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
