    • A positioning support device holds available stored data which enables a determination of characteristics of radio signals transmitted by the positioning support device, wherein the characteristics of radio signals are expected to be observable at different locations. The positioning support device automatically and repeatedly transmits the stored data. Mobile devices may receive the data to estimate their position based on the data and based on measurements on radio signals received at their current location. The positioning support device may be caused by some other apparatus to store the data that is transmitted by the positioning support device. The data may be obtained based on characteristics of radio signals observed by at least one mobile device at each of a plurality of measurement locations.

    • An apparatus obtains a set of radio data comprising signal strength related values for radio signals transmitted by a transmitter with an association of each signal strength related value with a representation of a geographical location (201). The apparatus applies a frequency transform to the obtained set of radio data to obtain transform coefficients, each transform coefficient comprising a transform index and an associated transform value (202). The apparatus selects a subset of transform indices having more significant transform values than the remaining transform indices (203) and compresses the transform indices by encoding each transform index exploiting a probability of occurrence of an index value of a respective transform index (204). The same or another apparatus decodes the compressed transform indices again for use in position operations.

    • An apparatus obtains results of measurements, which are performed by a mobile device on signals of communication nodes. The measurement results for each of the communication nodes include a signal strength related value and an identification of the communication node. The apparatus obtains for one of the communication nodes a stored indication of a location and a stored signal strength related value and determines a difference between measured and stored signal strength related values. The apparatus estimates the position of the mobile device based on the results of measurements and on obtained stored radio model data. In the case that the determined difference for the at least one communication node falls short of a predetermined threshold, the apparatus determines a distance between estimated position and indicated location for the at least one communication node, as an indication of a health state of stored radio model data.
