Title:
COMMUNICATION DEVICE, SYSTEM INCLUDING COMMUNICATION DEVICE AND PROGRAM
Document Type and Number:
Japanese Patent JP2017200114
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a communication device capable of easily determining transmission power bringing sufficient allowance.SOLUTION: The communication device includes: a communication part that communicates with an RF tag in a non-contact manner; and a control part that controls the communication part. When the communication part transmits a signal while changing the transmission power, the control part acquires signal strength and communication success rate from a signal received by the communication part (S7, S9), determines the transmission power after change corresponding to the signal strength exceeding a threshold level and the communication success rate in the acquired signal strength and the communication success rate in the electric power after the change of the transmission power (S13), and outputs a piece of information relevant to the determined transmission power (S15).SELECTED DRAWING: Figure 5
