Measurements and Modeling of Path Loss over Irregular Terrain for Near-Ground and Short-Range Communications
In this paper, radio wave propagation over irregular terrain is investigated in 200–600MHz (VHF/UHF band). Measured results are compared with different path loss models such as Fresnel knife edge diffraction and uniform theory of diffraction (UTD). It is shown that, for low antenna heights, using a combination of the two-ray path loss model and knife-edge diffraction, great improvement in path ...
متن کاملModeling Near-earth Groundwave Propagation over Random Terrain Roughness with an Effective Low-grazing Reflection Coefficient
Accurate characterization of the electromagnetic wave scattering and propagation properties of the terrain surface is essential in optimizing the performance of wireless sensor networks (WSN) deployed for environmental monitoring and geophysical sensing applications. As the WSN nodes are positioned near or at the ground level, the conditions of the ground have a substantial effect on the radio ...

متن کاملPropagation studies at Ku-band over an earth-space path at Kolkata
Propagation measurements at Ku-band over an earth-space path have been carried out at Kolkata (22°34′ N, 88°29′ E) by receiving a signal at 11.172 GHz from the satellite NSS-6 (geostationary at 95°E). The amplitudes of the co-polar signal and the cross-polar component have been monitored along with the measurements of rain rate and drop size distribution by an optical raingauge and a Joss-type ...
متن کاملInvestigation of Path Loss of Mobile Radio Services at L-Band Frequency over Akure, South Western, Nigeria
As the migration of wireless communication network from one generation to another continue, radio wave propagation model or path loss model plays a very significant role in achieving an optimum performance as well as suitability over different locations of interest. In this research, investigation of radio communication channel behavior based on practical measurement in the L-band frequency in ...
