C-band, ụdịdị dị iche iche nke redio nwere oke n'etiti 3.4 GHz na 4.2 GHz, na-arụ ọrụ dị mkpa na netwọkụ 5G. Àgwà ya pụrụ iche na-eme ka ọ dị mkpa iji nweta ọrụ 5G na-agba ọsọ dị elu, nke dị ala na nke obosara.
1. Mkpuchi nha nha na ọsọ nnyefe
The C-band bụ nke etiti-band ụdịdị dị iche iche, nke nwere ike inye ezigbo nguzozi n'etiti mkpuchi na ọsọ nnyefe data. E jiri ya tụnyere obere band, C-band nwere ike ịnye ọnụego nnyefe data dị elu; ma jiri ya tụnyere ụgbụ dị elu (dị ka ebili mmiri millimeter), C-band nwere mkpuchi sara mbara. Ntụle a na-eme ka C-band dị mma maka ibugharị netwọkụ 5G n'ime obodo mepere emepe na mpaghara ime obodo, na-ahụ na ndị ọrụ na-enweta njikọ ọsọ ọsọ ma na-ebelata ọnụ ọgụgụ ọdụ ụgbọ ala ebugara.
2. Akwa ụdịdị dị iche iche
C-band na-enye bandwit dị iche iche iji kwado ikike data ka ukwuu. Dịka ọmụmaatụ, Federal Communications Commission (FCC) nke United States kenyere 280 MHz nke mid-band spectrum maka 5G na C-band wee ree ya na njedebe nke 2020. Ndị na-arụ ọrụ dịka Verizon na AT&T nwetara nnukwu ụdịdị dị iche iche. akụrụngwa n'ahịa ahịa a, na-enye ntọala siri ike maka ọrụ 5G ha.
3. Kwado teknụzụ 5G dị elu
Njirimara ugboro ugboro nke C-band na-enyere ya aka ịkwado teknụzụ ndị isi na netwọk 5G, dị ka nnukwu MIMO (ọtụtụ ntinye ntinye ọtụtụ) na nhazi ọkụ. Teknụzụ ndị a nwere ike melite arụmọrụ ụdịdị dị iche iche, kwalite ikike netwọkụ, yana kwalite ahụmịhe onye ọrụ. Tụkwasị na nke ahụ, uru bandwit nke C-band na-enyere ya aka izute ngwa ngwa dị elu na nke dị ala nke ngwa 5G n'ọdịnihu, dị ka eziokwu augmented (AR), Virtual Reality (VR), na Ịntanetị nke Ihe (IoT). ).
4. Ngwa zuru ụwa ọnụ
Ọtụtụ mba na mpaghara ejirila C-band dị ka eriri ugboro ugboro maka netwọk 5G. Dịka ọmụmaatụ, ọtụtụ mba dị na Europe na Eshia na-eji n78 band (3.3 ruo 3.8 GHz), ebe United States na-eji n77 band (3.3 ruo 4.2 GHz). Nkwekọrịta zuru ụwa ọnụ a na-enyere aka ịmepụta usoro gburugburu ebe obibi 5G jikọtara ọnụ, kwalite ndakọrịta akụrụngwa na teknụzụ, yana mee ka mgbasawanye na ngwa nke 5G dịkwuo elu.
5. Kwalite ntinye azụmahịa 5G
Atụmatụ doro anya na oke nke C-band spectrum emeela ka mbugharị azụmahịa nke netwọkụ 5G dị ngwa ngwa. Na China, Ministry of Industry and Information Technology akọwapụtala nke ọma 3300-3400 MHz (eji ime ụlọ na ụkpụrụ), 3400-3600 MHz na 4800-5000 MHz bands dị ka eriri arụ ọrụ nke sistemụ 5G. Atụmatụ a na-enye ntụziaka doro anya maka nyocha na mmepe na ịzụ ahịa nke akụrụngwa usoro, ibe, ọnụ na ngwa ule, ma na-akwalite azụmahịa nke 5G.
Na nchịkọta, C-band na-arụ ọrụ dị mkpa na netwọk 5G. Uru ya na mkpuchi, ọsọ nnyefe, akụrụngwa ụdịdị na nkwado teknụzụ na-eme ka ọ bụrụ ntọala dị mkpa maka ịghọta ọhụụ 5G. Ka mgbasa ozi 5G zuru ụwa ọnụ na-aga n'ihu, ọrụ nke C-band ga-adịwanye mkpa, na-ewetara ndị ọrụ ahụmịhe nkwurịta okwu ka mma.
