Intel, Cisco: Collaborative Testing of Media-Ready WLAN Solutions
Businesses are rapidly adopting rich-media applications, such as videoconferencing, and on-demand training, on their wired and wireless LANs (WLANs). In the case of WLANs, the bandwidth-intensive, real-time and delay-sensitive nature of video presents challenges that require a robust infrastructure and cl...ient combination capable of providing high performance and uninterrupted service. Cisco and Intel are committed to ensuring the highest level of performance and reliability for business video by working together to test and validate these applications for the beneft of our customers. The objective of this whitepaper is to showcase and validate the media-ready end-to-end WLAN solution that Intel and Cisco provide through two test cases: HD Videoconferencing Mobility and Multicast Video Delivery with Data Co-existence.
The growing use of video applications over WLANs
Videoconferencing enables life-like, real-time communication that enhances many business processes within key verticals such as healthcare and education, and enriches collaboration in any multisite business. By offering HD-quality collaboration tools, many organizations can empower employees to work together across disparate locations – cutting travel costs while boosting productivity and collaboration. Video applications require the WLAN to provide ample bandwidth in addition to seamless roaming for mobile users without compromising security. For bandwidth, Cisco and Intel implemented 802.11n. For seamless mobility –Cisco and Intel collaborated to deliver fast, secure roaming using standards-based WPA2 authentication with proactive key caching.
Another emerging wireless video delivery usage model is one-to-many streaming (multicast) of live or pre-recorded material. This application can deliver training materials or organization-wide information to employees, students or members in an efficient manner. The network requirements of a typical enterprise-class video stream ranges from 1 Mbps to 5 Mbps, which can cause problems over legacy 802.11a/b/g Wi-Fi connections that use legacy multicast techniques and lack quality of service (QoS) prioritization. To address this need, Cisco created VideoStream, which provides the reliable multicast delivery and QoS to enable business-grade video. On the mobile client side, the Intel® Centrino® Ultimate-N 6300 adapter supports business-grade video with dual-band 3x3, 802.11n for up to 300 Mbps data rates when used in conjunction with a two spatial stream 802.11n access point.
