Quality effects of wireless VoIP using security solutions

The challenge for wireless voice-over-IP (VoIP) is to achieve both voice quality and efficient use of spectrum. VoIP over wireless network (VoWLAN) has higher security vulnerabilities. Secured wireless VoIP presents many challenges to providing quality voice communication. This paper presents the results of an experimental analysis of the transmission of voice over a secure communication wireless network implementing various security solutions. The experimental results demonstrate how choices in voice-packet security and IP security influence the overall design decisions. This study raised an awareness of the effects of the various security solutions on voice qualities that must be considered when deploying VoIP in the wireless networks.
