The communication quality judging unit 116 judges whether or not the communication quality between the target terminal and the access point 300 using at least one of the amount of packets successfully received from the target terminal for a predetermined period of time and the amount of packets transmitted to the target terminal for a predetermined period of time And performs a function of determining the quality state.

For example, when the target terminal transmits a predetermined packet, the communication quality determination unit 116 determines the communication quality status (status) between the target terminal and the access point 300 using the packet amount that is successfully received from the target terminal for a preset time .

The communication quality determination unit 116 may determine a communication quality state between the target terminal and the access point 300 using at least one of a time at which the predetermined packet is successfully received from the target terminal and a time at which the packet is successfully transmitted to the target terminal It can be judged.

Since the communication speed can be known by using the packet amount and the packet transmission / reception time, the state of communication quality with respect to the target terminal can be known.

Here, the packet transmitted by the target terminal arrives at the access point 300 through the wireless section, and then arrives at the communication terminal 100 again through the wireless section. In this case, wireless communication between the access point 300 and the communication terminal 100 Assuming that the packet transmission rate in the interval is much faster than the packet transmission rate in the wireless section between the target terminal and the access point 300, 300 can be judged based on the communication quality.
