Wireless communication apparatus

Abstract

A vehicle-mounted apparatus (1), which is a wireless communication apparatus, comprises: a wireless communication unit (16) that can perform wireless communications using at least a band of 5 GHz; a current-location detection unit (11) that detects the current location of the vehicle-mounted apparatus; and a wireless communication area prediction unit (15) that, while the wireless communication unit (16) is communicating, determines, on the basis of interference data (13), which is information related to the coverage of radio waves transmitted from another system using the band of 5 GHz and transmitting / receiving radio waves at a standstill, geographic data (14) and the current location detected by the current-location detection unit (11), whether switching channels of the wireless communication unit (16) is necessary or not, and that, if that switching is necessary, further directly selects a switching destination channel or causes the wireless communication unit (16) to select the switching destination channel.

Description

technical field [0001] The present invention relates to a wireless communication device that is assumed to be used while moving. Background technique [0002] Examples of wireless communication devices used in automobiles include hands-free devices, music players, and the like that are wirelessly connected to mobile phones via Bluetooth (registered trademark). In particular, in-vehicle devices incorporating functions as hands-free devices and music players, such as car navigation devices and in-vehicle audio devices, are widespread (see Non-Patent Document 1). [0003] Furthermore, the in-vehicle device has a built-in wireless connection function based on a wireless LAN (Local Area Network, local area network), and wirelessly connects a device with a wireless LAN communication function brought into the car by the user to the in-vehicle device, and also performs communication between multiple devices in the car. Such demand for wireless communication is also increasing. Wir...

[0011] Therefore, in the case of real-time transmission of large-capacity data such as video data using a wireless communication system equipped with a wireless LAN in the 5GHz frequency band, since the communication channel is changed during the transmission of video data, the transmission of video data at the time of the change is cut off, causing Defects such as blurring of the image on the receiver side of the image, and image stoppage
