The Delivering Lync Real-Time Communications Over Wi-Fi white paper is now available from the Microsoft Download Center. This white paper describes how Lync 2010 communications software, and previous releases, Office Communications Server 2007 R2 and Office Communications Server 2007, can be successfully implemented over wireless local area networks (Wi-Fi), even though these workloads have not yet been validated with voice and video (real-time media) over wireless networks.
This overview of issues and mitigations helps ensure a high-quality voice and video Lync experience for all users. To optimize the wireless infrastructure, particularly for real-time media traffic, you’ll find details regarding Wi-Fi (WLAN) technology, configuration settings, and optimization. In addition, this white paper presents deployment recommendations and evaluates typical enterprise, public hotspot, and home Wi-Fi deployments for real-time bidirectional media quality.

Wi-Fi connectivity is ubiquitous, and users expect to find Wi-Fi access in the office, at home, in public hotspots, in hotels, and on the road. However, the Quality of Service (QoS) in Wi-Fi varies widely, ranging from the ability to support basic email sync and web traffic, to the ability to support of a full range of multimedia applications and real-time communications.
This deployment guide discusses different usage scenarios of wireless connected devices, coverage, capacity, and QoS aspects, specifically for delivering real-time communication workloads, such as audio, video, and application sharing. You’ll also find deployment recommendations for enterprise, hotspot, and home Wi-Fi deployments, and a full discussion of issues and mitigations. Finally, the extensive appendix provides a detailed overview of legacy, current, and future Wi-Fi standards, Wi-Fi frequencies, Wi-Fi security, and Wi-Fi WAP handover and resource management.
By successfully deploying Lync 2010 over wireless networks—optimizing your wireless infrastructure for real-time media traffic, prioritizing types of usage, preparing for specific scenarios, and applying appropriate mitigations—you can help to ensure the best possible Lync 2012 experience for all users.
