GSM/GPRS/EDGE

Atoll includes state-of-the-art GSM/GPRS/EDGE features that provide comprehensive and accurate modelling of voice and data services, including full support of HCS and frequency hopping.

Multi-resolution predictions and optimised interference calculations facilitate planning as well as optimising mature networks that have a large number of sites and country-wide coverage.

Atoll also includes GSM/UMTS co-planning features that have been developed in partnership with leading wireless operators. Atoll 2.8 includes new GSM/UMTS interference analysis features that allow operators to analyse GSM and UMTS deployments in the same frequency bands.

Network Modelling

  • Support of dual-band networks
  • Support of HCS (Hierarchical Cell Structure)
  • Support for frequency hopping (baseband & synthesised), DTX and AMR
  • Modelling of GPRS and E-GPRS
  • Advanced service modelling

Service Planning and Analysis

  • Cell and network coverage analysis
  • GPRS/EGPRS/EGPRS2 prediction plots (throughput, coding scheme selection)
  • Interference analysis
  • QoS analysis: FER/BER/BLER/MOS prediction plots
  • Neighbour planning and handover analysis

Traffic Analysis

  • Multi-service traffic map generation from multiple sources: vector, raster and live traffic data
  • Traffic spreading between cell layers with trafficoverflow modelling
  • Cell dimensioning for mixed voice/data traffic and timeslot configurations
  • Traffic analysis including calculation of KPIs such as packet delay, blocking rate, etc.

Interference Matrix Generation

  • Prediction and drive test-based interference matrices
  • Support of subcell-based (e.g., BCCH, TCH) quality thresholds
  • Open format allowing editing and modifying interference matrices using 3rd party applications

GSM/UMTS Co-planning

  • Site sharing
  • Simultaneous display and analysis of GSM and UMTS networks
  • Inter-technology handover modelling based on proven intra/inter-technology neighbour allocation algorithms
  • Inter-technology interference analysis (e.g GSM 900 and UMTS 900)

Automatic Frequency Planning - AFP

  • Advanced algorithm based on a soft penalty approach
  • User-definable constraints and editable cost function
  • Allocation of frequency hopping parameters (HSN, MAIO, MAL)
  • Integration with 3rd party AFP tools through an open API

Automatic Cell Planning - ACP

  • Automatic optimisation of network parameters to increase coverage & capacity
  • Site selection and activation for greenfield and densification scenarios
  • Antenna selection & parameter optimisation (azimuth & tilt)
