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

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
© 2007 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

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.

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

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”
This architecture is impaired by the 802.11 Standard.
Trade-Offs
Coverage vs. Capacity
Capacity vs. Mobility
Mobility vs. Security

802.11: 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
