Abstract: A communication system including a first and second communication apparatus is provided. The first communication apparatus includes first communication means for communicating with the second communication apparatus using the system information, and first setting means for setting the system information in the first communication means. The second communication apparatus includes second communication means for communicating with the first communication apparatus using the system information, and second setting means for setting the system information in the second communication means. The system information is commonly determined for all of the first and second communication apparatuses. The first and second setting means exchange new system information inputted by a user or given in advance with the second or first communication apparatus after communication is established, and set the new system information in the first or second communication means, respectively.

Abstract: A communication system is provided for performing communication by setting system information, which includes a first communication apparatus having communication control means for setting system information, communication means based on the system information, system information storage means, and system information providing means for providing a user with the information; and a second communication apparatus having communication control means for setting the information, communication means, system information storage means, and system information input means; wherein the first communication apparatus reads the information from the storage means, the system information providing means provides the user with the information, the user inputs the information to the second communication apparatus to share the information, and communication with the second communication apparatus starts; and when the information is input, the second communication apparatus stores the input information in the system information

Abstract: A communication control method for a communication apparatus for performing communication in conformity with predetermined communication standards among a plurality of communication apparatus by setting predetermined system information common to the communication apparatus, the communication apparatus performing communication with another communication apparatus having authentication processing means for executing an authentication process in accordance with authentication information: wherein a communicable state is established by making setting of lowering an output level of a transmission signal and discarding reception data having a reception signal level lower than a predetermined value and by making setting of common setting system information; a signal representative of a connection start is transmitted through communication based on the common system information; the authentication information input is transmitted; new system information authenticated by the authentication information is received; the
