Hordhac FCC HAC 2019 Shuruudaha Imtixaanka Xakamaynta Mugga iyo Heerarka gudaha Mareykanka

Guddiga Isgaarsiinta Federaalka (FCC) ee dalka Mareykanka wuxuu u baahan yahay in laga bilaabo Diseembar 5, 2023, dhammaan aaladaha gacanta lagu qaato waa in ay buuxiyaan shuruudaha ANSI C63.19-2019 (ie heerka HAC 2019). Marka la barbar dhigo nooca hore ee ANSI C63.19-2011 (HAC 2011), farqiga ugu weyn ee u dhexeeya labada been waa ku darida shuruudaha tijaabada mugga ee heerka HAC 2019. Walxaha tijaabinta inta badan waxaa ku jira qallooc, jawaab celin joogto ah, iyo faa'iidada fadhiga. Shuruudaha khuseeya iyo hababka imtixaanku waxay u baahan yihiin inay tixraacaan heerka ANSI/TIA-5050-2018.
US FCC waxay soo saartay 285076 D05 HAC Waiver DA 23-914 v01 qaanuunka dhaafitaanka Sebtembar 29, 2023, oo leh muddo 2 sano ah oo ka bilaabmaysa Diisambar 5, 2023. Waxa loo baahan yahay in codsiyada shahaadaynta cusub waa inay u hoggaansamaan shuruudaha 285076 D04 Xakamaynta Mugga v02 ama iyada oo la socota dukumeentiga nidaamka ka-dhaafitaanka ku-meel-gaadhka ah ee KDB285076 D05 HAC Waiver DA 23-914 v01 ee hoos yimaada 285076 D04 Xakamaynta Mugga v02. Ka-dhaafitaankani wuxuu u oggolaanayaa aaladaha gacanta lagu qaato ee ka qaybqaata shahaado inay hoos u dhigaan shuruudaha imtixaannada qaarkood iyadoo la raacayo hababka tijaabada ANSI/TIA-5050-2018 si ay ugu gudbaan imtixaanka Xakamaynta Mugga.
Imtixaanka Xakamaynta Mugga, shuruudaha ka-dhaafitaanka gaarka ah waa sida soo socota:
(1) Si loo tijaabiyo koodka cidhiidhiga ah iyo koodka balaadhka ah ee adeegyada teleefoonada shabakada wirelesska (sida AMR NB, AMR WB, EVS NB, EVS WB, VoWiFi, iwm.), shuruudaha waa sida soo socota:
1) Cadaadiska 2N ee hoos yimaada, codsaduhu wuxuu dooranayaa cod-koobeedka cidhiidhiga ah iyo heerka codaynta ballaadhan. Mug cayiman, dhammaan adeegyada codka, hawlgallada bandowga, iyo dejinta dekedda hawada, faa'iidada fadhigu waa inay noqotaa ≥ 6dB, iyo falcelinta qallooca iyo soo noqnoqda waa inay buuxisaa shuruudaha caadiga ah.
2) Marka la eego cadaadiska 8N, codsaduhu wuxuu dooranayaa heerka codaynta cidhiidhiga ah iyo heerka codaynta broadband, iyo dhammaan adeegyada codka, hawlgallada band, iyo dejinta dekedaha isla mugga, faa'iidada fadhiga waa inay noqotaa ≥ 6dB, halkii ay ka ahaan lahayd heerka ≥ 18dB Qallooca iyo jawaab celinta soo noqnoqda ayaa buuxinaysa shuruudaha heerka.
(2) Codsiyada kale ee cidhiidhiga ah iyo kuwa ballaadhan ee aan lagu xusin shayga (1), faa'iidada fadhigu waa inay noqotaa ≥ 6dB xaaladaha cadaadiska 2N iyo 8N, laakiin looma baahna in la tijaabiyo qallooca iyo jawaab celinta soo noqnoqda.
(3) Hababka kale ee codaynta ee aan lagu sheegin sheyga (1) (sida SWB, FB, OTT, iwm.), uma baahna inay buuxiyaan shuruudaha ANSI/TIA-5050-2018.
Ka dib Diisambar 5, 2025, haddii FCC aysan soo saarin dukumeenti dheeri ah, Tijaabada Xakamaynta Mugga ayaa si adag loo fulin doonaa si waafaqsan shuruudaha ANSI/TIA-5050-2018.
Shaybaarka Tijaabada BTF wuxuu leeyahay awooda tijaabada shahaado ee HAC 2019, oo ay kujirto faragelinta RF Emission RF, Tijaabada calaamada T-Coil, iyo Shuruudaha xakamaynta mugga xakamaynta.
