The wireless signal propagation in hybrid PLC-wireless channels: A first analysis

This work advances the study of indoor hybrid PLC-wireless channels when the frequency band delimited by 1.7 MHz and 100 MHz is taken into account. In this sense, a measurement campaign was carried out in a building facility to investigate the wireless signal propagation of these kind of channels. Based on the collected measures of PLC-wireless channels and additive noises, it is reported a agreement with previous works, in terms of average channel gain, power spectral density of additive noise and achievable data rates. Also, numerical results show that wireless signal propagation part of PLC-wireless channels can offer several hundreds of Mbps if a wireless device is located more than 6 meters from the power lines. Also, they show that PLC-wireless systems can be powerful tools to benefit wireless communication inside an office.
