COMMUNICATION EQUIPMENT, COMMUNICATION QUALITY ESTIMATING METHOD, AND PROGRAM FOR COMMUNICATION QUALITY ESTIMATION

摘要

PROBLEM TO BE SOLVED: To easily find an installation position suitable for a relay.SOLUTION: A slave unit 2 capable of wirelessly communicating directly or via a relay 3 with a master unit 1 which transmits a radio wave includes: a radio wave intensity acquisition part 241 for acquiring first radio wave intensity as the intensity of a radio wave received from a master unit 1 at a first position and second radio wave intensity as the intensity of a radio wave received from the relay 3 installed at a second position farther from the master unit 1 than the first position at the first position; an estimation part 243 for estimating a communication quality level in the case of wirelessly communicating via the relay 3 installed at the first position with the master unit 1 at the second position on the basis of the acquired first radio wave intensity and second radio wave intensity; and a display control part 244 for allowing a display part 22 to display information based on the estimated communication quality level.SELECTED DRAWING: Figure 3
