Atoll supports integrated network planning for 3GPP2 multi-RAT networks combining CDMA with 5G NR, 4G LTE, and 4G NB-IoT.

It features a multi-technology network database, a unified traffic model, a combined Monte Carlo simulator, and a multi-RAT ACP (Automatic Cell Planning) module. Atoll provides operators with a comprehensive and evolutionary framework for planning and optimising multi-technology networks including small cells, integrated Wi-Fi, and IoT.

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
