Why Do Customers Choose Meru Over Other Solutions?
1. Better Performance and Scale Predictable performance and fair access to clients Improved performance in mixed 802.11b/g networks Toll-quality Voice Improved Mobility / Zero-Handoff
2. Lower Costs of Deployment and Operations● Reduced need for site-survey, channel planning● Less APs to deliver same application performance● Lower operational complexity
3. No Compromise Security No tradeoff between security and application performance Security policies based on application, location Air-Firewall – blocking rogues, protecting transactions over the air
4. Best Architecture for the Future Supporting new applications: voice, video Scaling capacity with 802.11 a/b/g Migrating to 802.11n
Air Traffic Control™ Technology:Virtual Cell – Single Channel Spans
APs act as a coordinated system rather than each AP acting as an individual wireless hub
● All APs on the same channel have the same BSSID (wireless MAC address)
● Client only sees only one AP on a channel
Benefits● Infrastructure controlled
o Best AP assignmento Handoff
● No handoff from Client Perspective
● Load balancing between AP’s

Air Traffic Control™ Technology:Application-Aware Optimization
I heard of Meru’s approach to client density and improving 802.11g & 802.11b performance and was intrigued to see if this would solve our issues. The Meru system was deployed throughout Jamrich Hall supporting 800 students simultaneously.”Dave Maki Dir. Of Technical Services N. Michigan University

Ease of Set-up and UseSingle Channel Layering
Meru is bucking the trend with unique offerings that reject conventional architectural and deployment models. Meru’s single channel-channel architecture makes deployment easier while promising greater scalability, enhanced roaming and coordinated over-the-air quality of service. Dave Molta, November 2006
Ease of set-up and use● No traditional channel surveys● No Access Point power adjustments
or spacing limitations● No channel configuration● No voice QoS parameter
adjustments● Plug and play out of the box● Extend the network without re-
planning
Authentication & Encryption Layer
Secures traffic for valid flows Protects the identity and location
of valid users Key Features:● WPA, and WPA2, 802.1x, 802.11i● MAC Access Control Lists (ACLs)● Encrypted management traffic (AES,
3DES, SSL)● Multi-factor authentication and policy
control
Authorization & Isolation Layer
Captive portal for guest-access; traffic separation based on type of user
Access control decisions with NAC/NAP● In partnership with leading NAC vendors:
Microsoft NAP, Cisco, Juniper, Consentry, Bradford, Vernier, Lockdown
● Access determined based on user’s: access rights, location, client security state
● Example: - Objective – laptops with only the latest virus
protection software allowed network access.- Remediation – non-conforming clients placed in
quarantine VLAN for SW updates
Wireless IPS Layer
Rogue Detection and Mitigation

Supporting Legacy clients with 802.11n in 2.4GHz
2.4GHz is integral to any legacy-supporting scheme You need to implement 802.11n in 2.4GHz as well
● Most external client cards support only 2.4GHz 802.11n only
Virtual Cell allows a dedicated channel layer for 802.11n-only without disturbing legacy coverage
AP302 enables deployment of abg clients today, with upgradeability to 11n through software upgrade
