FCC HAC certification zvinodiwa zvekudzora vhoriyamu

Iyo FCC inoda kuti kubva muna Zvita 5, 2023, inobatwa nemaoko terminal inofanirwa kusangana ne ANSI C63.19-2019 standard (HAC 2019).
Iyo chiyero inowedzera Volume control yekuyedza zvinodiwa, uye FCC yakapa ATIS 'chikumbiro chekuregererwa kubva pavhoriyamu yekudzora bvunzo kubvumidza inobatwa nemaoko terminal kupasa HAC chitupa nekusiya chikamu chevhoriyamu yekudzora bvunzo.

Tekinoroji bvunzo zvinodiwa pakugadzirisa iyo nhaurirano kuwana, kukanganisa, uye frequency mhinduro bvunzo dzeKDB 285076 D04 vhoriyamu kutonga pasi pekusabvumirwa mamiriro DA 23-914.

1. Maererano nekuregererwa, chete CMRS Narrowband neCMRS Wideband encoders yezwi ndiyo inodiwa kuti isangane nekudzora vhoriyamu zvinodiwa zveTIA 5050-2018 Volume Control standard:
1) Muedzo wekushandisa 2N simba
Kune bvunzo dzinoshandisa mauto e2N, masevhisi ezwi uye mabhendi anoshanda ezvishandiso zvese zvakadzikwa nemaoko uye vhoriyamu yekudzora marongero eimwe narrowband uye imwe wideband voice codec mumhepo interface uchishandisa encoder reshiyo inosarudzwa nemunyoreri inofanirwa kuwana kanenge chikamu chimwe chete ≥ 6dB.
2) Muedzo wekushandisa 8N simba
Kune bvunzo dzinoshandisa mauto e8N, masevhisi ezwi uye mabhendi anoshanda ezvishandiso zvese zvakakamisikidzwa nemaoko uye vhoriyamu yekudzora marongero eimwe narrowband uye imwe wideband voice codec mumhepo interface uchishandisa encoder reshiyo inosarudzwa nemunyoreri inofanirwa kuwana kanenge chikamu chimwe chete ≥ 6dB.. Hapana chikonzero chekusangana kana kudarika zvizere 18dB chikamu chekuwana zvinodiwa zvinotsanangurwa muTIA 5050 Chikamu 5.1.1.
2. Kune mamwe maodhiyo macodec asina kuongororwa mu2), kukanganisa kwekugamuchira, kuita ruzha, uye odhiyo yekugamuchira frequency muTIA 5050-2018 haidiwewo, asi aya macodec ekuteerera anofanirwa kuongorora chikamu chechikamu chikuru kupfuura 6dB pa2N uye. 8N inotaura nezvese masevhisi ezwi, mabhendi anoshanda uye nzvimbo dzemhepo dzeiyo isina waya terminal.

 

Zvimwe zvinodiwa certification
1.Chiratidzo chekuputira chichaenderana nezvinodiwa zve 47 CFR Chikamu 20.19 (f) (1) uye chinoratidza chiitiko chaicho chinowanikwa pasi pemitemo yekuregererwa kwekodec yakagamuchirwa mu1) uye 2) pamusoro uye 2N uye 8N inoshandiswa simba inotaura.
2.Kuwedzera kune zvinodiwa zvakataurwa mu1) uye 2) pamusoro, ese masevhisi ezwi, koDEC, mabhendi anoshanda, uye nzvimbo dzemhepo dzinokodzera kusunungurwa kweHAC dzinofanirwa kuenderana ne2019 ANSI Standard Section 4 WD RF Interference, Chikamu 6 WD T- Coil chiratidzo chekuyedza.
3.Pashure paZvita 5, 2023, materminals anobatwa nemaoko anofanirwa kusimbiswa nemamiriro ekuregererwa kana kusangana zvizere ne2019 ANSI standard uye TIA 5050 Volume control standard. Mushure mekunge nguva yekuregera yapera, kana pasina chimwe chiito chinotorwa neKomisheni, zviteshi zvakabatwa nemaoko zvichaonekwa sezvinodiwa zvinoenderana nerubatsiro rwekunzwa kana dzikazadzisa yakazara 2019 ANSI standard uye yakabatana TIA 5050 vhoriyamu yekudzora chiyero.
4.Mamiriro ekuregererwa anopera makore maviri mushure mezuva rekubudiswa kweExemption Order DA 23-914, uye zvigaro zvemaoko zvakawanikwa pasi pemamiriro ezvinhu aya zvichange zvisingabvumirwi sekubatsira kwekunzwa kunoenderana.
5.Kuitira kuratidza kutevedzera kwayo mumushumo webvunzo, iyo inobatwa ruoko inogona kureva inoenderana yakapfava nzira yekuyedza zvinoenderana neruzivo kudzikisa huwandu hwekuyedzwa.
Sezvo asiri ese macodecs anotsigirwa nemudziyo anofanirwa kuzadzisa zvinodiwa, hazvina basa kuti aya macodecs anozadzisa zvinodiwa here kana kuti chikamu chechikamu chinoda kuongororwa chinopesana nekuregererwa, mushumo webvunzo unofanirwa kunge uine runyorwa rweese macodecs anotsigirwa nemudziyo. .
