Emechaala nkesa nke 6GHz Spectrum
Nzukọ WRC-23 (World Radiocommunication Conference 2023) mechiri n'oge na-adịbeghị anya na Dubai, nke International Telecommunication Union (ITU) haziri, na-achọ ịhazi ojiji spectrum zuru ụwa ọnụ.
Nnweta nke 6GHz spectrum bụ isi ihe na-adọrọ mmasị n'ụwa niile.
Nzukọ ahụ kpebiri: Inye band 6.425-7.125GHz (bandwit 700MHz) maka ọrụ mkpanaka, karịsịa maka nkwukọrịta ekwentị 5G.
Kedu ihe bụ 6GHz?
6GHz na-ezo aka na oke spectrum site na 5.925GHz ruo 7.125GHz, yana bandwit ruo 1.2GHz. Na mbụ, spectra ugboro ole etiti ruo ala nke e kenyere maka nkwukọrịta mkpanaka enweelarị ojiji pụrụ iche, naanị ngwa nke spectrum 6GHz ka edoghị anya. Oke elu mbụ akọwapụtara nke Sub-6GHz maka 5G bụ 6GHz, nke dị n'elu nke bụ mmWave. Site na ndọtị ndụ 5G a tụrụ anya ya na atụmanya azụmahịa dị njọ maka mmWave, itinye 6GHz n'ụzọ iwu kwadoro dị oke mkpa maka usoro mmepe 5G na-esote.
3GPP ahaziela ọkara elu nke 6GHz, ọkachasị 6.425-7.125MHz ma ọ bụ 700MHz, na Mwepụta 17, nke a makwaara dị ka U6G yana aha ugboro ugboro n104.
Wi-Fi na-asọ mpi maka 6GHz. Site na Wi-Fi 6E, 6GHz abanyela na ọkọlọtọ ahụ. Dịka egosiri n'okpuru, site na 6GHz, eriri Wi-Fi ga-agbasa site na 600MHz na 2.4GHz na 5GHz ruo 1.8GHz, 6GHz ga-akwadokwa bandwidth ruo 320MHz maka otu onye na-ebu Wi-Fi.
Dịka akụkọ sitere n'aka Wi-Fi Alliance si kwuo, Wi-Fi na-enye ọtụtụ ikike netwọkụ ugbu a, nke na-eme ka Wi-Fi bụrụ ọdịnihu 6GHz. Ihe ndị a chọrọ site na nkwukọrịta ekwentị maka 6GHz enweghị ezi uche ebe ọ bụ na ọtụtụ spectrum ka na-adịghị eji.
N'afọ ndị na-adịbeghị anya, e nweela echiche atọ gbasara inwe 6GHz: Nke mbụ, kewaa ya kpamkpam na Wi-Fi. Nke abụọ, kewaa ya kpamkpam na nkwukọrịta ekwentị mkpanaaka (5G). Nke atọ, kewaa ya nhata n'etiti ha abụọ.
Dịka a pụrụ ịhụ na weebụsaịtị Wi-Fi Alliance, mba dị na Amerịka ekenyela Wi-Fi 6GHz dum, ebe Yuropu na-achọ ikenye Wi-Fi nke dị ala. Dịka o kwesịrị, akụkụ elu fọdụrụ na-aga na 5G.
Mkpebi WRC-23 nwere ike ịbụ nkwenye nke nkwekọrịta e guzobere, na-enweta mmeri n'etiti 5G na Wi-Fi site na asọmpi na nkwekọrịta.
Ọ bụ ezie na mkpebi a nwere ike ọ gaghị emetụta ahịa US, ọ naghị egbochi 6GHz ịghọ otu band zuru ụwa ọnụ. Ọzọkwa, obere ugboro nke band a na-eme ka ọ ghara isi ike inweta mkpuchi n'èzí dị ka 3.5GHz. 5G ga-ebute mmụba nke abụọ nke ọrụ owuwu.
Dịka amụma GSMA si kwuo, usoro owuwu 5G ọzọ a ga-amalite na 2025, nke ga-abụ ọkara nke abụọ nke 5G: 5G-A. Anyị na-atụ anya ihe ijuanya 5G-A ga-eweta.
Ngwa Ngwa Ngwakọta Concept bụ ọkachamara n'ịmepụta ihe mejupụtara 5G/6G RF na China, gụnyere nzacha RF lowpass, nzacha highpass, nzacha bandpass, nzacha notch/band stop filter, duplexer, Power divider na direction coupler. Enwere ike ịhazi ha niile dịka ihe ị chọrọ si dị.
