10. Market analysis
Estimating the potential market and revenues for the 4G services:
• Geographical areas to be served (dense urban, urban, suburban/exurban, and rural)
• Market segments to be addressed (residential, soho, small, middle and large enterprises/institutions)
• Service profiles to be offered
• Market segment penetration per year
• Impact of churn

11. Technical analysis
The 4G network infrastructure is structured on the basis of the capacity and coverage
requirements, to derive the required bill of quantities, taking into account:
• Technology characterization (operating frequency,
channelization, duplexing, sensitivity, data rate, etc.)
• Base stations/eNodes B and user terminals/equipments
to be deployed in the network
• Path loss model for the link budget analysis (Cost-231,
SUI, ECC-33, Log-Normal with/without Shadowing, Free
Space)
• Down and up link capacity demand per year
• Existing backbone infrastructures
• Wireless backhaul technology distribution
(SDH, PDH, Native Ethernet, Other

12. Economic and financial
All the economic keys & financial projections (TCO, P&L, Cash Flow, Balance Sheet) and
indicators (Gross Margin, EBITDA, EBIT, NPV, IRR, PBP, Shareholder Value, etc.) are
calculated to assess the feasibility of the 4G initiative, considering:
• CAPEX & OPEX (spectrum license, Internet connectivity, access, backhauling, core network,
personnel, marketing, SG&A, etc.)
• Depreciations
• Interest rate on borrowings
• Tax rate
• Discount rate
• Financing
• Equity
• Perpetual growth

13. Scenario and sensibility analysis
• The influence of parameter and boundary condition changes is analyzed to
identify the most critical factors for the success of the initiative. A fast and
iterative fine-tuning of the 4G business case, in real-time and total privacy can be
performed, viewing the results in an animated graphical format instantly from
the different Market, Technical, Economic & Financial perspectives.

14. Comprehensive report
• At the end of the analyses, a very detailed report is automatically compiled and
published in editable formats.
• The report contains a complete summary (with tables, diagrams and charts) of
input parameters and assumptions, the results of the market analysis, the
outcome of the technical modelling, and the economic and financial statements.
