multimedia over coax alliance (MoCA)

The Multimedia over Coax Alliance (MoCA) is concerned with home networking based on coaxial cables. As an association with well-known manufacturing companies, MoCA has developed a standard of the same name for data transmission on the physical layer.

The first version of the MoCA standard, MoCA 1.0, dates from 2006 and had a data throughput of 100 Mbps. In the following years, MoCA 1.1 with 175 Mbit/s and MoCA 2.0 (2010) with 500 Mbit/s and 1 Gbit/s with line bonding were developed. The latter version was further developed and equipped with a number of security functions and routing features. With MoCA 2.5, which can bundle up to five channels, a data throughput of 2.5 Gbit/s is achieved.

MoCA networks are IP networks in which MoCA-compatible devices are networked together. One device forms the master station and up to 16 operate as slaves. The MoCA devices are connected via a control channel, and there are payload channels for the payload data. MoCA uses Orthogonal Frequency Division Multiplex( OFDM) as the transmission technology. Cable distribution networks and broadband cable networks serve as the transmission infrastructure.
