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.
