Highly Compatibles with Legacy Network Devices 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. Layer 2.5 Layer 2.5 Mesh Network design benefits: � Highly Compatible with existing Routers, Switchs, Gateways, access servers � Fast packet switching design to minimize latency 6
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 28Mbps 14Mbps 7Mbps 3.4Mbps Theoritical Mesh Performance 32 28 24 20 16 12 8 CH 100 CH 100 CH 100 4 n 0 0 1 2 3 4 Mesh Type 1 [1/n] Mesh Type 2 [(1/2) ] 7
Multiple RFs Vs Single RF Mesh (2/2) Switching Wireless Architecture Switching wireless architecture (e.g. Arrowspan, Bellair, Strixsystems) � All adjacent Mesh nodes run in different frequency � Need multiple radios, 3 to 6 radios � Maintain maximum throughput across unlimited hop counts � Usually throughput is 5 to 10 times faster than shared switching � Complete scalability 28Mbps 28Mbps 28Mbps 28Mbps Theoritical Mesh Performance 32 28 24 20 16 12 CH 100 CH 104 CH 108 8 4 0 0 1 2 3 4 ArrowSpan 8

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 More Nodes will with higher Weight connect to a setting for T3 Manager with a higher Bandwidth score Score: Low with lower Weight setting for T1 11
Fault Tolerance & Redundancy Intelligent Mesh Routing Technology Score: 8 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 Score: 2 Bandwidth score Score: 8 When a High bandwidth Mesh Manager encounters a problem, the Nodes under the High bandwidth Mesh Manager will automatically re- Score: 2 route to the Low bandwidth Mesh Manager to maintain service.
