Aruba will support voice-quality links on office wireless LANs, disputing competitors\u2019 claims that the job needs a whole new architecture."Enterprises are asking for a coherent strategy to introduce dual mode into their networks," said vice president Keerti Melkote. Aruba\u2019s product announcements are part of a three-year plan to meet business demands for converged phones.Aruba will offer WMM, the Wi-Fi Alliance\u2019s specification of the IEEE\u2019s 802.11e standard for Wi-Fi, and traffic specification signaling so that data streams can be tagged as requiring voice quality. The company is also improving its Call Admission Control so calls can be balanced between cells and access points aren\u2019t overloaded.The company also promised two ways to improve battery life on handhelds. Aruba has implemented the Wi-Fi Alliance\u2019s U-APSD specification,\u00a0which lets handsets sleep between sending packets, and it also lets the central mobility controller act as a proxy for the client, handling signals such as address resolution protocol requests, so they aren\u2019t delivered to the handset. "We can increase battery life by\u00a010 times, even for existing handsets," said Peter Thornycroft, Aruba\u2019s product manager for voice.Aruba is also publishing a spec document for voice on Wi-Fi (VoFi) handsets for enterprise use, which should help equipment makers produce devices that make the most of battery-saving and quality-of-service features in the network.The company will also publish an\u00a0application program interface\u00a0for PBX vendors, so VoFi can be added to existing equipment. "We are in the best location to determine when you have moved outside the Wi-Fi zone," said Thornycroft. "We can bridge the two, and scale to thousands of calls, without requiring a PBX upgrade."-Peter Judge, Techworld.com (London)Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
