The 
Link Performance tool calculates the link budget, fading margins and outage probabilities for radio links. The user interface also provides an easy way to alter key parameters and update all subsequent calculations to take the alterations into account.
Together with the Interference tool, the coverage calculations (such as clearance), the automatic frequency and polarisation assignment and the presentation facilities (e.g. terrain profile and Fresnel zone display), this provides comprehensive support when designing poin-to-point links and link networks.
