“…1(b), the indoor environment is usually divided into a number of subspaces by the walls with two orientation angles that are perpendicular to each other in most cases. In our work, we consider to employ Manhattan Poisson line processes (MPLPs) to describe the wall blockage model [32]. In particular, the walls are assumed to be oriented perpendicular to the coordinate axes and modeled as two independent MPLPs, whose centers are distributed according to two one-dimensional Poisson point processes Φ x and Φ y with the same density λ W along x-axis and y-axis, as shown in Fig.…”

Providing high-bandwidth and fast-speed links, wireless local area networks (WLANs) in the Terahertz (THz) band have huge potential for various bandwidth-intensive indoor applications. However, due to the specific phenomena in the THz band, including severe reflection loss, indoor blockage effects, multi-path fading, the analysis on the interference and coverage probability at a downlink is challenging. In this paper, indoor blockage effects caused by the walls and human bodies are analyzed. Next, a statistical THz channel model is proposed to characterize the THz indoor propagation. In light of these, the moment generating functions of the aggregated interference and theoretical expressions for the mean interference power are derived. As a result, the approximated coverage probability and average network throughput are derived. Extensive numerical results show that for the nearest access point (nearest-AP) user association scheme, the optimal AP density is 0.15/m 2 , which results in the coverage probability reaches 93% and the average network throughput is 30 Gbps/m 2 . In addition, by adopting a novel line-of-sight access point (LoS-AP) user association mechanism, the coverage probability and the average network throughput can be further improved by 3 percent and 2 Gbps/m 2 , respectively.

“…where Q * ≥ 0 is the sensitivity of the energy harvester and R * ≥ 0 is the minimum achievable rate. A convenient reformulation of the J-CCDF has been proposed in [11], and it amounts to DRAFT January 14,2018 computing the probability that the multi-user interference belongs to an interval for which a minimum SINR γ can be achieved conditioned to a minimum amount of received power q * , i.e.…”

Simultaneous information and power transfer (SWIPT) is characterised by the ambiguous role of multi-user interference. In short, the beneficial effect of multi-user interference on RF energy harvesting is obtained at the price of a reduced link capacity, thus originating nontrivial trade-offs between the achievable information rate and the harvestable energy. Arguably, in indoor environments, this tradeoff might be affected by the propagation loss due to blockage objects like walls. Hence, a couple of fundamental questions arise. How much must the network elements be densified to counteract the blockage attenuation? Is blockage always detrimental on the achievable rate-energy trade-off? In this paper, we analyse the performance of an indoor multiple-input multiple-output (MIMO) SWIPT-enabled network in the attempt to shed a light of those questions. The effects of the obstacles are examined with the help of a stochastic approach in which energy transmitters (also referred to as power heads) are located by using a Poisson Point Process and walls are generated through a Manhattan Poisson Line Process. The stochastic behaviour of the signal attenuation and the multi-user interference is studied to obtain the Joint Complementary Cumulative Distribution Function (J-CCDF) of information rate and harvested power. Theoretical results are validated through Monte Carlo simulations. Eventually, the rateenergy trade-off is presented as a function of the frequency of walls to emphasise the cross-dependences between the deployment of the network elements and the topology of the venue.A.

“…These blockages are then used to determine the LOS or NLOS state of every link; additionally, blockages are used to switch between indoor and outdoor propagation models. Also investigations of the actual influence of blockages in a scenario can be performed, similar to [53]. To do so, blockages are assigned a penetration loss value, which can be the same for all walls, stem from a distribution of loss values, or can be predefined, which then allows to calculate the accumulated penetration loss along the link.…”

The investigation and prediction of new trends and technologies for mobile cellular networks is of utmost importance for researchers and network providers to quickly identify promising developments. With the verge of the fifth generation of mobile communications (5G), networks become more and more heterogeneous and dynamic while the amount of active users within a cell keeps ever increasing. Therefore, the search for more efficient network layouts and configurations attracts massive attention while on the other hand becomes more and more complex. In this contribution, we present the Vienna 5G system level simulator, which allows to perform numerical performance evaluation of large-scale multi-tier networks, with numerous types of network nodes. The simulator is based on MATLAB and is implemented in a modular fashion, to conveniently investigate arbitrary network and parameter constellations, which can be enhanced effortlessly. We first discuss the distinguishing aspects of our simulator platform, describe its structure, and then showcase its functionality by demonstrating the key aspects in more detail.
