A method performed by an apparatus, said method comprising: - receiving one or more observation reports, wherein each of said observation reports is associated with a respective radio positioning support device (200, 200-1, 200-2) of a plurality of radio positioning support devices (200, 200-1, 200-2) of a radio positioning support system, wherein each radio positioning support device (200, 200-1, 200-2) of said plurality of radio positioning support devices (200, 200-1, 200-2) is installed at a fixed installation position and wherein each of said observation reports contains an indication for a number of radio positioning support devices (200, 200-1, 200-2) of said plurality of radio positioning support devices and/or for each radio positioning support device (200, 200-1, 200-2) of said plurality of radio positioning support devices (200, 200-1, 200-2) from which a radio positioning support signal is observable at the installation position of said respective radio positioning support device (200, 200-1, 200-2) with which said respective observation report is associated; - determining, based on said observation reports, whether a predetermined radio positioning support criterion is met by said radio positioning support system, wherein said predetermined radio positioning support criterion is met if it is determined that at any position within a coverage area of said radio positioning support system at least a predetermined number of different radio positioning support signals is observable; and - when it is determined that said predetermined radio positioning support criterion is not met by said radio positioning support system, at least partially reconfiguring and/or causing at least partially reconfiguring said radio positioning support system. - receiving one or more observation reports, wherein each of said observation reports is associated with a respective radio positioning support device (200, 200-1, 200-2) of a plurality of radio positioning support devices (200, 200-1, 200-2) of a radio positioning support system, wherein each radio positioning support device (200, 200-1, 200-2) of said plurality of radio positioning support devices (200, 200-1, 200-2) is installed at a fixed installation position and wherein each of said observation reports contains an indication for a number of radio positioning support devices (200, 200-1, 200-2) of said plurality of radio positioning support devices and/or for each radio positioning support device (200, 200-1, 200-2) of said plurality of radio positioning support devices (200, 200-1, 200-2) from which a radio positioning support signal is observable at the installation position of said respective radio positioning support device (200, 200-1, 200-2) with which said respective observation report is associated; - determining, based on said observation reports, whether a predetermined radio positioning support criterion is met by said radio positioning support system, wherein said predetermined radio positioning support criterion is met if it is determined that at any position within a coverage area of said radio positioning support system at least a predetermined number of different radio positioning support signals is observable; and - when it is determined that said predetermined radio positioning support criterion is not met by said radio positioning support system, at least partially reconfiguring and/or causing at least partially reconfiguring said radio positioning support system.
