CellTrace Suite

CelPlan Technologies offers its Indoor Design Services which include:

  • Wave Propagation and Radio Network Planning
  • Connectivity Simulator for Sensor and MESH Networks
  • Graphical Editing of Vector Building Databases
  • Graphical Editing of Tunnels and Stadiums
  • Graphical Editing of Antenna Patterns

Our indoor design services provide unmatched indoor predictions with superior RF ray tracing propagation models.

  • Main Features
    • 3D vector databases with planar objects
    • Use of extremely fast & accurate propagation models
    • Static, Monte-Carlo, and dynamic network simulations
    • Planning of coverage and capacity as well as network simulations
    • Analysis of the capacity (throughput, max. data rates, packet delays, QoS, etc.) of the different radio links and cells in the network based on the coverage analysis and the traffic assumptions
  • Our indoor design services support a wide variety of air interfaces:
    • Simulations also support MIMO technology, Distributed Antenna Systems (DAS), leaky feeder cables and several other transmission modes

CelPlan can model RF propagation inside of buildings, within tunnels and in campus environments for any wireless technology. We can model & analyze coverage of the network to mitigate interference and guarantee coverage & sufficient capacity.

The highly accurate empirical and ray-optical propagation models used for our analyses are ideally suited for WLAN networks and their frequency bands:

  • Coverage analysis based on received power;
  • Capacity and data throughput planning carried out based on user density definitions and interference analysis;
  • Maximum data rate maps showing where high volumes of traffic can be served;
  • AP based evaluation of requested traffic & interference used to illustrate the potential of improvements & optimization of the network;
  • Coverage in unwanted areas can also be identified and exposed.


Analyses and Deliverables:


  • Indoor Scenarios (incl. campus areas)  => Multiple prediction and planning heights possible
  • Vector Databases (Buildings)
  • Empirical (COST 231 MW, etc.) and Ray-Optical (Ray Tracing, Dominant Paths) Propagation Models
