Abstract

RF channel characterization in forging conceivable short-range wireless links in nano-through femto-cells applications of WLAN/WPAN in long term evolution (LTE) context is considered. Relevant next-generation wireless-based indoor services are required to support multi-gigabit information transfer rates. As such, the associated electromagnetic (EM) spectral needs warrant accommodating almost unlimited wireless channels each shouldering enormous bandwidth. Relevant wireless transport requirements can be met with the span of EM spectra that currently remain unclaimed and unregulated. They exist as prospective resources in the frontiers of mm-wave range (spanning 30 GHz to terahertz band). Addressed in this study thereof is the feasibility of conceiving “inferential prototypes” of RF channel-models in the 30+ GHz through THz spectrum of indoor ambient by judiciously sharing the “similarity” of details pertinent to already existing (known) “models” of traditional, lower-side EM spectrum, (namely, VLF through micro-/mm-wave); and, an approach based on the principle of similitude due to Edgar Buckingham is invoked toward model-to-(inferential) prototype transformations. Examples on indoor path-loss estimation for line-of-sight (LoS) case is presented for the spectral range of interest and the efficacy of the proposal is outlined.
LTE环境下毫米波/太赫兹频率下纳米至飞蜂窝环境的室内射频信道特性
考虑了在长期演进(LTE)环境下WLAN/WPAN的纳米到飞蜂窝应用中锻造可想象的短距离无线链路的射频信道特性。相关的下一代基于无线的室内服务需要支持千兆位的信息传输速率。因此,相关的电磁(EM)频谱需要保证容纳几乎无限的无线信道,每个信道都承担着巨大的带宽。相关的无线传输要求可以通过目前无人认领和不受管制的EM频谱范围来满足。它们是毫米波范围(30 GHz至太赫兹波段)前沿的潜在资源。在这项研究中,通过明智地分享与传统的(已知的)低侧EM频谱(即VLF到微/毫米波)的现有“模型”相关的细节的“相似性”,在室内环境的30+ GHz到太赫兹频谱中构想RF信道模型的“推理原型”的可行性;并且,基于Edgar Buckingham的相似原则的方法被用于模型到(推理)原型的转换。针对感兴趣的光谱范围,给出了室内视距(LoS)情况下路径损失估计的实例,并概述了该建议的有效性。
