© 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 is not mobile Convergence requires Quality of Service mechanisms not in 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

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

© 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

© The Realities of  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.

© The Cell-Based WLAN The Single-Cell Experience 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

© The Trouble with Cells… 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” This architecture is impaired by the Standard. Trade-Offs Coveragevs.Capacity Capacityvs.Mobility Mobilityvs.Security

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

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