An electronic device includes a memory storing a first data set comprising a first plurality of files; a communicator comprising circuitry; and a processor configured to: identify an amount of files having a size less than a first threshold value among the first plurality of files; based on the identified amount of files and a communication state with a server, determine a size of a unit file to be transmitted to the server; convert the identified files having the size less than the first threshold value into the determined size unit, and generate metadata for the first data set while converting the identified files; and control the communicator to transmit the first data set including the converted files and the metadata for the first data set to the server.

Electronic device for transmitting data set to server and control method therefor

An operating method for a location estimation apparatus communicating with an access point (AP) in a wireless communication system according to an embodiment of the present invention comprises the steps of: receiving, from a second AP, a first received signal strength indicator (RSSI) signal having been measured at a first AP, and generating a first RSSI vector corresponding to the first RSSI signal; calculating a path loss exponent, using the distance between the first AP and the second AP and the first RSSI vector, and generating a second RSSI vector of each of multiple sub-areas divided from an entire area, using the path loss exponent; and generating a radio map of the entire area, using the first RSSI vector and the second RSSI vector.
