1 Wireless Without Compromise! Flemming Harvad Technical Director EMEA

2 2 Meru Networks Company Overview >Founded in 2002, Sunnyvale, CA, USA Operations in North America, APAC, EMEA >NASDAQ Listed – “MERU” >Mission: Deliver Wireless like Wire™ experience to the enterprise Virtualized Wireless LAN innovation >3,500+ customers in 44 countries worldwide >Category Leadership Enterprise 802.11n solutions pioneer Wireless VoIP, Video/HD video Converged applications at scale Device and user density, seamless mobility, QOS Fixed-Mobile convergence Enterprise WLAN service assurance >Deloitte - 2010 Technology Fast 500 Rankings Meru Networks Ranked the nr. 25 overall and nr. 5 in IT industry – Worldwide.

4 4 Historical Deployments Micro-Cell: Pretty much everyone’s deployment today The future…. Meru -Casual use network (conf rooms) - Individually Managed - Multiple Points of Security + Centrally Managed/Secured -Complex RF Planning - Unstable RF by design + Industry leading TCO advantage + Very simple deployment + Switch-like experience Ok for Network of ConvenienceOptimal for Wireless Edge Lets look at how we got here and why…..?

5 5 Pre-802.11 Access Evolution of Wireless LANs Fat Access Point Standardization Microcell Centralization * Gartner Classification Virtualized Traffic Optimized 1990’s 1st Generation* Virtualized Traffic Optimized 2000 2nd Generation* 2005 3rd Generation* Today 4th Generation*

6 6 Meru Virtualized Meru’s Virtualized WLAN Virtualize + Optimize the RFResources Legacy Microcell Hub Switch Pooling >Single channel APs are like light bulbs >Transparent mobility Clients see no handoff >Layered Channels Every MHz everywhere Partitioning >Virtual Port Dedicated AP per device >Airtime Fairness Network guarantees each device its fair share of the air >Network Control

7 7 802.11 Technology Implications RF Planning is Complex Clients are in Control Slowest Client Dominates Uplink Chokes Downlink

8 8 802.11n Technology Implications Unpredictable Coverage Trade off Fairness & Efficiency 2.4bg/5n RF Plan Differences Operational Complexity 11abgn Tx Power Power Save Roaming Antenna Spatial Streams Antenna Type Channel Width MIMO-PS Aggregate Window Aggregate Size MCS Rates

9 9 Total Bandwidth at Peak 5 8 11 1 Contention Loss Contention Loss Other AP Performance Meru AP Performance Active Users Per AP Other WLANs Meru Number of Active Users Peak Aggregate Throughput No upstream client flow control creates contention in the network Hub vs Switch – No fairness to anyone….

10 10 Client sees only one cell, no handoff Infrastructure maps client to best AP at any time Seamless mobility regardless of device, driver, chipset, settings Zero loss mobility for voice and video – only with Meru Only Meru Provides Zero Handoff

11 11 Deploying APs is like putting Light Bulbs Micro-Cell Channel Planning Mandatory RF Unstable by Design Needs hand tuning Almost impossible to optimize 2.4 and 5GHz simultaneously Virtual Cell/Single Channel No Channel Planning Required Network Invariant No tuning required Holes patched like light bulbs

12 12 Deep Flow Inspection based Automatic Provisioning Application-Aware Flow Detection Voice prioritized, rate limiting controls Video prioritized, rate limiting controls, client and up/down fairness Data best effort, elastic client and up/down fairness Airtime Fairness Over-the-air QoS

13 13 Optimum Video, Voice Delivery  Virtual Port -Per device sandbox: switch-like experience -Seamless mobility: applications without disruption Voice prioritized, rate limiting controls Video prioritized, rate limiting controls, client and up/down fairness Data best effort, elastic client and up/down fairness  Air Traffic Control -Client/Class Airtime Fairness: predictable service -Uplink/Downlink Fairness: highest client density -Contention management: peak channel efficiency  Application-aware Packet Processing -Prioritization based on application -App-aware scheduling: voice and video in synch -App-marking based differential treatment: best user experience under high load -Admission Control and load balancing  Multicast Group Management -Control broadcast suppression -Per-station group management -Multicast to unicast conversion: optimal for 11n

14 14 Simplified Helpdesk Troubleshooting 1. Go to specific Controller 2. Go to specific Station 3. Go to specific location

15 15 Rewind & Review Network State in Past Slides back in time

16 16 Meru Single Channel Architecture: Neighborhood Watch for Service Assurance >Single Channel only architecture for service assurance No service disruption No channel change

17 17 Multi-channel Microcell: Neighborhood Watch Not Possible x x x x x x >Microcell infrastructure cannot perform service assurance AP can’t reach neighbors; must change channels and disrupt service

18 18 How can I see my network health? Can I proactively detect problems before they impact the users? How good is my wireless network coverage? Can I assess security health of my network? How can I troubleshoot client connectivity problems? How can I detect interference from microwave ovens, cordless phones? How can I provide compliance reports?
