Abstract

The adoption of Voice over Wireless Local Area Network is on tremendous increase due to its ease, non-intrusive and inexpensive deployment, low maintenance cost, universal coverage and basic roaming capabilities. However, deploying Voice over Internet Protocol (VoIP) over Wireless Local Area Network (WLAN) is a challenging task for many network managers, architects, planners, designers and engineers, hence the need for a guideline to design, model and simulate the network before deployment. This work analyzed parameters such as latency, jitter, packet loss, codec, bandwidth, throughput, voice data length and de-jitter buffer size, which quantify the quality of degradation over the network. The analytical mathematical E-model was used to predict the readiness of the existing network to support VoIP. The Transmission Rating Factor R was calculated as 85.08 indicating a high speech quality and excellent user satisfaction. Riverbed Modeller Academic Edition was used to model and simulate the network. Results from this project work show that VoIP can be successfully deployed on WLAN with perceived high speech quality, user’s satisfaction, low delay and high throughput.
