Document Type and Number:
Japanese Patent JP2016025428
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a communication system, a communication device, a communication method and a communication program capable of reducing an interruption of communication between devices.SOLUTION: The communication system comprises a first device and a second device transmitting and receiving a signal using a radio wave. The first device includes: a detection unit which detects a radio field intensity of a signal received from the second device; a determination unit which determines whether or not the radio field intensity is lower than a first threshold; and a control unit which transmits an instruction to increase when the determination unit determines to be lower. The second device, on receiving the instruction to increase, increases the output intensity of the radio wave.SELECTED DRAWING: Figure 4
