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 Convenience Optimal for Wireless Edge

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

No upstream client flow control creates contention in the network

Hub vs Switch – No fairness to anyone….

• 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

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

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
