I-Hearing Aid Compatibility (HAC) ibhekisela ekusebenzisaneni phakathi kweselula nensiza yokuzwa lapho isetshenziswa kanyekanye. Kubantu abaningi abanenkinga yokuzwa, izinsiza-kuzwa ziyimishini ebalulekile ekuphileni kwabo kwansuku zonke. Kodwa-ke, lapho besebenzisa amafoni abo, bavame ukuphazanyiswa yi-electromagnetic, okuholela ekuzweni okungacacile noma umsindo. Ukuze kubhekwane nalolu daba, i-American National Standards Institute (ANSI) ithuthukise amazinga okuhlola afanelekile kanye nezidingo zokuthobelana zokuhambisana kwe-HAC kwezinsiza-kuzwa.
E-United States, abantu abangaphezu kwezigidi ezingu-37.5 banenkinga yokungezwa. Phakathi kwabo, cishe u-25% wabantu abaneminyaka engu-65 kuya ku-74 banenkinga yokuzwa, futhi cishe u-50% wabantu asebekhulile abaneminyaka engu-75 nangaphezulu bahlushwa ukungakwazi ukuzwa. Ukuze kuqinisekiswe ukuthi lezi zihlwele zifinyelela izinsiza zokuxhumana ngokulinganayo futhi ziyakwazi ukusebenzisa omakhalekhukhwini emakethe, i-Federal Communications Commission yase-United States ikhiphe uhlaka ukuze kuboniswane, ihlela ukuthola ukuhambisana kosizo lokuzwa okungu-100%. (HAC) kumaselula.
I-HAC igama lemboni elaqala ukuvela ngasekupheleni kwawo-1970. Enye yezindlela zokusebenza zezinsiza zokuzwa incike kulokhu, okuwukuthi inkambu kazibuthe eshintshanayo yezingxenye zomsindo wefoni izobangela izinsiza-kuzwa ukuthi zikhiqize i-voltage ebangelwe. Lokhu kudale indlela yokuhlola ye-HAC. Ukuhlolwa kwe-HAC kuchaza ijika lempendulo ye-electromagnetic ekhiqizwa izingxenye ezikumakhalekhukhwini. Uma ijika lingangeni ngaphakathi kwebhokisi, libonisa ukuthi ifoni ayibafanele abantu abangezwa kahle.
Maphakathi nawo-1990s, kwatholakala ukuthi isignali yefrikhwensi yomsakazo kumaselula yayinamandla, eyayizovimba isignali enxenxwayo ephakelwa idivayisi yomsindo ensiza yokuzwa. Ngakho-ke, iqembu lamaqembu amathathu (abakhiqizi bezingcingo ezingenazintambo, abakhiqizi bezinsiza zokuzwa, nabantu abangezwa kahle) bahlala ndawonye futhi babhala ngokuhlanganyela futhi benza i-IEEE C63.19, echaza ngokuningiliziwe ukuhlolwa komthelela wamayunithi wefrikhwensi yomsakazo, ukuhlolwa kwe-electromagnetic kumadivayisi angenawaya ( kulokhu, omakhalekhukhwini), njll., okuhlanganisa amasiginali, izincomo zehadiwe, izinyathelo zokuhlola, izintambo, izimiso zokuhlola, njll.
1. Izimfuneko ze-FCC zawo wonke amadivayisi aphethwe ngesandla e-United States:
I-Federal Communications Commission (FCC) e-United States idinga ukuthi kusukela ngomhla ka-5 Disemba 2023, zonke izisetshenziswa zetheminali eziphathwa ngesandla kufanele zihlangabezane nezimfuneko zezinga le-ANSI C63.19-2019 (okungukuthi izinga le-HAC 2019).
Uma kuqhathaniswa nenguqulo yakudala ye-ANSI C63.19-2011 (HAC 2011), umehluko omkhulu phakathi kwakho kokubili usekwengezweni kwezidingo zokuhlolwa kokulawulwa kwevolumu kuzinga le-HAC 2019. Izinto zokuhlola isilawuli sevolumu ikakhulukazi zifaka ukuhlanekezela, impendulo yemvamisa, kanye nokuzuza kweseshini. Izidingo ezifanele nezindlela zokuhlola zidinga ukubhekisa ku-ANSI/TIA-5050-2018 ejwayelekile.
2.Iziphi izinto ezifakwe ekuhlolweni kwe-HAC zokuhambisana nensiza yokuzwa?
Ukuhlolwa kwe-HAC kokuhambisana kwensiza yokuzwa ngokuvamile kuhlanganisa ukuhlolwa kwe-RF Rating kanye nokuhlolwa kwe-T-Coil. Lezi zivivinyo zihlose ukuhlola izinga lokugxambukela kwamaselula ezinsizeni zokuzwa ukuze kuqinisekiswe ukuthi abasebenzisi bokuzwa bangathola umuzwa ocacile nongaphazamisi wokuzwa lapho bephendula izingcingo noma besebenzisa ezinye izisetshenziswa zomsindo.
Isitifiketi se-FCC
Ngokwezidingo zakamuva ze-ANSI C63.19-2019, izimfuneko Zokulawulwa Kwevolumu zengeziwe. Lokhu kusho ukuthi abakhiqizi kudingeka baqinisekise ukuthi ifoni ihlinzeka ngokulawula kwevolumu okufanele ngaphakathi kwebanga lokuzwa labasebenzisi bokusiza ukuzwa ukuze baqinisekise ukuthi bayakwazi ukuzwa imisindo yezingcingo ecacile. Izidingo zikazwelonke zamazinga okuhlola we-HAC:
I-United States (FCC): I-FCC eCR Ingxenye 20.19 HAC
I-Canada (IED): RSS-HAC
I-China: YD/T 1643-2015
3.Ngomhla ziyi-17 kuMbasa, 2024, isemina ye-TCB yabuyekeza izidingo ze-HAC:
1)Idivayisi idinga ukugcina amandla okudlulisela aphezulu kakhulu kumodi yendlebe ukuya endlebeni.
2)I-U-NII-5 idinga ukuhlola ibhendi yefrikhwensi eyodwa noma amaningi ku-5.925GHz-6GHz.
3)Isiqondiso sesikhashana sebhendi yefrikhwensi ye-5GNR FR1 ku-KDB 285076 D03 sizosuswa phakathi kwezinsuku ezingu-90; Ngemuva kokususwa, kuyadingeka ukusebenzisana nesiteshi sesisekelo (esidinga ukusekela umsebenzi we-VONR) ukuze kuhlolwe ukufakazela ukuthobela kwe-HAC kwe-5GNR, okuhlanganisa nezidingo zokulawula ivolumu.
4) Zonke izingcingo ze-HAC zidinga ukumemezela futhi zisebenzise i-Waiver PAG ngokuhambisana nedokhumenti yokukhululwa Waiver DA 23-914.
Ilebhu yokuhlola ye-BTF, inkampani yethu inamalabhorethri ahambisana nogesi, izimiso zokuphepha Ilabhorethri, Ilabhorethri yefrikhwensi yomsakazo, Ilabhorethri yebhethri, Ilabhorethri yamakhemikhali, I-SAR Laboratory, I-HAC Laboratory, njll. Sithole iziqu nokugunyazwa okufana ne-CMA, CNAS, CPSC, A2LA, I-VCCI, njll. Inkampani yethu inethimba lobunjiniyela bezobuchwepheshe abanolwazi nochwepheshe, elingasiza amabhizinisi ukuxazulula inkinga. Uma unezidingo ezifanele zokuhlola nezitifiketi, ungathintana ngqo nabasebenzi bethu bokuhlola ukuze uthole amakhotheshini anemininingwane yezindleko kanye nolwazi lomjikelezo!
