Atoll and its Live module combine prediction-based and measurement-based planning and optimisation techniques into a unique hybrid solution.


Atoll allows incorporating KPIs and UE/cell/MDT traces, and CEM data in order to add real-world information to predictions in a number of planning and optimisation tasks, hence extending both accuracy and scope of use.

The Live module includes UE/cell trace geolocation capabilities based on an intelligent combination of cell ID, timing advance, OTDOA, and RF pattern matching methods.

KPIs

  • Support for multi-technology KPIs
  • Import and management of KPIs from various sources (flat files and database connections)
  • KPI editor allowing user-definable thresholds and combinations
  • KPI display on map as transmitter or cell coverage/service area attribute

UE/Cell/MDT Traces and CEM Data

  • Support for multi-technology UE/cell/MDT traces and CEM data
  • Live connections to multiple UE/cell/MDT trace and CEM data sources (flat files and database connections)• UE/cell trace geolocation
  • Location and measurement display on map

OSS Interfaces

  • Multi-vendor UE/cell trace data import
  • Multi-vendor CM data interface
  • Multi-vendor GSM OSS interference and traffic data import

Radio Propagation and Coverage Plots

  • Combination of predicted path losses with path losses extracted from UE/cell trace measurements
