Thaum kuaj cov emissions los ntawm lub radiator tsis txhob txwm, 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 kev siv tshuaj ntsuam xyuas. 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 cov xov tooj cua qhib. 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 qho kev sib txuas / kev koom tes nrog cov cuab yeej sib koom ua ke, raws li ib txwm xav siv ntawm cov khoom. Txhawm rau kom yooj yim rau kev sim, cov khoom nyob rau hauv kev sim yog teem rau kis ntawm lub voj voog ua haujlwm siab, xws li xa mus rau file los yog streaming ib co xov xwm cov ntsiab lus.

FCC ceeb toom:
Ib qho kev hloov pauv lossis kev hloov kho uas tsis tau pom zoo los ntawm pawg neeg saib xyuas kev ua raws cai tuaj yeem ua rau tus neeg siv txoj cai los khiav cov khoom siv. Cov cuab yeej no ua raws li Tshooj 15 ntawm FCC Cov Cai. Kev ua haujlwm yog ua raws li ob qho xwm txheej hauv qab no: (1) Cov cuab yeej no yuav tsis ua rau muaj kev cuam tshuam tsis zoo, thiab (2) Cov cuab yeej no yuav tsum lees txais kev cuam tshuam tau txais, suav nrog kev cuam tshuam uas yuav ua rau kev ua haujlwm tsis zoo.
