LTE

In 2008, Atoll LTE was the first LTE network planning software available on the market. It has since then been used on a number of projects worldwide. Atoll is a comprehensive framework for operators who need to plan evolution towards LTE. It allows planning and analysing integrated GSM/UMTS/LTE and CDMA/LTE networks.
This 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
