Isitifiketi sokusebenzelana kwe-USB-B sizoqedwa enguqulweni entsha yeI-CTIA IEEE 1725,
I-CTIA IEEE 1725,

▍Iyini I-CTIA CERTIFICATION?

I-CTIA, isifinyezo se-Cellular Telecommunications and Internet Association, yinhlangano yomphakathi engenzi nzuzo eyasungulwa ngo-1984 ngenjongo yokuqinisekisa ukuhlomula kwabaqhubi, abakhiqizi nabasebenzisi. I-CTIA iqukethe bonke opharetha base-US nabakhiqizi abavela kumasevisi omsakazo weselula, kanye namasevisi edatha angenantambo nemikhiqizo. Isekelwe yi-FCC (Federal Communications Commission) kanye neCongress, i-CTIA yenza ingxenye enkulu yemisebenzi nemisebenzi eyayisetshenziselwa ukwenziwa uhulumeni. Ngo-1991, i-CTIA yakha uhlelo lokuhlola lomkhiqizo olungachemile, oluzimele nolwendawo eyodwa kanye nesitifiketi somkhakha ongenazintambo. Ngaphansi kwesistimu, yonke imikhiqizo engenantambo esebangeni labathengi izothatha izivivinyo zokuthobela imithetho futhi leyo ethobelana namazinga afanele izovunyelwa ukusebenzisa ukumaka kwe-CTIA nokushayisana kwamashalofu ezitolo emakethe yezokuxhumana yaseNyakatho Melika.

I-CATL (CTIA Authorized Testing Laboratory) imele amalebhu agunyazwe yi-CTIA ukuze ahlolwe futhi abuyekezwe. Imibiko yokuhlola ekhishwe ku-CATL izogunyazwa yonke yi-CTIA. Nakuba eminye imibiko yokuhlola kanye nemiphumela evela ku-non-CATL ngeke ibonwe noma ingakwazi ukufinyelela ku-CTIA. I-CATL egunyazwe yi-CTIA iyahlukahluka ezimbonini nasekutholeni izitifiketi. I-CATL kuphela efanelekela ukuhlolwa nokuhlolwa kokuthobela ibhethri ekwazi ukufinyelela esitifiketini sebhethri ukuze ihambisane ne-IEEE1725.

▍CTIA Amazinga Wokuhlola Ibhethri

a) Isidingo Sokuthola Isitifiketi Sohlelo Lwebhethri Ukuthobela IEEE1725— Kusebenza Ezinhlelweni Zebhethri ezineseli elilodwa noma amaseli amaningi axhunywe ngokuhambisana;

b) Isidingo Sokuthola Isitifiketi Sohlelo Lwebhethri Ukuthobelana ne-IEEE1625— Kusebenza Ezinhlelweni Zebhethri ezinamaseli amaningi axhunywe ngokuhambisana noma kokubili ngokuhambisana nochungechunge;

Amathiphu afudumele: Khetha ngenhla kwamazinga wesitifiketi ngokufanelekile kumabhethri asetshenziswa omakhalekhukhwini namakhompyutha. Ungasebenzisi kabi i-IEE1725 kumabhethri kumakhalekhukhwini noma i-IEEE1625 kumabhethri akukhompyutha.

▍Kungani i-MCM?

●Ubuchwepheshe obuqinile:Kusukela ngo-2014, i-MCM ibihambela inkomfa yamaphakethe webhethri ebanjwa yi-CTIA e-US minyaka yonke, futhi iyakwazi ukuthola isibuyekezo sakamuva futhi iqonde amathrendi enqubomgomo emisha mayelana ne-CTIA ngendlela esheshayo, enembayo nesebenzayo.

●Ukufaneleka:I-MCM iyi-CATL egunyazwe yi-CTIA futhi ifaneleka ukwenza zonke izinqubo ezihlobene nesitifiketi okuhlanganisa ukuhlola, ukuhlola kwasefekthri nokulayisha umbiko.

I-Cellular Telecommunications Industry Association (CTIA) inohlelo lwesitifiketi olumboza amaseli, amabhethri, ama-adaptha nabasingathi kanye neminye imikhiqizo esetshenziswa emikhiqizweni yokuxhumana engenantambo (njengamaselula, amakhompyutha aphathekayo). Phakathi kwazo, isitifiketi se-CTIA samaseli siqinile kakhulu. Ngaphandle kokuhlolwa kokusebenza kokuphepha okuvamile, i-CTIA iphinde igxile ekwakhiweni kwesakhiwo samaseli, izinqubo ezibalulekile zenqubo yokukhiqiza nokulawula ikhwalithi yayo. Nakuba isitifiketi se-CTIA singaphoqelekile, opharetha bezokuxhumana abakhulu eNyakatho Melika badinga ukuthi imikhiqizo yabahlinzeki babo iphumelele isitifiketi se-CTIA, ngakho-ke isitifiketi se-CTIA singabhekwa njengemfuneko yokungena emakethe yezokuxhumana yaseNyakatho Melika.Izinga lesitifiketi se-CTIA belilokhu libhekisela ku-IEEE 1725 kanye ne-IEEE 1625 eshicilelwe yi-IEEE (Institute of Electrical and Electronics Engineers). Ngaphambilini, i-IEEE 1725 yayisetshenziswa kumabhethri ngaphandle kwesakhiwo sochungechunge; kuyilapho i-IEEE 1625 isetshenziswa kumabhethri anokuxhumana okubili noma ngaphezulu kochungechunge. Njengoba uhlelo lwesitifiketi sebhethri le-CTIA belusebenzisa i-IEEE 1725 njengezinga lokubhekisela, ngemva kokukhishwa kwenguqulo entsha ye-IEEE 1725-2021 ngo-2021, i-CTIA iphinde yakhe iqembu elisebenzayo ukuze liqale uhlelo lokubuyekeza uhlelo lwesitifiketi se-CTIA.Iqembu elisebenzayo kakhulu kucelwe imibono kumalabhorethri, abakhiqizi bebhethri, abakhiqizi bamaselula, abakhiqizi abasingatha, abakhiqizi be-adaptha, njll. NgoMeyi walo nyaka, umhlangano wokuqala wohlaka lwe-CRD (Certification Requirements Document) wabanjwa. Phakathi naleso sikhathi, kwamiswa iqembu le-adaptha elikhethekile ukuze lixoxe ngesixhumi esibonakalayo se-USB nezinye izindaba ngokwehlukana. Ngemva kwesikhathi esingaphezu kwesigamu sonyaka, umhlangano wokugcina wenziwa kule nyanga. Iqinisekisa ukuthi uhlelo olusha lwesitifiketi lweI-CTIA IEEE 1725(CRD) izokhishwa ngoZibandlela, kanye nesikhathi soshintsho esiyizinyanga eziyisithupha. Lokhu kusho ukuthi ukuqinisekiswa kwe-CTIA kufanele kwenziwe kusetshenziswa inguqulo entsha yombhalo we-CRD ngemva kukaJuni 2023. Thina, i-MCM, njengelungu Le-CTIA's Test Laboratory (CATL), kanye ne-CTIA's Battery Working Group, siphakamise izibuyekezo zohlelo olusha lokuhlola futhi sahlanganyela. kuzo zonke izingxoxo ze-CTIA IEEE1725-2021 CRD. Okulandelayo yizibuyekezo ezibalulekile:
