekungoshandiswa kwe6GHz spectrum kusara kusingazivikanwe. Yekutanga yakatsanangurwa yekumusoro muganho we Sub-6GHz ye5G yaive 6GHz, pamusoro iyo iri mmWave. Neiyo inotarisirwa 5G lifecycle yekuwedzera uye yakashata kutengeserana tarisiro yemmWave, zviri pamutemo kubatanidza 6GHz kwakakosha kune 5G inotevera chikamu chebudiriro.
3GPP yakatomisikidza hafu yepamusoro ye6GHz, kunyanya 6.425-7.125MHz kana 700MHz, muRelease 17, inozivikanwawo seU6G ine frequency bhendi zita n104.
Wi-Fi yanga ichirwirawo 6GHz. NeWi-Fi 6E, 6GHz yakaverengerwa muyero. Sezvinoratidzwa pazasi, ne6GHz, mabhendi eWi-Fi achakura kubva pa600MHz mu2.4GHz uye 5GHz kusvika 1.8GHz, uye 6GHz ichatsigira kusvika ku320MHz bandwidth kune imwe chete inotakura muWi-Fi.
Zvinoenderana neshumo neWi-Fi Alliance, Wi-Fi parizvino inopa yakawanda network network, ichiita 6GHz ramangwana reWi-Fi. Izvo zvinodikanwa kubva kunharembozha ye6GHz hazvina musoro sezvo yakawanda spectrum inoramba isingashandiswe.
Mumakore achangopfuura, pave neatatu maonero pane iyo 6GHz varidzi: Kutanga, igovere zvizere kuWi-Fi. Chechipiri, igovere zvizere kune nharembozha (5G). Chechitatu, patsanura zvakaenzana pakati pezviviri.
Sezvinoonekwa pawebhusaiti yeWi-Fi Alliance, nyika dzemuAmerica dzakanyanya kugovera iyo 6GHz yese kuWi-Fi, nepo Europe inorerekera pakugovera chikamu chezasi kuWi-Fi. Sezvingatarisirwa, chikamu chepamusoro chakasara chinoenda ku5G.
Sarudzo yeWRC-23 inogona kutariswa sesimbiso yekubvumirana kwakagadzwa, kuwana kuhwina-kuhwina pakati pe5G neWi-Fi kuburikidza nemakwikwi epakati uye kuregeredza.
Kunyangwe iyi sarudzo inogona kusakanganisa musika weUS, haidzivisi 6GHz kubva pakuva bhendi repasi rose. Zvakare, iyo yakaderera frequency yebhendi iyi inoita kuti kuwana yekuvhara yekunze kwakafanana ne3.5GHz kusanyanya kuoma. 5G ichaunza imwe yechipiri wave yepamusoro yekuvaka.
Zvinoenderana nekufanotaura kweGSMA, iyi inotevera wave yekuvaka 5G ichatanga muna 2025, ichimaka hafu yechipiri ye5G: 5G-A. Isu tinotarisira kushamisika kuchaunzwa ne5G-A.
Concept Microwave inyanzvi inogadzira zvinhu zve5G/6G RF muChina, kusanganisira iyo RF lowpass sefa, highpass sefa, bandpass sefa, notch sefa/bhendi stop filter, duplexer,Simba divider uye directional coupler. Ese anogona kugadzirwa zvinoenderana nezvinodiwa zvako.
