Consecutive Point NetworksConsecutive Point Networks Scaleable & Flexible: Build to customer demand, matching

revenue generation with network investment outlay

Reliable & Available: Dual route (path) diverse links to customers

Backhaul to backbone network inherent in architecture (minimizes backhaul issue and cost)

Simpler RF planning: Easier adaptation as network grows in size and density (grow and evolve to mesh)

High spectrum efficiency: One 50 MHz channel pair gives greatest, most flexible, and highest bandwidth density per customer

Dense network deployment because of efficient RF spectrum management of co-channel interference

Uses state-of-the-art standard network equipment--fully future proof

--Best choice for medium to high capacity BW needs

Consecutive Point and Mesh TopologyConsecutive Point and Mesh Topology Mesh network advantages:

High survivability

Support heterogeneous and dynamic traffic patterns

Consecutive Point is a minimal form of mesh (n[the # of conections per node] = 2), which provides full redundancy

Consecutive Point can readily be expanded to complex mesh, if needed:

Economic justification of extra links:

• Additional capacity?

• Additional reliability?

--Typically ROI diminishes rapidly as n increases beyond two
