Formula for Link Budget Calculator It includes losses from cables/fibers and other components in the Tx/Rx chain, gains from the antenna, amplifiers etc. and propagation loss when travelling through air or another medium. Received power (dBm) = Transmitted power (dBm) + gains (dB) - losses (dB)

A simple link budget equation looks like this: Received power (dBm) = transmitted power (dBm) + gains (dB) ? losses (dB)

(A) ? A fundamental relation in antenna theory is gain & area of an antenna are related by G = 4? Ae / ?2 ? Substituting above equation in equation (A) gives Pr = [Pt Gt Gr/ (4 ?R / ? )2 ]watts ? This expression is known as link equation & essential in calculation of power received in any radio link.

A link budget calculation is important when designing a communication system in order to ensure that the system will operate as intended over it's expected distance and power levels. If the resulting received signal strength (expressed in dBm) is too low, changes to the system may need to be considered.

The amount of margin required can be reduced by the use of mitigating techniques such as antenna diversity or MIMO (Multiple Input Multiple Output). A simple link budget equation looks like this: Received power (dBm) = transmitted power (dBm) + gains (dB) ? losses (dB)

In essence link budget is like a set of calculations giving the feasibility and performance summary of a particular communication link from the transmitter to the receiver end. In case of satellite, which is a moving object it is calculated for the whole region, from where you want to receive, typically a cone.
