This paper presents the factors such as load impedance,
line length and branches (distributed and concentrated) on
the performance of a low voltage broadband power line
communication (BPLC) channel. Emphasis is given to the
power line networks that are used in Tanzania. Different
investigation with regard to network load impedances,
direct line length (from transmitter to receiver), branched
line length and number of branches have been carried out.
From the frequency response of the transfer function
(ratio of the received and transmitted signal), it is seen
that the position of notches and peaks in the magnitude
are largely affected by the above said network
configuration, which are observed in the time domain
responses too. The observations presented in the paper
could be helpful in suitable design of the PLC systems for
a better data transfer and system performance.
