Abstract
To design and construct future wireless-friendly buildings, the wireless-friendliness of buildings, i.e., building wireless performance (BWP), must be evaluated to provide quantitative guidance for future building design. However, the BWP evaluation approach for indoor device-to-device (D2D) networks, which are expected to be widely employed, is absent from the existing theoretical systems of BWP evaluation. Accordingly, this paper presents the first systematic BWP evaluation approach for indoor D2D networks. We create a BWP evaluation metric, blockage gain, by simultaneously considering the impacts of building layouts and building materials. The blockage gain is defined as the spatially averaged coverage probability (SACP) improvement due to the out-of-room interference blockage by the room walls. We derive the theoretical upper and lower bounds of the SACP in the general scenario, and we obtain the empirical formulas of the SACP and the blockage gain by the derived upper and lower bounds. The empirical formulas indicate that the impacts of building layouts and building materials can be decoupled. Moreover, the results show that well-designed rooms can improve the SACP of the indoor D2D network by at least 0.1. This work can provide guidance for architects to design wireless-friendly buildings for indoor D2D networks.
