Hamwe na WRC-23 yimirije (2023 Ihuriro ryisi ya Radiyo Itumanaho), ikiganiro kuri gahunda ya 6GHz kirashyuha mugihugu ndetse no mumahanga.
6GHz yose ifite umurongo wa 1200MHz (5925-7125MHz).Ikibazo ni ukumenya 5G IMTs (nkibikoresho byemewe) cyangwa Wi-Fi 6E (nkibikoresho bitemewe)
Ihamagarwa ryo gutanga 5G ryemewe ryavuye mu nkambi ya IMT ishingiye ku ikoranabuhanga rya 3GPP 5G.
Kuri IMT 5G, 6GHz nubundi buryo bwo hagati ya bande nyuma ya 3.5GHz (3.3-4.2GHz, 3GPP n77).Ugereranije na milimetero yumurongo wumurongo, umurongo wo hagati ufite umurongo ukomeye.Ugereranije na bande yo hasi, bande yo hagati ifite ibintu byinshi byerekana ibintu.Kubwibyo, nigikorwa cyingenzi cya bande ya 5G.
6GHz irashobora gukoreshwa mugukwirakwiza mugari (eMBB) kandi, hifashishijwe antenne yunguka cyane kandi ikanamurika, kuri Fixed Wireless Access (Broadband).GSMA iherutse kugera aho isaba ko leta zananirwa gukoresha 6GHz nk'impushya zemewe kugira ngo zibangamire iterambere rya 5G ku isi.
Inkambi ya Wi-Fi, ishingiye ku ikoranabuhanga rya IEEE802.11, itanga ibitekerezo bitandukanye: Wi-Fi ifite akamaro gakomeye mu miryango no mu mishinga, cyane cyane mu gihe cy'icyorezo cya COVID-19 mu 2020, igihe Wi-Fi ari yo bucuruzi bw'ingenzi bw'amakuru. .Kugeza ubu, imirongo ya 2.4GHz na 5GHz ya Wi-Fi, itanga MHz magana make gusa, yahindutse abantu benshi, bigira ingaruka ku bunararibonye bw'abakoresha.Wi-Fi ikenera ibintu byinshi kugirango ishyigikire ibisabwa.Kwiyongera kwa 6GHz ya bande ya 5GHz ningirakamaro kubuzima bwa kazoza ka Wi-Fi.
Ikwirakwizwa rya 6GHz
Kwisi yose, ITU Region 2 (Amerika, Kanada, Amerika y'Epfo) ubu igiye gukoresha 1.2GHz yose kuri Wi-Fi.Ikigaragara cyane ni Amerika na Kanada, byemerera 4W EIRP yumusaruro usanzwe AP mumatsinda amwe.
Mu Burayi, hafatwa imyifatire iboneye.Umuyoboro muke (5925-6425MHz) ufunguye Wi-Fi ifite ingufu nke (200-250mW) na Europe CEPT na UK Ofcom, mugihe umurongo mwinshi (6425-7125MHz) utaramenyekana.Muri Gahunda ya 1.2 ya WRC-23, Uburayi buzatekereza gutegura 6425-7125MHz yo gutumanaho kwa IMT.
Mu Karere ka 3 Aziya-Pasifika, Ubuyapani na Koreya yepfo byafunguye icyarimwe icyerekezo cyose kuri Wi-Fi idafite uruhushya.Australiya na Nouvelle-Zélande byatangiye gusaba ibitekerezo byabaturage, kandi gahunda yabo nyamukuru isa niy'Uburayi, ni ukuvuga gufungura umurongo muto wa radiyo yo gukoresha utabifitiye uburenganzira, mugihe umurongo mwinshi utegereje-ukareba.
Nubwo buri gihugu gishinzwe kugenzura ibikorwa bya politiki yo "kutabogama kwa tekiniki", aribyo Wi-Fi, 5G NR itabifitiye uburenganzira irashobora gukoreshwa, ariko uhereye kubikoresho byubu bigezweho ndetse nubunararibonye bwa 5GHz, mugihe cyose umurongo wa radiyo utabifitiye uburenganzira, Wi- Fi irashobora kuganza isoko hamwe nigiciro gito, kohereza byoroshye hamwe ningamba zabakinnyi benshi.
Nkigihugu gifite umuvuduko mwiza witerambere ryitumanaho, 6GHz irakinguye igice cyangwa yuzuye kuri Wi-Fi 6E kwisi.
