VoWiFi considerations for delay and jitter

  • Refer to vendor of the VoWiFi devices documentation for the minimum requirements for delay, jitter.
  • Typically time-sensitive applications such as VoIP require that higher-layer IP packet loss be no greater than 2 percent.
  • VoWiFi networks need to limit layer 2 retransmissions to 5 percent or less to guarantee the timely and consistent delivery of VoIP packets.
  • When layer 2 retransmissions exceed 5 percent, latency problems may develop and jitter problems will most likely surface.
