3.3.4.2 Project identificationMAIN FEATURES TO BE CHECKED AND ANALYSEDSpecific data <strong>of</strong> the project:- A clear idea should be given <strong>of</strong> two aspects, which are strongly interrelated,- type(s) <strong>of</strong> telecom service <strong>of</strong>fered,- the implementation programme and the target market share.Technical and engineering features (for example):- physical data such as the length <strong>of</strong> cables (km) and area covered by the network (square km), the number and position <strong>of</strong>commutation/connection nodes,- data, building techniques and technical features <strong>of</strong> networks,- data, building techniques, technical features and layout <strong>of</strong> auxiliary plants e.g. electricity supply, lighting, and remote control,- covered area (square metres).Functional features (for example):- type <strong>of</strong> communications infrastructure, traffic volume and type,- maximum communication speed (baud),- the functional and physical links between the projected infrastructure and the existing telecommunications system,- type <strong>of</strong> commutation, communication pro<strong>to</strong>col, frequency bands (GHz) and power (kW).3.3.4.3 Feasibility and option analysisIn order <strong>to</strong> verify the feasibility <strong>of</strong> the project, the key issues are the volume <strong>of</strong> traffic and the daily, weeklyand seasonal trends (the optimum capacity must be a reasonable compromise between the highest peaklevels <strong>of</strong> traffic and that which the system can handle).The different options in these kinds <strong>of</strong> <strong>projects</strong> could be related <strong>to</strong>:- possible technical alternatives within the same infrastructure (e.g. different types <strong>of</strong> cables, differenttransmission pro<strong>to</strong>cols, different commutation/connection technologies etc.),- alternative locations for radio stations, possible global alternatives for the projected infrastructure,which can <strong>of</strong>fer similar services such as a satellite transmission or mixed network (air-cable) rather thanoptic fibre cables.3.3.4.4 Financial analysisThe financial inflows and outflows are:Financial inflowsFinancial outflows• Sales for services (tariff based) • Investment costs• Rent <strong>of</strong> equipments - works• Accession charges - general expenses- expenses for new equipment• Operating costs- raw materials for production- maintenance- technical and administrative personnel costs- fuel and electricityThe time horizon is usually 20 years for cabled networks and long distance cables but shorter (10 years)for other components.3.3.4.5 Economic analysisThe benefits <strong>of</strong> a telecom project are mainly <strong>to</strong> be found in the increasing efficiency and accessibility <strong>of</strong>the existing services and in the additional services provided.- the time saved for each communication (waiting time, transmission time, etc.), quantifiable byappropriate measurement units according <strong>to</strong> type <strong>of</strong> service; for valuation purposes the users may bedivided in<strong>to</strong> categories, for example in the household sec<strong>to</strong>r reference can be made <strong>to</strong> the averageBenefits income <strong>of</strong> users, and in the business sec<strong>to</strong>r <strong>to</strong> the average added value- the new additional services, that would be unavailable without the project. In some cases the timesaved method can be applied for their quantification and valuation, but in most cases it is possible <strong>to</strong>estimate the willingness-<strong>to</strong>-pay for the service by the usersCosts - local environmental impacts116
