Published by: Mind Commerce Publishing
Published: September 2004
Product Code: R331-0014Description Introduction
The convergence of two highly disruptive technologies, VoIP and WLAN, is set to drastically alter the way we communicate, do business, and play. VoWLAN represents both an opportunity and a threat to traditional business and communications. This report provides the foundation knowledge and understanding necessary to capitalize on this evolution from wireline to wireless and from circuit to packet.
Purpose of VoWLAN Fundamentals
Where other reports fall short, providing only forecast data for the VoWLAN market, VoWLAN Fundamentals is intended to help the reader learn the fundamentals of how to design, integrate and maintain a VoWLAN system. In addition to providing an excellent foundation knowledge to the technical and business issues involved in the convergence of VoIP and WLAN, this report provides enough information to assist in planning the business case and technical challenges of a VoWLAN deployment.
Target Audience for the Report
While this report will be of interest to anyone involved in the business, engineering, planning, and/or operation of a VoWLAN network or service offering, VoWLAN Fundamentals will be of particular value to the following groups:
