Abstract-The aim of this paper is to propose and evaluate a semiempirical propagation modeling for radiating cable used in indoor environments. This propagation modeling takes into consideration propagation mechanisms such as reflections, penetration loss and cable termination that result from a particular environment, as well as specific cable paths that actual propagation models for radiating cable systems have not considered. The proposed modeling is carried out using three different propagation models and has been experimentally validated by sets of measurements performed in a university building in the frequency range from 900 MHz to 2.5 GHz. A careful selection of the data sets validates the robustness of the proposed model. The results show a mean of the error less than 1 dB while the standard deviation is between 2.2 dB and 4.6 dB in all cases. To the best of our knowledge, this is the first time such a robust modeling for radiating cable operating between 900 MHz to 2.5 GHz has been presented.

In this work, an alternative technology to extend wireless coverage beyond the conventional methods of providing radio propagation coverage is presented. The use of a radiating cable is proposed for difficult-to-reach areas. In this regard, an indoor radiating cable is successfully employed for the distribution of an analog electric signal in a fiber-radio scheme using a microwave photonic filter. A filtered microwave band-pass window located at 2.24 GHz is used as an electrical carrier to transmit an analog TV-signal of 67.25 MHz over an optical link of 25.28 km. Measurements are carried out in an indoor environment. Experimental results demonstrate that the recovered signal is of good quality in each measurement location, exhibiting on average a signal-to-noise-ratio (SNR) of around 31.60 dB.
