uniview I-WF-M63B-USH1 Incwadi Yomsebenzisi Yemojuli
Isingeniso se-1
Idizayini yemojuli ye-WF-M63B-USH1 isuselwe kusixazululo se-Mediatek MT7663BUN, I-MT7663BUN iyi-chip eyodwa edidiyelwe kakhulu eyakhelwe umsakazo we-LAN ongenantambo we-2 × 2 kanye nomsakazo we-Bluetooth. Ihlanganisa i-Bluetooth EDR kanye nomsakazo we-LE ohambisana ne-Bluetooth v2.1+EDR, v4.2, kanye ne-v5.1.
I-Module iyi-MAC/BBP edidiyelwe kakhulu kanye ne-2.4/5GHz PA/LNA chip eyodwa esekela izinga le-PHY elingu-866.7Mbps. Imojula yakhelwe ukusekela izici ezisekelwe ezingeni ezindaweni zokuvikela, ikhwalithi yesevisi, nemithetho yamazwe ngamazwe, enikeza abasebenzisi bokugcina ukusebenza okuhle kakhulu nganoma yisiphi isikhathi nanoma yisiphi isimo. Lo mbhalo uchaza ukucaciswa kwezidingo zobunjiniyela.
1.1 Imojuli ye-RF Overview
Isakhiwo esijwayelekile se-HW semojuli sikhonjisiwe kuMfanekiso 1. Lo mklamo we-WLAN Module usekelwe ku-Mediatek MT7663BUN. Isilawuli senethiwekhi ye-single-chip ye-MIMO(Multiple In Multiple Out) Wireless LAN (WLAN) ehlanganiswe kakhulu ethobelana nokucaciswa kwe-802.11 kanye ne-Bluetooth phezu kokusebenzelana kwe-USB. Ihlanganisa i-MAC, i-baseband enekhono engu-2T2R, ne-RF ku-chip eyodwa. I-algorithm ehlakaniphile ye-Wi-Fi/Bluetooth ye-coexistence algorithm isetshenziswa ukuze kuhlinzekwe ukusebenza kahle kwe-Wi-Fi evumelanisiwe nokusebenza komsakazo we-Bluetooth.

Isitatimende se-FCC:
Uyacelwa ukuthi unake ukuthi ushintsho noma ukuguqulwa okungavunyelwanga ngokusobala yilowo obhekene nokuhambisana nakho kungenza igunya lomsebenzisi lisebenze okokusebenza.
Le divayisi ihambisana nengxenye 15 yemithetho ye-FCC. Umsebenzi ungaphansi kwale mibandela emibili elandelayo:
- Le divayisi kungenzeka ingabangeli ukuphazamiseka okuyingozi, futhi
- Le divayisi kufanele yamukele noma yikuphi ukuphazamiseka okutholakele, kufaka phakathi ukuphazamiseka okungadala ukungafuneki
Le mishini ihambisana nemikhawulo yokuvezwa kwemisebe yeCCC ebekelwe imvelo engalawulwa. Le mishini kufanele ifakwe futhi isebenze ngebanga elincane elingu-20cm phakathi kwe-radiator nomzimba wakho.
(1) Izimo zokusebenzisa ukusebenza
Imojula inabasebenzisi abangochwepheshe bemibandela yokusebenzisa imikhawulo yemibandela, umenzi womkhiqizo ongumsingathi sicela uqinisekise ukunikeza isixwayiso esifana nokuthi “Umkhiqizo ukhawulelwe ukusetshenziswa kwabasebenzisi abangochwepheshe” emyalelweni womkhiqizo wakho.

(3) Umyalelo Wokulebula Wesihlanganisi Somkhiqizo Wosokhaya
Sicela uqaphele ukuthi uma inombolo kamazisi ye-FCC ingabonakali lapho imojuli ifakwe phakathi kwenye idivayisi, khona-ke ingaphandle ledivayisi lapho imojuli efakwe kuyo kufanele futhi ibonise ilebula ebhekisela kumojula evaliwe. Ku-FCC, le lebula yangaphandle kufanele ilandele “Iqukethe i-FCC ID: 2AL8S-0302C3XN-1”. Ngokuhambisana nesiqondiso se-FCC KDB 784748 Izinkombandlela Zokulebula.
15.19 kanye nezidingo Zokulebula ze-RSS-Gen zizolandelwa kudivayisi yomsebenzisi wokugcina. Imithetho yokulebula yedivayisi ekhethekile, sicela ubhekisele ku-§2.925, § 15.19 (a) (5) nokushicilelwe kwe-KDB okuhlobene. Ngelebula ye-E, sicela ubhekisele ku-§2.935.
(4) Isaziso Sokufaka Sokusingatha Umkhiqizi Womkhiqizo
Isihlanganisi se-OEM sinesibopho sokuqinisekisa ukuthi umsebenzisi wokugcina akanawo umyalo owenziwe ngesandla wokususa noma ukufaka imojula.
Imojula ikhawulelwe ekufakweni kuhlelo lokusebenza lweselula, imvume ehlukile iyadingeka kukho konke okunye ukulungiselelwa kokusebenza, okuhlanganisa ukucushwa okuphathekayo ngokuphathelene ne-§2.1093 kanye nokuhlelwa komehluko we-antenna.
(5) Isaziso sokushintsha i-antenna kumkhiqizi ongusokhaya
Uma ufisa ukukhulisa inzuzo ye-antenna futhi uguqule uhlobo lwe-antenna noma usebenzise uhlobo olufanayo lwe-antenna eqinisekisiwe, isicelo sokushintsha imvume ye-Class II siyadingeka ukuthi filed yithi, noma wena (umkhiqizi ophethe) ungathatha isibopho ngoshintsho ku-FCC ID kanye nenqubo ye-IC ID (uhlelo olusha lohlelo lokusebenza) olulandelwa yi-Class II yesicelo soshintsho lwemvume.
(6) Ezinye Izingxenye ze-FCC, Ingxenye 15B Izidingo Zokuthobelana kumkhiqizi Wosokhaya womkhiqizo
Lesi sidlulisi esiyimojuli sigunyazwe yi-FCC kuphela yezingxenye ezithile zemithetho ezisohlwini lwesibonelelo sethu, umenzi womkhiqizo osingethe unesibopho sokuthobela noma yimiphi eminye imithetho ye-FCC esebenza kumsingathi ongafakwanga yi-modular transmitter grant yomkhiqizi Wokusingatha kunoma isiphi isimo uzoqinisekisa umsingathi. umkhiqizo ofakiwe futhi osebenza ngemojula uhambisana nezimfuneko zeNgxenye 15B.
Sicela uqaphele ukuthi Okwekilasi B noma idivayisi yedijithali yekilasi A, imiyalelo enikezwe imanuwali yomsebenzisi womkhiqizo izofaka isitatimende esibekwe ku-§15.105 Ulwazi oluya kumsebenzisi noma isitatimende esifanayo bese usibeka endaweni evelele. embhalweni wemanuwali yomkhiqizo womsingathi. Imibhalo yokuqala kanjena:
Okwekilasi B
Qaphela: Lo mshini uhloliwe kwatholakala ukuthi uhambisana nemikhawulo yedivayisi yedijithali yeClass B, ngokuya ngengxenye 15 yeMithetho yeCCC. Le mikhawulo yakhelwe ukuhlinzeka ngokuvikelwa okufanele ekuphazanyisweni okuyingozi ekufakweni kwendawo yokuhlala. Le mishini ikhiqiza, isebenzise futhi ingakhipha amandla amaza omsakazo futhi, uma ingafakiwe futhi isetshenziswe ngokuyalelwa, ingadala ukuphazamiseka okuyingozi ekuxhumaneni nomsakazo. Kodwa-ke, asikho isiqinisekiso sokuthi ukuphazamiseka ngeke kwenzeke ekufakweni okuthile. Uma lo mshini ubangela ukuphazamiseka okuyingozi emsakazweni noma ekwamukelweni kwethelevishini, okunganqunywa ngokucisha nokuvula imishini, umsebenzisi uyakhuthazwa ukuthi azame ukulungisa ukuphazamiseka ngenye yezinyathelo ezilandelayo:
-Buyisela kabusha noma ususe i-antenna yokuthola
-Khulisa ukwehlukana phakathi kwensiza nesamukeli.
—Xhuma okokusebenza endaweni oyisebenzisayo esiteshini esihlukile kunaleso okuxhunywe kuso umamukeli.
-Thola usizo kumthengisi noma uchwepheshe onomsakazo / we-TV onolwazi.
Okwekilasi A
Qaphela: Lo mshini uhloliwe kwatholakala ukuthi uhambisana nemikhawulo yedivayisi yedijithali yeClass A, ngokuya ngengxenye 15 yeMithetho yeCCC. Le mikhawulo yakhelwe ukuhlinzeka ngokuvikelwa okufanele ekuphazanyisweni okuyingozi lapho okokusebenza kusetshenziswa endaweni yezentengiselwano. Le mishini ikhiqiza, isebenzise, futhi ingakhipha amandla amaza omsakazo futhi, uma ingafakiwe futhi isetshenziswe ngokuya ngencwajana yokufunda, ingadala ukuphazamiseka okuyingozi ekuxhumaneni nomsakazo. Ukusebenza kwale mishini endaweni ehlala abantu kungenzeka kudale ukuphazamiseka okuyingozi lapho umsebenzisi kuzodingeka ukuthi alungise lokho kuphazamiseka ngezindleko zakhe.
