“…In the end, it was concluded that no single path loss model was able to predict path loss consistently. In [18], a comparative assessment of five models was presented with respect to the data collected in the urban and suburban environments at 910 MHz. However, the paper does not provide a conclusion about which model gives the best results.…”

“…Specifically, the Delisle statistical terrain diffraction loss estimate (Ld ∆h) is selected by running Microsoft Excel Solver's nonlinear optimization tool on the first drive test data. According to Delisle et al (1985), Ld ∆h) value of 15 is set as the minimum and 400 as the maximum. The Microsoft Excel's Solver nonlinear optimization is run with the condition that 15 P Ld ∆h P 400 and the objective is to minimize the root mean square error between the measured pathloss in the first drive test and the Blomquist-Ladell model predicted pathloss.…”

“…Where h is the height of transmitter above ground in m h is the height of receiver above ground in m d is the distance between transmitter and receiver along line of sight path in km d D is the distance between transmitter and receiver along line of sight path in m (1000d) f is the carrier frequency in MHz λ is the carrier wavelength in m ϵ is the dielectric constant (relative permittivity) of the ground (Delisle recommends ϵ =10 for dry earth [12].…”
