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 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”

802.11: Implemented in a Multi-AP Environment
COMPLEX
• Need RF expertise
• Ongoing “tweaking”
• Device configuration
burden
© 2007
GIVE-AND-TAKE PERFORMANCE
• Always Co-channel interference
• No guarantees on throughput
• Coverage gaps
• Portability, not mobility
• Unreliable wireless connections
• Security conflicts with mobility
INFLEXIBLE
Everyone competes for
the same wireless
resource
