  • 1. IK2514 Wireless Infrastructure Deployment & EconomicsHomework 3Dimensioning and Cost Structure Analysisof Wide Area Data Service Network Laili Aidi (aidi@kth.se) Communication Systems, School of ICT, KTH
  • 2. Scenario  Coverage type“Urban”: Population density 2000 / km2, total area 10,000 km2.  Usage type“MBB Substitute”, starting from 5 GB/Month in year 0, increasingprediction 1 GB/Month each year.  User penetration“Substitute_1”: starting from 1 % of total population in year 0, increasingprediction 1% each year.  Operator type“Greenfield”: has to deploy the network from scratch.  RAT options•  UMTS Macro•  HSDPA Macro•  HSDPA Micro
  • 3. Cost Dimensioning  UMTS Macro & HSDPA Macro
  • 4. Cost Dimensioning (cont.)  HSDPA Micro
  • 5. Money ?
  • 6. Approach1.  Coverage (km2) & User demandExample Year 0:•  20% coverage area means: 20 % x 10,000 km2 = 0 km2 total required coverage•  1 % user penetration means: 1 % x (2,000 x 10,000) = 200,000 total predicted user Total Predicted User Total Required Coverage (km2) 140000012000 1200000 10000 120000010000 1000000 1000000 8000 8000 800000 800000 6000 6000 600000 600000 4000 400000 4000 400000 2000 200000 2000 200000 0 0 0 1 2 3 4 5 6 1 2 3 4 5 6
  • 7. Approach2. Capacity demand (Mbps)Example Year 1:  Usage per User 6 GB/month/user, thus the user demand (UD1) is: 6 GB/month/user x 1,024 = 6144 MB/month/userAs traffic is concentrated in 4 hours / day, thus the user demand in Mbps (UD2) is: (UD1)/(30 days x 4 hours x 60 minutes x 60 seconds) x 8 = 0.113777778 Mbps/user  Then the capacity demand for the system would be: (UD2) x 400000 users = 45511.1 Mbps Total Capacity Demand (Mbps) 250000 227555.6 200000 170666.7 150000 121362.9 100000 79644.4 45511.1 50000 18962.9 0 1 2 3 4 5 6
  • 8. Approach3. Total equipment demand for each RAT option   Coverage achieved (CvTot) Coverage achieved by BTS deployment, would be: Cv = Maximum cell range * Amount of BTS Thus, total Coverage achieved on that year (CvTot) would be: CvTot = Cv + CvTot last years   Capacity achieved (CpTot) Capacity achieved by BTS deployment (Cp1) would be: Cp1 = Maximum capacity * Amount BTS Capacity achieved by add cell deployment (Cp2) would be: Cp2 = Maximum capacity * Cell Where Add.Cell (Cell) is: Cell = Amount of (Cp) BTS * (6-1) Thus, total Capacity achieved on that year (CpTot) would be: CpTot = Cp1 + Cp2 + CpTot last years
  • 9. Approach Data Line (DL) DL = (Cp1 + Cp2) / Data line capacity Site installation (SI) and Site build out (SB) SI or SB = Amount of BTS purchased Site Lease (SL) and Electricity (EL) SL or EL = Amount of BTS purchased + Amount of BTS purchased last year Leased Line (LL) LL = CpTot / Leased line capacity
  • 10. Result - UMTS Macro  BTS & Add Cell Demand  Installation - Built Out and Running Demand
  • 11. Result - HSDPA Macro  BTS & Add Cell Demand Installation - Built Out and Running Demand
  • 12. Result - HSDPA Micro  BTS Demand Installation - Built Out and Running Demand
  • 13. Comparison
  • 14. Comparison (cont.)
  • 15. Approach4. CAPEX, OPEX, and Total Cost CAPEX = (RTE Cost) + (Installation & Build out Cost) OPEX = Running Cost + (10 % x CAPEX) Total Cost = CAPEX + OPEX
  • 16. Approach5. NPV for each RAT option: Financial Viability PV = CF / (1 + r)^n NPV = PV0 + PV1 + .. + PV5
  • 17. Conclusion & Recommendation  UMTS Macro:-  High Add. Cell needs-  High RTE cost,-  High Installation & Build out cost-  Sharp increasing of OPEX  HSDPA Micro:-  Highest BTS deployment needs-  High Installation & Build out cost-  Sharp increasing of OPEX-  Highest capacity achieved  HSDPA Macro:-  Less BTS deployment needs-  Less CAPEX,-  Slow increasing of OPEX-  Best NPV Go for HSDPA Macro !
