Voice over Wireless LANs (VoWi-Fi) ^TM

An advanced class that prepares you for the next big thing in WiFi networking and wireless handset design

Course Description:
Enterprises, residences, and public sites commonly feature Wi-Fi Wireless LANs. Most users employ these networks for their data applications. At the same time, most data networks are carrying Voice over IP. When most Wi-Fi networks carry Voice over IP with sufficient quality, mobile subscribers will find those networks a cost-effective supplement to cellular services.

This Course provides both the market and technology perspectives on the transport of voice over Wireless LANs.

Course length:
2 days

Audience:
This course is designed for students who are working on Wi-Fi products and services, or Voice over IP projects. In private settings, DoceoTech includes a brief introduction to Wi-Fi for groups of students who know about VoIP, or a brief intro to VoIP for students who already know their Wi-Fi; or both, if desired. After that foundation is set in both technologies, we teach the detailed strategic, technical, and implementation issues that are unique to a VoWi-Fi service.
 

This DoceoTech course was authored by Michael Stanford. Mr. Stanford presented the keynote address at the Voice on the Net conference in March 2005, on the topic “Voice over Wi-Fi: Current State of Play.” He is a VoIP strategist who has worked in executive positions in three companies that provide converged voice/data solutions, and he continues to drive the VoIP industry to new innovative solutions
