发明名称 COMMUNICATION EQUIPMENT AND LAN SYSTEM IN VEHICLE
摘要 PROBLEM TO BE SOLVED: To provide communication equipment which can be moved to a position satisfactorily communicable for a user. SOLUTION: In the communication equipment 3, the signal strength of a received signal outputted from a receiving part 13 for receiving a transmitted radio wave from external communication equipment 5 is detected by a signal strength detecting part 17 and signal strength data are inputted to an MPU 30. When the signal strength data are received, the MPU 30 displays receiving sensitivity information on the signal strength on a display 40 by correlating the signal strength data with equipment information 51 corresponding to that signal strength, so that the receiving sensitivity of the communication equipment 3 can be reported to the user for each of communication equipment 5. Therefore, in such communication equipment 3, the user can grasp which communication equipment 5 is in the state of adverse communication environment on the basis of the receiving sensitivity and by moving the communication equipment 5 on the basis of the receiving sensitivity information, the communication equipment 5 can be installed in the place of satisfactory communication environment.
