Radio Propagation above 40 MC over Irregular Terrain

Tropical Propagation Research

“…At 100 mc, the vehicular data indicates that horizontal polarization is better by 10 db, a conclusion which is [4][5][6][7] I again consistent with the conclusions drawn from the fixedpoint data. At 250 mc, there is only a small difference between horizontal and vertical polarizations for the vehicular data.…”

Urban Area Path loss Propagation Prediction and Optimisation Using Hata Model at 800MHz

“…Several existing path loss models such as Hata's Model [5], Stanford University Interrim (SUI) model [6], Lee's Model [7] and Egli's Model [8] are chosen for comparison with measurement data. The best existing path loss model with the closest propagation exponent [8], to the measured path loss data will be chosen as a reference for the development of the optimized path loss model.…”
