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

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
