7. Why the Need for Extricom?A New Era of Expectations for Enterprise WLAN • What Enterprises want from their WLAN Investment • Mobility - Voice demands mobility • Convergence – Means adding voice to data • Multiple Services on One Infrastructure • Lower cost of ownership – complexity must not grow with deployment scale • The Challenge • Need greater coverage and bandwidth, but these are mutually exclusive in traditional implementations • Require mobility, but 802.11 is not mobile • Convergence requires Quality of Service mechanisms not in 802.11 • Must control the cost and complexity of ownership as Wi-Fi network grows • Today’s technology approach is limiting • Cannot achieve the performance required by new demands • Too complicated, complex, and costly

8. The Extricom WLAN • Shift from cell-based WLAN to “channel blanket” topology • Significantly more flexible, easy-to-own, and robust WLAN • 802.11 compliant, with an innovative & unique architecture

9. The Channel Blanket Benefits • Simple • No RF Cell Planning • Plug-and-Play deployment • Does not require RF expertise • Flexible • Multi-layer WLAN, in One Infrastructure • Concurrent high-performance of all services, devices, and user types • Capable • Seamless mobility – which does not inherently exist in the standard • Maximized coverage and capacity – previously a trade-off • Enhanced bandwidth – TrueReuse™ • Guaranteed Service Levels

10. Architecture

11. The Realities of 802.11 • Scarcity of Radio Channels • Throughput varies with distance • Protocol designed for portability, not mobility • Mixed mode (b/g) backward compatibility degrades capacity • Voice and data contention degrades capacity and service quality These traits are inconsequential in small deployments. But have major implications for mid-to-large systems. The Extricom solution overcomes all of the above constraints.

12. The Cell-Based WLAN The Single-Cell Experience 802.11 Logic and Radio Electronics Integrated into Access Point (AP) • Simplicity • No Co-Channel Interference • Seamless Mobility • Security with Mobility But still … limited coverage and unpredictable bandwidth

13. The Trouble with Cells…802.11 is meant for a Single-Cell Environment • Forces a Single-AP protocol to function in a Multi-AP Environment • Results in trade-offs: a “tug-of-war” Trade-Offs Coverage vs. Capacity Capacity vs. Mobility Mobility vs. Security This architecture is impaired by the 802.11 Standard.

14. 802.11: Implemented in a Multi-AP Environment COMPLEX INFLEXIBLE GIVE-AND-TAKE PERFORMANCE Everyone competes for the same wireless resource • Need RF expertise • Ongoing “tweaking” • Device configuration burden • Always Co-channel interference • No guarantees on throughput • Coverage gaps • Portability, not mobility • Unreliable wireless connections • Security conflicts with mobility

15. The Extricom Interference-Free™ Architecture SIMPLE FLEXIBLE CAPABLE • Multi-Layer WLAN • Guarantee QoS by separating: • voice, data, video • 802.11b and .11g • private / public zones • No RF cell planning • Plug-and-play install • Zero-configuration AP • No co-channel interference • Guaranteed throughput • Zero-handoff mobility • Complete coverage • TrueReuse™ - up to 10X Bandwidth • Wire-like connection • Secure while mobile, even WPA
