Abstract
A non-transitory computer-readable storage medium may store computer-readable instructions for a communication apparatus, wherein the computer-readable instructions, when executed by a processor of the communication apparatus, cause the communication apparatus to perform: obtaining first and second radio field intensities from the first external apparatus; calculating a first value indicating a ratio of the first and the second radio field intensities; obtaining third and fourth radio field intensities from the second external apparatus after receiving the third predetermined signal; calculating a second value indicating a ratio of the third and fourth radio field intensities; specifying a relationship between first and second distances by using the first and second values, the first distance being a distance between the communication apparatus and the first external apparatus, and the second distance being a distance between the communication apparatus and the second external apparatus; and outputting target data by using the specified relationship.
