  1. Wireless Without Compromise! • Flemming Harvad • Technical Director EMEA

  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. Lets look at how we got here and why…..?

  5. Evolution of Wireless LANs Today4th Generation* 20053rd Generation* 20002nd Generation* Traffic Optimized Traffic Optimized 1990’s1st Generation* Centralization Standardization Access Virtualized Pre-802.11 Fat Access Point Microcell Virtualized * Gartner Classification

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

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

  8. 802.11n Technology Implications Trade off Fairness & Efficiency Unpredictable Coverage 2.4bg/5n RF Plan Differences Operational Complexity

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

  10. Only Meru Provides Zero Handoff • 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

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

  13. Voice prioritized, rate limiting controls Video prioritized, rate limiting controls, client and up/down fairness Data best effort, elastic client and up/down fairness Optimum Video, Voice Delivery • Virtual Port • Per device sandbox: switch-like experience • Seamless mobility: applications without disruption • 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. Simplified Helpdesk Troubleshooting 2. Go to specific Station 3. Go to specific location 1. Go to specific Controller

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

  16. Meru Single Channel Architecture:Neighborhood Watch for Service Assurance • Single Channel only architecture for service assurance • No service disruptionNo channel change      

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

  18. EzRF Compliance Manager Single Platform, Multiple Services 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? EzRF Visualization Manager Services Assurance Manager Troubleshooting Manager Compliance Manager Spectrum Analyzer Wireless Intrusion Prevention System Network Manager
