WebAug 16, 2024 · AMR was released in 1999; patents will presumably be expiring by 2024. AMR-WB and -WB+ are 3-5 years newer. Obviously there could be complications with the patent situation, and given that VoiceAge claims there are 150 essential patents in its AMR* portfolio, it would take real legal work to try to dig up a full list. WebIt also interoperates with VMR-WB, the latest 3GPP2 wideband speech standard, which is mandatory for cdma2000 ® wideband telephony and multimedia messaging services. G.722.2/AMR-WB supports dynamic adaptation to network conditions, using lower bit rates during network congestion or degradation while preserving audio quality. WebTelian 2G-verkossa AMR-WB koodekille käytetään matalampia bittinopeuksia kuin Telian 3G-verkossa. Täten äänenlaatu 2G-verkossa on huonompi kuin 3G-verkossa, vaikka käytettäisiin AMR-WB:tä. Vielä huonommaksi tilanne menee, jos ruuhkan takia pudotetaan AMR-WB pois ja siirrytään HR ja AMR 5,15 koodekkeihin. hub centric ring 73mm/60mm
