TL;DR: In this paper, the authors focused on the characterization of Brazilian in-home power line channels for data communication when a sounding-based approach is applied based on a measurement campaign carried out in seven Brazilian residences, a statistical characterization of frequency response magnitude, average channel gain, coherence bandwidth, root mean squared delay spread and coherence time, achievable data rate, additive noise and access impedance are presented, considering the frequency bands from 17 up to 30, 50 and 100 MHz.

TL;DR: In this paper, a complete sounding-based methodology to estimate frequency responses of electric power grids combining sampling frequency offset error estimation and correction, timing synchronization, channel estimation, and channel estimation enhancement techniques is presented.

TL;DR: The characterization of indoor hybrid power line communication (PLC)-wireless channels in the frequency band between 1.7 and 100 MHz reveals that additivenoise power spectral density and channel capacity differ considerably in the PLC- to-wireless and wireless-to-PLC transmission directions.

TL;DR: The results obtained from numerical analyses offer important information about Brazilian outdoor and low-voltage electric power grids for data communication purposes and constitute an opportunity for increasing the knowledge about this kind of data communication media and for assisting the design of new generations of effective and reliable power line communication systems.

TL;DR: In this paper, a measurement setup that characterizes lowvoltage electric distribution grids as a medium for data communication when the frequency band is between 1.7 and 50 MHz is described.
