Atoll WiMAX/BWA module delivers a comprehensive set of features for the design and optimisation of WiMAX and other Broadband Wireless Access (BWA) networks.


It also provides comprehensive Wi-Fi network modelling with coverage and capacity planning as well as multi-technology traffic modelling and analysis.

Network Modelling

  • Support for TDD and FDD WiMAX and BWA networks
  • Support for multiple frequency bands
  • Support for fractional frequency reuse
  • Subcarrier configuration and frame structure modelling
  • Support for permutation zones and subchannel allocation modes
  • Smart antenna modelling: conventional and optimum beamforming antennas
  • MIMO modelling: transmit/receive diversity, SU-MIMO, MU-MIMO, adaptive MIMO switching (AMS)

Traffic Modelling

  • Modelling of voice and data services with different QoS classes
  • Modelling of user terminals, customer premises equipment and antennas, user profiles, and traffic environments
  • Multi-service raster and vector traffic demand maps from multiple sources including traffic data from live network measurements
  • Fixed subscriber traffic modelling

Simulation and Analysis

Andvanced WiMAX Monte Carlo simulator including power control, RRM and scheduling smart antenna and MIMO modelling, and backhaul capacity constraints

Generation of prediction plots, based on simulation results or on user-defined cell load figures including:

  • Cell and network coverage analysis
  • Downlink and uplink interference analysis
  • Downlink and uplink service areas
  • Effective service areas
  • Downlink and uplink throughputs
  • Downlink and uplink quality indicator analyses
  • Preamble index, segment, and permbase collisions

Neighbour Planning

  • Manual and automatic multi-carrier neighbour planning
  • Inter-carrier and intra-carrier neighbour planning

Interference Matrices

  • Prediction-based interference matrices
  • Open format allowing import of measurement-based interference matrices and editing interference matrices using 3rd party applications

Automatic Frequency Planning - AFP (option)

  • User-definable constraints and flexible cost function
  • Allocation of frequency channels and fractional frequency planning (FFP)
  • Automatic preamble index planning
  • Automatic downlink/uplink permbase planning

Automatic Cell Planning - ACP (option)

  • Automatic optimisation of network coverage and capacity
  • Site selection and activation for greenfield and densification scenarios
  • Advanced radio coverage, quality, and capacity objectives
  • Antenna selection and parameter optimisation (height, azimuth & tilt)

Automatic Site Positioning - ASP (option)

  • Automatic creation of new site locations according to surface-wise, traffic-oriented and population-based coverage objectives
  • Site deployment in multiple zones (urban, suburban, rural, etc.), along roads and railways
  • Intelligent implementation plan with the selection of the best sites to deploy
