Abstract: A modulating and demodulating section receives, from another radio device, a packet signal including at least position information of another vehicle in which the other radio device is mounted. A position information acquiring section acquires position information of the vehicle in which the radio device is mounted. An estimating section estimates a time taken for the vehicle and the other vehicle to encounter each other on the basis of these two pieces of position information. A deriving section derives a distance between the vehicle and the other vehicle on the basis of these two pieces of position information. A determining section provides notification of an encounter with the other vehicle in a case where the estimated time is equal to or less than a first threshold value or in a case where the derived distance is equal to or less than a second threshold value.

Abstract: A first communication device stores a transmission rate table including response times, and transmission rates associated with the response times, each first response time indicating a time for transmitting test data between the first and second communication devices, while transmitting load data between any pair of communication devices at one of different transmission rates. The first communication device determine a necessary transmission rate for actual data; detect a response time indicating a time for transmitting the test data between the first and second communication devices; determine a transmission rate associated with the response time, as a used transmission rate, based on the transmission rate table; determine an effective remaining transmission rate based on a maximum transmission rate of the communication network and the used transmission rate; and start transmission of the actual data when the effective remaining transmission rate is higher than the necessary transmission rate.

Abstract: A wireless communication device mountable in a vehicle acquires first position information on the vehicle and receives a packet signal from another wireless communication device, the packet signal including second position information on another vehicle in which the other wireless communication device is mounted. The wireless communication device has a storage that stores log information and a controller. The controller predicts whether the vehicle crosses the other vehicle at a point of crossing based on the first position information and the second position information, estimates a structure of crossing corresponding to the point of crossing based on the history information, and determines, when it is predicted that the vehicle crosses the other vehicle at the point of crossing, whether or not to notify a presence of the other vehicle to a driver of the vehicle, in accordance with the structure of crossing corresponding to the point of crossing.
