FUTURE LAND-MOBILE COMMUNICATIONS

THERE IS A POTENTIAL DEMAND FOR 50 TO 100 TIMES AS MANY LAND-MOBILE FREQUENCIES AS ARE NOW AVAILABLE. COMPLETE SHARING OF FREQUENCIES AMONG USERS CAN PRESENTLY BE EXPECTED TO PRODUCE AN IMPROVEMENT ONLY BY A FACTOR OF 2. EVEN IF THE PRESENT UHF-TV FREQUENCIES WERE ASSIGNED TO LAND-MOBILE SERVICE, THIS WOULD NOT MEET THE POTENTIAL DEMAND. THE DEMAND MIGHT BE MET BY DEVELOPING SYSTEMS USING LAND-LINE SWITCHED NETWORKS WITH DISTRIBUTED FIXED TRANSCEIVERS TO MINIMIZE THE RADIATED POWER FOR THE MOBILE TRANSMITTER. THIS APPROACH HAS MANY OTHER BENEFITS SUCH AS REDUCED COST. STUDIES ARE NEEDED FOR THE DEVELOPMENT AND TEST OF SUCH A SYSTEM AS WELL AS THE VARIOUS FREQUENCY MANAGEMENT SCHEMES. /BPR/
