Power line
communications (PLC) is a known low cost technology which is easily installed
and extended to the various connections especially to areas with poor wireless
coverage. Unfortunately, designers and users experience technical problems that
arise from the difficulty of operating on a complex time varying medium and
that limits the expected high throughput. Therefore, testing and understanding
network dynamics of PLC systems before usage is a necessity. This paper
presents the findings obtained from the experiments carried out in order to
verify the throughput performance of PLC systems. Experimental measurements are
realized in different testbeds, under different times and conditions, in order
to achieve an idea of the practical PLC performance. Data obtained from the
measurements have been stored and the throughput is analyzed by the help of
software. Following, using distribution fitting methods, it is shown that the
PLC throughput may be modeled by the extreme value distribution. Furthermore,
adding a basic noise to the network, simply by lamps, results with a degraded
performance. The noise changes the parameters of the derived distributions; a
decrease in expected value and an increase in standard deviation are observed.
