Nge-WRC-23 ezayo (iNkomfa yeHlabathi yeRadiocommunication ka-2023), ingxoxo kwi-6GHz yokucwangcisa iya ishushu ekhaya nakwamanye amazwe.
Iyonke i-6GHz ine-bandwidth iyonke ye-1200MHz (5925-7125MHz).Umba ngowokuba unikezele ngee-IMTs ze-5G (njengesibonwa selayisenisi) okanye i-Wi-Fi 6E (njengesspectrum esingagunyaziswanga)
Umnxeba wokwabela i-spectrum yelayisensi ye-5G ivela kwinkampu ye-IMT esekelwe kwi-3GPP 5G iteknoloji.
Kwi-IMT 5G, i-6GHz yenye i-spectrum ye-mid-band emva kwe-3.5GHz (3.3-4.2GHz, 3GPP n77).Xa kuthelekiswa ne-millimeter wave band, ibhendi yamaza aphakathi inokhuselo olunamandla.Xa kuthelekiswa nebhendi ephantsi, ibhendi ephakathi inezixhobo ezininzi ze-spectrum.Ke ngoko, yeyona nkxaso ibalulekileyo yebhendi ye5G.
I-6GHz ingasetyenziselwa i-broadband yeselula (i-eMBB) kwaye, ngoncedo lwee-eriyali ze-high-gain ze-directional kunye ne-beamforming, kwi-Fixed Wireless Access (i-wideband).I-GSMA kutshanje iye yade yabiza ukusilela koorhulumente ukusebenzisa i-6GHz njenge-spectrum enelayisensi yokubeka emngciphekweni uphuhliso lwehlabathi lwe-5G.
Inkampu ye-Wi-Fi, esekwe kwitekhnoloji ye-IEEE802.11, ibeka phambili imbono eyahlukileyo: I-Wi-Fi ibaluleke kakhulu kwiintsapho nakumashishini, ngakumbi ngexesha lobhubhani we-COVID-19 ngo-2020, xa iWi-Fi iyeyona shishini ledatha. .Okwangoku, i-2.4GHz kunye ne-5GHz iibhendi ze-Wi-Fi, ezinikezela ngamakhulu ambalwa e-MHz, ziye zaxinana kakhulu, ezichaphazela amava omsebenzisi.I-Wi-Fi idinga i-spectrum eninzi ukuxhasa imfuno ekhulayo.Ukongezwa kwe-6GHz yebhendi ye-5GHz yangoku ibalulekile kwi-ecosystem ye-Wi-Fi yexesha elizayo.
Ubume bokuhanjiswa kwe-6GHz
Ehlabathini lonke, iNgingqi ye-ITU yesi-2 (eUnited States, eCanada, eLatin America) ngoku isetelwe ukusebenzisa yonke i-1.2GHz ye-Wi-Fi.Eyona nto ibalaseleyo yi-United States neCanada, evumela i-4W EIRP yemveliso eqhelekileyo ye-AP kwezinye iibhendi zamaza.
EYurophu, kwamkelwa isimo sengqondo esilungeleleneyo.Ibhendi yefrikhwensi ephantsi (5925-6425MHz) ivulekele i-Wi-Fi yamandla aphantsi (200-250mW) yi-CEPT yaseYurophu kunye ne-UK Ofcom, ngelixa ibhendi yefrikhwensi ephezulu (6425-7125MHz) ayikagqitywa okwangoku.Kwi-Ajenda 1.2 ye-WRC-23, iYurophu iya kuqwalasela ukucwangcisa i-6425-7125MHz kunxibelelwano lwe-IMT oluphathwayo.
KuMmandla we-3 we-Asia-Pacific, iJapan kunye ne-South Korea ngaxeshanye zivule yonke i-spectrum kwi-Wi-Fi engavumelekanga.I-Australia kunye ne-New Zealand sele iqalile ukucela izimvo zoluntu, kwaye isicwangciso sabo esiphambili siyafana neso saseYurophu, oko kukuthi, ukuvula i-frequency band ephantsi ekusebenziseni okungagunyaziswanga, ngelixa i-high frequency band ilinda-ubone.
Nangona ugunyaziwe wespectrum welizwe ngalinye wamkela umgaqo-nkqubo “wokungathathi cala komgangatho wobugcisa”, oko kukuthi i-Wi-Fi, i-5G NR engenalayisenisi ingasetyenziswa, kodwa ukusuka kwi-ecosystem yezixhobo zangoku kunye namava e-5GHz adlulileyo, okoko nje i-frequency band ayinalayisenisi, i-Wi- I-Fi inokulawula imarike ngexabiso eliphantsi, ukuhanjiswa okulula kunye nesicwangciso sabadlali abaninzi.
Njengelizwe elinophuhliso lonxibelelwano olungcono, i-6GHz ivuleleke ngokuyinxenye okanye ivuleleke ngokupheleleyo kwi-Wi-Fi 6E emhlabeni.
