The previous point of view of worst case leads to an elevation angle of −1.87-degree and an attenuation of 170.77 dB. With this kind of attenuation, every system would be unusable! It was found also for this case that with the nominal elevation angle, the distance of the tangent point to ground is 5.84 km; that of the worst case is 2.69 km.
In telecommunications, the free-space path loss (FSPL) (also known as free-space loss, FSL) is the attenuation of radio energy between the feedpoints of two antennas that results from the combination of the receiving antenna's capture area plus the obstacle-free, line-of-sight (LoS) path through free space (usually air).

A link budget is an accounting of all of the power gains and losses that a communication signal experiences in a telecommunication system; from a transmitter, through a communication medium such as radio waves, cable, waveguide, or optical fiber, to the receiver.

It is possible to extrapolate the cumulative attenuation distribution at a given location by using the CCIR interpolation formula: [12] A p = A 001 0.12 p −(0.546 − 0.0043 log 10 p). where A p is the attenuation in dB exceeded for a p percentage of the time and A 001 is the attenuation exceeded for 0.01% of the time.
Walmart (NYSE: WMT) shareholders are basking in a record-setting year, with strong growth propelling the stock to a fantastic 81% return thus far in 2024, at the time of writing. In contrast ...
