Definition and Effect of Reflection, Diffraction, Scattering and Multipath Propagation in RF Engineering

Reflection Diffraction and Scattering in wireless communication When any new site has been planned then it should be such a way the effect of Reflection, Diffraction, Scattering and Multipath should be Balance. Reflection¬†in wireless communication Reflections Occurs when a wave…

Inter-Symbol Interference in LTE

What is the multipath? Due to the signal propagation phenomena, like reflection or diffraction, a receiver can receive several delayed versions of the same signal. This creates Inter-Symbol Interference (ISI). The multi-path impact is an overlapping of 2 symbols, called…

Propagation Path

Radio wave can be propagated from the transmitting antenna to the receiving antenna in many ways: perpendicular incidence wave or ground refraction wave, diffraction wave, troposphere reflection wave, ionosphere reflection wave, as shown in the diagram. As for radio wave,…

Propagation of Electromagnetic Wave

When the radio wave propagates in the air, the electric field direction changes regularly. If the electric field direction of radio wave is vertical to the ground, the radio wave is vertical polarization wave If the electric field direction of…

Radio Wave Spectrum

The radio waves are distributed in 3Hz ~ 3000GHz. This spectrum is divided into 12 bands, as shown in the above table. The frequencies in each specific band present unique propagation features: The lower the frequency is, the lower the…
