Claim:
1. A system comprising: an apparatus; a first access point configured to transmit a first signal to the apparatus; a second access point configured to transmit a second signal to the apparatus; and a server device, wherein the apparatus is configured to: receive the first signal and the second signal, measure a first signal strength of the first signal and a second strength of the second signal, detect a first frequency of the first signal and a second frequency of the second signal, and notify the server device of the first signal strength, the second strength, the first frequency and the second frequency, and the server device is configured to: determine whether the measured first signal strength is greater that a first threshold value, determine whether a difference between the first frequency and the second frequency is less than a second threshold value, determine whether the measured second signal strength is greater than a third threshold value, when it is determined that the measured first signal strength is greater than the first threshold value, that the difference between the first frequency and the second frequency is less than the second threshold value, and that the measured second signal strength is greater than the third threshold value, determine that the first access point controls a transmitting timing of the first signal so as not to overlap a transmitting timing of the second signal, when it is determined that the first access point controls the transmitting timing of the first signal so as not to overlap the transmitting timing of the second signal, determine a signal quality of the first signal on the basis of the first signal strength while not using the second signal strength, when it is determined that the first access point does not control the transmitting timing of the first signal so as not to overlap the transmitting timing of the second signal, determine the signal quality of the first signal using both the first signal strength and the second signal strength, and transmit, to the apparatus, a command indicating an access destination based on the determined signal quality.
