Hybrid Power Line/Wireless Systems: Analyses of Normalized SNRs for In-home Broadband Scenarios

This paper analyzes the normalized signal-to-noise ratios (nSNRs) of power line and wireless media to evaluate the suitability of hybrid power line/wireless systems in in-home broadband scenarios. In this sense, we assume that the transmitter node knows the channel state information, and then we seek to find the level of diversity between power line and wireless medium based on the amount of nSNR intersections in the frequency domain. In the numerical analysis, we show that power line and wireless media present nSNRs intersections in several scenarios. Moreover, we verify that greater diversity is found with the distance increasing, which favors hybrid power line/wireless systems.
