VoWLAN Applications and Benefits

Chapter Description

This chapter describes various applications of Voice over Wireless LAN (VoWLAN) systems. Real-world examples and case studies provide you with a solid understanding of how VoWLAN can benefit a company. Details are also given about tangible benefits and expected return on investment (ROI).


A university environment is highly mobile, with teaching staff and students moving among different classrooms, libraries, and offices. The use of VoWLANs at a university offers tremendous benefits by enabling university staff to stay in touch from anywhere on campus. This capability makes teachers more accessible to students, and the learning environment is much safer. A teacher, for example, can report safety issues as they occur, rather than having to wait until a class ends.

A challenge of deploying a VoWLAN system at a university is that coverage must include a wide variety of buildings and outdoor areas. An extensive RF site survey is very important to take into account the varying facility construction and obstacles blocking radio waves. Even after installing the system, reevaluating coverage from time to time is generally necessary to determine whether student traffic and campus functions offer major signal attenuation.
