Combining VoIP with 802.11 wireless LANs to create a wireless telephone system to Offices is an emerging market segment. VoWIP enables businesses to leverage their wireless LANs to add voice communications enabling companies to deploy and manage voice and data over a single wireless backbone.

A significant benefit of mixing telephone traffic with data on a WLAN is to provide mobility and make use of a common infrastructure. The support of a common system for both data and voice traffic is generally simpler and less expensive than two separate entities.

 

It is worth upfront time and effort to prepare for a voice over wireless LAN (VoWLAN) deployment. Otherwise, if your VoWLAN implementation doesn't deliver the call quality your users have come to expect, it will be judged a failure.

Analysis of the radio frequency environment is essential in planning a successful VoWLAN.

 

Meeting call quality goals requires maintaining a consistently strong signal throughout your facility. The first step is a comprehensive analysis of your facility's radio frequency (RF) environment, which requires:

• Tools designed specifically for the task.
• Personnel with the expertise to understand the results.

Any wireless deployment should include an RF analysis, but a WoWLAN deployment also requires the analysis to cover areas of the building that may not have been considered in an earlier wireless deployment (e.g. stairwells or even restrooms), because voice users expect to be able to make or continue calls from anywhere in the building.
