Kugoverwa kwe6GHz Spectrum Kwakapedzwa
Musangano weWRC-23 (World Radiocommunication Conference 2023) wakapera muDubai nguva pfupi yadarika, wakarongwa neInternational Telecommunication Union (ITU), nechinangwa chekubatanidza kushandiswa kwemagetsi epasi rose.
Kuva ne6GHz spectrum ndiko kwaive chinhu chikuru chainyanya kutariswa pasi rose.
Musangano wacho wakasarudza: Kugovera bhendi re6.425-7.125GHz (700MHz bandwidth) kumasevhisi enharembozha, kunyanya kutaurirana kwenharembozha ye5G.
Chii chinonzi 6GHz?
6GHz inoreva huwandu hwema spectrum kubva pa5.925GHz kusvika pa7.125GHz, ine bandwidth inosvika 1.2GHz. Kare, ma frequency spectra akapihwa pakati kusvika pasi ekutaurirana kwefoni aitove nekushandiswa kwakasarudzika, kushandiswa kwe6GHz spectrum chete kwaisava pachena. Muganho wekutanga wepamusoro weSub-6GHz ye5G waive 6GHz, pamusoro payo pane mmWave. Nekuwedzera kwehupenyu hwe5G kunotarisirwa uye mikana yakaipa yekutengeserana yemmWave, kuisa 6GHz zviri pamutemo kwakakosha kune chikamu chinotevera chekuvandudzwa kwe5G.
3GPP yakatogadzirisa hafu yepamusoro ye6GHz, kunyanya 6.425-7.125MHz kana 700MHz, muRelease 17, inozivikanwawo seU6G ine frequency band insignificant n104.
Wi-Fi yave ichikwikwidzanawo ne6GHz. NeWi-Fi 6E, 6GHz yave kuiswa mu standard. Sezvakaratidzwa pazasi, ne6GHz, ma Wi-Fi bands achakura kubva pa600MHz mu2.4GHz ne5GHz kusvika pa1.8GHz, uye 6GHz inotsigira bandwidth inosvika 320MHz kune carrier imwe chete muWi-Fi.
Sekureva kwemushumo weWi-Fi Alliance, Wi-Fi parizvino inopa network yakawanda, zvichiita kuti 6GHz ive remangwana reWi-Fi. Zvinodiwa kubva pakutaurirana nefoni zve6GHz hazvina musoro sezvo akawanda ma spectrum achiri kushandiswa.
Mumakore achangopfuura, kwave nemaonero matatu pamusoro pekuva ne6GHz: Chekutanga, kuiisa zvizere kuWi-Fi. Chechipiri, kuiisa zvizere kumafoni ekutaurirana (5G). Chechitatu, kuiisa zvakaenzana pakati pezviviri.
Sezvatinoona pawebhusaiti yeWi-Fi Alliance, nyika dziri muAmerica dzakanyanya kupa Wi-Fi 6GHz yese, nepo Europe ichida kupa Wi-Fi chidimbu chidiki. Zvinonzwisisika kuti chidimbu chepamusoro chasara chinoenda ku5G.
Sarudzo yeWRC-23 inogona kuonekwa sekusimbisa chibvumirano chakasimbiswa, ichiwana kuhwina pakati pe5G neWi-Fi kuburikidza nemakwikwi pamwe nekubvumirana.
Kunyangwe sarudzo iyi ingasakanganisa musika weUS, haidziviriri 6GHz kuti isave bhendi yepasi rose. Uyezve, kuwanda kwebhendi iyi kunoita kuti kuwana nzvimbo yekunze yakafanana ne3.5GHz kusaome zvakanyanya. 5G ichaunza nhanho yechipiri yekukura kwemusika.
Zvichienderana nefungidziro yeGSMA, kuvakwa kwe5G kunotevera kuchatanga muna 2025, zvichiratidza chikamu chechipiri che5G: 5G-A. Tinotarisira kushamisika kuchaunzwa ne5G-A.
Concept Microwave inyanzvi yekugadzira zvikamu zve5G/6G 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.
