With the introduction of Intel^® Centrino^® mobile technology, today's mobile notebook is an advanced communication platform with integrated wired and wireless technologies. One of the important communication technologies that has been making excellent progress in the industry is Voice over IP (VoIP). The Centrino notebook augments ingredient technologies to improve the VoIP experience for the end user, resulting in enhanced productivity.

Recent advances in VoIP applications, protocols, infrastructure, equipment and peripherals have resulted in IT departments of medium and large businesses becoming interested in deploying this technology. The goal is to have the business road-warrior communicate in a seamless way both inside and outside the enterprise. Also with the advancements in the Internet Protocol Private Branch Exchange (IP PBX) infrastructure, IT shops have been racing to replace their legacy, cumbersome Time Division Multiplexing (TDM) PBXs with easy-to-manage and more flexible IP PBXs. The impediments to such deployment have been the ability to deliver the expected Quality of Service (QoS) for voice calls, call privacy, and ease of use of VoIP applications.

In this paper, we present the platform ingredient technologies that Centrino offers this year (2006) in order to deliver a best-in-class VoIP experience over wireless and wired networks. This includes Intel's QoS solution for enhanced VoIP experience over Wireless Local Area Networks (WLAN), Intel's Array Microphone for better open audio, Intel's Integrated Performance Primitives (IPP) libraries for improved overall VoIP experience, and enabling the use of Bluetooth* headsets for hands-free VoIP.
