Spectrum ya 6GHz, ahazaza ha 5G

Gutanga Spectrum ya 6GHz byarangiye

Inama ya WRC-23 (Inama Mpuzamahanga y’Itumanaho rya Radiyo 2023) iherutse gusozwa i Dubai, yateguwe n’Ishyirahamwe Mpuzamahanga ry’Itumanaho (ITU), igamije guhuza ikoreshwa ry’urusobe rw’amashanyarazi ku isi.

Kuba ikoranabuhanga rya 6GHz ryari iry’ingenzi cyane ku isi yose.

Inama yemeje: Gutanga umurongo wa 6.425-7.125GHz (umuyoboro wa 700MHz) kuri serivisi za telefoni zigendanwa, cyane cyane ku itumanaho rya telefoni zigendanwa rya 5G.

6GHz ni iki?

6GHz yerekeza ku rugero rwa spectrum kuva kuri 5.925GHz kugeza kuri 7.125GHz, hamwe n'umuyoboro w'itumanaho ugera kuri 1.2GHz. Mbere, spectrum ya frequency yo hagati kugeza kuri low yagenewe itumanaho rya telefoni igendanwa yari isanzwe ikoreshwa, ariko ikoreshwa rya spectrum ya 6GHz gusa ntiryari risobanutse neza. Ingano ntarengwa ya mbere ya Sub-6GHz kuri 5G yari 6GHz, hejuru yayo hakaba hari mmWave. Hamwe n'igihe cy'ubuzima cya 5G cyitezweho ndetse n'amahirwe mabi y'ubucuruzi kuri mmWave, gushyiramo 6GHz ku mugaragaro ni ingenzi cyane ku cyiciro gikurikira cy'iterambere rya 5G.

3GPP yamaze gushyiraho uburyo bwo gupima igice cyo hejuru cya 6GHz, cyane cyane 6.425-7.125MHz cyangwa 700MHz, muri Release 17, izwi kandi nka U6G ifite frequence band yitwa n104.

Wi-Fi nayo yagiye ihatanira 6GHz. Hamwe na Wi-Fi 6E, 6GHz yashyizwe muri ubu buryo busanzwe. Nkuko bigaragara hano hasi, hamwe na 6GHz, imiyoboro ya Wi-Fi izava kuri 600MHz muri 2.4GHz na 5GHz ikagera kuri 1.8GHz, naho 6GHz izashyigikira bandwidth ya 320MHz kuri carrier imwe muri Wi-Fi.

Raporo yakozwe n’ishyirahamwe rya Wi-Fi ivuga ko Wi-Fi muri iki gihe itanga ubushobozi bwinshi bwa network, bigatuma 6GHz iba ejo hazaza ha Wi-Fi. Ibisabwa n’itumanaho rya telefoni zigendanwa kuri 6GHz ntibishoboka kuko hari byinshi bitarakoreshwa.

Mu myaka ya vuba aha, habayeho ibitekerezo bitatu ku bijyanye n'umutungo wa 6GHz: Icya mbere, kuyishyira ku murongo wa Wi-Fi. Icya kabiri, kuyishyira ku murongo wa telefoni zigendanwa (5G). Icya gatatu, kuyigabanya ku buryo bungana hagati y’ibyo byombi.

Nkuko bigaragara ku rubuga rwa interineti rwa Wi-Fi Alliance, ibihugu byo muri Amerika byiganjemo 6GHz yose kuri Wi-Fi, mu gihe i Burayi byo byiganjemo gushyira igice cyo hasi kuri Wi-Fi. Birumvikana ko igice cyo hejuru gisigaye kijya kuri 5G.

Icyemezo cya WRC-23 gishobora gufatwa nk'icyemeza ubwumvikane busanzwe, bugatuma habaho inyungu hagati ya 5G na Wi-Fi binyuze mu ipiganwa n'ubwumvikane hagati y'ibihugu byombi.

Nubwo iki cyemezo gishobora kutagira ingaruka ku isoko rya Amerika, ntibibuza ko 6GHz iba umuyoboro wagutse ku isi yose. Byongeye kandi, kuba uyu muyoboro ari muto bituma kugera ku muyoboro wo hanze bisa na 3.5GHz bitagorana cyane. 5G izazana umuvuduko wa kabiri w’inyubako.

Dukurikije ibyari biteganijwe na GSMA, iyi gahunda itaha yo kubaka 5G izatangira mu 2025, ikaba ari igice cya kabiri cya 5G: 5G-A. Dutegereje ibitangaza 5G-A izazana.

Concept Microwave ni uruganda rw'umwuga rukora ibice bya 5G/6G RF mu Bushinwa, birimo RF lowpass filter, highpass filter, bandpass filter, notch filter/band stop filter, duplexer, Power divider na directional coupler. Byose bishobora guhindurwa hakurikijwe ibyo ukeneye.
