What is received power in wireless communication?
In radar, the amount of power received at the antenna after being scattered by a target. This power is normally on the order of microwatts as compared with the kilowatts or megawatts of transmitted power. By convention, received power is measured in decibels relative to a reference value of 1 mW, that is, in dBm.
How is received signal power calculated?
Received Power Formula
To calculate a received power, multiply the antenna gain by the transmitted power, then divide by the product of the frequency squared times the propagation distance squared.
What is received signal in communication?
In telecommunications, received signal strength indicator (RSSI) is a measurement of the power present in a received radio signal.
Why received power is negative?
The reason you see negative values is that they are representing small but positive numbers, on a logarithmic scale. In logarithms, the value indicated represents an exponent... for example, under a log 10 scale, a value of -2 represents 10 to the -2 power, which equals 0.01.
