Monitoring and Troubleshooting VoIP Networks with a Network Analyzer

VoWLAN-Specific Factors

Wireless networking introduces specific problems affecting the quality of VoIP conversations. There are a limited number of users who can use a single wireless access point at the same time while maintaining acceptable voice quality. Limited reception and low signal strength alter available bandwidth and affect the number of retries. Adjusting the settings of endpoints and wireless access points to permit prioritizing voice traffic over data with the use of Quality of Service (QoS) allows for increased call quality with no extra effort.

VoIP over wireless networks may suffer from numerous problems that are nonexistent on wired networks. This chapter discusses the various factors that affect the quality of VoIP calls transferred over wireless networks.
