  9. 9. Why are Schools Choosing Meru WLAN? Reliability, Performance, Simplicity, and Cost "When a cart with 25 laptops rolls into the classroom, everyone expects to log on immediately. With our old system, half the class often wasn't able to authenticate and get access. Now, with Meru WLAN everyone can connect at once, and our wireless network is incredibly reliable." “Meru's Air Traffic Control Technology™ also gave us switch-like performance with no co-channel interference, even when we installed additional APs to fill coverage gaps. And because with their single- channel approach there's no need for channel planning, it's easy for the BCPS technical staff to manage." “The simplicity of the Meru solution and the ease with which we can add access points and change the system made it the best choice for us. We can truly leverage this technology for the benefit of our teachers and students. Our students use laptops and we're using advanced applications such as video streaming across the wireless network to deliver lessons."
  10. 10. Key Wireless LAN Pain Points for Educational Institutions • Cannot connect or connections get dropped Students • Network is slow • Wireless doesn’t work well with video or real-time interactive apps • Getting every student to boot and login cuts into limited class time Teachers • Reliability and speed needed for classroom mgmt and teaching applications • Complex and costly to deploy, time consuming management IT Managers • Providing wireless network access for dense populations of student and faculty in classrooms, libraries, cafeteria, auditoriums • Providing mission critical, converged applications over the wireless infrastructure as part of the school services  Requires a flexible and robust network, deliver next generation education applications of voice, video, and data CIOs  Providing security and communications across a highly mobile student and faculty population  Deliver services within a dynamic academic environment with space constraints • Deliver Unreliable wireless limits ROI on school technology School/District investments (computer carts, labs, etc) • Funding/refresh cycles can’t keep up with technology
  11. 11. If only wireless was as easy wired… Wired Edge: Stackable Ethernet Wireless Edge: if using Microcell Simple email and web download ok, Runs all applications but what about other apps? Deterministic performance and Performance and reliability are not reliability deterministic RF tuning and diagnosis is black magic, Well understood “cookbooks” for micro-cell tools ineffective management and diagnostics - can’t tune what you can’t predict Predictable costs and coverage Unpredictable cost and coverage Known formula for increasing Incremental capacity involves unknown capacity and scale and likely costly RF redesign
  12. 12. Challenges for the Wireless Edge How to make wireless work like wire? Challenges Solutions deployment, planning, analysis, Simple changes coverage, performance, Predictable mobility connectivity, performance, Reliable diagnostics cost effective growth as Extensible devices, apps evolve
  13. 13. Meru Innovations -Technology Cornerstones Abstract Stacked Channel Span Virtual Cell Scale Linear capacity growth physical Capacity network and Per pool RF Area resources Optimize Provide switch application level control Performance over each client Virtual Ports Port level control Application Aware Network
  14. 14. Wireless LAN Virtualization: Phase I Consolidation Meru Virtual Cell: Pooling of RF Resources into a Single Entity  Wireless Coverage like “light bulbs” - Where there is not enough “light”, add more access points. - No disruption of the existing network or rewiring of surrounding “lights” - Adjacent “lights” blend together uniformly - If one “light” goes out, the room still has some light without interruption Virtual Cell eliminates physical resource Seamless mobility for free; boundaries Spatial growth without disruption
  15. 15. Wireless LAN Virtualization: Phase II Partitioning Meru Virtual Port: Per-Device Extension of Virtual Cell  Introduces “switch port” control and granularity to wireless - One device does not bring down the others - Eliminates uncontrolled sharing of network resources  Each client appears to get its own dedicated AP throughout the network Virtual Port provides abstraction of network per device Leverages Virtual Cell mobility and predictability
  16. 16. Microcell vs Meru’s Virtual Port Analogy Microcell: All users share the same Meru Virtual Ports: Each users has road, no prioritization, experience their own road and their own determined by other traffic experience
  17. 17. WLAN Virtualization … and its benefits Virtual Cell Pool RF Resources • Lowers cost of operations • Grow as you go • Reliability Partition RF Resources • Seamless Mobility Virtual Port •Network is in control •Highly Predictable •Increased Security Customize RF Resources •Improved Management & Diagnostics Network is customized per client •Port-level control •Port-level services and access

  27. 27. Meru Addresses Education’s Most Challenging Wireless Issues Meru Approach Other Approaches Deployment • Single-channel eliminates complex and costly  Traditional microcell deployment requires heavy RF RF channel planning channel planning and power management of access • No need to re-plan the entire network to points that only last until the next move/add/change accommodate Moves/Adds/Changes User Density • True Air Time Fairness algorithms ensure that  Random access prevents large number of users from all clients get high-quality performance accessing the network efficiently—only a few users get desired performance while other experience delay and erratic quality. The more clients, the worse the performance Real-time • Virtual Cell eliminates co-channel • Clients make roaming decisions between APs on interference, coordinating all access points to different channels with Microcells. Due to air time Applications behave as a single, distributed access point, contention, roaming times are highly variable, ranging Support supporting seamless roaming for real-time from 100ms to seconds applications • No upstream QoS limits support advanced • Supports up-stream and down-stream QoS applications required by wireless voice and video Investment • Full backwards compatibility for a/b/g/n • Limited backwards compatibility—single B client can • Built-in scale with channel layering capability, impact performance of G clients and same is true for Protection allowing customers to double/triple network a/b/g clients in 802.11n networks capacity by simply adding APs to high-use • Difficult to scale due to inherent tradeoff between areas coverage and throughput—AP cells must be reduced to support greater throughput but as AP cells get smaller, channel interference among APs increases
