Title:
WIRELESS NETWORK SYSTEM
Document Type and Number:
WIPO Patent Application WO/2007/114522
Kind Code:
A1
Abstract:
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 is provided with a plurality
of wireless communication devices (101). The wireless communication device
is provided with an emitting type oscillating device (1) wherein a transistor
is integrated with a resonator for super high frequency oscillation to generate
negative resistance and an antenna (11) is commonly used; an intermediate frequency
signal generating section (4); and a receiving signal detecting section (7).
The wireless communication devices are arranged to face at positions where
pull-in effects are generated each other. At least in one of the wireless communication
devices, the intermediate frequency signal generating section has a frequency
band signal generating function different from that of others, and the receiving
signal detecting section 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 facing wireless communication device, and the facing
wireless communication device receives and extracts the signal by the receiving
signal detecting section.
