(American Hotel & Lodging Assn.)
Wi-Fi’s ubiquity means greater
ROI and productivity; VPN,
managed networks, and up-to-
date hardware enables robust
enterprise level security

16. 2007 Outlook: Wi-Fi in the Enterprise
Opportunities and Challenges
• Not just for laptops anymore: Increasing
adoption of Wi-Fi-enabled handhelds,
phones, etc.
– Improves mobility and productivity
– Makes deployment more complex
• Voice as “killer app”:
– Cost savings very compelling
– Mobile convergence will further enable the market
• Intelligent switches and robust site survey/network management
solutions becoming more widespread
– Readying the enterprise for next-generation Wi-Fi
applications
• Balancing upsides of single-vendor deployments vs. getting
locked in to a proprietary solution without broad interoperability
• On the horizon: 802.11n, mesh, and video

19. Deploying Voice over Wi-Fi:
Key technical considerations to maximize ROI
Issue Recommendations/Considerations
Coverage and Pervasive coverage – lobbies, stairwells, balconies, etc.
range
Denser AP configuration (~30002 feet)
Site survey to look for “noise” and plan capacity
Quality of Require WMM™ certification for packet prioritization
Service
Limit concurrent users to <7 per AP
Partition voice traffic to 802.11a 5 GHz band only
Security Require WPA2™ security with EAP support
Partition voice users to separate virtual LAN
Power Mgt. Require WMM™ Power Save certification for all clients and APs
Interoperability Even with single-vendor AP configuration, multitude of clients, so require
interoperability verification
19

20. Wi-Fi CERTIFIED and Voice
applications
• In place now …
– Certification of handsets for core interoperability and security
– WMM QoS and WMM Power Save to prioritize traffic and conserve
power
• Voice over Wi-Fi Enterprise Program: early 2008
– Performance testing of voice-related characteristics
in client devices and access points
• Prioritization, mobility/roaming, call capacity,
voice quality, etc.
– Protocol adherence testing to ensure
interoperability
• Power saving, security, resource
measurement, etc.
– Includes radio resource management and
fast roaming
20

21. Testing converged Wi-Fi / Mobile phones:
RF Performance and interoperability
• ~85+ converged phones have been Wi-Fi CERTIFIED for core
802.11 a/b/g interoperability and WPA™ security
– Further revisions to this program
ahead in 2007
• WFA and CTIA jointly released a test
plan in 2006 for RF performance mapping
– Comprehensive set of
measurements to carriers
evaluating converged handsets
• Other challenges currently under exploration:
– Handoff between Wi-Fi and non-Wi-Fi
networks
– Power consumption mapping
– Bluetooth coexistence
21

22. 802.11n: Next-generation Wi-Fi
• 802.11n will bring up to 6x throughput and improved range for Wi-Fi networks,
along with next-generation Quality of Service features
• WFA plans to introduce a certification program for pre-standard IEEE 802.11n
products in the first half of 2007 to help ensure interoperability for a baseline
set of features in the short term
• The Wi-Fi Alliance plans to certify products based on the final IEEE
802.11n standard when it is ratified, supporting what we expect to be a
larger set of features and a fully reviewed and interoperable standards-based
solution
22

23. 802.11n: Coming soon to an
enterprise near you
• 802.11n benefits the Enterprise with higher data rates and the
ability to support more concurrent users
• Next-generation Quality of Service for Voice and video
applications
• Better whole-building coverage
• Combined with mesh network
architectures, these will be the
most cost-effective, self-healing
Wi-Fi networks available
• Backward compatibility with
802.11a/b/g gear
• Wi-Fi CERTIFIED products
compliant with full 802.11n standard
expected mid-2008

24. Security Update
Wi-Fi CERTIFIED ™ m ake s it Wi-Fi.

25. Wi-Fi Security Update
• WPA2 has been mandatory since March ’06
– Government-grade security
• Security Marketing TG recently re-formed to:
– Develop IEEE 802.11 TGw (Protected
Management Frame) MRD and launch plan
• IEEE 802.11w Amendment provides
protection for action and other types of
management frames
– Review market requirements for EAP test bed
methods, propose updates if needed
Always specify Wi-Fi CERTIFIED in your RFPs to ensure you
get the best-available government-grade security in your Wi-
Fi deployments
25

26. Introducing Wi-Fi Protected Setup™:
A new solution easing security setup in
home networks
• Wi-Fi Protected Setup is an industry-wide optional certification
program provided by the Wi-Fi Alliance
• Wi-Fi Protected Setup helps ease the process of setting up and
protecting a home or small office Wi-Fi network.
– By pushing a button or typing a short PIN, consumers can
connect computer equipment and
home entertainment gear
to a Wi-Fi network and enable
security protections more
simply than ever.
Wi-Fi Protected Setup
means more remote
workers will have their
home networks secured
26

27. How Wi-Fi Protected Setup works
• When a consumer brings home a new
Wi-Fi CERTIFIED Wi-Fi Protected Setup
device and turns it on, the network
detects its presence automatically
• The user is prompted to either enter a
PIN or push the button
• The network name and encryption
information are securely transferred to
the device
• A variety of devices can support Wi-Fi
Protected Setup, from PCs and routers
to cameras and phones
• New client devices can easily join an
existing Wi-Fi Protected Setup network

29. Summary
• Wi-Fi is everywhere, in the enterprise, on the road and
at home
– Ubiquity drives greater productivity gains and ROI
• 802.11n will make it easier to deploy data and voice
more cost effectively, across multiple freq bands
• Mesh and video are important developments to watch
• Wi-Fi Protected Setup means more home networks will
be secured
