DETECTION SYSTEM FOR FORGETTING TO TAKE ALONG MOBILE ROUTER, DETECTION METHOD FOR FORGETTING TO TAKE ALONG MOBILE ROUTER, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a detection system for forgetting to take along a mobile router, the system preventing erroneous detection due to an external factor of forgetting to take along a mobile router with a user when the user taking along a mobile apparatus moves under a wireless communication environment in which the user takes along both mobile apparatus and mobile router to which the mobile apparatus belongs, and thereby can detect forgetting to take along the mobile router more reliably.SOLUTION: In addition to a mobile apparatus that belongs to a mobile router 10A, a detection system for forgetting to take along a mobile router further includes a communication module which is, for example, a cradle that can connect with the mobile router 10A. The system includes, in a main control unit 100A of the mobile router 10A, an SNR detection unit 110a that regularly detects an SNR value of each of the received wireless signals every predetermined constant time interval regarding two pairs of a pair-A denoting wireless connection between the mobile router 10A and the mobile apparatus and a pair-B denoting wireless connection between the mobile router 10A and the communication module.SELECTED DRAWING: Figure 5
