The two-ray model has been used for modelling of wireless channels already for decades. However, since researchers and industry are pushing forward to unlock the millimeter wave bands, we revisited this model. We re-derive the break point distance based on a generalized first Fresnel zone. The simplified approximation formula — four times the product of antenna heights scaled by wavelength — is especially...
In the race towards ultra-high-data-rate wireless communication systems, terahertz (THz) band communication is envisioned as a key wireless technology to satisfy this demand and overcome the spectrum scarcity of current wireless systems. As more and more users prefer to accessing digital information with mobile device anytime and anywhere, the close proximity data transfer are needed. In this paper,...
