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).


Enterprises are taking advantage of VoWLAN applications to provide mobility to workers and reduce costs through a common network infrastructure for voice and data. In many cases, enterprises implementing VoWLAN are doing so as an extension to wired VoIP systems. A company, for example, can equip the majority of the employees with a wired VoIP desk phone, and VoWLAN handsets are given to the employees needing mobility. Certainly the benefit of going wireless is that users can carry their phone with them throughout the facility, which enables them to respond faster to customer needs and functions within the company. The use of VoWLAN phones also eliminates the costs associated with rewiring telephone lines when employees change offices.

Enterprise executives making the decision to spend money on the necessary hardware and services need solid numbers before committing funds. An issue with deploying VoIP, and especially VoWLAN, in enterprises, however, is accurately predicting ROI. Assessing the returns a company will achieve by enabling faster response to customer needs, for example, is difficult. A company must be capable of achieving significant productivity benefits before moving forward with a VoWLAN deployment.
