Watch the full OnDemand Webcast: http://bit.ly/platformvpoints With 802.11n ratification a distant memory, news regarding this giant leap in WLAN capability has also waned. But while 11n has quietly receded into the media background, WLANs have crept out of the cocoon of the data-only world and taken flight as full-fledged networking platforms. From dedicated 802.11 communication systems to generic voice and video over wireless with the explosive availability of smart phones, 802.11n is driving a major shift from locally available point solutions to widely distributed, highly available access for all types of applications. Technological advances typically highlight new technological challenges, and this quiet revolution is no exception. Networks, devices, and applications all need to be monitored and managed. Mobility introduces previously unconsidered consequences. The network topology constantly changes as users access and exit the network. New devices with new capabilities crop up almost every day. This web seminar will analyze this wireless metamorphosis with a focus on addressing these key technological challenges. In this web seminar, we will cover: * Wireless trends * The Wi-Fi lifecycle * 802.11n as a driving force * Management layers for complex wireless networks What you will learn: 1. The importance of careful Wi-Fi design and planning 2. How to use 802.11n to your advantage 3. How to dissect and address your wireless management needs

3. Platforms Hardware PlatformA group of compatible computers (computing devices) that can run the same software (firmware). Software PlatformA major piece of software, as an operating system, an operating environment, or a database, under which various smaller application programs can be designed to run. PlatformA horizontal surface or structure raised above the level of the surrounding area. http://dictionary.reference.com/browse/platform

4. Wireless Trends

5. Trends to Watch Blurring the lines – Wi-Fi and Cellular Wi-Fi complements cellular Voice Enterprise – moving from proprietary to standards-based Voice handoff Fitting 11n into the design Consumer devices in the enterprise The rebirth of the smart AP Net Neutrality – “Freedom to Access vs. Access Itself” QoS pricing? Tethering

6. Trends to Watch (cont.) Wi-Fi certification Wi-Fi Direct (P2P) Best of What's New 2010 designation from Popular Science Enables devices to connect, share, sync, print, and play - when, where and how users want Hot-spot certification – truly secure hotspot connections? Higher throughput from new spectrum allocation 60GHz Very High Throughput 5GHz NOT on my list – Consolidated network management

7. The Wi-Fi Lifecycle

9. Excessive interference

10. Rogue APs, Broken APs

11. Coverage holes / leakage

12. Plan for added capacity or coverageSee network trouble spots and find corrective measures See the impact of added access points or new technologies Define applications to be used Define areas to be covered Find locations for the APs Determine AP configurations Find optimal antennas and their alignment See the network coverage and performance prior to depoyment Copyright © 2011 Ekahau.

13. 11n – A Driving Force

14. 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

15. The Real World at Liberty University Multi-channel, IP-based video (IPTV) over wireless Provide roaming students with universal access to multi-channel video Delivery of 15 live TV channels Liberty's campus channel as well as ABC, CBS, CNN, ESPN, FOX, NBC, and a range of other broadcasters Serves 46,000 local/remote students and 2,600 FTEs Network includes more than 770 Aruba 802.11n access points Source: http://www.marketwire.com/press-release/Liberty-University-Launches-Campus-Wide-Wireless-IPTV-Using-80211n-Wi-Fi-From-Aruba-NASDAQ-ARUN-1069662.htm

16. Designing and Planning

17. Wireless Network DesignNo Longer An Option Visual, Enterprise-grade Wi-Fi toolkit for 3D Network Design Deployment and Verification Troubleshooting Created for IT administrators / managers and wireless professional services persons For anyone dealing with a Wi-Fi network of over 10 APs Software application, runs on Windows laptops (XP/Vista/7 32/64bit) Supports 802.11n, and 802.11a/b/g Copyright © 2011 Ekahau.

19. The Wireless Management Onion

20. Spectrum RF intensity (the higher the more intense) Momentary RF intensity (blue = max, green = avg) A wireless camera was first turned off, then switched on to cause an RF havoc Find issues caused by non-802.11 devices, such as microwave ovens, wireless cameras, motion detectors, and Zigbee. RF activity over time (bottom is now, top is 2,5 minutes ago) Wi-Fi Channels 1-3 are mostly affected by the device Copyright © 2011 Ekahau. All Rights Reserved

26. Availability Must distinguish between APs and wireless adapters “NxM” = 3x3 is pretty easy to find Both for APs and wireless adapters 3x3:3 is difficult to find Look for 450 MHz throughput – not many out there APs are a bit easier to find Wireless adapters are much more difficult to find Form factor is also an issue PCIe cards (internal laptop adapters) will be first to market USB devices coming slowly – power is an issue in “:3” devices
