1. A method for evaluating channel information of a database, DB, said DB channel information being associated to a target area and being representative of expected characteristics of a wireless communication channel in said target area to be provided to one or more communication devices, wherein said method comprises:
obtaining, by a processing circuit, all or part of the DB channel information from the database;
obtaining, by the processing circuit, observed channel information representative of characteristics of the wireless communication channel experienced by a first communication device in the target area;
computing, by the processing circuit, a reliability indicator for the DB channel information for the target area, by comparing the DB channel information and the observed channel information and determining a timing information for said reliability indicator.
