 Wireless Voice over IP has become an increasingly attractive wireless network application. It also happens to be a kind of litmus test for inadequate network design and performance. No other network application suffers so noticeably from poor performance. Wireless VoIP as a networked application introduces unique requirements and stresses on a WLAN design.
Wireless LAN’s designed to support more traditional devices and applications often fail to meet the requirements of Wireless VoIP applications, leading to unacceptable performance. In addition, VoIP also requires that the network extend into areas generally neglected when deploying data-only WLANs. Areas such as bathrooms, staircases, and elevators, which are all valid areas for a voice application, usually receive only minimal coverage, if any, in traditional WLAN deployments.
Wireless VoIP devices that rely on voice recognition for operation are even more susceptible to poor voice quality. Inadequate voice quality impedes a user’s ability to interact with the device making it impossible to place a phone call or even log into the device.
Why is VoIP different?
Few network applications dictate WLAN design the way VoIP does. Common networked applications such as email and web browsing have mechanisms to deal with problems like network latency, and often these problems go largely unnoticed by users. However, when network problems are present with a VoIP application they are audibly detectible as poor voice quality or result in dropped and missed calls. Problems which are simple nuisances for wireless laptop and PDA users become critical barriers to VoIP usage.
What does Cumulus do differently?
We focus first on your needs and goals, then we design the solution around them. We know the products that are available and understand their strengths and limitations. We also know that a wireless network design needs to go beyond the infrastructure. With wireless clients ranging from PC's to cameras to phones, planning for the wide range of security, performance, and management capabilities is equally critical. No matter the scale or complexity of the project, our first step remains the same, a thorough and well thought out examination of your specific needs. Our consultants will work with you to develop your business and security needs into a set of technical requirements. These requirements provide the benchmark by which network designs and infrastructure devices will be measured.
