## Abstract

According to one embodiment, when a control unit is notified of information in at least one second signal received by one of first and second wireless communication units after the control unit provides the second wireless communication unit with a command to transmit a first signal containing first address information and before a waiting time elapses and when the at least one second signal contains second address information assigned to an authentication apparatus having received the first signal, then the control unit provides the first wireless communication unit with a command to transmit a third signal for a connection request with the second address information set in a destination address.

## Claims

### Claim 1

A system, comprising:
first wireless communication circuitry configured to communicate via a first wireless signal conforming to a wireless LAN standard; and
second wireless communication circuitry configured to transmit a second wireless signal conforming to a standard of near field communication and notifying a service set identifier (SSID) to a first electronic apparatus,
wherein the first wireless communication circuitry is further configured to:
receive an association request frame comprising the SSID in a frame body from the first electronic apparatus;
transmit an association response frame comprising a status code to the first electronic apparatus after reception of the association request frame; and
receive a data frame from the first electronic apparatus, if the status code of the association response frame indicates a success.

### Claim 2 (depends on 1)

The system of claim 1, wherein the second wireless communication circuitry is further configured to transmit information of a first address assigned to the first wireless communication circuitry to the first electronic apparatus in accordance with the standard of near field communication, and the first wireless communication circuitry is configured to receive the association request frame comprising the first address in a destination address field.

### Claim 3 (depends on 1)

The system of claim 1, further comprising:
a first antenna coupled to the first wireless communication circuitry; and
a second antenna coupled to the second wireless communication circuitry,
wherein the first wireless communication circuitry is configured to receive the association request frame via the first antenna, and the second wireless communication circuitry is configured to transmit the second wireless signal via the second antenna.
