Patent ID: 8160492

Claim:
A wireless network system which relays and transmits various signals to each other comprising: a plurality of wireless communication devices each including: a radiating oscillator having a configuration of a transistor integrated with a microwave resonator for oscillation, which generates a negative resistance, and commonly gives an antenna function of emitting an electromagnetic wave to a space; an intermediate frequency signal generating section which outputs an intermediate frequency signal to the radiating oscillator; and a receiving signal detecting section which receives a transmitted signal, wherein the wireless communication devices are arranged to face at a position where pull-in phenomenon are generated between each other, 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 the other wireless communication devices, the receiving signal detection section having a function that can discriminate and receive a frequency band different from that of the other wireless communication devices, and a signal transmitted from the one wireless communication device is transmitted to another facing wireless communication device which is synchronized with the signal transmitted by a pull-in phenomenon, and the other facing wireless communication device receives and extracts the signal by the receiving signal detecting section.
