Ukuhlola okwengeziwe, Ingxenye 15 Umshwana Wokuzikhipha Emthwalweni Wengxenye Engaphansi B Umsingathi wokugcina/inhlanganisela yemojula idinga ukubuyekezwa ngokuqhathanisa nemibandela ye-FCC Ingxenye 15B ukuze amarediyetha angahlosiwe agunyazwe ngokufanelekile ukuthi asebenze njengedivayisi yedijithali Ingxenye 15.

Umhlanganisi womsingathi ofaka le mojula emkhiqizweni wakhe kufanele aqinisekise ukuthi umkhiqizo wokugcina oyinhlanganisela uthobela izimfuneko ze-FCC ngokuhlolwa kobuchwepheshe noma ukuhlola imithetho ye-FCC, okuhlanganisa nokusebenza komthumeli futhi kufanele abhekisele kumhlahlandlela ku-KDB 996369. Ngemikhiqizo yomsingathi ene-FCC ama-modular transmitters aqinisekisiwe, ububanzi bemvamisa yophenyo lwesistimu eyinhlanganisela bucaciswa umthetho oseSigabeni 15.33(a)(1) ukuya ku-(a)(3), noma ububanzi obusebenza kudivayisi yedijithali, njengoba kuboniswe kuSigaba 15.33(b) )(1), kungakhathaliseki ukuthi yiliphi ibanga eliphakeme lefrikhwensi yophenyo Lapho kuhlolwa umkhiqizo wokusingatha, wonke ama-transmitter kufanele asebenze. Ama-transmitter angavulwa ngokusebenzisa izishayeli ezitholakala esidlangalaleni futhi avuliwe, ngakho-ke ama-transmitter ayasebenza. Ezimweni ezithile, kungase kube okufanelekile ukusebenzisa ibhokisi lekholi eliqondene nobuchwepheshe (isethi yokuhlola) lapho izisetshenziswa ze-50 noma izishayeli zingatholakali. Lapho kuhlolwa ukukhishwa okuvela kurediyetha ngokungahlosiwe, isidlulisi sizobekwa kumodi yokwamukela noma imodi yokungenzi lutho, uma kungenzeka. Uma imodi yokwamukela kuphela ingenzeki, umsakazo uzoba yi- passive (okukhethwa kukho) kanye/noma ukuskena okusebenzayo. Kulezi zimo, lokhu kuzodinga ukunika amandla umsebenzi ku-BUS yokuxhumana (okungukuthi, i-PCIe, i-SDIO, i-USB) ukuze kuqinisekiswe ukujikeleza kwerediyetha okungahlosiwe kuvuliwe. Amalabhorethri ahlolayo angase adinge ukwengeza ukuncipha noma izihlungi kuye ngamandla esignali anoma imaphi amabhakhoni asebenzayo (uma ekhona) asuka kumarediyo anikwe amandla. Bheka i-ANSI C63.4, ANSI C63.10 kanye ne-ANSI C63.26 ukuze uthole imininingwane eyengeziwe yokuhlola okuvamile.

Umkhiqizo ongaphansi kokuhlolwa usethelwe kusixhumanisi/inhlangano nedivayisi ebambisene, njengokujwayelekile ukusetshenziswa okuhlosiwe komkhiqizo. Ukuze wenze ukuhlolwa kube lula, umkhiqizo ongaphansi kokuhlolwa usethelwe ukudlulisa ngomjikelezo wemisebenzi ephezulu, njengokuthumela file noma ukusakaza okunye okuqukethwe kwemidiya.

Isexwayiso se-FCC:
Noma yiziphi Izinguquko noma ukuguqulwa okungagunyazwanga ngokucacile yinhlangano enesibopho sokuthobela imithetho kungasusa igunya lomsebenzisi lokusebenzisa okokusebenza. Le divayisi ithobela ingxenye 15 yeMithetho ye-FCC. Ukusebenza kungaphansi kwezimo ezimbili ezilandelayo: (1) Lolu cingo angeke lubangele ukuphazamiseka okuyingozi, futhi (2) Lolu cingo kufanele lwamukele noma yikuphi ukuphazamiseka okutholiwe, okuhlanganisa ukuphazamiseka okungase kubangele ukusebenza okungafuneki.
