Predicting Performance of a Localization-Related Device

It is provided a method for enabling predicting performance of a localization-related device in relation to localization and/or mapping, the localization-related device forming part of a device network. The method is performed in a predictor device and comprises the steps of: detecting that a first localization-related device joins the device network; obtaining a first set of properties of the first localization-related device; determining, based on the first set of properties, a predictive model for the first localization-related device; and deploying the predictive model for the first localization-related device.
