“…Aware of the importance in studying the low-height communication-link propagation-characteristics, research has produced several empirical models [1]- [9]. Single-slope [1]- [3], [5], [6], [9], [10], two-slope [8], [11], and even three-slope [4] models have been proposed, which consider heights compatible with the lowheight channel of this study. In [12], measurements were conducted, at a very near to the ground level (receiver height at 3 to 28cm), at 880MHz, in an urban environment.…”

The evaluation of communication systems with low-height terminals requires path loss models that are applicable to low-height links. For the terminology low-height, the range 0.5 (mobile-) to 3m (fixed-node) above ground is considered. Herein, empirical non-time-dispersive propagation models for relaying systems with low-height terminals are proposed. The models consist of line-of-sight and non-line-of-sight branches. Single-and two-slope modelling approaches were examined. The models take into account the effect of frequency, transmitter and receiver height, and environment. They are complemented by shadowing and fast-fading distribution and correlation statistics. The performance of the models in producing accurate estimations is evaluated by comparison with sets of independent data.
