FAQ's

What is the VoLTE payload for AMR-WB 23.85 kbps codec?

VoLTE generates packets after every 20 ms so in 1000 ms, there would be 50 packets (1000/20 = 50). For a VoLTE codec of AMR-WB 23.85 kbps the codec generates 23.85 kilobits per second and it generates 50 packets per second. Hence each AMR-WB 23.85 packet contains 477 bits (23850/50 = 477). This is the size of the VoLTE payload for a VoLTE codec of AMR-WB 23.85 kbps

How much is the VoLTE overhead for AMR-WB 23.85 kbps codec?

It is expected to have some overhead due to IP type of traffic (PS domain). There will be overheads like headers (IP, UDP, RTP) that needs to be added to each packet for VoLTE dimensioning. A typical IPv4 header is around 20 Bytes and as an overall estimation considering also the other protocol layer of UDP & RTP, the overhead will be around 40 bytes (320 bits) to 45 bytes (360 bits) of overhead.

How much backhaul capacity is needed for an IPv4 VoLTE call on AMR-WB 23.85 kbps codec?

Considering a Volte call with AMR-WB 23.85 kbps codec rate, the total bits per VoLTE packet will be around 477 + 360 = 837 bits since 477 is the VoLTE payload and 360 is the VoLTE overhead for IPv4 plus the UDP & RTP headers. So, in one second having 1000/20 = 50 VoLTE packets, we shall have 41.85 kilobits (837 bits per packet * 50 packets per second). This means that a typical VoLTE data rate for AMR-WB 23.85 codec will be around 42 kbps.
