    Parameters of a large-scale highly coordinated mobile telephone system are discussed, particularly those of system size and frequency spectrum required. The concept of small-zone coverage areas to serve large customer densities is discussed, and the essential properties of small-zone systems are generalized to show that zone size alone is not an adequate parameter to distinguish large- from small-...

    High accuracy is not required for car locator systems used in police operations. Relatively inaccurate patrol car locator devices can greatly improve police operations by significantly reducing response time, by permitting dynamic redeployment of forces, and by providing for better administrative control of forces. The patrol car emitter-call box sensor technique could also be used on passenger bu... View full abstract»

    The IEEE Third Symposium on Vehicular Communications Systems was held on 13 May 1969, in Los Angeles, CA, USA, and treated the subject of electromagnetic spectrum utilization. This subject is very broad in scope and very timely in that the recent release of the JTAC report entitled "Spectrum engineering - the key to progress" should produce a long needed reevaluation of the approach to electromagn...

    The following fundamental technical questions concerning the use of the spectrum allocated to the land mobile radio service are discussed. 1) Is it technically feasible to increase the number of assignable channels within the allocated spectrum space? 2) Are other modulation methods more or less suitable for providing more channels? The primary resource material used to answer these questions is t... View full abstract»

    The dispersed array mobile radio system represents a radical new approach to the problem of spectrum congestion in the land-mobile radio service. This new approach provides a very substantial improvement in spectrum utilization over the present mode of operation and at a cost to the user of about 20 percent less. Spectrum efficiency is achieved by a dynamic combination of space, time, and frequenc... View full abstract»

  • The range and frequency dependence of VHF—UHF man-made radio noise in and above metropolitan areas

    The surface distribution of composite incidental man-made radio noise power in metropolitan areas displays frequency and range variations which are predictable from a knowledge of the propagation characteristics of irregular surface terrain for low-height antennas and the noise-source spectral power densities for a Poisson distributed random noise process. The observed frequency variation of compo... View full abstract»

    The very large increase in the use of the radio spectrum has resulted in numerous cases of spectrum congestion, and the continuing growth in spectrum-using devices can only result in increasing instances of congestion. With the objective of gaining fuller and more detailed understanding of spectrum congestion than has previously been available, Stanford Research Institute has been making an intens...
