Patent ID: 8472880

Claim:
A wireless communication system, comprising: a first unit configured for wireless communication via a radio wave with a base station, configured for communication with a public network through the base station; and a second unit configured for wireless communication via a radio wave with the first unit, wherein: the second unit is configured for communication with a public network through the base station via the first unit, and wherein: the first unit includes: a measuring unit which measures a reception electric field strength of the radio wave in the first unit transmitted from the base station to the first unit; and a transmitter which transmits information of the reception electric field strength measured by the measuring unit to the second unit; and the second unit includes: a receiver which receives the information of the reception electric field strength, transmitted by the transmitter of the first unit; a first indicator which indicates at the second unit the information of the reception, electric field strength received by the receiver of the second unit; a second measuring unit which measures a reception electric field strength of the radio wave in the second unit transmitted from the first unit to the second unit; and a second indicator which indicates at the second unit information of the electric field strength measured by the measuring unit of the second unit.
