NEW TECHNIQUES FOR MOBILE RADIO

TECHNICAL ADVANCES AT BELL LABORATORIES AND THE RECENT ALLOCATION OF NEW RADIO FREQUENCIES BY THE FEDERAL COMMUNICATIONS COMMISSION RAISE HOPES THAT MOBILE TELEPHONES WILL BE A REALITY FOR MILLIONS OF CARS, TRUCKS, AND BUSES. THE PICTURE BRIGHTENED CONSIDERABLY WHEN A FREQUENCY BAND 75 MHZ WIDE IN THE UHF REGION AROUND 850 MHZ WAS MADE AVAILABLE. BY USING ULTRAHIGH FREQUENCIES, LOW-POWER TRANSMITTERS, SMALL COVERAGE ZONES, AND VERSATILE EQUIPMENT, DESIGNERS APPEAR TO HAVE THE TOOLS TO SOLVE THE PROBLEMS OF THE PRESENT LIMITED MOBILE TELEPHONE SERVICE AND HELP ESTABLISH A TRULY HIGH-CAPACITY MOBILE SYSTEM. /AUTHOR/
