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.

WiMAX-BWA 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)

WiMAX-BWA 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
