    Descriptive and statistical analyses of radio propagation data over irregular terrain are presented with emphasis on communications between low antennas in VHF and UHF bands. Measured data are evaluated for medians and ranges of basic transmission loss and height gain, and results are compared with estimates from a propagation model developed by the Institute for Telecommunication Sciences. Effect... View full abstract»

    Optimum utilization of patrolling vehicles requires that the central controller be continuously informed about their location. To meet this need, a purely mechanical analog computer was designed, built, and tested. The results obtained show that systematic errors introduced by the system far outweigh random errors and that this concept is feasible as a location interpolator between fixed known ref...

    Diversity is often used in radio systems to alleviate the problem of fading. It is shown here that the use of diversity in a mobile radio system also will result in better utilization of the frequency spectrum. In a system which reuses channels in physically separated areas, probability distributions of signal-to-cochannel interference ratios in 1-, 2-, and 4-branch diversity systems are developed...

    The concept of a small-zone system plan for mobile telephone service is reviewed, as are the advantages of spectrum economy, flexible growth, low power requirements, and wide channel spacing and the disadvantages of locating mobiles and establishing base-station sites. The functions which such a system must perform are enumerated. A call processing sequence and a mobile block diagram which perform... View full abstract»
