Why?

-Lower initial costs-There are no major CAPEX involved

-Resilience-Alternate path reservation available

-Robustness-Duct deployed/ Beneath soil

-Flexibility-Wide bandwidths range/Easy provisioning

-Scalability-Upgrades/downgrades

-Quality-Available QoS

Hybrid model SWOT

Strengths Weaknesses

Easy to deployLow cost for deployment and operationsHigh speed and long rangeFlexible solutionQoS

In case of large urban areas, where more than one cell is required, the number of wireline backhauls increase

Opportunities Threats

Deployment of regional/national WiMAX
