Title:
WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/186218
Kind Code:
A1
Abstract:
A wireless communication system comprises a base station (wireless base station (WBS)) and a plurality of terminals (sensor terminals (NN)) that wirelessly communicate with the base station. Each of the plurality of terminals has a state of transmitting a request for connection to the base station (connection request state (MADV)) and a reception state of detecting radio wave intensities (search state (MSCN)). Each of the plurality of terminals, when the other terminals each being in the state of transmitting the request for connection to the base station, transitions to the reception state of detecting radio wave intensities, and acquires the intensities of the radio waves transmitted by the other terminals.
