OEM Kev Qhia
- Muaj feem xyuam FCC cov cai
Qhov no module tau tso cai ib leeg Modular pom zoo. Nws ua raws li cov cai ntawm FCC Tshooj 15C, ntu 15.247 cov cai. - Cov kev siv tshwj xeeb ua haujlwm
Cov qauv no tuaj yeem siv rau hauv RF khoom siv. Input voltage mus rau lub module yog nominally 3. 0V-3.6 V DC. Kev ua haujlwm ambient kub ntawm lub module yog -40 txog 85 degrees C. - Cov txheej txheem module txwv
N/A - Trace kav hlau txais xov tsim
N/A - Cov ntsiab lus ntawm RF exposure
Cov cuab yeej ua raws li FCC cov kev txwv tsis pub muaj hluav taws xob tau teeb tsa rau qhov chaw tsis muaj kev tswj hwm. Cov cuab yeej no yuav tsum tau nruab thiab ua haujlwm nrog qhov tsawg kawg nkaus ntawm 20cm ntawm lub tshuab hluav taws xob thiab koj lub cev. Yog tias cov cuab yeej tsim los rau hauv ib lub tswv yim rau kev siv nqa tau yooj yim, qhov kev ntsuam xyuas ntxiv ntawm RF tuaj yeem xav tau raws li tau teev tseg los ntawm 2.1093. - Kav hlau txais xov
Hom kav hlau txais xov: PIFA kav hlau txais xov nrog IPEX connector; Peak nce: 4dBi - Daim ntawv lo thiab cov ntaub ntawv ua raws cai
Daim ntawv lo sab nrauv ntawm OEM cov khoom kawg tuaj yeem siv cov lus xws li hauv qab no:
"Nrog FCC ID: 2AC7Z-ESPWROOM32UE" thiab
"Muaj IC: 21098-ESPWROOMUE" - Cov ntaub ntawv hais txog cov qauv kev xeem thiab cov kev xav tau ntawm kev xeem ntxiv
a) Modular transmitter tau raug kuaj tag nrho los ntawm tus neeg tso cai module ntawm tus naj npawb ntawm cov channel, hom kev hloov pauv, thiab cov qauv, nws yuav tsum tsis txhob tsim nyog rau tus tswv tsev installer kom rov ntsuam xyuas tag nrho cov muaj transmitter hom lossis chaw. Nws raug nquahu kom tus tswv tsev tsim khoom, teeb tsa lub tshuab hloov pauv hloov pauv, thiab ua qee qhov kev soj ntsuam xyuas kom paub meej tias qhov kev sib xyaw ua ke tsis pub dhau qhov txwv tsis pub tshaj tawm los yog band ntug txwv (xws li, qhov sib txawv ntawm tus kav hlau txais xov yuav ua rau muaj kev tawm tsam ntxiv) .
b) Kev ntsuam xyuas yuav tsum kuaj xyuas cov emissions uas yuav tshwm sim vim kev sib xyaw ntawm emissions nrog rau lwm cov transmitters, digital circuitry, los yog vim lub cev muaj zog ntawm cov khoom lag luam (enclosure). Qhov kev tshawb nrhiav no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum sib koom ua ke ntau lub tshuab xa hluav taws xob uas muaj ntawv pov thawj raws li kev sim lawv txhua tus hauv kev teeb tsa ib leeg. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov tuam txhab tsim khoom lag luam yuav tsum tsis txhob xav tias vim tias cov khoom siv hloov pauv tau lees paub tias lawv tsis muaj lub luag haujlwm rau kev ua raws li cov khoom kawg.
c) Yog tias qhov kev tshawb nrhiav pom tias muaj kev cuam tshuam txog kev ua raws li tus tswv tsev cov khoom lag luam yuav tsum tau txo qhov teeb meem. Cov khoom lag luam uas siv lub tshuab xa hluav taws xob hloov pauv tau ua raws li txhua tus neeg siv cov kev cai lij choj raws li txoj cai dav dav ntawm kev ua haujlwm hauv Tshooj 15.5, 15.15, thiab 15.29 kom tsis txhob cuam tshuam. Tus neeg teb xov tooj ntawm cov khoom lag luam yuav tsum tau ua kom tsis txhob ua haujlwm ntawm lub cuab yeej kom txog thaum qhov cuam tshuam tau raug kho. - Kev sim ntxiv, Ntu 15 Subpart B tsis lees paub Qhov kawg tus tswv tsev / cov qauv sib xyaw ua ke yuav tsum tau soj ntsuam tawm tsam FCC Tshooj 15B cov txheej txheem rau lub tshuab hluav taws xob tsis txhob txwm ua kom tau txais kev tso cai zoo rau kev ua haujlwm raws li Tshooj 15 cov khoom siv digital. Tus tswv tsev integrator txhim kho qhov module no rau hauv lawv cov khoom yuav tsum xyuas kom meej tias qhov kawg
Cov khoom sib xyaw ua tau raws li FCC cov cai los ntawm kev ntsuam xyuas lossis kev soj ntsuam ntawm FCC cov cai, suav nrog kev ua haujlwm ntawm lub tshuab xa tawm, thiab yuav tsum xa mus rau cov kev taw qhia hauv KDB 996369. Rau cov khoom lag luam nrog cov ntawv pov thawj modular transmitter, ntau zaus ntawm kev tshawb xyuas ntawm cov khoom sib xyaw. lub kaw lus tau teev tseg los ntawm txoj cai hauv Tshooj 15.33(a)(1) txog (a)(3), lossis ntau yam siv tau rau cov cuab yeej digital, raws li qhia hauv Tshooj 15.33(b)(1), qhov twg yog qhov ntau zaus ntawm kev tshawb nrhiav Thaum kuaj cov khoom lag luam, tag nrho cov transmitters yuav tsum tau ua haujlwm. Cov transmitters tuaj yeem siv tau los ntawm kev siv cov tsav tsheb uas muaj rau pej xeem thiab qhib, yog li cov transmitters tau ua haujlwm. Hauv qee qhov xwm txheej, nws yuav tsim nyog siv lub thawv hu xov tooj tshwj xeeb (test set) qhov twg cov khoom siv 50 lossis cov tsav tsheb tsis muaj. Thaum kuaj cov emissions los ntawm lub unintentional radiator, lub transmitter yuav tsum tau muab tso rau hauv lub receiver hom los yog idle mode, yog hais tias ua tau. Yog tias tau txais hom nkaus xwb tsis tuaj yeem ua tau, lub xov tooj cua yuav tsum yog passive (nyiam dua) thiab / lossis active scanning. Hauv cov xwm txheej no, qhov no yuav tsum tau ua kom muaj kev ua haujlwm ntawm kev sib txuas lus BUS (piv txwv li, PCIe, SDIO, USB) kom ntseeg tau tias lub tshuab hluav taws xob tsis muaj zog tau qhib. Cov chaw soj ntsuam kuaj yuav xav tau ntxiv qhov txo qis lossis cov lim dej nyob ntawm lub teeb liab lub zog ntawm cov beacons nquag (yog tias tsim nyog)
los ntawm xov tooj cua enabled. Saib ANSI C63.4, ANSI C63.10, thiab ANSI C63.26 kom paub meej ntxiv txog kev xeem.
Cov khoom nyob rau hauv kev sim yog teem rau hauv ib txoj kab kev koom tes nrog ib tug sib koom tes ntaus ntawv, raws li ib txwm npaj siv ntawm cov khoom. Txhawm rau kom yooj yim rau kev sim, cov khoom nyob rau hauv kev sim tau teeb tsa kom xa mus rau lub voj voog ua haujlwm siab, xws li xa mus rau file los yog streaming ib co xov xwm cov ntsiab lus.
FCC nqe lus
