Title:
WIRELESS COMMUNICATION DEVICE AND SYSTEM, AND RADIOGRAPHY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/125939
Kind Code:
A1
Abstract:
Provided is a wireless communication device and system and a radiography system which are capable of conducting stable wireless communication. This radiography system comprises a radiation delivery device, a radiation image detection device and a control device. The radiation image detection device has a first communication unit. The control device has a second communication unit. The first communication unit includes a first transmission unit which wirelessly transmits a first radio signal of a first frequency band, a first reception unit which receives a second radio signal of a second frequency band that is different from the first frequency band, and a first transmission reception control unit which controls the same. The second communication unit includes a second transmission unit which wirelessly transmits the second radio signal, a second reception unit which receives the first radio signal, and a second transmission reception control unit which controls the same. The first and second transmission reception control units conduct communication by alternately overlapping a portion of a first communication period in which the first radio signal is transmitted and received and a second communication period in which the second radio signal is transmitted and received.
