Summary

Recommendation ITU-T G.9963 specifies the basic characteristics of a multiple-input multiple‑output (MIMO) high-speed home networking transceiver capable of operating over premises power-line wiring. This Recommendation includes the additions and modifications to Recommendations ITU-T G.9960 and ITU-T G.9961 that are required in order to fully define a MIMO home networking transceiver. MIMO transceivers are able to transmit over three power-line conductors (phase, neutral, and ground) in more than one Tx port and receive in more than one Rx port, thus providing an increased data rate and enhancing the connectivity (i.e., service coverage) of the home network. This Recommendation also specifies the means by which transceivers that comply with ITU-T G.9960, ITU‑T G.9961 and ITU-T G.9963 interoperate when operating on the same wires.
