Investigating the Performance of VOIP over WLAN in Campus Network

Abstract

Voice will remain a fundamental communication media that cuts across people of all walks of life. VoIP, a new technology has been increasingly popular in recent times due to its affordability and reduced cost in making calls over broadband Internet. This paper uses simulation method to specifically investigate the performance of VoIP over wireless LAN for an increased number of VoIP calls, the use of different coding scheme and increased number of workstations in video conferencing. With this, a determination of the actual number of VoIP calls that each wireless Access point can adequately support with enhanced voice quality was made alongside with the coding scheme that yields the best quality of service in wireless LAN.
