Overcoming VoWLAN Challenges
Early, enthusiastic predictions about the success of Voice over WLAN (VoWLAN) have fallen wide of the mark. A few vertical industries are putting the technology to work, but it's made little or no impression on the enterprise and consumer segments. The situation is in flux, however. A number of vendors are enhancing their VoWLAN solutions: adding features, extending their architectures, and adopting new standards. With VoWLAN looming on the horizon (and solutions already available) they don't have much time to get ready for rollouts. It's already clear that IT and telecom professionals will have to grapple with a bewildering array of VoWLAN options. In addition, VoWLAN itself is a tricky technology to implement, especially when it comes to RF planning, mobility and Quality of Service (QoS).
