Question
The following parameters are known in a wireless network VoIP codec: the voice packetisation interval is 10 ms, the raw voice bit rate is 32
The following parameters are known in a wireless network VoIP codec: the voice packetisation interval is 10 ms, the raw voice bit rate is 32 Kbps, 4 voice payload frames are encapsulated per IPv4 packet, and the standard RTP/UDP/IPv4 protocol suite is used to transmit the VoIP packets.
1. Calculate the voice payload size after packetization.
2. Calculate the minimal required bandwidth at the IP level (without considering padding) to transmit the VoIP packets in one direction (assuming basic headers without option fields and no header compression or silence suppression used).
