Iimfuno zesatifikethi ze-FCC HAC zokulawula umthamo

I-FCC ifuna ukuba ukususela nge-5 kaDisemba 2023, i-terminal ebanjwe ngesandla kufuneka ihlangabezane nomgangatho we-ANSI C63.19-2019 (HAC 2019).
Umgangatho wongeza iimfuno zovavanyo loMqulu, kwaye i-FCC inike i-ATIS 'isicelo sokukhululwa ngokuyinxenye kuvavanyo lokulawula umthamo ukuvumela i-terminal ebanjwe ngesandla ukuba iphumelele isiqinisekiso se-HAC ngokukhupha inxalenye yovavanyo lokulawula umthamo.

Iimfuno zovavanyo lobuchwephesha lokuguqula inzuzo yencoko yababini, ukugqwetha, kunye novavanyo lokuphendula rhoqo kwe-KDB 285076 D04 yolawulo lwevolumu phantsi kwemeko yokuxolelwa DA 23-914

1.Ngokwe-exemption, kuphela i-CMRS Narrowband kunye ne-CMRS Wideband voice encoders ezifunekayo ukuhlangabezana neemfuno zokulawula umthamo womgangatho we-TIA 5050-2018 woLawulo loMqulu:
1) Uvavanyo lokusebenzisa amandla e-2N
Kuvavanyo olusebenzisa imikhosi ye-2N, iinkonzo zelizwi kunye neebhendi zokusebenza kuzo zonke izixhobo ezibambe ngesandla kunye nesethingi yolawulo lwevolumu yebhanti enye encinci kunye ne-wideband voice codec kwi-interface yomoya usebenzisa i-encoder ratio ekhethwe ngumfaki-sicelo kufuneka ibe neseshoni enye inzuzo≥ 6dB.
2) Uvavanyo lokusebenzisa amandla e-8N
Uvavanyo olusebenzisa imikhosi ye-8N, iinkonzo zelizwi kunye neebhendi zokusebenza kuzo zonke izixhobo ezibambe ngesandla kunye noseto lolawulo lwevolyum yebhanti enye encinci kunye ne-wideband voice codec kwi-interface yomoya usebenzisa i-encoder ratio ekhethwe ngumfaki-sicelo kufuneka ibe neseshoni enye inzuzo≥ I-6dB.
2. Kwezinye ii-codecs zomsindo ezingavavanywanga kwi-2), ukuphazamiseka kokumkela, ukusebenza kwengxolo, kunye nefrikhwensi yokwamkelwa komsindo kwi-TIA 5050-2018 nayo ayidingeki, kodwa ezi codecs zomsindo kufuneka zivavanye inzuzo yeseshoni enkulu kune-6dB kwi-2N kwaye I-8N ithi kuzo zonke iinkonzo zelizwi, iibhendi zokusebenza kunye nojongano lomoya lwe-terminal engenazingcingo.

 

Ezinye iimfuno zesatifikethi
1.Ileyibhile yokupakisha iya kuhambelana neemfuno ze-47 CFR Icandelo le-20.19 (f) (1) kwaye ibonise eyona nzuzo yeseshoni efunyenwe phantsi kweemeko zokukhululwa kwe-codec eyamkelwe kwi-1) kunye ne-2) ngasentla kunye ne-2N kunye ne-8N yamandla asetyenzisiweyo.
2.Ukongezelela kwiimfuno ezichazwe kwi-1) kunye ne-2) ngasentla, zonke iinkonzo zezwi, i-codec, iibhendi zokusebenza, kunye ne-interfaces zomoya ezifanelekile ukukhululwa kwe-HAC kufuneka zihambelane ne-2019 ANSI Standard Section 4 WD RF Interference, iCandelo 6 WD T- Uvavanyo lwesiginali yekhoyili.
3.Emva kwe-5 kaDisemba 2023, iitheminali eziphathwa ngesandla kufuneka ziqinisekiswe ngeemeko zokuxolelwa okanye zihlangabezane ngokupheleleyo nomgangatho we-ANSI we-2019 kunye ne-TIA 5050 yomgangatho wokulawula uMqulu. Emva kokuba ixesha lokuyeka liphelile, ukuba akukho manyathelo athatyathwa yiKhomishoni, iitheminali eziphathwayo ziya kuqwalaselwa ngokuhambelana neemfuno zokuva uncedo lokuva ukuba zihlangabezana nomgangatho opheleleyo we-ANSI we-2019 kunye nomgangatho wokulawula umthamo we-TIA 5050.
4.Iimeko zokuxolelwa ziphela kwiminyaka emibini emva komhla wokukhutshwa koMyalelo we-Exemption DA 23-914, kwaye iitheminali eziphathwa ngesandla ezifunyenwe phantsi kwalo mqathango ziya kukhululwa njengoncedo lokuva oluhambelanayo.
5.Ukuze uqinisekise ukuthotyelwa kwayo kwingxelo yovavanyo, i-terminal ephathwayo inokubhekisa kwindlela yovavanyo eyenziwe lula ehambelanayo ngokwamava ukunciphisa inani lovavanyo.
Kuba ayizizo zonke ii-codecs ezixhaswa sisixhobo ekufuneka zifezekise iimfuno, akukhathaliseki nokuba ezi codecs ziyahlangabezana neemfuno okanye nokuba inzuzo yeseshoni kufuneka ivavanywe ngokuchasene nokuxolelwa, ingxelo yovavanyo kufuneka iqulathe uluhlu lwazo zonke iikhowudi ezixhaswa sisixhobo. .
