▍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 okuhambisanayo 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.

Ngomhla zingama-25 kuJuni 2021, iwebhusayithi esemthethweni ye-UL yakhipha isiphakamiso sakamuva sokuchitshiyelwa kuzinga le-UL2054. Ukucelwa kwemibono kuqhubeka kuze kube umhla ziyi-19 kuJulayi, 2021. Okulandelayo yizinto ezichitshiyelwe ezingu-6 kulesi siphakamiso:
1. Ukufakwa kwezidingo ezijwayelekile zesakhiwo sezintambo namatheminali: ukufakwa kwezintambo kufanele kuhlangabezane nezidingo ze-UL 758;
2. Izichibiyelo ezixubile kuzinga: ikakhulukazi ukulungiswa kokungapeli kahle, ukubuyekezwa kwamazinga acashuniwe;
3. Ukwengezwa kwezidingo zokuhlola zokunamathela: ukuhlolwa kokusula ngamanzi nezinyibilikisi eziphilayo;
4. Ukwenyuswa kwezindlela zokuphatha zezingxenye namasekhethi anomsebenzi wokuvikela ofanayo ekuhlolweni kokusebenza kukagesi: Uma izingxenye ezimbili ezifanayo noma amasekhethi esebenza ndawonye ukuze avikele ibhethri, lapho kucatshangwa iphutha elilodwa, izingxenye ezimbili noma amasekhethi kufanele abe nephutha ngesikhathi esifanayo.
5. Ukumaka ukuhlolwa kokunikezwa kwamandla okulinganiselwe njengokuzithandela: ukuthi ukuhlolwa kokunikezwa kwamandla okulinganiselwe eSahlukweni 13 sezinga kuyenziwa yini kuzonqunywa ngokuya ngezidingo zomkhiqizi. Ukuguqulwa kwesigatshana se-9.11 - ukuhlolwa kwesifunda esifushane sangaphandle: izinga lokuqala ukusebenzisa i-16AWG (1.3mm2) i-Bare Copper Wire; isiphakamiso sokuguqulwa: ukumelana kwangaphandle kwesekethe emfushane kufanele kube ngocingo lwethusi olungenalutho oluyi-80±20mΩ.
