Highly Compatibles with Legacy Network Devices
Layer 2.5 Mesh Network design benefits:
Highly Compatible with existing Routers, Switchs, Gateways,
access servers
Fast packet switching design to minimize latency
Layer 2 switching, operates at the Data Link layer in the Open Systems Interconnection model. Layer 2 switching can deliver data at the Link Speeds, and highly compatible compare with the Layer 3 design because it’s not required to deeply examine individual data packets.

Multiple RFs Vs Single RF Mesh (1/2)
Shared Wireless Architecture
Shared wireless architecture (e.g. Tropos, Cisco, Firetide) All Mesh nodes run in the same frequency Easier technology to implement Interference among nodes reduce throughput and increase latency Theoretically, the best throughput is 1/n, n is node numbers Hop counts recommended to less than 3 Low scalability because of throughput drop with hop count

Bandwidth Score System
Intelligent Mesh Routing Technology Bandwidth score based on Hop Count, Signal Quality, and Mesh Manager Weight. This guideline affects the routing decision of each node on the mesh network to decide which Mesh Manager to associate with.
Score: High with higher Weight setting for T3 Score: Low with lower Weight setting for T1
More Nodes will connect to a Manager with a higher Bandwidth score
SLIDE 12
12
Fault Tolerance & Redundancy
Intelligent Mesh Routing Technology
In Normal usage, Nodes could be set to associate with the Mesh Manager with a High bandwidth by setting the Weight of the Mesh Manager to increase the Bandwidth score When a High bandwidth Mesh Manager encounters a problem, the Nodes under the High bandwidth Mesh Manager will automatically re- route to the Low bandwidth Mesh Manager to maintain service.
