    Some of the effects of tropical forests (jungle) on the performance of VHF radios have been explored. To better understand average propagation effects, the dielectric constant and the conductivity of selected forests have been measured. The effect of forests on the gain and pattern of simple VHF antennas has been explored, as well as signal loss along a trail. Scattering of VHF radio waves by near... View full abstract»

    In railway radio systems and vehicular communications, a very important problem is that of maintaining stable communications at all locations, especially in tunnels and in spaces between buildings. A leaky coaxial cable having a new type of slot as a radiating element combining longitudinal slots with circumferential slots is described, and the desired radiation power or coupling loss can be easil...

  • Data rate requirements for relay links in vehicular locator systems

    For the effective and efficient utilization of mobile vehicles, a vehicle locator and tracking system is necessary. Possible users of the system include the police, municipal bus systems, taxicabs, utilities, and others. One often suggested approach employs a network of distributed sensors, which sense and identify vehicles in the immediate vicinity. The sensors which receive transmissions from th...

  • Automation of the highways, an overview

    Publication Year: 1969 , Page(s): 77 - 80

    Highway automation systems must be evolutionary and begin with present vehicles and highways. Development of a simple vehicle tracker as an optional extra on new vehicles to control braking and accelerating on presently controlled-access highways is a necessary first step. Once this device is prevalent, contains built-in self-test, and has engendered public confidence, then automatic steering can ... View full abstract»

  • Note on FM transmission of video between moving vehicles over a flat earth

    A signal-to-interference ratio for the transmission of scanned images and digital data in the dynamic multipath environment was derived in an earlier paper. The dynamic case depends upon a Doppler environment-signal parameter ratio, while the static result is independent of the signal structure. The dynamic case is asymptotic to, but always worse than, the static one. For a Doppler-signal ratio of... View full abstract»

    Summary form only given, as follows. IEEE Standard 184, "IEEE Test Procdure for Frequency-Modulated Mobile Communications Receivers," has been completed after seven years of work by members of the G-VT Mobile Communications System Technical Committee. In February, 1962, the IRE Standards Committee requested that a review and updating of the then existent Standard 49 IRE 16.51 be undertaken by the ... View full abstract»

    This Test Procedure covers definition of terms, controlled test conditions, test apparatus, test methods, and data presentation, which form the basis for establishing performance criteria of mobile communication receivers designed to receive frequency-modulated waves in the frequency range from 25 to 1000 MHz. Specific limits are not included; however, reference values that are not limited by the ... View full abstract»
