Aruba is the latest WLAN switch maker to add support for voice over WLAN: It introduced new software that is offered as a free upgrade on Aruba switches. The software offers security by restricting where traffic from voice devices can go. The platform enables handoff between access points in under 50 milliseconds to support voice. Aruba can also locate user devices so voice service on its platform complies with E911 requirements. Aruba also said it is working with SpectraLink, TeleSym, and Vocera to support products from those companies.
WLAN switch vendors are increasingly adding voice capabilities to their products. While few mainstream enterprises are offering voice over WLANs today, they may be making purchase decisions based on products that have the capability in case they want to add it in the future.
