PDF of this tutorial

This tutorial has shown that the technology exists today to implement VoIP over WLANs applications as an integral part of next-generation seamless wireless voice/data networks. The wireless industry has already begun to migrate toward an environment where one phone number can be used practically anywhere for voice and data applications. To accomplish this goal, mobile device designers, carriers, service providers and enterprise/home network designers face deployment, provisioning and implementation issues, many of which were described in this tutorial.

In summary, some of this tutorial's major conclusions are as follows:

• The data rates of current 802.11a/g MAC/baseband processors will support the throughput needs of VoIP over WLAN applications as well as other next-generation multimedia applications like video streaming.
• RF interference will be a factor in deploying next-generation wireless networks that include 802.11 WLAN capabilities.
• 802.11 AP-to-AP handoffs in VoIP over WLAN applications can be managed effectively with today's technology.
