Title:
WIRELESS COMMUNICATION TERMINAL, WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/196316
Kind Code:
A1
Abstract:
[Problem] To provide a wireless communication system capable of easily establishing a channel for communicating. [Solution] This wireless communication system (1) is provided with a parent device (10) and a child device (20). The parent device (10) and child device (20) are each provided with a GPS receiving unit and a wireless communication unit. The parent device (10) and child device (20) implement carrier sense synchronized with a high-precision GPS time obtained from a GPS signal. At that time, the parent device (10) and child device (20) belonging to the same group are configured in advance so as to implement carrier sense for the same initial channel. Further, the parent device (10) and child device (20) share a method of changing the channel in the case that the initial channel is not idle. By this means, the parent device (10) and child device (20) are synchronized with the GPS time to detect idle channels with the same timing to a high degree of accuracy, making it possible to establish communication between the parent device (10) and child device (20).
