1. A radio apparatus comprising:
- a detector configured to detect movement of the radio apparatus between an inner area and an outer area, the inner area being inside a boundary including intersection and the outer area being outside the boundary; and
a communicating unit configured to perform one of a first communication process for the inner area to transmit a first packet signal, and a second communication process for the outer area to transmit a second packet signal, depending on whether the radio apparatus is within the inner or outer area, the first packet signal being more important than the second packet signal for collision prevention of vehicles, whereinwhen the detector detects that the radio apparatus moves from the inner area to the outer area, the detector outputs a signal to notify a user that the radio apparatus has moved to the outer area from the inner area.

Abstract
An extracting unit detects movement from a first area to a second area, the first area and the second area defined as areas having different priorities. When the extracting unit detects the movement, this changes a communication process defined in the first area to the communication process defined in the second area. A notifying unit notifies that the area changed when the movement is detected. Herein, the priority of the first area and the priority of the second area are defined according to importance of a signal, which should be broadcasted from a processing unit.
