Detailed explanation-1: -Explanation: I Path loss is defined as difference of effective transmitter power and receiver power. Free-space path loss is the loss in signal strength of an electromagnetic wave that would result from a line-of-sight path through free space, with no obstacles nearby to cause reflection or diffraction.
Detailed explanation-2: -A receiver must be able to receive signals with a power level of −20 dBm or higher and maintain PER of less than 1% to be compliant with IEEE 802.1.
Detailed explanation-3: -The received power level depends on the path loss. More the path loss, less is the available received power. We aim to reduce the path loss to maximize the power level available at the receiver.
Detailed explanation-4: -Radio propagation models are broadly classified into large scale and small scale models. Large scale effects typically occur in the order of hundreds to thousands of meters in distance. Small scale effects are localized and occur temporally (in the order of a few seconds) or spatially (in the order of a few meters).
