Radio communication apparatus

摘要

An in-vehicle apparatus that is a radio communication apparatus includes: a radio communication unit capable of performing radio communication using at least a 5-GHz band; a present-position detecting unit that detects a present position of the own apparatus; and a radio-communication-zone predicting unit that determines, when the radio communication unit is performing communication, whether switching of a channel of the radio communication unit is necessary on a basis of interference data, which is information concerning a coverage of a radio wave transmitted from another system that uses a 5-GHz band and transmits and receives a radio wave in a stationary state, map data, and the present position detected by the present-position detecting unit, and, when switching is necessary, further selects a switching destination channel or causes the radio communication unit to select the switching destination channel.

1. A radio communication apparatus comprising:
a radio communication unit capable of performing radio communication by using a 5-GHz band; an interference predicting unit that predicts interference with another system that uses a 5-GHz band on a basis of an own position and interference position data in which information concerning a position where interference with the another system occurs is stored; a channel changing unit that changes a used channel when the interference is predicted to occur or when interference with the another system is detected by the radio communication unit; and an interference-position-data updating unit that updates, when interference with the another system is detected by the radio communication unit, the interference position data on a basis of a result of the detection.
