Abstract
In order to reduce wire connections and achieve a wireless communication environment securing a sufficient communication band, the present invention provides a communication apparatus that includes a wireless communication means for transmitting and receiving a wireless signal, an optical communication means for transmitting and receiving spatial light as communication light, and a control means for performing signal conversion in a process for converting the wireless signal and the communication light and setting a transmission destination of the wireless signal and the communication light.
Claims13
A communication apparatus comprising:
- a wireless communicator configured to transmit and receive a wireless signal;
- an optical communicator configured to transmit and receive spatial light as communication light;
- and
- a controller configured to perform signal conversion in a process for converting the
- wireless signal and the communication light and, the controller is configured to set a transmission destination of the wireless signal and the communication light, wherein
- the optical communicator expands, upon interruption of communication with a communication target, an irradiation range of the communication light, and transmits the communication light toward another apparatus responding to the communication light of which the irradiation range is expanded.
A communication method comprising:
- arranging a plurality of communication apparatuses each including a wireless communicator configured to transmit and receive a wireless signal, an optical communicator configured to transmit and receive spatial light as communication light, and a controller configured to perform signal conversion in a process for converting the wireless signal and the communication light and, the controller configured to set a transmission destination of the wireless signal and the communication light;
- and
- performing control in such a manner that the different communication apparatuses communicate with each other by using the communication light, wherein
- expanding, upon interruption of communication with a communication target, an irradiation range of the communication light, and transmits the communications light toward another apparatus responding to the communication light of which the irradiation range is expanded.
