This remote notification system includes a home network 10, a wireless notification device 3 connected to the home network 10, and a mobile phone 5 that can be connected to the home network 10.

  The home network 10 is a wireless local area network (LAN) having one or more access points 11 and is connected to the Internet 20. In general, a wireless LAN is a communication network that forms a cover area R0 using one or two or more access points 11, and connects wireless nodes existing in the cover area R0. That is, the wireless node can form a wireless link from any position in the cover area R0 to any of the access points 11, and can communicate with other wireless nodes via the wireless LAN. .

  Here, an example in which a wireless LAN is installed in a house and the cover area R0 is the home network 10 that covers the entire house will be described. However, in the present invention, a part of the house is defined as the cover area R0. Alternatively, the present invention can be applied to a wireless LAN in which a facility such as a store, an office, or a school has a cover area R0.

  The wireless notification device 3 is a notification device that notifies the mobile communication terminal 5 that a predetermined event has occurred. When a predetermined event occurs, the radio notification device 3 generates notification information related to the event, and transmits an email including the notification information to the mail address of the mobile communication terminal 5. The wireless notification device 3 is a wireless node installed in the cover area R0 and connected to the home network 10, and the mail transmission is performed via the home network 10.

  The mobile communication terminal 5 is a cellular communication terminal that performs wireless communication with the cellular base station 23, and here, an electronic mail including notification information can be received from the wireless notification device 3.
