Described is a method and system for radio frequency (RF) signature generation and position estimation using the RD signature. A method includes receiving, by a server, a RF signature associated with a user device present in a connected environment, updating, by the server, stored RF signatures based on RF signatures received from the user device, monitoring stations, and active radio emitting devices in the connected environment when a defined threshold for one or more stored RF signatures is exceeded, where each stored RF signature corresponds to a subdivision in the connected environment, and estimating, by the server, a location of the user device in the connected environment by comparing the RF signature of the user device with the stored RF signatures or updated stored RF signatures.
