5.2 GNSS RF & Antenna Design Guideline

Isignali ye-GNSS iyisiginali ebuthakathaka. Uma izinti nemizila kungaklanywanga kahle, kulula ukuphazamisa isignali ye-GNSS, okuholela ekwehleni kokuthola ukuzwela kwe-GNSS, kanye nesikhathi sokuma kwe-GNSS. Ukuze ugweme imiphumela engemihle, lezi zimiso ezilandelayo zizobhekwa ku-GNSS RF Design.
Ukuhlukaniswa phakathi kwe-antenna ye-GNSS nezinye izimpondo kufanele okungenani kube ngu-15dB. Imigqa yesiginali ye-GNSS RF kanye nezingxenye ezihlobene ne-RF kumele zibe kude namasignali anesivinini esikhulu,
amasignali okushintsha amandla, nezinye izimpawu zewashi. I-antenna ye-GNSS kufanele ibe kude nesikrini se-LCD, ikhamera, namanye ama-peripheral. I-antenna ye-GNSS izobekwa eduze nangaphezulu kwempahla kangangokunokwenzeka. Bheka isahluko 6.4 ukuze uthole idizayini yesithenjwa ye-antenna ye-GNSS.

Izinguquko noma ukuguqulwa okungagunyazwanga ngokucacile yinhlangano enesibopho sokuthobelana kungase kuqede umgomo wabasebenzisi bokusebenzisa isisetshenziswa. QAPHELA: Lesi sixhobo sihloliwe futhi kwatholakala ukuthi sithobela imikhawulo yedivayisi yedijithali Yekilasi B, ngokuvumelana nengxenye 15 Yemithetho ye-FCC. Le mikhawulo iklanyelwe ukuhlinzeka ngokuvikeleka okufanele ekuphazanyisweni okuyingozi ekufakweni kwendawo yokuhlala. Lesi sixhobo sikhiqiza ukusetshenziswa futhi singakhipha amandla efrikhwensi yomsakazo futhi, uma singayifaki i-d futhi isetshenziswe ngokuhambisana nemiyalelo, ingabangela ukuphazamiseka okuyingozi ezokuxhumana ngomsakazo. Nokho, asikho isiqinisekiso sokuthi ukuphazamiseka ngeke kwenzeke ekufakweni okuthile. Uma lo mshini udala ukuphazamiseka okuyingozi emsakazweni noma kumabonakude, okunganqunywa ngokucisha futhi kukhanyise okokusebenza, umsebenzisi uyakhuthazwa ukuthi azame ukulungisa lokho kuphazamiseka ngesinyathelo esisodwa noma ngaphezulu kulezi ezilandelayo: · Hlela kabusha noma athuthe kwenye indawo. uthi olutholayo. · Khulisa ukuhlukana phakathi kwemishini nomamukeli. · Xhuma okokusebenza endaweni yokuphuma kuyisekethe ehlukile kuleyo lapho umamukeli axhumeke khona. Xhumana nomthengisi noma uchwepheshe werediyo/TV onolwazi ukuze uthole usizo.

I-Declaration d'exposition aux radiations Izinsizakusebenza zihambisana nemikhawulo yase-Canada yokuvezwa kwemisebe kanye nemvelo engaphenduki. Izisetshenziswa ezisetshenziswayo zifakwa futhi zisetshenziswe ebangeni ubuncane obungama-20cm entre le radiateur et votre corps.
Le divayisi ihloselwe kuphela izihlanganisi ze-OEM ngaphansi kwesimo esilandelayo: Imojula yesidlulisi kungenzeka ingabi nendawo kanye nanoma yimuphi omunye umthumeli noma uthi. Inqobo nje uma isimo esingenhla sihlangatshezwana naye, ukuhlolwa okwengeziwe kokudlulisela ngeke kudingeke. Kodwa-ke, isihlanganisi se-OEM sisenomthwalo wemfanelo wokuhlola umkhiqizo wabo wokugcina nganoma yiziphi izimfuneko zokuthobela ezengeziwe ezidingekayo ngale mojuli efakiwe. I-appareil iyisici esiyingqayizivele se-OEM esihambisana nezimo ezilandelayo: Le module émetteur peut ne pas être coïmplanté avec un autre émetteur ou antenne. Tant que les 1 condition ci-dessus sont izimpendulo, des essais supplémentaires sur l'émetteur ne seront pas necessaires. Toutefois, l'intégrateur OEM est toujours responsable des essais sur son produit final pour toutes exigences de conformité supplémentaires diquis pour ce module installé.
Inothi elibalulekile: Esimeni lapho le mibandela ingakwazi ukuhlangabezwana nayo (isibampnokucushwa okuthile kwekhompuyutha ephathekayo noma indawo ehlanganyelwe nomunye umthumeli), khona-ke ukugunyazwa kwe-Canada akusabhekwa njengokuvumelekile futhi i-IC ayikwazi ukusetshenziswa emkhiqizweni wokugcina. Kulezi zimo, isihlanganisi se-OEM sizoba nesibopho sokuhlola kabusha umkhiqizo wokugcina (okuhlanganisa nesidlulisi) kanye nokuthola ukugunyazwa okuhlukile kwe-Canada. Qaphela Okubalulekile: Izimo ze-Dans le cas où ces ne peuvent être satisfaites (isibonelo uthele ukucushwa okuthile d'ordinateur portable ou de certaines co-localisation avec un autre émetteur), l'autorisation du Canada n'est plus considéré comme valide et l' I-IC ne peut pas être utilisé sur le produit final. Izimo ze-Dans, l'intégrateur OEM sera chargé de réévaluer le produit final (y compris l'émetteur) kanye ne-obtention d'une autorisation distincte noma i-Canada. Qeda Ukulebula Komkhiqizo
Umkhiqizo wokugcina kufanele ulebulwe endaweni ebonakalayo nalokhu okulandelayo: Iqukethe i-IC: 23761-8XRA002. I-Plaque signalétique du produit final Le produit final doit être étiqueté dans un endroit ebonakalayo i-avec l'inscript suivante: I-Cotient des IC: 237618XRA002
Ulwazi Lwemanuwali Kumsebenzisi Wokugcina Umhlanganisi we-OEM kufanele aqaphele ukuthi anganikezi umsebenzisi wokugcina ulwazi mayelana nendlela yokufaka noma ukususa le mojula ye-RF encwadini yomsebenzisi yomkhiqizo wokugcina ehlanganisa le moduli. Imanuwali yomsebenzisi wokugcina izofaka yonke imininingwane edingekayo yokulawula/isexwayiso njengoba kubonisiwe kule manuwali. Manuel d'information à l'utilisateur final L'intégrateur OEM doit être conscient de ne pas fournir des informations à l'utilisateur final à la façon d'installer ou de supprimer ce module RF dans le manuel de l'utilisateur final produit qui integre ce module. I-Le manuel de l'utilisateur doit yokugcina ihlanganisa ama-toutes les informations réglementaires idinga kanye nezimemezelo comme indiqué dans ce manuel.
Isexwayiso: (i) Idivayisi yokusebenza ebhendini engu-5150 MHz ingeyokusetshenziswa endlini kuphela ukunciphisa amandla
ukuphazamiseka okuyingozi kumasistimu esathelayithi ephathwayo esebenzisana namashaneli; (ii) (ii) Kumadivayisi ane(izi)zithi ezikhiphekayo), inzuzo enkulu yothi evunyelwe kumadivayisi akumabhendi.
5250-5350 MHz kanye no-5470-5725 MHz kuzoba ngendlela yokuthi okokusebenza kusahambisana nomkhawulo we-EIRP; (iii) (iii) Kumadivayisi ane(izi)zithi ezikhiphekayo), inzuzo enkulu yothi evunyelwe kumadivayisi ebhendi.
5725-5850 MHz izoba ngendlela yokuthi okokusebenza kusahambisana nemikhawulo ye-EIRP ecaciswe ukusebenza kwe-point-topoint kanye nokungenzi iphuzu-kuya-iphuzu njengoba kufanele; kanye nokuthi Ukusebenza kubhendi engu-5.25-5.35GHz kukhawulelwe ekusetshenzisweni kwangaphakathi kuphela. Ngaphezu kwalokho, ngebhendi yefrikhwensi engu-5600-5650MHz yomsebenzi we-radar yesimo sezulu saseCanada, okokusebenza kunqunyelwe isoftware ukukhawulela umsebenzi wale bhendi yemvamisa, futhi umsebenzisi akakwazi ukushintsha ngokuzimela.
