Spectrum ya 6GHz, Tsogolo la 5G

Kugawa kwa 6GHz Spectrum Kwamalizidwa

Msonkhano wa WRC-23 (World Radiocommunication Conference 2023) womwe unachitikira ku Dubai posachedwapa, womwe unakonzedwa ndi International Telecommunication Union (ITU), cholinga chake chinali kugwirizanitsa kagwiritsidwe ntchito ka magetsi padziko lonse lapansi.

Ufulu wa 6GHz spectrum unali chinthu chofunika kwambiri padziko lonse lapansi.

Msonkhanowu unasankha izi: Kugawa gulu la 6.425-7.125GHz (bandwidth ya 700MHz) pa ntchito zamafoni, makamaka pa mauthenga amafoni a 5G.

Kodi 6GHz ndi chiyani?

6GHz imatanthauza kuchuluka kwa ma spectrum kuyambira 5.925GHz mpaka 7.125GHz, ndi bandwidth mpaka 1.2GHz. Kale, ma frequency spectra omwe analipo pakati mpaka otsika kwambiri pa mafoni anali kale ogwiritsidwa ntchito, ndipo kugwiritsa ntchito ma spectrum a 6GHz okha sikunali kodziwika bwino. Malire oyamba apamwamba a Sub-6GHz a 5G anali 6GHz, pamwamba pake pali mmWave. Ndi kukulitsa kwa moyo wa 5G komwe kumayembekezeredwa komanso mwayi woipa wamalonda wa mmWave, kuphatikiza 6GHz mwalamulo ndikofunikira kwambiri pa gawo lotsatira la chitukuko cha 5G.

3GPP yakhazikitsa kale gawo lapamwamba la 6GHz, makamaka 6.425-7.125MHz kapena 700MHz, mu Release 17, yomwe imadziwikanso kuti U6G yokhala ndi dzina la frequency band n104.

Wi-Fi yakhala ikupikisananso ndi 6GHz. Ndi Wi-Fi 6E, 6GHz yaphatikizidwa mu muyezo. Monga momwe tawonetsera pansipa, ndi 6GHz, ma Wi-Fi band adzakula kuchoka pa 600MHz mu 2.4GHz ndi 5GHz mpaka 1.8GHz, ndipo 6GHz idzathandizira bandwidth mpaka 320MHz kwa kampani imodzi ya Wi-Fi.

Malinga ndi lipoti la Wi-Fi Alliance, Wi-Fi pakadali pano imapereka mphamvu zambiri pa netiweki, zomwe zimapangitsa kuti 6GHz ikhale tsogolo la Wi-Fi. Zofunikira kuchokera ku mauthenga apafoni pa 6GHz sizoyenera chifukwa ma spectrum ambiri sagwiritsidwa ntchito.

M'zaka zaposachedwapa, pakhala malingaliro atatu okhudza umwini wa 6GHz: Choyamba, kugawa mokwanira ku Wi-Fi. Chachiwiri, kugawa mokwanira ku mauthenga a pafoni (5G). Chachitatu, kugawa mofanana pakati pa awiriwa.

Monga momwe zikuonekera patsamba la Wi-Fi Alliance, mayiko aku America nthawi zambiri apereka 6GHz yonse ku Wi-Fi, pomwe Europe ikufuna kugawa gawo lotsika ku Wi-Fi. Zachidziwikire, gawo lapamwamba lotsalalo limapita ku 5G.

Chisankho cha WRC-23 chingaganizidwe ngati chitsimikizo cha mgwirizano womwe wakhazikitsidwa, kukwaniritsa kupambana pakati pa 5G ndi Wi-Fi kudzera mu mpikisano ndi mgwirizano.

Ngakhale chisankhochi sichingakhudze msika wa ku America, sichiletsa 6GHz kukhala gulu lodziwika padziko lonse lapansi. Kuphatikiza apo, kuchuluka kochepa kwa gululi kumapangitsa kuti kufalikira kwakunja kofanana ndi 3.5GHz kusakhale kovuta kwambiri. 5G idzayambitsa mafunde achiwiri a nthawi yomanga.

Malinga ndi zomwe GSMA yalosera, mafunde otsatirawa a zomangamanga za 5G adzayamba mu 2025, zomwe zikusonyeza theka lachiwiri la 5G: 5G-A. Tikuyembekezera zodabwitsa zomwe 5G-A idzabweretse.

Concept Microwave ndi kampani yopanga zinthu za 5G/6G RF ku China, kuphatikizapo fyuluta ya RF lowpass, fyuluta ya highpass, fyuluta ya bandpass, fyuluta ya notch/band stop, duplexer, Power divider ndi directional coupler. Zonsezi zitha kusinthidwa malinga ndi zomwe mukufuna.
