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

• 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.
• 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
• "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
• Security protocols and policy• Rogue APs and clients• Ad-hoc networks• Wireless security attacks• QoS configuration and use• Signal strength• Dropped packets and retries
• Tracking wireless packets onto the wired network
• QoS configuration and use• VPN/MPLS• Application vs. network latency
• 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
