Why is path loss important?
The path loss is an important factor regarding energy management, that is, maximum radio frequency (RF) output power, and data transmission quality, for wireless communication. The path loss as an indicator of the quality of the communication channel is influenced by any kind of matter within the signal path.
What is path loss in wireless channels?
Path loss, or path attenuation, is the reduction in power density (attenuation) of an electromagnetic wave as it propagates through space. Path loss is a major component in the analysis and design of the link budget of a telecommunication system.
What is path loss as applied to signals?
What is Path Loss? Path loss (PL) refers to the loss or attenuation a propagating electromagnetic signal (or wave) encounters along its path from transmitter to the receiver. As a result of path loss, the received signal power level is several orders below the transmitted power level.
Why does path loss increase with frequency?
When buildings and other structures are in the path, then there will be true energy absorption. In this case, materials generally absorb more energy the higher the frequency (for frequencies in the range of radio waves). In this way path loss can increase with frequency.
