In the survey conducted for Steve\u2019s 2003 VoIP State-of-the-Market Report, several questions were asked that for various reasons didn\u2019t make it into the final published results. But we promised that we would continue to share some of these results with you.One of these questions was, \u201cHow important is each of the following applications in your VoIP deployment?\u201d There were 13 sample applications - plus \u201cother\u201d - for respondents to choose from. We then determined the most important applications by taking the number of respondents who chose an answer of either \u201cVery Important\u201d or \u201cExtremely Important.\u201dWe didn\u2019t find it surprising that unified messaging topped the list. But we were a little surprised that interactive voice response (IVR) came in second, and more than a little surprised that wireless LANs (IEEE 802.11) came in third. In fact, WLANs even edged out desktop collaboration (CTI and SIP), desktop voice\/video conferencing, and the IP contact center.Now admittedly we\u2019re not necessarily claiming that everything listed as an \u201capplication\u201d makes for an apples-to-apples comparison. Nevertheless, the message is clear. Two of the hottest areas in our industry - WLANs and VoIP - are looking for synergy.This also raises some interesting questions, not the least of which has to do with bandwidth management. Making VoIP work in a LAN is a no-brainer when you\u2019re throwing switched 100M bit\/sec Ethernet and Gigabit Ethernet at the problem. Squeezing the same performance out of shared, limited-bandwidth radio channels can be a bit more challenging, to say the least. There\u2019s only a limited spectrum available, so voice could be actively competing with bandwidth-hungry data applications.Next time we\u2019ll continue this discussion by looking at wireless handsets for use with VoIP.
