Watch the full OnDemand Webcast: http://bit.ly/wirelessnetworkdesign Wireless networks are extremely flexible and cost-effective, but they are also highly complex, especially when the scale of the network is large. Wireless networks can no longer "grow organically". They require very careful planning, including a specific design that is verified and possibly modified based on empirical data before wide-scale implementation. They require rigorous testing prior to roll-out to ensure that the specified design achieves the desired goals. They require instrumentation for ongoing analysis and testing, immediately after roll-out to again ensure that design assumptions are correct, and throughout the entire lifecycle of the network, as even the best design is not fool-proof and detailed troubleshooting will be required along the way to properly manage the network. The best approach is to use an integrated set of products that work together to address the entire lifecycle, from preliminary design to live network monitoring to detailed troubleshooting and analysis. This is exactly what the joint solution from WildPackets and Ekahau achieves. This web seminar will walk you through the entire life cycle, using real products to address each step of the process. In this web seminar, we will cover: - Wireless network design and verification - Pre-deployment analysis - Real-time network analysis and troubleshooting - Managing expanded usage What you will learn: 1. How to use site survey software for design and verification 2. How to use network analysis software for monitoring and troubleshooting 3. How to use spectrum analysis software to confirm cases of interference

9. The Importance of Design

10. Example – Purdue University "The management of our wireless network, when you boil it down, is three people. It's three busy people, but not three suicidal people." - Scott Ksander, Executive Director of Networks and Security 6,000 802.11n APs, 265 buildings, 10,000 users Using a controller-based architecture is a must Uses Cisco software for centralized monitoring but requires specific trouble-shooting tools for the field 11n is a must – Purdue learned the hard way that large lecture halls with 802.11bg APs could not tolerate 600 students logging in at the same time Source: http://searchnetworking.techtarget.com/news/article/0,289142,sid7_gci1373978,00.html
