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).


Warehouses involve a host of functions where VoWLAN systems can provide significant benefits. Clerks end up being scattered throughout the warehouse facility, which can be quite expansive, and communication with other clerks and managers is essential to perform various functions. In most cases, having the clerks and managers meet face-to-face to communicate is not practical. In fact, being able to even find each other is often not possible, due to the numerous rows of bins and products. For example, an order may come in for the shipment of a particular item to a customer. Rather than waiting for a clerk to return to the main office, having the shipping department call a clerk directly and have him pick the item is much faster and more productive.

As with retail environments, many warehouses already have existing wireless LANs. However, because these wireless networks primarily support relatively low-performance bar code solutions for implementing inventory management functions, the wireless LAN may not have enough capacity to support a large number of VoWLAN phones. A company must analyze the wireless LAN and ensure that adequate data rates, signal strength, and roaming exist to support wireless voice applications.
