Ndi WRC-23 yomwe ikubwera (2023 World Radiocommunication Conference), zokambirana zakukonzekera kwa 6GHz zikutenthedwa kunyumba ndi kunja.
6GHz yonse ili ndi bandwidth yonse ya 1200MHz (5925-7125MHz).Nkhani ndi yoti mugawire 5G IMTs (monga sipekitiramu yovomerezeka) kapena Wi-Fi 6E (monga sipekitiramu yopanda chilolezo)
Kuyitanira kuti agawidwe sipekitiramu yovomerezeka ya 5G imachokera ku kampu ya IMT yotengera ukadaulo wa 3GPP 5G.
Kwa IMT 5G, 6GHz ndi sipekitiramu ina yapakatikati pambuyo pa 3.5GHz (3.3-4.2GHz, 3GPP n77).Poyerekeza ndi millimeter wave band, bandi yapakati pafupipafupi imakhala ndi kuphimba kolimba.Poyerekeza ndi gulu lotsika, gulu lapakati lili ndi zowonjezera zambiri.Chifukwa chake, ndiye chithandizo chofunikira kwambiri cha 5G.
6GHz itha kugwiritsidwa ntchito pa burodibandi yam'manja (eMBB) ndipo, mothandizidwa ndi tinyanga tambiri tomwe timalowera komanso kuwongolera, pa Fixed Wireless Access (wideband).Posachedwapa GSMA idapita mpaka kuyitanitsa kuti maboma alephere kugwiritsa ntchito 6GHz ngati sipekitiramu yovomerezeka kuti awononge chiyembekezo cha chitukuko cha 5G padziko lonse lapansi.
Msasa wa Wi-Fi, wotengera luso la IEEE802.11, umapereka malingaliro ena: Wi-Fi ndiyofunikira kwambiri kwa mabanja ndi mabizinesi, makamaka panthawi ya mliri wa COVID-19 mu 2020, pomwe Wi-Fi ndiye bizinesi yayikulu ya data. .Pakalipano, magulu a 2.4GHz ndi 5GHz Wi-Fi, omwe amapereka mazana ochepa a MHz okha, akhala odzaza kwambiri, zomwe zimakhudza ogwiritsa ntchito.Wi-Fi ikufunika sipekitiramu yowonjezera kuti ithandizire kufunikira kowonjezereka.Kukulitsa kwa 6GHz kwa bandi yaposachedwa ya 5GHz ndikofunikira ku chilengedwe chamtsogolo cha Wi-Fi.
Mkhalidwe wogawa wa 6GHz
Padziko lonse, ITU Region 2 (United States, Canada, Latin America) tsopano yakhazikitsidwa kuti igwiritse ntchito 1.2GHz yonse pa Wi-Fi.Odziwika kwambiri ndi United States ndi Canada, omwe amalola 4W EIRP ya AP yotuluka mumagulu ena pafupipafupi.
Ku Ulaya, anthu amatengera maganizo oyenera.Bandi yotsika pafupipafupi (5925-6425MHz) imatsegulidwa ku Wi-Fi yamphamvu (200-250mW) ndi European CEPT ndi UK Ofcom, pomwe gulu lapamwamba (6425-7125MHz) silinaganizidwebe.Mu Agenda 1.2 ya WRC-23, Europe ilingalira zokonzekera 6425-7125MHz pakulankhulana kwapamanja kwa IMT.
M'chigawo cha 3 Asia-Pacific, Japan ndi South Korea nthawi imodzi atsegula mawonekedwe onse ku Wi-Fi wopanda chilolezo.Australia ndi New Zealand ayamba kupempha maganizo a anthu, ndipo ndondomeko yawo yaikulu ndi yofanana ndi ya ku Ulaya, ndiko kuti, kutsegula otsika pafupipafupi bandi kuti agwiritse ntchito mosaloledwa, pamene gulu lapamwamba lapamwamba likudikirira ndikuwona.
Ngakhale olamulira a dziko lililonse amatengera mfundo za "kusalowerera ndale kwaukadaulo", kutanthauza Wi-Fi, 5G NR yopanda chilolezo ingagwiritsidwe ntchito, koma kuchokera ku zida zamakono komanso zomwe zidachitika kale 5GHz, bola ngati gulu la frequency lilibe chilolezo, Wi- Fi imatha kulamulira msika ndi mtengo wotsika, kutumiza mosavuta komanso njira zamasewera ambiri.
Monga dziko lomwe lili ndi chitukuko chabwino kwambiri cholumikizirana, 6GHz ndi yotseguka pang'ono kapena kwathunthu ku Wi-Fi 6E padziko lonse lapansi.
