7. February 2007 Market Environment [3] -Price sensitive market -Increase demand for value-added services -Trend of wireless technologies shows a reducing weight -Trendline could be reversed by WiMAX Source: IDC

8. February 2007 Access Alternatives [1] Access technologies  FTTx  xDSL  3G  Cable  WiMAX  WiFi

9. February 2007 Backhaul Alternatives

10. February 2007 How to chose Our suggestion - Based on: -Lower initial costs -Resilience -Robustness -Flexibility -Scalability -Quality

11. February 2007 Meaning: WiMAX access, Wireline core and distribution

12. February 2007 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

13. February 2007 Hybrid model SWOT StrengthsWeaknesses  Easy to deploy  Low cost for deployment and operations  High speed and long range  Flexible solution  QoS  In case of large urban areas, where more than one cell is required, the number of wireline backhauls increase OpportunitiesThreats  Deployment of regional/national WiMAX  NA
