Colubris Networks, the maker of fat APs, introduced support for voice over Wi-Fi: The new system will support SpectraLink's voice over Wi-Fi solution. Colubris is touting its ability to isolate voice and data services so that each can have its own security parameters and quality of service profiles. The company says that previously companies would have to either resort to the lowest common level of security or deploy separate networks for each application. However, a number of WLAN switch vendors support voice and enable the separation of traffic based on the application. Voice traffic is often treated differently than data traffic because most voice over Wi-Fi handsets don't support VPNs. Enterprises that want to secure data transmissions using VPNs must treat that traffic differently than voice traffic.
