C-band, radiyo ifite radiyo ifite intera iri hagati ya 3.4 GHz na 4.2 GHz, igira uruhare runini mumiyoboro ya 5G. Ibiranga bidasanzwe bituma iba urufunguzo rwo kugera ku muvuduko wihuse, ubukererwe buke, no gukwirakwiza serivisi 5G.
1. Kuringaniza gukwirakwiza no kwihuta
C-bande iri murwego rwo hagati rwagati, rushobora gutanga uburinganire bwiza hagati yo gukwirakwiza no kwihuta kwamakuru. Ugereranije na bande yo hasi, C-band irashobora gutanga igipimo cyinshi cyo kohereza amakuru; kandi ugereranije na bande yumurongo mwinshi (nka milimetero umuraba), C-band ifite ubwaguke bwagutse. Iringaniza rituma C-band ikwiranye cyane no gukoresha imiyoboro ya 5G mumijyi no mumijyi, byemeza ko abakoresha babona imiyoboro yihuse mugihe bagabanya umubare wibibanza byoherejwe.
2. Ibikoresho byinshi byerekana ibintu byinshi
C-band itanga umurongo mugari wo gushyigikira amakuru menshi. Kurugero, komisiyo ishinzwe itumanaho (FCC) yo muri Reta zunzubumwe zamerika yageneye 280 MHz yumurongo wo hagati wa 5G muri C-band hanyuma ikagurisha cyamunara mu mpera za 2020. Abakora nka Verizon na AT&T babonye ibintu byinshi umutungo muri cyamunara, utanga umusingi ukomeye kuri serivisi zabo 5G.
3. Shigikira tekinoroji ya 5G
Imirongo yumurongo wa C-band ituma ishobora gushyigikira neza tekinoroji yingenzi mumiyoboro ya 5G, nka MIMO nini (byinshi-byinjiza byinshi-bisohoka) no kumurika. Izi tekinoroji zirashobora kunoza imikorere ya sprifike, kuzamura ubushobozi bwurusobe, no kunoza uburambe bwabakoresha. Mubyongeyeho, ubwinshi bwumurongo wa C-band butuma bujuje ibisabwa byihuta kandi byihuta bisabwa mubisabwa 5G bizaza, nkibintu byongerewe ukuri (AR), ukuri kugaragara (VR), na interineti yibintu (IoT) ).
4. Porogaramu yagutse kwisi yose
Ibihugu byinshi nakarere byakoresheje C-band nkumuyoboro nyamukuru wa 5G. Kurugero, ibihugu byinshi muburayi na Aziya bikoresha umurongo wa n78 (3.3 kugeza 3.8 GHz), mugihe Amerika ikoresha bande ya n77 (3.3 kugeza 4.2 GHz). Uku guhuzagurika kwisi bifasha gushiraho urusobe rwibinyabuzima 5G, guteza imbere guhuza ibikoresho nikoranabuhanga, no kwihutisha kumenyekanisha no gukoresha 5G.
5. Gutezimbere ibikorwa bya 5G byoherezwa mubucuruzi
Igenamigambi risobanutse no kugabura C-band byihutishije kohereza ubucuruzi bwa 5G. Mu Bushinwa, Minisiteri y’inganda n’ikoranabuhanga mu itumanaho yashyizeho neza MHz 3300-3400 (ikoreshwa mu nzu mu buryo bwihariye), 3400-3600 MHz na 4800-5000 MHz nk'itsinda rikora rya sisitemu ya 5G. Iyi igenamigambi itanga icyerekezo gisobanutse cyubushakashatsi niterambere no gucuruza ibikoresho bya sisitemu, chip, terminal hamwe nibikoresho byipimisha, kandi biteza imbere ubucuruzi bwa 5G.
Muri make, C-band igira uruhare runini mumiyoboro ya 5G. Ibyiza byayo mugukwirakwiza, umuvuduko wo kohereza, ibikoresho bya spekure hamwe nubufasha bwa tekiniki bituma iba umusingi wingenzi wo kumenya icyerekezo cya 5G. Mugihe gahunda yo kohereza 5G kwisi yose igenda itera imbere, uruhare rwa C-band ruzarushaho kuba ingirakamaro, bizana abakoresha uburambe bwiza bwitumanaho.
