RESUMO:

THIS THESIS FOCUSES ON THE TECHNO ECONOMICAL EVALUTION OF TRANSPORT SOLUTIONS FOR FIXED AND MOBILE BROADBAND ACCESS. FOR FUTURE FIXED BROADBAND WE PROPOSE PROTECTION DEPLOYMENTS BASED ON FIBER-WIRELESS SCHEMES, WHILE FOR FUTURE MOBILE ACCESS NETWORKS WE PROPOSE BACKHAUL ARCHITECTURES USING FIBER AND MICROWAVE BASED ON GREEN WIRELESS ACCESS NETWORKS DEPLOYMENT AND COPPER-LEGACY BACKHAUL INFRASTRUCTURE BASED ON BROWNFIELD MIGRATION, I.E., USING LEGACY INFRASTRUCTURE UP TO ITS CAPACITY EXHAUSTION.

THE MAIN CONTRIBUTIONS GIVEN BY THIS THESIS ARE RELATED TO THE RESEARCH FIELD OF TOTAL COST OF INVESTMENT ON BROADBAND TRANSPORT INFRASTRUCTURE. IN TERMS OF TOTAL COST OF INVESTMENT WE PROPOSE TWO SET OF MODELS TO ASSESS THE CAPITAL AND OPERATIONAL EXPENDITURES, RESPECTIVELY CAPEX AND OPEX, OF FIXED DIFFERENT PROTECTED FIXED BROADBAND ARCHITECTURES AND WE COMPARE THE RESULTS WITH AN ARCHTECTURE BASED ON PASSIVE OPTICAL NETWORK HAVING NO PROTECTION SCHEME. IN THIS RESEARCH WE REVEAL THE ECONOMICAL BENEFITS OF USE HYBRID PROTECTION SCHEME BASED ON FIBER-WIRELESS ARCHITECTURE COMPARED WITH ALL-FIBER BASED PROTECTION OPTIONS AND FURTHER WE PRESENTED A SENSITIVITY ANALYSIS IN ORDER TO PROVE THAT THE EXTRA CAPEX INVESTED TO PROTECT THE INFRASTRUCTURE MIGHT BE RECOVERED OVER THE YEARS THROUGH THE OPEX. FINALLY, FOR MOBILE BROADBAND WE PROPOSE A SET OF MODELS CONDENSED IN A GENERAL METHODOLOGY THAT AIMS AT PROVIDE: TRAFFIC FORECAST, WIRELESS DEPLOYMENT, MOBILE BACKHAUL DEPLOYMENT AND TOATL COST ASSESSMENT. WE SHOW THAT, FIBER-BASED BACKHAUL CONSIDERING GREEN WIRELESS ACCESS IS THE MOST ENERGY EFFICIENT OPTION. FURTHERMORE, BROWNFIELD REVEALS THAT COPPER-BASED BACKHAUL CAN STILL PLAY A BIG ROLE IF USED UP TO ITS CAPACITY EXHAUSTION AND DRAMATICALLS REDUCES THE INVESTMENT COSTS IN INFRASTRUCTURE. ADDITIONALLY, WE PRESENT THE MAIN DIFFERENCES OF COST AND ENERGY VALUES BETWEEN GREEN WIRELESS ACCESS NETWORKS AND BROWNFIELD.
