Spectrum Engineering


Spectrum engineering has a defined lifecycle. The processes enable radio engineers to understand whether spectrum can be used in given bandwidth without causing undue interference to others.  This is often referred to as spectrum engineering or spectrum modelling. Spectrum modelling establishes the parameters to be applied to a spectrum band to ensure it does what is expected. Spectrum engineering is the process of making the spectrum do what it needs to do.

Spectrum engineering makes limited spectrum resources produce the maximum returns. It reduces the likelihood of interference and allows engineers to mitigate the risks associated with interference. It supports initiatives like frequency sharing and spectrum re-farming. Spectrum engineering removes risks by allowing regulators and network operators to model real-life scenarios to identify potential problems before network rollout.

Spectrum engineering can involve working with users in adjacent spectrum blocks to understand if the use of the licenses will impact others. Similarly, many equipment suppliers assess the compatibility of a frequency band to see whether it is fit for its purpose. Spectrum engineering removes the risks associated with a proposed network configuration and ensures the allocated spectrum will achieve the network operators objectives.


With over three decades of experience, ATDI is a leading spectrum engineering organisation. Some of the types of analysis available in HTZ, are listed below.

  • Migration analysis from analogue to digital communications;
  • Outdoor to indoor coverage by signal penetration loss calculation;
  • Population analysis from points, areas by vector polygon import or raster files
  • Propagation model tuning by correlation analysis between predictions and measurements
  • Traffic analysis by the ground occupancy, target areas or mesh blocks to cover


ATDI offer a variety of spectrum engineering service via their consulting services. These services span the whole network lifecycle from radio network planning, implementation to optimisation. Companies of every size from spectrum regulators, mobile network operators to emergency services, all rely on our know-how to get their work done.

A day in the life of our spectrum engineers is varied. Projects differ from analysing the impact of proposed radio services on adjacent channels to managing international coordination. Using our technical analysis tool HTZ Communications, allows engineers to model complex scenarios with ease. With decades of experience, our success is the direct result of staying ahead of the game, guaranteeing accuracy and exceeding customer needs.
