Abstract
This paper shows how Light Emitting Diode (LED)
Tubes negatively influence the data rate throughput of an indoor
broadband Power Line Communications (PLC) channel. This
negative influence on the data rate is due to noise being generated
by the lamps. Differential Mode measurements were done with
two PLC modems communicating and then introducing LED
lamps that add noise to the channel. Drops in data throughput
rates were measured and compared to a clean (no noise) channel.
A significant decrease (up to 50%) in throughput was observed
which can have important implications for applications of PLC in
the presence of LED Tubes.
