    At a base station of a UHF mobile radio telephone system in a large city, many transmitters are used. In such a case it is not practical to use an individual antenna for each transmitter from the viewpoint of system economy and interference. Common use of one antenna for many radio-frequency channels is suitable and transmitter multiplexing devices should be used for this purpose. A transmitter mu... View full abstract»

    START (system of transportation applying rendezvous technology) is a side-by-side rendezvous technique designed to improve the collection and transfer of passengers in a rail-guided intercity transportation system. In operation, a nonstop express train provides service between cities, while frequent-stop local trains are used to provide coverage of metropolitan areas. The local trains link up with...

    Directed toward FCC Docket 16073 on air-ground telephone service by single sideband, a study has been made of a high channel density 450-MHz communication system employing 6 groups of 10 channels each in a 300-kHz band. To accomplish necessary tolerance to out-of-band transmitter radiation, all mobile stations need automatic power output control. Other important system features, such as privacy an...

  • Conversion of a VHF communications system from standard to tone squelch

    Publication Year: 1969, Page(s):28 - 32

    This paper describes the original VHF mobile radio system in the Indiana and Michigan Electric (I&ME) Company and how it operated with standard squelch. It points out some of the problems which were encountered at the relatively low operating frequency in the 37-MHz region and goes on to show the solution for most of these problems by converting the entire system of 19 base stations and 300 mo...

    The use of walkie-talkie radios to supplement fixed wire interior communications systems on ships is discussed. Electrical and acoustical noise interference problems were studied on replenishment ships, and the use of FM at VHF together with noiseproofed acoustic transducers was found necessary for many operations and/or for men in certain locations. RF signal penetration tests showed VHF to be su... View full abstract»

  • Human factors in command and control

    Several human factors considerations in the design of command and control systems are viewed from the aspect of three common classes of human system participants: the sensors, the filters, and the decision makers. An attempt is made to demonstrate the effects of particular perceptual variables upon the performance of each of these classes of participants. Several suggestions are made, based on rec...

  • Effects of multipath transmission on the measured propagation delay of an FM signal

    Position location techniques based on propagation delay have been proposed previously. A narrow-band version of this technique involves the transmission of RF carrier, modulated by a single audio frequency. At a receiver, the audio phase is a measure of distance provided the propagation delay is less than one quarter cycle. The transmission medium introduces multipath distortion and the received s...

    A digital radio dispatch system for control of mobile forces offers improvements over some of the shortcomings of existing voice systems. The four functions involved in dispatching--- signaling, message, acknowledgment, and status---are described. Both the remote station and control center operations are described with emphasis placed on message format and timing. Polling controls the mobile tracs... View full abstract»

    There are two basic types of car location schemes. One uses time measurement and computes location by generalized triangulation; the other identifies location by proximity to one of a multitude of receivers or transmitters which have been permanently installed. The principal problem with the latter system is installation. By taking advantage of existing grids or networks of units, in this case pol... View full abstract»

    Mobile teleprinters are looking increasingly attractive to vehicular communication system engineers, especially as automation enters the dispatching scene. A dot matrix page printer is described. The dot matrix approach enables the use of visual error correction since noise generally appears as miscellaneous extra or missing dots. The character remains recognizable. Although the operation of the p... View full abstract»

    The automatic mobile director and reporting system (AMDRS) was designed to provide continuous control of each field unit. Consisting of three major subsystems: control center, command computer, and field unit, AMDRS is intended to provide real-time control with a minimum radio-frequency spectrum usage. Both the control center and the field unit make use of visual displays. An automatic vehicle loc... View full abstract»
