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

© 2007 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”

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
