Which two factors cause delayed signals and multipath related issues?
Radio Frequency Systems
That greater distance causes the secondary (multipath) signal to be delayed by a factor of the greater distance and the wavelength of the frequency of the channel on which it is operating.
What is multipath signal propagation?
Multipath propagation, an inherent feature of a mobile communications channel, results in a received signal that is dispersed in time. Each path has its own delay and the time dispersion leads to a form of intersymbol interference. Delay spread is a measure of the multipath profile of a mobile communications channel.
How do you overcome multipath propagation?
Before you clear the office of all its furniture or cut down that tree in your backyard, there is a simple way to reduce the effect of multipath and the answer is spatial diversity. Spatial diversity is usually achieved by having two or more antennas connected to separate radios inside a wireless device.
How multipath propagation affects signal quality?
When the same signal is received over more than one path, it can create interference and phase shifting of the signal. Destructive interference causes fading; this may cause a radio signal to become too weak in certain areas to be received adequately.
