Uruhare rw'ingenzi rwa C-band mu miyoboro ya 5G n'akamaro kayo

C-band, radiyo ifite umurongo wa radiyo uri hagati ya 3.4 GHz na 4.2 GHz, igira uruhare runini mu miyoboro ya 5G. Imiterere yayo yihariye ituma igera kuri serivisi za 5G zihuta cyane, zitinda cyane, kandi zikwirakwizwa mu buryo bwagutse.

1. Uburyo bwo gukwirakwiza amakuru buringaniye n'umuvuduko wo kohereza amakuru

Itsinda rya C-band riri mu gice cyo hagati cy’umuvuduko w’itumanaho, gishobora gutanga uburinganire bwiza hagati yo gukwirakwiza amakuru n’umuvuduko wo kohereza amakuru. Ugereranyije n’itsinda rito, itsinda rya C-band rishobora gutanga uburinganire bwiza hagati yo kohereza amakuru; kandi ugereranije n’itsinda rifite frequency nyinshi (nk’imiraba ya milimetero), itsinda rya C-band rifite uburebure bwagutse. Ubu buryo butuma itsinda rya C-band rikwiriye cyane gukoresha imiyoboro ya 5G mu mijyi no mu nkengero z’umujyi, bigatuma abakoresha babona itumanaho ryihuse mu gihe bigabanya umubare w’aho bashyira amakuru.

2. Umutungo mwinshi wa spectrum

C-band itanga uburyo bwagutse bwo gukoresha ikoranabuhanga kugira ngo ifashe ubushobozi bwo gukoresha amakuru menshi. Urugero, Komisiyo Ishinzwe Itumanaho muri Leta Zunze Ubumwe za Amerika (FCC) yageneye 280 MHz ya mid-band spectrum kuri 5G muri C-band, irayigurisha mu mpera za 2020. Abakora nka Verizon na AT&T babonye ingano nini ya spectrum muri iki cyamunara, bitanga ishingiro rikomeye rya serivisi zabo za 5G.

3. Gushyigikira ikoranabuhanga rigezweho rya 5G

Imiterere y'inshuro C-band ifasha gushyigikira neza ikoranabuhanga ry'ingenzi mu miyoboro ya 5G, nka MIMO nini (multiple-input multiple-output) na beamforming. Iri koranabuhanga rishobora kunoza imikorere ya spectrum, kongera ubushobozi bwa network, no kunoza ubunararibonye bw'abakoresha. Byongeye kandi, inyungu ya bandwidth ya C-band ituma ihura n'ibisabwa mu muvuduko wo hejuru no mu gihe gito cyo gutinda kwa porogaramu za 5G zizaza, nka augmented reality (AR), virtual reality (VR), na Internet of Things (IoT).

4. Gukoreshwa ku isi hose

Ibihugu byinshi n'uturere byinshi byakoresheje C-band nk'umurongo mukuru w'itumanaho rya 5G. Urugero, ibihugu byinshi byo mu Burayi na Aziya bikoresha umurongo wa n78 (3.3 kugeza 3.8 GHz), mu gihe Leta Zunze Ubumwe za Amerika zikoresha umurongo wa n77 (3.3 kugeza 4.2 GHz). Uku guhuza kw'isi yose bifasha mu gushyiraho urusobe rw'ikoranabuhanga rya 5G, guteza imbere imikoranire y'ibikoresho n'ikoranabuhanga, no kwihutisha gukurura no gukoresha 5G.

5. Kwamamaza ikwirakwizwa rya 5G mu bucuruzi

Igenamigambi risobanutse n'igabanywa rya spectrum ya C-band byihutishije ikwirakwizwa ry'imiyoboro ya 5G mu bucuruzi. Mu Bushinwa, Minisiteri y'Inganda n'Ikoranabuhanga mu Itangazamakuru yagennye neza ko imiyoboro ya 3300-3400 MHz (ikoreshwa mu nzu mu buryo bw'ibanze), imiyoboro ya 3400-3600 MHz na 4800-5000 MHz nk'imiyoboro ikora ya sisitemu za 5G. Iyi gahunda itanga icyerekezo gisobanutse cy'ubushakashatsi n'iterambere n'ubucuruzi bw'ibikoresho bya sisitemu, utumashini, ibyuma bipima n'ibikoresho byo gupima, kandi iteza imbere ubucuruzi bwa 5G.

Muri make, C-band ifite uruhare runini mu miyoboro ya 5G. Ibyiza byayo mu gukwirakwiza amakuru, umuvuduko wo kohereza amakuru, umutungo wa spectrum n'ubufasha bwa tekiniki bituma iba ishingiro ry'ingenzi ryo gushyira mu bikorwa icyerekezo cya 5G. Uko ikwirakwizwa rya 5G ku isi rigenda ritera imbere, uruhare rwa C-band ruzarushaho kuba ingenzi, ruhe abakoresha uburyo bwiza bwo gutumanaho.
