Abstract—The emerging smart grid system requires high speed
sensing of data from all the sensors on the system within a few
power-cycles. The Advanced Metering Infrastructure is a simple
example of such a system where all the meters on a certain grid
must be able to provide the necessary information to the master
head end within a very short duration (fraction of a second for
real time load control). Wireless solutions for the smart grid
systems have been implemented, but cannot access all grid
locations, especially enclosed ones. In this paper, we present an
interactive, OFDMA based communication system optimized for
operation over the low voltage power lines in the CENELEC
bands A and B. A channel model representing statistical timevarying,
and frequency selective powergrid channels and noise is
presented. Using this model, an OFDMA based transceiver is
developed that is capable of providing smart grid like access
capacity to the head end connected to multiple meters. The
transceiver is optimized based on the channel model and the
characteristics derived from the structure of the grid.
