MOBILE NETWORK DESIGN (MND)

MND

Customer requirements- Traffic forecast- Coverage objectives- Quality of Service objectives

Country data- Fixed network architecture- Frequency availability- Cartography data

- Number and configuration of BTS- Frequency requirement- Expected quality of service- BSS topology- NSS topology- Transmission network- Network evolution plan

Preliminary Network Design (PND)



RNP : Step 1

Customer answer to RNP questionaire- Traffic forecast- Coverage objectives maps- Available frequency bands- Quality of Service objectives- Fixed network architecture- Recommended cell sites- Scheduling requirements

Preliminary Network Survey

- BSS architecture : BSC, BTS, transmission- Configuration of BTS and antenna system- Identification of site search area - Preliminary frequency allocation- Predicted quality of service- BSS evolution plan

Initial Network Design (IND)

RADIO NETWORK PLANNING (RNP) - Step 1

Analog Field MeasurementsRadio Model Calibration

Terrain data base- Topography- Morphostructure- Building database

Preliminary Network Design



Initial Network Design

Analog Field MeasurementsSpecific Sites validation

Sites evaluation

- Radio site and BTS details - BSC and transmission details

- Initial frequency plan - Neighbouring cell relationship - Initial system parameters
