VoIP is an essential for the delivery of voice communication and sees wide applications in office and home use. VoIP over Wifi although not as high in quality as VoIP over Ethernet is connectionless and is popularized by mobile phone applications such as NetTalk and Viber. We will be examining how delay, jitter, packet loss contribute to congestion and affect the voice quality.
