This process applies to a number of user kits (A, B, . . . X) and a head-end kit () communicating over the electricity network () using an upstream channel and a downstream channel. In essence, the process comprises accessing by multiple user kits (A, B, . . . X) in the upstream channel and the sending of multiple information frames by the head-end () in the downstream channel simultaneously applying OFDMA/TDMA/CDMA multiplexing and dynamically assigning each carrier so as to maximize transmission capacity in both the upstream and downstream channels. In turn, the process allows the adjustment of the quality of service according to the type of information and the user that requires the transmission and the dynamic allocation of bandwidth through constantly calculating the signal-to-noise ratio.

Process for multiple access and multiple transmission of data in a multi-user system for the point to multipoint digital transmission of data over the electricity network

The system enables bidirectional communication between a center and a plurality of users via a power line network and is characterized in that low and high speed communication can be established to provide multiple high-quality services to the users. The system comprises a performing network and frequency time-sharing and/or orthogonal frequency-division multiple access (OFDMA).
