Ngengqungquthela ezayo ye-WRC-23 (2023 World Radiocommunication Conference), ingxoxo yokuhlela i-6GHz iya ishuba ekhaya naphesheya.
I-6GHz yonke inomkhawulokudonsa ophelele we-1200MHz (5925-7125MHz).Okubangwayo ukuthi kufanele kwabiwe yini i-5G IMTs (njenge-spectrum enelayisensi) noma i-Wi-Fi 6E (njenge-spectrum engagunyaziwe)
Ucingo lokwaba i-spectrum enelayisensi ye-5G luvela ekamu le-IMT elisekelwe kubuchwepheshe be-3GPP 5G.
Ku-IMT 5G, i-6GHz ingenye i-spectrum ye-mid-band ngemva kwe-3.5GHz (3.3-4.2GHz, 3GPP n77).Uma kuqhathaniswa nebhendi ye-millimeter wave, ibhendi yefrikhwensi emaphakathi inokufakwa okuqinile.Uma kuqhathaniswa nebhendi ephansi, ibhendi emaphakathi inezinsiza eziningi ze-spectrum.Ngakho-ke, iwusekelo lwebhendi olubaluleke kakhulu lwe-5G.
I-6GHz ingasetshenziselwa i-broadband yeselula (eMBB) futhi, ngosizo lwama-antenna aqondisayo anenzuzo ephezulu kanye nokwenza i-beamforming, Ukufinyelela Okungenantambo Okungenantambo (i-wideband).I-GSMA muva nje iye yaze yabiza ukwehluleka kohulumeni ukusebenzisa i-6GHz njengesibonisi esinelayisensi ukubeka engcupheni amathuba entuthuko ye-5G yomhlaba.
Ikamu le-Wi-Fi, elisekelwe kubuchwepheshe be-IEEE802.11, libeka phambili umbono ohlukile: I-Wi-Fi ibaluleke kakhulu emindenini nasemabhizinisini, ikakhulukazi phakathi nobhubhane lwe-COVID-19 ngo-2020, lapho i-Wi-Fi iyibhizinisi ledatha eliyinhloko. .Njengamanje, amabhendi e-2.4GHz kanye ne-5GHz Wi-Fi, ahlinzeka ngama-MHz angamakhulu ambalwa kuphela, asegcwele kakhulu, okuthinta ulwazi lomsebenzisi.I-Wi-Fi idinga i-spectrum eyengeziwe ukuze isekele isidingo esikhulayo.Isandiso se-6GHz sebhendi yamanje engu-5GHz sibalulekile ku-ecosystem ye-Wi-Fi yesikhathi esizayo.
Isimo sokusabalalisa se-6GHz
Emhlabeni jikelele, i-ITU Region 2 (United States, Canada, Latin America) manje isimiselwe ukusebenzisa yonke i-1.2GHz ye-Wi-Fi.Okugqame kakhulu i-United States ne-Canada, evumela i-4W EIRP yokuphuma okujwayelekile kwe-AP kwamanye amabhendi efrikhwensi.
EYurophu, kwamukelwa isimo sengqondo esilinganiselayo.Ibhendi yefrikhwensi ephansi (5925-6425MHz) ivulekele i-Wi-Fi enamandla aphansi (200-250mW) yi-European CEPT ne-UK Ofcom, kuyilapho ibhendi yefrikhwensi ephezulu (6425-7125MHz) ayikanqunywa.Ku-Ajenda 1.2 ye-WRC-23, i-Europe izocabangela ukuhlela i-6425-7125MHz yokuxhumana kweselula kwe-IMT.
Esifundeni sesi-3 sase-Asia-Pacific, i-Japan ne-South Korea ngasikhathi sinye zivule yonke i-spectrum ku-Wi-Fi engenalayisense.I-Australia ne-New Zealand sebeqalile ukucela imibono yomphakathi, futhi icebo labo eliyinhloko lifana nelase-Europe, okungukuthi, ukuvula ibhendi yefrikhwensi ephansi ukuze isetshenziswe ngokungagunyaziwe, kuyilapho ibhendi yefrikhwensi ephezulu ingukulinda futhi ubone.
Nakuba isiphathimandla se-spectrum sezwe ngalinye samukela inqubomgomo “yokungathathi hlangothi okujwayelekile kobuchwepheshe”, okungukuthi i-Wi-Fi, i-5G NR engenalayisense ingasetshenziswa, kodwa kusukela ku-ecosystem yamanje yezinto zokusebenza kanye nolwazi oludlule lwe-5GHz, inqobo nje uma ibhendi yefrikhwensi ingenayo ilayisensi, i-Wi- I-Fi ingabusa imakethe ngezindleko eziphansi, ukuthunyelwa okulula namasu wabadlali abaningi.
Njengezwe elinomfutho ongcono kakhulu wokuthuthukisa ukuxhumana, i-6GHz ivuleleke kancane noma ngokugcwele ku-Wi-Fi 6E emhlabeni.
