RADIO COMMUNICATION EQUIPMENT

Japanese Patent JP3189663

B2

PROBLEM TO BE SOLVED: To simplify the equipment and to reduce the power consumption by storing cone position information to a memory and sending the information to an opposite party via a radio section after communication restart so as to receive a control signal while keeping the communication and to send position information thereby realizing the communication with one system of reception section.
SOLUTION: An electric field strength of a base station measured by a reception electric field strength measurement 3 during communication is compared with a prescribed valve at an electric field strength comparison section 4 and when the electric field strength is less than the prescribed value, communication is interrupted, a frequent setting section 6 revises a control signal transmission frequency of a base station, an identification code of a peripheral base station is detected and the reception electric field strength is stored in a memory 6. After one of peripheral base stations is selected and communication is restarted, the identification code of the peripheral base station stored in the memory 6 and the reception electric field strength are inputted in the signal processing section 2, in which they are coded and the result is sent to a radio section 1. Thus, the change in a position of the radio communication equipment during communication is detected to realize the transmission of position information through one system of reception section and the configuration of the radio communication equipment is simplified.
