Smart cities and smart buildings must provide their customers with many services, including those associated with health, productivity, and energy efficiency, among others. Short-range wireless systems can provide all of these services, but the significant growth of wireless networks operating within a smart building (SB) can produce the phenomenon of spectrum shortages. Spectrum shortages could be resolved using Cognitive Radio (CR)-based systems to improve the efficiency of electromagnetic spectrum use by taking advantage of the reusable spectrum available in the building’s interior. This study proposes a mechanism using two interference conditions to quickly estimate the minimum amount of effective spectrum availability (ESA) inside an SB. The results show that an SB contains ESA distributed across 36% to 98% of the building’s area for reuse, as a function of the height of the building and of the distance from the base station (BS) of the primary system.

估算智能建筑内部有效频谱可用性的机制
智慧城市和智慧建筑必须为客户提供许多服务,包括与健康,生产力和能源效率相关的服务。短距离无线系统可以提供所有这些服务,但是在智能建筑(SB)中运行的无线网络的显着增长会产生频谱短缺的现象。频谱短缺可以使用基于认知无线电(CR)的系统来解决,以通过利用建筑物内部可用的可重复使用频谱来提高电磁频谱的使用效率。这项研究提出了一种机制,该机制使用两个干扰条件来快速估算SB内部有效频谱可用性(ESA)的最小数量。结果表明,SB包含ESA,该ESA分布在建筑物面积的36%到98%之间以供重复使用,
