  2. Agenda • Infrastructure Access Point Positioning • Trilogy 3.0 Hardware • Trilogy 3.5 Software Features • Trilogy 3.7 Planned Features

  3. AP Product Positioning • High End Product (new) • AP 4131 • List Price $ 1,099 US • Command premium pricing • Enterprise Class Performance • Medium Entry Product (price reduction) • AP 4121 • List Price $ 699 US • Standard product, lower Street Price • High Performance MAC Layer Bridging

  4. Application Application Presentation Presentation Session Session Transport Transport Network Network Link Link Physical 802.11(a), (b) Physical Ethernet AP 4121; Layer 2, with some L3 Function Client Server Bridging Function Link Link Physical 802.11(a), (b) Physical Ethernet Wireless RF Cable

  5. AP 4121 Price Performance Winner $ 200US 7 Price Performance Winner; Price against Cisco350; Performance against All Others

  7. AP 4131 Best in Class Product – Feb ‘02 $ 200US 10 In Feb We Were Beating Cisco on Price and Performance

  8. AP 4131 Best in Class Product – Mar ‘02 8 10 We Made Cisco Eat Margin! – We Still Lead on Performance

  9. Access Point Positioning Summary

  10. T3.5 is Winning in Verticals • 66B Food/Food Services Retailer • 500 APs (1.5M+ ): Loser Cisco 350 • 50B Food Retailer • 6 Years of pain to unseat: Loser Cisco 350 • One of the largest retailers in the World • 1st Store and DC Ever: Loser Cisco 350 Winning is Fun!

  11. Trilogy 3 Access Point Hardware High Gain Fixed DiPole Antenna Option

  12. Trilogy 3 Access Point Hardware • Includes all T2.5 Software Features • Faster Processor = Better Throughput • More Memory = More Features • AP Radio Card Integrated Inside AP • 10/100 Ethernet Port

  13. Cisco 3xx “Killer” Secure – Deployable - Reliable Competition “Killer” WLAN Services T3.5 Feature Differentiators: • RF Bandwidth Management • Voice, Data, Air QOS • 802.15 Co-existence • Improved System Performance • Larger BC/MC Queue, Embedded Web Server, MU Limits • 802.1x / EAP-TLS* • Windows XP Compatibility • Flexible Security* • WEP, Kerberos, EAP/TLS One, Two, All – You Decide! • Secure Wire Side Management* • SNMP v.3 • TKIP ** • Solves WEP Exploit * New Security Feature * Planned Feature

  14. Raw Throughput Comparison Purpose:To observe maximum throughput achieved during continuous 100KB file transfers to and from a wired computer to a MU. Environment: No RF Interference, some multipath, private wired network Results:The table below lists the average throughput of continuous (for 5 minutes) Gets (wired -> wireless) and Puts (wireless -> wired). The average of the Gets and Puts is taken as the effective throughput.

  15. Load Balancing Comparison Symbol T3 Cisco 350

  16. Roam Characteristics Comparison Symbol T3 Cisco 350

  17. Linux Kerberos Requirements • Trilogy 2.5 & 3.5 Requires Only Standard Components to Work • Microsoft Windows 2000 Advanced Server • Windows 2000 Active Directory* • DHCP Services* • NTP Services (Network Time)* • Symbol AP Configuration Text File SOLARIS™ • Free add-on to Microsoft Windows 2000 Advanced Server • Other O/S Have Similar Functionality

  18. Kerberos Provides High Performance Mobility Fast Roaming 55 milliseconds Consistent Roaming

  19. Mixed Security Modes

  20. Backup Kerberos Server Support

  21. Backup TLS/Radius Server Support

  22. Wireless QOS Enhanced Interference Avoidance Properties • WLAN systems are data centric supporting low data rate applications (e.g., scan-send-beep, etc.) • With multimedia applications (voice, video, audio) proliferating, proactively managing the scarce wireless bandwidth is critical • The Intelligent Access Point (IAP) includes: • Packet Engine (PE)- Classifies data streams based on media type. Current support provides voice, video and data classes • Quality of Service (QoS) Manager- Prioritizes and Optimally schedules classified data streams based on policies set by system administrators according to their organizations needs • The technology can be extended in the future to support additional security management (firewall protection, content filtering), and accounting/billing (for different services)

  23. Wireless QOS – Framework Mixed Traffic Delivery Determines Type Traffic Classifier priorities, scheduling QoS Manager Priority 1 Priority 2 Priority n…

  24. Adaptive Interference Processing • Adaptable Rate Switching Algorithm • Optimizes 802.11b Throughput in Bluetooth Environment. • Uses Statistical Analysis in the AP to Predict Bluetooth Traffic/Interference • Provides Dramatic Throughput Improvement I am Bluetooth! Hear Me SHOUT…

  25. S24/AP How It Works • Downstream 802.11 Traffic is Most Susceptible • Conventional rate scaling algorithms might scale back all the way to 1 Mbps and stay there (scaling back results in increased collisions) • Need for a mechanism that predicts when Bluetooth is around and “lock” the transmission rate at the best possible point FTP Bluetooth FTP MU

  26. SNMP v.3

  27. AP Web Interface Improvements • Loading Speed • Display/Configure New Features • Simplified “Easy Install” • New RF Statistical Screens • Channel Retry • Retry Histogram

  28. Web Based Easy Setup

  29. Pass-Key – Simplified WEP Key Entry

  30. Pass-Key – Simplified WEP Key Entry

  31. What’s Planned for T3.7 • VLAN Support • Enhanced Over-The-Air Security (TKIP) • Rogue AP Detection • 3rd Party VPN Solution • Management UI Changes for Kerberos • Revamped “Unified” Client Drivers and Tools

  32. Questions… …Thank You
