RF Planning and Design

Achieving maximum capacity while maintaining an acceptable GoS and good speech quality is the main aim of RF Planning.  We have expertise in ;

  • Radio network dimensioning
  • Coverage Planning
  • Capacity Planning
  • Frequency allocation
  • Interference analysis & recommendation
  • Coverage prediction plotting
  • Parameter planning

 

RF Optimisation

RF Optimization is one of the key challenges in any Cellular Network. Optimization is a continuous process and helps in understanding the shortcomings in mobile coverage and quality. Optimization helps to improve the spectral efficiency and provide better Quality of Services to the mobile customers:

We offer high level analysis of radio network parameters and provide round-the-clock cell performance monitoring.   KPI improvement is provided in a short period with Sopanam’s highly skilled professionals for each BSC / RNC /Cluster / Network

The methodology of radio network KPI optimization services includes:

  • Cluster/Route drive test report and recommendation for improvement
  • Radio network modification report
  • 24 hrs Network performance monitoring
  • BSC/RNC/ Cluster based analysis
  • Cell/BSC/ RNC based parameters, Cell configuration analysis and changes
  • Radio Network capacity utilization analysis and re-dimensioning
  • Daily/Weekly/monthly network KPI trend report (Call Drop Rate, CSSR, HO SR, IRAT-SR, EDGE/HSDPA throughput, etc.)
  • Parameter fine-tuning
  • Defining missing neighbour relations
  • Proposing new sites or sector additions with pre-post of coverage plots
  • Proposing antenna tilt & azimuth changes
  • Antennae height increase / reduction
  • Proposing antenna type changes
  • BTS Equipment/Filter change
  • Re–tuning of interfered frequencies
  • Weekly customer complain analysis & action plan for improvement

 

Installation & Commissioning

Telecom Equipment Installation and Commissioning is done to provide seamless Network coverage & quality to the mobile subscribers. These services are rendered on a timely and very cost effective manner.

BTS / NodeB Installation & Commissioning:
