Drive Test & Network Optimization

Drive Test is conducted for checking the coverage criteria of the cell site with the RF drive test tool. The data collected by drive test tool in form of Log files are analyzed to evaluate the various RF parameters of the network.

All the practical elements in this testing are carried out on a live network.
  • Call drop analysis
  • Handover
  • BCCH
  • Interference analysis : C/I, C/A
  • Link budgeting
  • Neighbour list scanning
  • Dedicated mode procedure
  • Speech Quality
  • GPRS testing
  • KPI analysis

Network Optimization Tools Used

  • TEMS
  • Genex probe
  • Genex Assistant
  • Agilent
  • Actix Analyzer
  • CNA
  • CNT

Optimization

Optimization is carried out in the network to minimize the call drops and RF interference in the network, to increase the indoor & outdoor coverage & better speech quality.

Steps taken:
  • Swapping analysis
  • Checking BSS parameters to meet RF objective
  • Adjusting orientation & tilt of the GSM antenna
  • Height adjustment of GSM antenna
  • Installation of TMA(tower mount amplifier)wherever required
  • Additional cell site if required
  • Indoor solutions for Indoor coverage
