WiMAX/BWA

Atoll 3.1

Atoll WiMAX/BWA module delivers a comprehensive set of features for the design and optimisation of WiMAX and other types of Broadband Wireless Access (BWA) networks. It now provides comprehensive Wi-Fi network modelling with coverage and capacity planning as well as multi-technology traffic modelling and analysis (e.g. 3G<->Wi-Fi, LTE<->Wi-Fi).

Network and Radio Parameter Modelling

  • Support for TDD and FDD PMP networks
  • Support for multiple frequency bands
  • Subcarrier configuration and frame structure modelling
  • Support for different permutation zones and subchannel allocation modes
  • Smart antenna modelling: conventional and optimum beamforming antennas
  • MIMO modelling: transmit diversity, spatial multi-plexing (SU-MIMO), uplink collaborative MIMO (MU-MIMO), adaptive MIMO switching (AMS)
  • Support for repeaters and remote antennas
  • Site database can be shared with Atoll Microwave for backhaul planning

Traffic Modelling

  • Modelling of voice and data services
  • Support for all WiMAX QoS classes (UGS, rtPS, ErtPS, nrtPS, and BE)
  • Modelling of customer premises equipment and user profiles
  • Multi-service traffic demand maps generated from multiple sources: vector, raster, and live traffic data
  • Fixed subscriber traffic modelling

Subscriber Modelling

  • Fixed subscribers database
  • Subscriber display on map
  • Automatic & manual connection of subscribers to serving cells
