In this paper it is shown how a power line can be used to conductively carry and re-radiate 2.45GHz Wi-Fi signals over a distance. This can be useful when a conventional RF links' line-of-sight operation at 2.45GHz is obscured for example in multiple story buildings where Wi-Fi has difficulty penetrating. Commercial Wi-Fi modems were used to transfer data on a power line for up to 65m (non-energised)...
The metal halide lamp is a high energy electric lamp that produces visible light by an electric arc tube and it is a type of high-intensity discharge (HID) that contains a fused quartz and mixture of gases. These lamps inject noise into the smart-grid power line communications (PLC) network. This can have a strong and negative effect when using the PLC system to control the automatic switching of...
The mercury vapor lamp is the oldest high intensity discharge technology lamp that uses an electric arc, and comes in different shapes and designs. It creates a very bright light by using an arc through vaporized mercury in a high pressure tube. This lamp can cause unwanted interference to the smart-grid network or power line communications channel when connected to the channel’s wiring system. In...
