“…The D * : argmaxER fg is detailed in (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12), It is important to indicate that all values are carried at net present value (NPV); CAPEX is loaded at the beginning of a year; income and OPEX at the end of a year and since there is no OPEX value for year zero, investment at both the beginning and the end of this year is high, giving negative cash flows in some cases:…”

“…Another point to highlight is how to find and analyze possible solutions that seek to minimize the costs involved by CAPEX and OPEX to maximize the benefits expected by telecommunications operators. Therefore, communication architectures that generate optimal topologies should be sought, in order to meet the requirements demanded by SG, SC and IoT and that at the same time save energy; possible alternatives from the scientific community point to the use of FiWi Hybrid Networks [4][5][6][7][8][9].…”

Nowadays, growth in demand for bandwidth, due to new and future applications being implemented, for services provided from smart grids (SG), smart cities (SC) and internet of things (IoT), it has drawn attention of scientific community, on issues related to planning, and optimization of communication infrastructure resources, in addition is necessary comply with requirements such as scalability, coverage, security, flexibility, availability, delay and security. Another important point is how to find and analyze possible solutions that seek to minimize the costs involved by capital expenditure (CAPEX) and operational expenditure (OPEX), but where it is possible to measure the uncertainty coming from stochastic projections, in order to obtain the maximum benefit expected to give access to users Who benefits from the services provided by SG, SC and IoT, on the other hand, we must look for communications architectures that generate optimum topologies to meet demanded requirements and at the same time save energy, possible alternatives highlight the use of hybrid networks of optical fiber links combined with wireless links (Fiber-Wireless, FiWi). This chapter seeks to provide planning alternatives to network segments linking universal data aggregation point (UDAP) with base stations (BS), this segment joins wide area network (WAN) with metropolitan area network (MAN).
