Statistical analysis of Brazilian in-home PLC channels: First results

This contribution outlines a statistical characterization of Brazilian in-home and low-voltage electric energy distribution networks as a data communication medium. The discussions are based on estimated channels obtained in a measurement campaign carried out in several apartments whose size ranges from 50 up to 90 square meters. The parameters considered for this analysis is the root-mean square delay spread (RMS-DS), the average channel gain, and the channel capacity. For the sake of comparison with electric networks in US, the frequency band ranging from 1.705 up to 30 MHz was set. The reported analysis shows that the RMS-DS can be modeled as a log-normal variable in only 33.33% of the cases and the average channel gain does not follow a log-normal distribution, the average channel gain is lower in Brazil than in US and the inter-symbol interference is quite similar in both US and Brazil.
