Module iyi imapatsidwa Chivomerezo cha Modular Imodzi. Imagwirizana ndi zofunikira za FCC gawo 15C, malamulo a gawo 15.247. - Makhalidwe ogwiritsira ntchito
Gawoli litha kugwiritsidwa ntchito pazida za RF. Kulowetsa voltage ku gawoli ndi 3. 0V-3.6 V DC. Kutentha kozungulira kwa gawoli ndi -40 mpaka 85 ° C. - Njira zochepa za module
N / A - Tsatirani kapangidwe ka mlongoti
N / A - Malingaliro okhudzana ndi RF
Zipangizozi zimagwirizana ndi malire a FCC okhudzana ndi ma radiation omwe akhazikitsidwa kumalo osalamulirika. Zidazi ziyenera kuyikidwa ndikugwiritsidwa ntchito ndi mtunda wochepera 20cm pakati pa radiator ndi thupi lanu. Ngati zidazo zidapangidwa kuti zizigwiritsidwa ntchito kunyamula, kuwunika kowonjezera kwa RF kungafunike monga momwe 2.1093 yafotokozera. - Mlongoti
Mtundu wa mlongoti: PIFA mlongoti wokhala ndi IPEX cholumikizira; Kupindula kwakukulu: 4dBi - Zolemba ndi zotsatila
Cholembera chakunja pamapeto a OEM chingagwiritse ntchito mawu monga awa:
"Muli FCC ID: 2AC7Z-ESPWROOM32UE" ndi
"Muli IC: 21098-ESPWROOMUE" - Zambiri zamitundu yoyesera ndi zofunikira zina zoyesera
a) Ma modular transmitter ayesedwa mokwanira ndi wopereka ma module pa nambala yofunikira ya ma tchanelo, mitundu yosinthira, ndi mitundu, sikuyenera kukhala kofunikira kuti wokhazikitsayo ayeserenso mitundu kapena zosintha zonse zomwe zilipo. Ndikoyenera kuti wopanga zinthu, ayike modulira modular, ndikuchita miyeso yofufuzira kuti atsimikizire kuti makina ophatikizika omwe abwerawo sadutsa malire operekera zinthu zabodza kapena malire am'mphepete mwa bandi (mwachitsanzo, pomwe mlongoti wina ukupangitsa kuti pakhale mpweya wowonjezera) .
b) Kuyesaku kuyenera kuyang'ana mpweya womwe ungachitike chifukwa cha kusakanikirana kwa mpweya ndi ma transmitters ena, ma dijiti ozungulira, kapena chifukwa cha mawonekedwe a chinthucho (mpanda). Kufufuza kumeneku ndikofunikira kwambiri pakuphatikiza ma transmitters angapo amtundu wa modular pomwe chiphasocho chimachokera pakuyesa aliyense wa iwo poyimirira yekha. Ndikofunika kuzindikira kuti opanga zinthu zochititsa chidwi sayenera kuganiza kuti chifukwa chotumizira modular ndi chovomerezeka kuti alibe udindo wotsatira zomaliza.
c) Ngati kafukufuku akuwonetsa kutsatiridwa ndi zomwe wopanga akuyenera kuti achepetse vutolo. Zogulitsa zomwe zimagwiritsa ntchito modular transmitter zimatsatiridwa ndi malamulo onse aukadaulo komanso momwe amagwirira ntchito mu Ndime 15.5, 15.15, ndi 15.29 kuti asasokoneze. Wogwiritsa ntchito chipangizocho adzakakamizika kusiya kugwiritsa ntchito chipangizocho mpaka vutolo litakonzedwa. - Kuyesa kowonjezera, Gawo 15 Gawo B Lodziletsa Kuphatikizika komaliza kwa wolandira/magawo kuyenera kuwunikidwa molingana ndi mfundo za FCC Gawo 15B za ma radiator osafuna kuti aloledwe kugwira ntchito ngati chipangizo cha digito cha Gawo 15. Wophatikiza wolandila akukhazikitsa gawoli muzinthu zawo ayenera kuonetsetsa kuti komaliza
zopangidwa zophatikizika zimagwirizana ndi zofunikira za FCC powunika mwaukadaulo kapena kuwunika kwa malamulo a FCC, kuphatikiza magwiridwe antchito a transmitter, ndipo ziyenera kuloza ku chitsogozo cha KDB 996369. dongosolo latchulidwa ndi lamulo la mu Ndime 15.33(a) (1) mpaka (a) (3), kapena mitundu yomwe ikugwiritsidwa ntchito pa chipangizo cha digito, monga momwe zasonyezedwera mu Gawo 15.33(b)(1), malingana ndi kuchuluka kwa mafupipafupi a kufufuza Poyesa mankhwala omwe ali nawo, ma transmitter onse ayenera kukhala akugwira ntchito. Ma transmitter amatha kuthandizidwa pogwiritsa ntchito madalaivala omwe amapezeka pagulu ndikuyatsidwa, kotero ma transmitter akugwira ntchito. Nthawi zina, kungakhale koyenera kugwiritsa ntchito bokosi loyimba laukadaulo laukadaulo (seti yoyesera) pomwe zida 50 kapena madalaivala palibe. Poyesa zotulutsa kuchokera ku radiator mosakonzekera, chotumiziracho chimayikidwa munjira yolandirira kapena mopanda ntchito, ngati kuli kotheka. Ngati kulandila kokha sikungatheke, wailesiyi ikhala yokhazikika (yokondedwa) ndi/kapena kusanthula mwachangu. Pazifukwa izi, izi zingafunike kuti zitheke kugwira ntchito pa BUS yolumikizirana (ie, PCIe, SDIO, USB) kuwonetsetsa kuti ma radiator osakonzekera akuyatsidwa. Malo oyesera angafunikire kuwonjezera zochepetsera kapena zosefera kutengera mphamvu ya siginecha ya mabekoni aliwonse omwe akugwira ntchito (ngati kuli kotheka)
kuchokera pawayilesi woyatsidwa. Onani ANSI C63.4, ANSI C63.10, ndi ANSI C63.26 kuti mumve zambiri za kuyezetsa.
Chogulitsa chomwe chikuyesedwa chimayikidwa mumzere wolumikizana ndi chipangizo cholumikizirana, malinga ndi momwe amagwiritsidwira ntchito nthawi zonse. Kuti muchepetse kuyezetsa, chinthu chomwe chikuyesedwa chimayikidwa kuti chifalikire pamlingo wapamwamba kwambiri, monga kutumiza file kapena kusakatula zina zapa media.
Chidziwitso cha FCC
Chipangizochi chikugwirizana ndi Gawo 15 la Malamulo a FCC. Kugwira ntchito kumadalira zinthu ziwiri izi:
(1) chipangizochi sichingayambitse mavuto, ndipo (2) chipangizochi chikuyenera kuvomereza zosokoneza zilizonse
(2) adalandira, kuphatikizapo kusokoneza komwe kungayambitse ntchito yosafunika.
Chenjezo la FCC:
Kusintha kulikonse kapena kusintha komwe sikunavomerezedwe mwachindunji ndi gulu lomwe limayang'anira kutsata kungathe kulepheretsa wogwiritsa ntchito kugwiritsa ntchito zidazo.
“Zipangizozi zayesedwa ndipo zapezeka kuti zikugwirizana ndi malire a chipangizo cha digito cha Gulu B,
motsatira gawo 15 la Malamulo a FCC. Malire awa adapangidwa kuti aziteteza moyenera ku kusokonezedwa kowopsa pakuyika nyumba. Chipangizochi chimapanga, chimagwiritsa ntchito, komanso chimatha kuyatsa mphamvu zamawayilesi ndipo, ngati sichinayikidwe ndi kugwiritsidwa ntchito motsatira malangizo, chikhoza kusokoneza njira zoyankhulirana ndi wailesi. Komabe, palibe chitsimikizo kuti kusokoneza sikudzachitika mu unsembe winawake. Ngati chida ichi chikuyambitsa kusokoneza koyipa kwa wailesi kapena kulandila wailesi yakanema, komwe kungadziwike ndikuzimitsa ndi kuyatsa zida, wogwiritsa ntchitoyo akulimbikitsidwa kuyesa kusokoneza ndi chimodzi kapena zingapo mwa izi:
- Yankhanitsaninso kapena sinthani mlongoti wolandira.
- Wonjezerani kulekana pakati pa zida ndi wolandila.
- Lumikizani chipangizocho munjira yosiyana ndi yomwe wolandila amalumikizidwa.
- Funsani wogulitsa kapena wodziwa ntchito pa wailesi/TV kuti akuthandizeni.”
Chidziwitso cha IC:
Chipangizochi chimagwirizana ndi mulingo wa RSS wopanda licence wa Industry Canada. Kugwira ntchito kumadalira zinthu ziwiri izi: (1) chipangizochi sichingasokoneze,
ndipo (2) chipangizochi chiyenera kuvomereza kusokoneza kulikonse, kuphatikizapo kusokoneza komwe kungayambitse ntchito yosayenera ya chipangizocho.
