IntangiriroByaCTIA

Ishyirahamwe ry’itumanaho rya Cellular (CTIA) rifite gahunda yo gutanga ibyemezo ikubiyemo selile, bateri, adaptate na host hamwe nibindi bicuruzwa bikoreshwa mubicuruzwa bitumanaho bidafite insinga (nka terefone ngendanwa, mudasobwa zigendanwa). Muri byo, icyemezo cya CTIA kuri selile kirakomeye cyane. Usibye ikizamini cyimikorere rusange yumutekano, CTIA yibanda kandi ku miterere yimiterere ya selile, inzira zingenzi zuburyo bwo gukora no kugenzura ubuziranenge. Nubwo icyemezo cya CTIA atari itegeko, abakora ibikorwa byitumanaho muri Amerika ya ruguru basaba ibicuruzwa byabo kubatanga ibyemezo bya CTIA, kubwibyo icyemezo cya CTIA nacyo gishobora gufatwa nkibisabwa kwinjira ku isoko ry’itumanaho muri Amerika y'Amajyaruguru.

Amavu n'amavuko

Impamyabumenyi ya CTIA yamye yerekeza kuri IEEE 1725 na IEEE 1625 yatangajwe na IEEE (Institute of Electrical and Electronics Engineers). Mbere, IEEE 1725 yakoreshaga kuri bateri idafite urukurikirane; mugihe IEEE 1625 yakoresheje kuri bateri ifite ibice bibiri cyangwa byinshi bihuza. Nkuko porogaramu ya batiri ya CTIA yagiye ikoresha IEEE 1725 nkibipimo ngenderwaho, nyuma yo gutanga verisiyo nshya ya IEEE 1725-2021 muri 2021, CTIA nayo yashizeho itsinda ryakazi ryo gutangiza gahunda yo kuvugurura gahunda yo kwemeza CTIA.

Itsinda ryabakozi ryasabye cyane ibitekerezo bya laboratoire, abakora batiri, abakora terefone ngendanwa, abakora ibicuruzwa, abakora adapter, nibindi. Muri Gicurasi uyu mwaka, habaye inama yambere yumushinga wa CRD (Icyemezo gisaba ibyemezo). Muri icyo gihe, hashyizweho itsinda ryihariye rya adaptori kugirango baganire kuri USB interineti nibindi bibazo bitandukanye. Nyuma yigihe kirenga igice cyumwaka, amahugurwa aheruka yabaye muri uku kwezi. Yemeza ko gahunda nshya yo kwemeza CTIA IEEE 1725 (CRD) izatangwa mu Kuboza, igihe cy’inzibacyuho cy’amezi atandatu. Ibi bivuze ko icyemezo cya CTIA kigomba gukorwa hifashishijwe verisiyo nshya yinyandiko ya CRD nyuma yukwezi kwa 2023.Twe, MCM, nkumunyamuryango wa Laboratwari y’ibizamini bya CTIA (CATL), hamwe n’itsinda ry’abakozi ba CTIA, twasabye ko havugururwa gahunda nshya y’ibizamini kandi twitabira muri CTIA IEEE1725-2021 ibiganiro bya CRD. Ibikurikira nibisubirwamo byingenzi:

Ivugurura nyamukuru

1. Ibisabwa kuri bateri / pack subsystem yongeyeho, ibicuruzwa bigomba kuba byujuje ubuziranenge haba UL 2054 cyangwa UL 62133-2 cyangwa IEC 62133-2 (hamwe no gutandukana kwa Amerika). Birakwiye ko tumenya ko mbere nta mpamvu yo gutanga ibyangombwa byose byo gupakira.
2. Kubizamini bya selile, IEEE 1725-2021 yasibye ikizamini kigufi cyumuzunguruko nyuma ya 25 yubushyuhe buke kandi buke. Nubwo CTIA yamye yerekeza kuri IEEE, amaherezo yahisemo kugumana iki kizamini. Ibi ni ukureba ko imiterere yikizamini ikaze, ariko kuri bamwe basaza, bateri mbi, ikizamini gishobora kumenya imikorere yibikorwa ako kanya. Irerekana kandi icyemezo cya CTIA kugenzura byimazeyo umutekano wutugari.
3. CRD nshya ya CTIA IEEE 1725 ikuraho ibintu byipimishije bijyanye na USB Type B kandi inahindura igipimo cyikigereranyo cya overvoltage kubikoresho byakiriye kuva 9V kugeza 24V kugirango bikurikize USB Type C. Ibi birerekana kandi ko nyuma yigihe cyinzibacyuho kirangiye umwaka utaha, adaptate ya USB Type B ntizaba igishoboye gusaba icyemezo cya CTIA. Ibi kandi byita ku nganda, ubu zikaba ahanini zihindura USB Type B adaptator ya USB Type C.
4. Ingano yo gusaba ibicuruzwa 1725 yaguwe. Hamwe no kongera ubushobozi bwa bateri ya terefone ngendanwa, ubushobozi bwa bateri imwe imwe ntigishobora guhura nigihe kirekire cyo gukoresha terefone ngendanwa. Kubwibyo, IEEE 1725 ibyemezo byubahiriza ibyemezo bya terefone ngendanwa nabyo byagura intera yimiterere ya selile muri bateri.

• Akagari kamwe (1S1P)
• Ingirabuzimafatizo nyinshi zibangikanye (1S nP)
• Urukurikirane 2 ingirabuzimafatizo nyinshi (2S nP)

Ibi byose byavuzwe haruguru birashobora kwemezwa kuri CTIA IEEE 1725, nibindi bikoresho bya batiri bigomba kuba byujuje ibisabwa na CTIA IEEE 1625.

Incamake

Ugereranije na verisiyo ishaje, ibishya ntabwo bihinduka cyane mubintu byikizamini, ariko verisiyo nshya itanga umubare wibisabwa bishya byemeza ibyemezo, bigasobanura neza ibyemezo byibicuruzwa, nibindi. Kandi igice cya adaptori cyahinduwe cyane. Intego yicyemezo cya adapteri ni ukugenzura ubwoko bwimikorere ikoreshwa cyane, kandi USB Type C irarenze kumurongo wingenzi. Ukurikije ibi, CTIA ikoresha USB Type C nkubwoko bwonyine bwa adapt. Kugeza ubu Umuryango w’ubumwe bw’ibihugu by’Uburayi na Koreya yepfo bifite umushinga wo guhuza interineti ya USB, icyemezo CTIA yafashe cyo kureka USB Type B no kwimukira muri USB Type C nacyo gishyiraho urufatiro rushoboka rwa USB rushobora guhuzwa muri Amerika ya ruguru mu gihe kiri imbere.

Byongeye kandi, ibitekerezo byavuzwe haruguru nibisubirwamo nibyo bikubiye mu nama, amabwiriza yanyuma agomba kwerekeza kubisanzwe. Kugeza ubu verisiyo nshya yubuziranenge ntirasohoka kandi biteganijwe ko izasohoka hagati mu Kuboza.
