A system which provides location based notifications comprising: - at least one mobile device whereby notifications specific for a subscriber can be transmitted to that subscriber and which serves the purpose of determining the location where the subscriber is present; - at least one receiver which is adapted to enable the ambient sound to be listened by the mobile device; - at least one detection unit; - at least one sound emission apparatus which has a certain ID information and is adapted to transmit this ID information owned by itself through the sound broadcasting that it performs; - at least one wide area location monitoring unit; - at least one database which is included within the wide area location monitoring unit and is adapted to keep the location information about the indoor areas where the sound emission apparatuses are installed; - at least one small area location monitoring unit; - at least one database which is included within the small area location monitoring unit and is adapted to keep the ID information and the location information of the sound emission apparatus and the information received by the small area location monitoring unit from the detection unit paired with subscriber data; - at least one notification platform which is adapted to receive the information recorded on the database by the small area location monitoring unit and is adapted to send notifications such as content, campaign, offer to the related subscriber for these records over the remote communication network and is adapted to receive answer of the subscriber over the remote communication network in cases where answer can be received from the subscriber by means of the mobile device and characterized by - the at least one detection unit which is adapted to operate on the mobile device and essentially is adapted to enable the sound received by means of the receiver to be examined and defined, can be powered on/off remotely; - at least one wide area location monitoring unit which can power on and power off the detection unit remotely according to status of match between the coverage area where the subscriber is present and the area where the sound emission apparatus is installed by determining the mobile device location through the device's use of the remote communication network; - at least one small area location monitoring unit which is adapted to track power on/off states of the detection unit, and is adapted to enable related components to reach these information by receiving and recording the information received from this unit. - at least one mobile device whereby notifications specific for a subscriber can be transmitted to that subscriber and which serves the purpose of determining the location where the subscriber is present;
