Summary of Tool Utilisation

General dimensioning to calculate site requirements based uponcoverage, capacity, services etc

Produce initial estimates for network hardware costs

Quantify the impact of various UMTS options (TMA, STTD, 6-sector)

Estimate cell ranges for initial site acquisition searches

Business Case modelling for UMTS scenarios

produce cell ranges as input for more detailed simulation tool

Dimension3G Calculations

Optimisation of cell loading point for Coverage and Throughput

Higher Load Decreasing Range and Increasing Throughput

At Optimum loading point coverage and capacity goals met simultaneously

produce separate results for Uplink and Downlink

Optimise final results based on UL and DL combined


13/24




OVSF Code resource calculation

1 DL OVSF code per connected user in the cell

fixed Spreading Factor for each data rate, e.g. voice = 128; 384k = 8

higher rates / lower SF use more code resource

dimensioning results may be code limited


14/24




BTS Power estimates

DL power per user calculated from link budget

Power summed for all users in the cell

dimensioning results may be BTS power limited

at high load, Downlink Power limits cell range
