OEM IsiKhokelo
- Imigaqo yeFCC esebenzayo
Le modyuli inikwe iMvume yeModyuli eNye. Ihambelana neemfuno zeFCC inxalenye ye-15C, icandelo le-15.247 imithetho. - Iimeko ezikhethekileyo zokusetyenziswa
Le modyuli ingasetyenziswa kwizixhobo zeRF. Igalelo voltage kwimodyuli 3. 0V-3.6 V DC. Ubushushu obusebenzayo bemodyuli bu-40 ukuya kuma-85 degrees C. - Iinkqubo zemodyuli ezilinganiselwe
N / A - Landela uyilo lwe-eriyali
N / A - Iingqwalaselo zokuvezwa kweRF
Isixhobo sithobela imida yeFCC yokuvezwa ngemitha emiselwe indawo engalawulekiyo. Esi sixhobo kufuneka sifakwe kwaye sisebenze kumgama ongaphantsi kwama-20cm phakathi kweradiyetha kunye nomzimba wakho. Ukuba isixhobo sakhelwe kwinginginya ukuze sisetyenziswe ephathekayo, uvavanyo olongezelelweyo lokuvezwa kweRF lunokufuneka njengoko kuchaziwe ngu-2.1093. - I-antenna
Uhlobo lwe-antenna: I-antenna ye-PIFA ene-IPEX isixhumi; Ingeniso ephezulu: 4dBi - Ilebhile kunye nolwazi lokuthotyelwa
Ileyibhile yangaphandle kwimveliso yokugqibela ye-OEM inokusebenzisa amagama anjengala alandelayo:
"Iqulethe i-ID ye-FCC: 2AC7Z-ESPWROOM32UE" kunye
"Iqulethe i-IC: 21098-ESPWROOMUE" - Ulwazi kwiindlela zovavanyo kunye neemfuno zovavanyo ezongezelelweyo
a) Imodyuli yemodyuli ivavanyiwe ngokupheleleyo ngulowo unikwe imodyuli kwinani elifunekayo letshaneli, iintlobo zokumodareyitha, kunye neendlela, akufuneki kube yimfuneko ukuba umfakeli womninimzi aphinde avavanye zonke iindlela zothumelo ezikhoyo okanye useto. Kucetyiswa ukuba umenzi wemveliso engumamkeli, afakele isidluliseli semodyuli, kwaye enze imilinganiselo yophando ukuqinisekisa ukuba inkqubo edityanisiweyo enesiphumo ayigqithi kwimida yokukhutshwayo ebubuxoki okanye imida yomphetho webhendi (umzekelo, apho i-eriyali eyahlukileyo inokubangela ukukhutshwa okongeziweyo) .
b) Uvavanyo kufuneka lujonge izinto ezikhutshwayo ezinokuthi zenzeke ngenxa yokudityaniswa kwezinto ezikhutshwayo kunye nezinye ii-transmitters, i-digital circuitry, okanye ngenxa yeempawu ezibonakalayo zemveliso yomkhosi (indawo evalelweyo). Olu phando lubaluleke kakhulu xa udibanisa iimodyuli ezininzi zothutho apho uqinisekiso lusekwe ekuvavanyeni ngamnye kubo kuqwalaselo oluzimeleyo. Kubalulekile ukuqaphela ukuba abavelisi beemveliso abasindleka akufuneki bacinge ukuba ngenxa yokuba isidluliseli semodyuli siqinisekisiwe ukuba abanalo naluphi na uxanduva lokuthotyelwa kwemveliso yokugqibela.
c)Ukuba uphando lubonisa ukuthotyelwa kwenkxalabo umenzi wemveliso unyanzelekile ukuba awuthobe umba. Iimveliso zokusingatha ezisebenzisa i-modular transmitter zixhomekeke kuyo yonke imigaqo yobugcisa esebenzayo kunye neemeko eziqhelekileyo zokusebenza kumaCandelo 15.5, 15.15, kunye ne-15.29 ukuba angabangela ukuphazamiseka. Umsebenzisi wemveliso yenginginya uya kunyanzeleka ukuba ayeke ukusebenzisa isixhobo de uphazamiseko lulungiswe. - Uvavanyo olongezelelweyo, iSahlulo se-15 seCandelwana B isilanduli Umamkeli wokugqibela/udibaniso lwemodyuli kufuneka luvavanywe ngokuchasene nenkqubo yeFCC yeSigaba 15B yeeradiyetha ezingenziwanga ngabom ukuze zigunyaziswe ngokufanelekileyo ukuba zisebenze njengeSahlulo se-15 sesixhobo sedijithali. Umhlanganisi womkhosi ofaka le modyuli kwimveliso yawo kufuneka aqinisekise ukuba okokugqibela
imveliso ehlanganisiweyo ithobelana neemfuno zeFCC ngovavanyo lobuchule okanye uvandlakanyo lwemithetho yeFCC, kuquka nokusebenza kothumelo, kwaye kufuneka ibhekiselele kwisikhokelo kwi-KDB 996369. Kwiimveliso ezisingisiweyo ezinemodyuli eqinisekisiweyo yokuhambisa imodyuli, uluhlu lwamaxesha ophando lwecomposite. Inkqubo icaciswa ngumgaqo kumaCandelo 15.33(a)(1) ukuya ku (a)(3), okanye uluhlu olusebenzayo kwisixhobo sedijithali, njengoko kubonisiwe kwiCandelo 15.33(b)(1), nokuba loluphi uluhlu lwamaza osasazo aphezulu uphando Xa uvavanya imveliso yokusingatha, zonke ii-transmitter kufuneka zisebenze. Ii-transmitter zinokwenziwa ngokusebenzisa abaqhubi abakhoyo esidlangalaleni kwaye bavulwe, ngoko ke abathumeli bayasebenza. Kwiimeko ezithile, kunokufaneleka ukusebenzisa ibhokisi yokufowuna ethe ngqo kwiteknoloji (iseti yovavanyo) apho i-accessory 50 yezixhobo okanye abaqhubi bangafumanekiyo. Xa kuvavanyelwa izinto ezikhutshwayo kwiradiyetha engenzelwanga ngabom, isidluliseli siya kufakwa kwimowudi yokufumana okanye imo yokungenzi nto, ukuba kunokwenzeka. Ukuba imo yokufumana kuphela ayinakwenzeka ngoko, unomathotholo uya kuba yi-passive (ekhethwayo) kunye/okanye ukuskena okusebenzayo. Kwezi meko, oku kuya kufuneka ukuba kuvuleleke umsebenzi kwi-BUS yonxibelelwano (okt, PCIe, SDIO, USB) ukuqinisekisa ukuba ukujikelezwa kweradiyetha ngempazamo kuvuliwe. Iilabhoratri zovavanyo zinokufuna ukongeza ukuthomalalisa okanye izihluzi ngokuxhomekeke kumandla omqondiso wazo naziphi na iibhikhoni ezisebenzayo (ukuba kufanelekile)
kwirediyo eyenziwe yasebenza. Jonga i-ANSI C63.4, ANSI C63.10, kunye ne-ANSI C63.26 ngeenkcukacha ezingaphezulu zovavanyo ngokubanzi.
Imveliso ephantsi kovavanyo imiselwe kunxulumano lomgca kunye nesixhobo sobambiswano, njengokusetyenziswa kwesiqhelo okucetywayo kwemveliso. Ukunciphisa uvavanyo, imveliso ephantsi kovavanyo isetelwe ukusasaza kumjikelo ophezulu womsebenzi, njengokuthumela file okanye usasaza umxholo othile wemidiya.
