  • Characterization of UHF radio propagation channel in curved tunnels

    We propose an imperfect waveguide model to represent empty curved tunnels. We use the field configuration in an optical dielectric guide together with the surface impedance boundary condition for the walls to simplify the complexity of derivation of the propagation modal equations. The curvature of the tunnels is assumed to be gentle. Our results show that increased propagation loss is almost linearly proportional to frequency and inversely proportional to the radius of curvature.

  • Effective Earth radius factor characterization for line of sight paths in Botswana

    The ITU has adopted new methods for predicting the deep-fading distribution due to multipath propagation for the average worst month over UHF and SHF terrestrial line-of-sight links. These methods employ refractivity gradient statistics available from world maps, and are recommended for application in all regions of the world. In this regard, significant progress in the global climatological modeling of the main propagation effects in clear-air and precipitation conditions have been reported (Olsen, R.L. and Tjelta, T., IEEE Trans. Anten. and Propag., vol.47, no.1, 1999; Olsen, Proc. 3rd Regional Workshop on Radio Communications in Africa, 1999), with an attempt to relate the results to the African continent. D.C. Baker and A.J. Palmer (see Trans. SAIEE, vol.93, 2002) have proposed a model for the cumulative distributions of the fraction of times of occurrence for certain values of the k-factor for South Africa. They have assumed, based on earlier reports, that a normal distribution for the pdf of the k-factor is appropriate. We develop an empirical model for the k-factor distribution based on radiosonde data for Botswana. We model the distribution for the months of February, May, August and November, as per ITU-R practice, at height ranges of 0-500 m and 0-200 m above ground level

  • Characterization of radio wave propagation into buildings at 1800 MHz

    The paper presents the results of signal strength measurements at 1800 MHz in four office buildings in The Hague, illuminated by an outdoor base station with an antenna above the rooftop. The objectives of these experiments are to study the behavior of the received signal strength at different floors of a building and to determine the main characteristics concerning cell coverage, namely, signal attenuation and variation within these buildings. It is shown that large fluctuations occur between average signal levels in line-of-sight (LOS) and non-LOS areas of multifloor buildings.

  • Effect of space diversity technique in UHF band radio indoor propagation

    In order to clarify the receiving condition in the whole room, in this paper, the received level contour map is created based on the measured data of the UHF band radio wave in the indoor environment. Moreover, this paper investigates the effects of applying the space diversity technique that have been well known to be effective techniques to improve the deep fading considering the space uncorrelation of the received level (M. Schwartz et al.) By use of the measured level data, in order to clarify the space diversity effects in the indoor environments, the correlation coefficients between two branches and the cumulative probabilities of the received level are evaluated in case that the space diversity techniques with selection combining are applied.

  • Short Range Device (SRD) propagation modeling for Indoor environment

    In building propagation measurements, in the frequency band of 433 MHz are presented for narrow band applications, short range devices especially active and passive radio frequency identification (RFID). The propagation model based on 3D FDTD (finite difference time domain) simulation is proposed and the simulated results are compared with measured ones. The memory and computational time requirements are analyzed for a complex environment.

  • Transmission line method for propagation characteristic of electromagnetic wave in rectangular tunnel

    The paper presents the equivalent transmission line equation which is useful to describe the propagation characteristics of electromagnetic waves in a tunnel. For the transmission line theory, the mathematical structure of the classical telegrapher equation was preserved, while the coefficients (the per- unit-length parameters) were generalized in order to represent the essential characteristic of the wire structure. At frequencies in the range of 200-4000 MHz transmission takes the form of waveguide propagation in a tunnel, since the wavelengths of the UHF waves are smaller than the tunnel dimensions. So, the tunnel is equivalent to the lossy uniform transmission lines under this condition. In the waveguide structure of the tunnel, the equivalent voltage and current must be introduced, which is called the equivalent transmission line theory. In this paper, the calculation of parameters for many propagation modes in a tunnel is ended to the solution of active equivalent transmission line equation. As examples, the coefficients of equivalent circuit and the attenuation rate for the dominant mode of the vertical polarization electromagnetic wave in the rectangular tunnel are computed. Consistent results with the pattern matching theoretical ones are obtained, and the validity of the presented method is thus verified.

  • The UHF method for measurement of partial discharge and interference suppression

    In recent years, the ultra high frequency (UHF) method is employed to reduce and avoid the noises effects on partial discharge (PD) detection for the power transformer on-site. In order to know the UHF signal radiation from the partial discharge in oil impregnated insulation and its propagation characteristics in a transformer tank, the experiments have been carried out in high voltage laboratory. The current impulse waveforms of PD and its UHF signals are measured through the partial discharge detecting circuit and a coupler, respectively. The results show that the electromagnetic wave can be excited from the partial discharge in oil-impregnated insulation with the higher frequency than that in air. The propagation and attenuation characteristics of UHF signals in a metal tank are different from that in opening air. The experimental results also show that the UHF signal can be radiated from the inside of a metal tank through a wire, which makes it possible to measure partial discharge for the power transformer with the coupler fixed at the outside of the tank.
