In the indoor environment of multiple-story buildings, the line-of-sight (LOS) radio frequency (RF) signal is generally obstructed by walls and slabs. As a solution to this dilemma, power line communication (PLC) is an alternative to overcome the LOS RF penetration issue. PLC is a cost-effective system that uses an alternative technology approach, through the help of already existing electrical distribution network in-side the building, to transmit data. In this approach, the electrical wire acts as a radiating antenna which takes through the RF signal. Firstly, the signal is detected and demodulated by an RF receiver, which becomes mobile due to the contactless aspect of the link. The focus of this paper is to analyze the performance of such a system and propose measurement results. The overall concatenation of PLC and RF systems. Simulation results exhibit the channel frequency response of the cascaded PLC-RF and its performance is measured through practical implementation.

在多层建筑物的室内环境中，视线（LOS）射频（RF）信号通常会被墙壁和楼板遮挡。作为解决这一难题的方法，电力线通信（PLC）是克服LOS RF穿透问题的替代方法。PLC是一种经济高效的系统，它使用替代技术方法，通过建筑物内部已经存在的配电网络的帮助来传输数据。在这种方法中，电线充当吸收射频信号的辐射天线。首先，信号由RF接收器检测和解调，由于链路的非接触方式，该信号变得可移动。本文的重点是分析这种系统的性能并提出测量结果。PLC和RF系统的整体串联。
