The invention discloses an IP dynamically bound wireless network construction method and a corresponding network architecture. The wireless network construction method of the invention deploys wireless access equipment AP at each target room, deploys POE power supply switches at various target floors, and converges the power supply switches to aggregation switches, wherein each aggregation switch is respectively connected to a core switch, and the core switch is provided with a wireless controller AC board card; an IMC server and a DHCP server are set up at an isolation area and fixed IP which is bound with an MAC is distributed for internal staff. After the network architecture of the invention is constructed, staff within a coverage area can use a notebook, a tablet compute (PAD), a smartphone and other mobile terminals with a wireless access function to access the network through a wireless network, and through a unified wireless channel, one person has one number can be ensured and in-building roaming can be achieved.
