Cope with new platform
Technologies in telecommunications is changing rapidly in context of multiplexing / access technique (FDMA, TDMA, CDMA, OFDMA etc), modulation scheme, channel coding, protocol etc.  Some examples of introduction of new technology used in Bangladesh during the last 30 years are:
qAnalog PSTN phone
qDigital PSTN phone
qAMPS cell phone
qWireless Local Loop (WLL)
qGSM cell phone
qCDMA cell phone
qGPRS technique
qADSL, WiMAX 
To take right decision for rolling out a new network platform, different software tools are used. One of the popular tool used in Europe is techno-economic solution. Techno-economic evaluations of new network technology is analyzed 
The steps of techno-economic solution of a new platform network are:
  • ØService definition ( The services to be provided must be defined and the market penetration of these services over the period of study is used as the input parameter of the tool)
  • ØService tariff predictions ( The services are associated with a part of the total tariff of the service provider)
  • ØRevenue Model ( using the information of market penetration and tariff of services under study, the tool calculates the revenues of each year for the service set)
ØThe architecture scenarios provide a shopping list of components of the network (equipment, cables, cabinets, ducting, installations etc)   

ØNetwork component cost data base including more than 300 network components which are collected from many European sources)
ØInvestment model ( combining architecture scenarios and cost data base the investment of a year is calculated)
ØOperation and maintenance mode ( the OA&M costs includes the cost of repair parts including civil work and operations and administration)
ØInvestment and OA&M costs together provides the life cycle cost for the selected architecture scenario.
ØFinally combining service revenues, investment cost, operating cost and general economic inputs (discount rate, tax rate etc.) cash flow, loss-profit, NPV (net present value) , IRR (internal rate of return), Payback period etc are calculated.
