Abstract
Disclosed are a wireless network area limiting method and a wireless network area limiting system based on NFC. The wireless network area limiting method includes a step of adopting a plurality of first NFC hot spot sensors to seamlessly define a limited area having any shape; a step of periodically generating and transmitting an area secret key by a first central control part respectively connected to the plurality of first NFC hot spot sensors; and a step of conducting handshake with the first central control part by a WLAN user equipment, which has a NFC function and is located in the limited area, based on the area secret key received by the WLAN user equipment, so that the first central control part establishes area-limited network communications in the limited area.
