Market Definition/Descriptionp• Standards-based connectivity between access points and devices is no

longer unique• Enterprise organizations must choose infrastructure providers that can

deliver network services (such as voice, video and data) and integrate wired networking products

• At this time, the WLAN market consists of vendors that supply IEEE 802.11 standard networking components that provide mobility to the infrastructure access layer, from the edge of the wired network to the end user

• Vendors have significantly narrowed the performance gap between the divergent wired and wireless environments, and continue to integrate management, security, guest access and planning services

• These solutions have combined wired and wireless functionality, as well as spawned multi-vendor wireless solutions, to provide a solid foundation and continuity in networking infrastructure communications

Market Overview• In today's WLAN market, infrastructure vendors provide hardware out of necessity,

not for differentiation • The availability of reference designs from chip manufacturers and original design

manufacturers (ODMs) continue the trends that have been highlighted in past research

• The market now sees dual radio 802 11n access points being deployed for less than• The market now sees dual-radio 802.11n access points being deployed for less than $350, and single-radio designs for considerably less than $300

• Access points with 802.11g are now only being deployed within an enterprise organization as a bridging strategy to the newer, faster and more-functional 802.11n g g g gy ,access points.

• The adoption of 802.11n 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 spacespace

Trends and Challengesg• In 2011, 802.11n access points with three spatial streams began to be

introduced into the marketplace

• Additionally, three spatial streams provide, in theory, a 50% increase in bandwidth to the link between the user and the AP

• In 2012, 802.11ac and 802.11ad LAN technologies will be introduced, providing more bandwidthproviding more bandwidth

• Are we creating future “bandwidth bottlenecks?”

802.11n for Unparalleled Speed & PerformanceSpeed & Performance

802.11n completely redefines Wi-Fi speed, ushering in a whole new level of network performance.

– With an 802.11n 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 802.11g networks

– At 300 feet, 802.11g performance plummets to 1 Mbps. An 802.11n network operates at up to 70 Mbps 70 times faster than 802 11goperates at up to 70 Mbps—70 times faster than 802.11g.

– 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 , p y g p

– The bottom line – With 802.11n, you can share data, photos, stream video and music among multiple devices faster and at greater distances than ever before

The Edge of Intelligence• There are multiple important facets to WLAN networking,

and a very important one is system architectureand a very important one is system architecture• There are currently three kinds of architecture available in

the marketthe market• Centralized (where products have been)• Hybrid (where most products are today)• Distributed (where most products will be in the future)

• They’re all shining examples of where distributed ti h d th l t dcomputing had the last word.

The Challenge of Intelligenceg gRhetorical Question…

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.

– 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, “ h ld hi l h i li 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 “Wi Fi 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 Reliability

h h l d h bl l l b ll f /– Which leads us to the question, is Category 5e cabling now slowly becoming pull string for Category 6/6A?– Wireless will always have some form of dependence upon a wired network---regardless of bandwidth!

• Every Wi-Fi infrastructure vendor knows that a fully-distributed architecture will win y yout in the end, and because of this, they have begun moving key features into their APs within their latest code revisions

Full Duplex EthernetFull Duplex Ethernet

h d f b l k•When a twisted pair or fiber link segment is used and neither end is connected to a repeater, full-duplex Ethernet becomes possible over that segment

•In full duplex mode both devices can•In full-duplex mode, both devices can transmit and receive to and from each other at the same time, and there is no collision domain

•This doubles the aggregate bandwidth of the gg glink and is sometimes advertised as double the link speed

•The elimination of the collision domain for these connections also means that all the li k' b d id h b d b hlink's bandwidth can be used by the two devices on that segment and that segment length is not limited by the need for correct collision detection
