## Abstract

A terminal (1050) includes a light receiver (151) that receives a light signal emitted by an apparatus (1000), the light signal including an identifier (SSID) of at least one base station (470); a receiver (153) that performs a reception process on the received light signal to output reception data; a data analyzer (155) that selects one base station based on the identifier of the at least one base station that is included in the reception data; and a radio device (453) that establishes a wireless connection with the selected base station (470) by using the identifier of the base station (470) and wirelessly communicates with the base station (470).

## Claims

### Claim 1

A transmission apparatus comprising:
a light signal generator which, in operation, generates a light signal including an identifier of at least one base station associated with a class among classes of services, wherein as a rank of the class increases, a maximum transmission speed of a wireless communication scheme supported by a selected base station associated with the class increases;
a transmitter which, in operation, transmits the generated light signal to a terminal apparatus, wherein
the generated light signal causes the terminal apparatus to display a list including at least one wireless communication scheme available to the terminal apparatus based on the identifier included in the light signal, and solicits an input from a user to select one wireless communication scheme from the list including the at least one wireless communication scheme,
in a case where the transmission apparatus is located in an area of a first class, the light signal includes a first identifier of a first base station associated with the first class and a second identifier of a second base station associated with a second class that is lower than the first class, and,
in a case where the transmission apparatus is located in an area of the second class, the light signal includes the second identifier of the second base station associated with the second class and does not include the first identifier of the first base station associated with the first class.

### Claim 2 (depends on 1)

The transmission apparatus according to claim 1, wherein
in the case where the transmission apparatus is located in the area of the first class, the light signal includes the first identifier of the first base station associated with the first class, the second identifier of the second base station associated with the second class, and a third identifier of a third base station associated with a third class that is lower than the second class;
in the case where the transmission apparatus is located in the area of the second class, the light signal includes the second identifier of the second base station associated with the second class and the third identifier of the third base station associated with the third class; and
in a case where the transmission apparatus is located in an area of the third class, the light signal includes the third identifier of the third base station associated with the third class.

### Claim 3 (depends on 1)

The transmission apparatus according to claim 1, wherein
as the rank of the class increases, a range of a network accessible to the terminal apparatus that received the light signal becomes larger.

### Claim 4

A transmission method of a transmission apparatus comprising:
generating a light signal including an identifier of at least one base station associated with a class among classes of services, wherein as a rank of the class increases, a maximum transmission speed of a wireless communication scheme supported by a selected base station associated with the class increases;
transmitting the generated light signal to a terminal apparatus, wherein
the generated light signal causes the terminal apparatus to display a list including at least one wireless communication scheme available to the terminal apparatus based on the identifier included in the light signal, and solicits an input from a user to select one wireless communication scheme from the list including the at least one wireless communication scheme,
in a case where the transmission apparatus is located in an area of a first class, the light signal includes a first identifier of a first base station associated with the first class and a second identifier of a second base station associated with a second class that is lower than the first class, and,
in a case where the transmission apparatus is located in an area of the second class, the light signal includes the second identifier of the second base station associated with the second class and does not include the first identifier of the first base station associated with the first class.

### Claim 5 (depends on 4)

The transmission method according to claim 4, wherein
in the case where the transmission apparatus is located in the area of the first class, the light signal includes the first identifier of the first base station associated with the first class, the second identifier of the second base station associated with the second class, and a third identifier of a third base station associated with a third class, the third class being lower than the second class;
in the case where the transmission apparatus is located in the area of the second class, the light signal includes the second identifier of the second base station associated with the second class and the third identifier of the third base station associated with the third class; and
in a case where the transmission apparatus is located in an area of the third class, the light signal includes the third identifier of the third base station associated with the third class.

### Claim 6 (depends on 4)

The transmission method according to claim 4, wherein
as the rank of the class increases, a range of a network accessible to the terminal apparatus that received the light signal becomes larger.
