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).

Examples of estimated bandwidth of different antennas according to the schedule VSWR and return loss by the help of the ANSYS HFSS [1]. Ansys HFSS (high-frequency structure simulator) is a commercial finite element method solver for electromagnetic (EM) structures from Ansys.
For the 12th time in 50 years, Walmart will conduct a stock split in an effort to make shares more affordable for its employees. Walmart last carried out a 2-for-1 stock split on April 20, 1999.
The Hata model is a radio propagation model for predicting the path loss of cellular transmissions in exterior environments, valid for microwave frequencies from 150 to 1500 MHz.
The 2-ray ground reflected model may be thought as a case of multi-slope model with break point at critical distance with slope 20 dB/decade before critical distance and slope of 40 dB/decade after the critical distance. Using the free-space and two-ray model above, the propagation path loss can be expressed as
Walmart has $93 billion invested in the businesses, with its largest stakes in Flipkart (84%) and PhonePe (84%). Drbul determined Walmart's stock is worth $180, roughly 12% higher than current levels.
On March 21, 2024, Walmart stock reached a record closing high of $61.45 per share. So far this year, its shares are already up 14%, beating the S&P 500's ( ^GSPC ) 10% gain.
