An information processing system is disclosed. A device conducts a predetermined process by sensing a neighboring radio signal state. An information processing apparatus is connected to the device. In the information processing apparatus, multiple sets of neighboring definition information in which a neighboring signal state is defined, is stored in a storage part. Neighboring definition information depending on a location indicated by location information is specified from among the multiple sets of neighboring definition information based on the location information received from the device. The specified neighboring definition information is sent to the device. In the device, the predetermined process using the neighboring information received from the information processing apparatus is conducted. Sensing information indicating a process result acquired by the predetermined process is generated.

A position detection system is provided in which it is possible to inhibit deterioration in accuracy of detecting a position of a terminal after communication environment is changed even in a case where the communication environment is changed in the position detection system. In the position detection system, a first terminal measures radio wave intensity of radio waves from a plurality of wireless connection devices in the first terminal, and transmits a measurement result to a position detection server through each of the wireless connection devices. A second terminal is disposed in a prescribed position, measures the radio wave intensity of the radio waves from the plurality of wireless connection devices in the prescribed position, generates first reference data including information of the measured radio wave intensity, and transmits the first reference data to the position detection server through the wireless connection devices. The position detection server receives the measurement result and the first reference data, updates the first reference data, which is maintained in a memory in advance, with the received first reference data, and estimates a position of the first terminal based on the measurement result, the updated first reference data, and positional information of the second terminal.

A virtual barrier system for determining a position of a mobile device relative to a virtual barrier comprises: a plurality of transmitters configured to broadcast a unique identifier; a management platform for storing positional data for each transmitter; a mobile application for installation on a mobile device. The management platform is configured to communicate with the mobile application. The plurality of transmitters are arranged in pairs, one of each corresponding with a first or second zone. The pairs are positioned to define the virtual barrier between said first and second zones. The management platform is configured to: (a) map the barrier; (b) receive transmitted data from the mobile application when the mobile application detects the unique identifier, and (c) send an alert to the mobile application for display. The first zone and second zone comprise different statuses, and the status of the second zone is dependent upon a specific user.

A position detection system is provided which is capable of inhibiting an increase in system costs and improving accuracy of detecting a position of a terminal. In the position detection system, a first terminal measures radio waves from a wireless connection device or a second terminal, and transmits a measurement result to a position detection server through the wireless connection device. The position detection server estimates that the first terminal is located in a position of the second terminal which has transmitted the radio waves in a case where the measurement result includes information of the radio waves from the second terminal, and estimates the position of the first terminal based on information of radio wave intensity of the radio waves from the wireless connection device, which is included in the measurement result, reference data, and positional information of the second terminal in a case where the measurement result does not include the information of the radio waves from the second terminal.
