Abstract: A communication apparatus transmits a search signal including information based on a character string input by a user, the search signal being used to search for a providing apparatus that provides a communication parameter. Upon reception of a response to the search signal, the communication apparatus starts communication parameter sharing processing with a providing apparatus that has transmitted the response.

Abstract: A communication apparatus determines whether the communication apparatus is connected with a wireless network, and accepts an instruction for starting setting processing of a communication parameter, which is used in performing wireless communication, with another communication apparatus that has read an image including information about a frequency channel used in the setting processing. If the communication apparatus is determined to be connected with the wireless network, the communication apparatus does not start waiting for a request for the setting processing even when the instruction is accepted. If the communication apparatus is determined not to be connected with the wireless network, the communication apparatus starts waiting for the request for the setting processing in response to acceptance of the instruction.

Abstract: A communication apparatus includes a generation unit that generates an image including information about a frequency channel used for executing wireless communication and a communication unit that communicates with another communication apparatus that has read the generated image using the frequency channel included in the image. When the communication apparatus is connected to the wireless network, an image including information about a frequency channel used for the connected wireless network is generated, and when the communication apparatus is not connected to the wireless network, an image including information about a predetermined frequency channel is generated.

Abstract: A communication apparatus connectable to a wireless base station, the apparatus comprises a first obtaining unit configured to obtain a moving speed of the communication apparatus; a second obtaining unit configured to obtain a moving speed of the wireless base station; and a control unit configured to control connection to the wireless base station based on the moving speed of the communication apparatus and the moving speed of the wireless base station.

Abstract: A search signal is either transmitted or waited for, in accordance with a role in a service specified by an upper-level application.

Abstract: When information for setting communication parameters includes predetermined information, a communication apparatus performs an authentication process involving wireless communication of authentication information generated using random information and information for use in the authentication process included in the information for setting the communication parameters. When the information for setting communication parameters does not include the predetermined information, the communication apparatus performs an authentication process involving wireless communication of authentication information generated using information for use in the authentication process and without using the random information.
