Table 2 K value correction coefficient term of SPM model

From: Research on TD-LTE wireless communication network propagation model optimization based on visual simulation and GIS

K value Coefficient meaning Whether to correct
K1 Constant loss, frequency dependent Y
K2 Transmission distance loss Y
K3 Loss factor caused by changes in base station antenna height N
K4 Diffraction loss, only hilly terrain will be considered N
K5 Influence of base station antenna height and propagation distance on received power N
K6 Gain caused by changes in antenna height at the receiving end, when the terminal height is 1.5 m, usually set to 0 N
Kclutter Various ground loss, the default value is 1 N
