Computer readable media can be any available media that can be accessed by a computer and includes both volatile and nonvolatile media, removable and non-removable media. In addition, the computer-readable medium may include both computer storage media and communication media. Computer storage media includes both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Communication media typically includes any information delivery media, including computer readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave, or other transport mechanism.

The method of providing a wireless communication-based object location service according to an embodiment of the present invention may include a method of providing a wireless communication based object position estimation service by an application installed in a terminal (which may include a platform or a program included in an operating system, And may be executed by an application (that is, a program) directly installed on a master terminal by a user via an application providing server such as an application store server, an application, or a web server associated with the service. In this regard, the above-described method for providing a wireless communication-based object location service according to an embodiment of the present invention is implemented as an application installed in a terminal or directly installed by a user (i.e., a program) And can be recorded on a readable recording medium.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.
