2 Continue the Trends that have been highlighted in past research The Market now sees dualradio 802 11n access points being deployed for less than The Market now sees dual-radio access points being deployed for less than $350, and single-radio designs for considerably less than $300 Access points with are now only being deployed within an enterprise organization as a bridging strategy to the newer, faster and more-functional ggggy,access points. The adoption of and the migration into the enterprise continues, but the movement toward the all- Wireless enterprise still has to overcome hurdles (whether real or perceived) before it attempts to become a standard for edge-of-the-network connectivity The Market and technology continue to move toward the coveted carpeted enterprise spacespaceSource: Gartner's Research 2011 Trends and Challengesg Mobile staff High availability High availability Increasing bandwidth demand Convergence of financial systemsConvergence of financial systems IT & Mobile Devices IT Process and Resourcesddi if bl&ki Standardization of cable & networking Real-time Monitoring of all IT systems VoIP VoIP Wireless Overlays More information requires greater communicationqgTrends and Challengesg Physical Connectivity Issues Limitation of Wireless Signals Older Facilities, Lower Floors and Basement Areas Coverage Gaps Technology Connectivity Issuesgyy Supportable Technology (Smart Phones, PDA s, Tablets, etc.)

4 With an client and router, you will find a Wireless experience that outpaces all previous Wireless technologies. It has real-world throughput that clocks in at 160 Mbps or faster seven times faster than older networks At 300 feet, performance plummets to 1 Mbps. An network operates at up to 70 Mbps70 times faster than 802 11goperates at up to 70 Mbps 70 times faster than The key to this speed is MIMO (multiple input/multiple output) which uses multiple antennas to send and receive digital data in multiple simultaneous radio streams, thus multiplying total performance ,pygp The bottom line With , you can share data, photos, stream video and music among multiple devices faster and at greater distances than ever beforeNorth America Wireless LAN Market Bandwidth per Enterprise UserBandwidth per Enterprise User2009 2010 2011 2012 2013 2014 2015 North America Enterprise Access Point Units (000's) , , , , , , , , Total2, , , , , , , ge Ba ndw idth per Unit (Mbps) ,003 Weighted Average (Mbps)1632303656317589001,003 Users per Access Point9999999 Average Bandwidth Available per User (Mbps)1927437489106118 Source.

7 The Internet Your routed and switched network Personal computers They re all shining examples of where distributed tih d th l tdcomputing had the last Challenge of IntelligenceggRhetorical Why would you want only one device performing a set of functions when you could have hundreds, or even thousands of devices performing those functions simultaneously?even thousands of devices performing those functions simultaneously?Example: You could have one controller doing all of the processing tasks for 1,000 APs or you could have 1,000 APs processing tasks for themselves. Which scenario offers more computing power? Which is more scalable? Which is more resilient?Which is more scalable? Which is more resilient? Of course, the first argument against the distributed approach is cost, but since controllers arrived on the Market in 2003, Moore s law has been hard at work reducing AP component prices and increasing computing powerprices and increasing computing power.
8 Today, high-powered CPUs and high-speed memory chips are commodities that can be purchased very inexpensively Hence a scalable and robust cabling infrastructure becomes highly important and a Hence, a scalable and robust cabling infrastructure becomes highly important and a technological necessity!In this paradigm shift, it s now the controller s lack of computing power and high cost that is being called into question by system integrators and customers not the cabling plant!called into question by system integrators and customers not the cabling plant!Intelligence and ReliabilityIntelligence and Reliability OxymoronOxymoron?? With Wi-Fi network reliability being repeatedly touted by analysts as the most important criteria among customers, the question looms large, hldhilhili bili ? Why would a customer accept anything less than superior reliability? Every Wi-Fi infrastructure vendor is now pitching their solution as the most reliable (you ve probably heard phrases like WiFi as a Utility ) even though the architecture(you ve probably heard phrases like, Wi-Fi as a Utility ), even though the architecture on which most vendors have built their solution is far less than dependable It has now become imperative to have a cabling plant that provided QOS, Scalability as well as Reliabilityhhl dhbll lbllf/ Which leads us to the question, is Category 5e cabling now slowly becoming pull string for Category 6/6A?
9 Wireless will always have some form of dependence upon a wired network---regardless of bandwidth!
