Abstract: A communication apparatus includes an acquisition unit that acquires identification information from a first different communication apparatus, a determination unit that determines whether the acquired identification information is first identification information, a reception unit that receives, from the first different communication apparatus, a predetermined request to connect a second different communication apparatus to a wireless network generated by the communication apparatus, and a providing unit that, in a case where the identification information is the first identification information, provides the second different communication apparatus with a communication parameter for connecting to the wireless network in response to receipt of the predetermined request.

Abstract: In order to provide a technique capable of more preferable wireless communication connection, a wireless communication apparatus transmits a probe request signal containing a predetermined information element; receives, from another wireless communication apparatus, a response signal to the probe request signal; obtains, from the other wireless communication apparatus, characteristic information indicating a communication characteristic of a wireless LAN in the infrastructure mode to which the other wireless communication apparatus is connected; and selects, based on the characteristic information, communicating with the other wireless communication apparatus via the wireless LAN in the infrastructure mode or directly communicating with the other wireless communication apparatus without going through the wireless LAN in the infrastructure mode.

Abstract: An operating state of a communication unit of a communication apparatus is kept for a keep period in accordance with a transmission cycle of control information transmitted by another communication apparatus. The communication apparatus wirelessly communicates with the other communication apparatus in the operating state. If the keep period elapses, the communication unit is switched from the operating state to a hibernation state. The communication apparatus does not communicate with the other communication apparatus in the hibernation state.

Abstract: A vehicle location detector detects the vehicle state such as the location and speed from a GPS signal. Memory stores map data and traffic regulation data in advance. It is determined whether there is the possibility that a driver commits traffic violations based on the vehicle state information and traffic regulation data on the road where the vehicle is traveling. In case it is determined that there is the possibility that the driver commits traffic violations, a traffic violation warning is output via voice and displayed on a display. It is also determined whether the driver has committed traffic violations based on the vehicle state information and traffic regulation data. In case it is determined that the driver has committed traffic violations, the traffic violation details are recorded in traffic violation memory.
