A communication apparatus mounted on a vehicle includes: a first communication circuit that operates as an access point of an infrastructure mode and transmits and receives a radio wave toward and from a front side of the vehicle; and a second communication circuit that operates as a station of an infrastructure mode and transmits and receives a radio wave toward and from the front side of the vehicle.

Communication apparatus and communication method

The present invention improves the success rate of wireless connection in communications between moving objects or roadside unit-to-moving object communications. A wireless communication device () includes a first radio () and a second radio (). The first radio () scans, at one of the front and rear of a moving object (), a first connection destination detecting signal for first moving object-to-moving object communication or first roadside unit-to-moving object communication. The second radio () transmits, toward the other of the front and rear of the moving object (), a second connection destination detecting signal for second moving object-to-moving object communication or second roadside unit-to-moving object communication.

Wireless communication device, roadside unit, and wireless communication method

An in-vehicle apparatus to be mounted in a vehicle includes receiving circuitry, which, in operation, receives, from a roadside apparatus providing a distribution service of a road video, an advertisement message indicating that the distribution service is provided; control circuitry, which, in operation, generates, based on reception of the advertisement message, a message regarding transmission of the road video to the roadside apparatus; and transmitting circuitry, which, in operation, transmits the message to the roadside apparatus.

In-vehicle apparatus, roadside apparatus, and communication method

A communication apparatus mounted on a vehicle includes: a camera that captures a still image used for generating a map; a positioning circuit that positions a captured position of the still image; a control circuit that associates position information indicating the captured position with image data of the still image; and a communication circuit that establishes a radio communication with a roadside unit and transmits the image data by radio to the roadside unit, in which the control circuit rearranges an transmission order of the image data to be transmitted by radio to the roadside unit, based on the position information.

Communication device and communication method

This wireless communication terminal device includes a control circuit that: causes, after receiving a beacon from a base station device, a connection to be established between the wireless communication terminal device and the base station device using a first control program; if a connection notification request to an external server was received from one or more application programs, uses a second control program, after the establishment of the connection, to output a connection establishment notification to the one or more application programs; and after the connection establishment notification is received, outputs to a communication circuit, via the first control program, a communication request to the external server device by the one or more application programs. The communication circuit of the wireless communication terminal device transmits the communication request to the base station device.

Wireless communication terminal device, and wireless communication method therefor

A wireless communication device for a road side zone includes a wireless communication circuit that forms beams in plural different directions in a time division scheme in an area which includes plural routes. The wireless communication device for a road side zone includes a recording circuit that records time transition in the direction of the beam used by the wireless communication circuit, which forms the beams in the plural different directions in a time division scheme, for wireless communication with a second wireless communication device provided to a mobile apparatus which moves on any of the plural routes.
