Communication system, communication method, and storage
A communication system is a communication system provided in a mobile body and including an acquirer configured to acquire a destination of the mobile body, and a communicator configured to communicate with a communication device outside the mobile body using an antenna, in which the communicator is configured to increase directivity of the antenna in a direction from a position of the mobile body to the destination when the destination is acquired by the acquirer.
1. A communication system provided in a mobile body and including an acquirer configured to acquire a destination of the mobile body, and a communicator configured to communicate with a communication device outside the mobile body using an antenna,
wherein the communicator is configured to increase directivity of the antenna in a direction of the destination higher than a direction other than the direction of the destination when the destination is acquired by the acquirer.
2. The communication system according to claim 1 , wherein the communicator is configured to increase the directivity of the antenna in a direction from a position after change to the destination when the position of the mobile body changes.
3. The communication system according to claim 1 , wherein the communicator is configured to increase reception sensitivity of the antenna when the destination is not acquired by the acquirer.
4. The communication system according to claim 1 ,
wherein the acquirer is further configured to acquire the position of the mobile body, and
the communicator is configured to decrease the directivity of the antenna or sets the antenna to nondirectional when a distance between the position of the mobile body and the destination is within a predetermined distance.
5. The communication system according to claim 3 , wherein the communicator is configured to increase the reception sensitivity of the antenna as the position of the mobile body approaches the destination.
6. A communication method comprising:
acquiring, by a computer provided in a mobile body, a destination of the mobile body;
communicating, by the computer provided in the mobile body, with a communication device outside the mobile body using an antenna; and
increasing, by the computer provided in the mobile body, directivity of the antenna in a direction of the destination higher than in a direction other than the direction of the destination when the destination is acquired.
7. A communication system provided in a mobile body and including an acquirer configured to acquire a destination of the mobile body, and a communicator configured to communicate with a communication device outside the mobile body using an antenna,
wherein the communicator is configured to increase directivity of the antenna in a direction from a position of the mobile body to the destination when the destination is acquired by the acquirer,
wherein the acquirer is further configured to acquire the position of the mobile body, and
the communicator is configured to decrease the directivity of the antenna or sets the antenna to nondirectional when a distance between the position of the mobile body and the destination is within a predetermined distance.
8. The communication system according to claim 7 , wherein the communicator is configured to increase reception sensitivity of the antenna as the position of the mobile body approaches the destination.
