Zusammenfassung: | A wireless network system is provided. The wireless network system includes a wireless sensing module, a gateway and a server. The wireless sensing module includes a sensing unit, a radio frequency unit, and a control unit. The sensing unit fetches an environment signal. The radio frequency unit uses spread spectrum modulation technique to generate a spread-spectrum environment signal, and the radio frequency unit transmits the spread-spectrum environment signal according to a control signal. The control unit runs in sleep mode and working mode. When the control unit runs in sleep mode, the control unit switches to working mode according to a real-time value and a real-time period. When the control unit runs in working mode, the control unit generates the control signal. The gateway communications with the wireless sensing module, the gateway receives and demodulates the spread-spectrum environment signal to obtain the environment signal, and the gateway transmits the environment signal. The server receives t |
