LTE

Atoll LTE module is the first LTE network planning tool available on the market. It is already being used on a number of projects worldwide.

This new module is the result of a strong R&D program in 4G technologies which Forsk is conducting with strategic partners including world-leading equipment vendors and operators.

Network and Radio Parameter Modelling

  • Support of various frequency bands, channel bandwidths, and sampling frequencies
  • Support of TDD and FDD duplexing methods
  • Support of LTE OFDMA (DL) and SC-FDMA (UL) parameters:
    • Frame structure, subframes, slots and cyclic prefixes
    • Resource blocks, subcarrier widths, reference signals
    • Control channel overheads:reference signals, PDCCH, PUCCH, P-SCH, S-SCH etc.
  • Support for multiple modulation types and coding schemes
  • MIMO modelling: transmit diversity, spatial multiplexing (SU-MIMO), uplink collaborative MIMO (MU-MIMO), AMS

Traffic Modelling

  • Modelling of voice and data services
  • Multi-service traffic demand maps generated from multiple sources: vector, raster, and live traffic data
  • Subscriber traffic modelling

Simulation and Analysis

  • LTE Monte-Carlo simulator including power control, advanced RRM and scheduling algorithms, support for MIMO
  • Generation of prediction plots, based on simulationresults or on user-defined cell load figures including:
    • Cell and network coverage analysis
    • Uplink and downlink interference analysis
    • Uplink and downlink bearer coverage predictions
