IPC: H04Q9/00
Filed: 2000-04-28
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a conventional remote control wireless system causes a beat interference due to a very small difference between transmission frequencies when a mobile station receives radio waves nearly in the middle of base stations because the electric field strength of the radio waves sent from both base stations is the same or 1/2 or twice or below nearly in the middle of the base station adjacent to each other when the base stations transmit the radio waves at the same time through the remote control by a command console in a wireless system where the base stations of the same communication frequency are distributingly placed in order to ensure a prescribed service area and the conventional system needs periodic readjustment because the oscillated frequencies of crystal oscillation circuits are deviated little by little due to change over time or a  temperature change although the beat interference is reduced through the adjustment of the trimmer capacitor of the crystal oscillation circuit deciding the transmission frequency. SOLUTION: Controlling communication frequencies of all base stations by a transmission control signal sent fro a command console for remote control can mach the transmission frequencies of the base stations so as to prevent the beat interference.
