Performance of Indoor Small-Cell Networks Under Interior Wall Penetration Losses

“…For indoor environments, the authors in [2], [5], [18], [19] studied the performance of SCNs considering the modelling of building structures. The authors in [18] developed a spatial model of in-building SCNs and investigated the correlated shadowing among the links passing through the walls and ceilings.…”

“…In [5], the LOS probability was derived for practical indoor layouts with interior walls and ceilings, but indoor wireless coverage performance was not studied in [5], [18]. In [2], the authors developed a tractable SCN model for a multi-story building and investigated the influence of ceilings on the network coverage and capacity. In [19], the locations of indoor small-cel BSs in a building were modelled following a 3D PPP.…”

“…Both numerical evaluation and Monte Carlo simulations are performed using MATLAB. The default simulation parameter values are listed in Table I [2]. Besides, we futher analyse the performance of SCNs with different wall attenuations for various densities of BSs and walls.…”

“…It is expected that the mobile traffic demand will grow at an annual rate of 47 % by 2030, with about 80% of traffic demand generated indoors [1], [2]. The indoor wireless capacity can be tremendously improved by the deployment of small cells with high spatial spectrum reuse, which can implement the existing networks [3].…”

“…The indoor wireless capacity can be tremendously improved by the deployment of small cells with high spatial spectrum reuse, which can implement the existing networks [3]. The previous work on indoor wireless communication either ignored the effects of interior walls [2], [4] or focused on the line-of-sight (LOS) probabilities of indoor transmission links [5], [6] and wall reflection [7]. In this paper, we endeavour to analytically evaluate the coverage performance of indoor small-cell networks (SCNs) using stochastic geometry, considering the effects of interior walls, and shed new insights into practical deployment of indoor small cells.…”
