A wireless communication device having extremely simple constitution is used, and a low-cost and low power consumption wireless network system with high-quality signals is provided. The wireless network system comprises a plurality of wireless communication devices (101) each comprising a radiating oscillator (1) configured to integrate a transistor into a microwave oscillating resonator to generate a negative resistance and to commonly use a function of an antenna (11), an intermediate frequency signal generating section (4) and a receiving signal detecting section (7). In the wireless network system, the wireless communication devices are arranged to face at a position, at least one of the wireless communication devices has an intermediate frequency signal generating section having a frequency band signal generating function different from that of others, the receiving signal detection section having a function that can discriminate and receive a frequency band different from that of others, a signal transmitted from the one wireless communication device is transmitted to the other facing wireless communication device, and the other facing wireless communication device receives and extracts the signal by the receiving signal detecting section.
