The ITU-T G.hn standard provides high-speed (up to 1 Gigabit/s) local area networking over existing home wires, including coaxial cable, power lines and phone lines. It defines an Application Protocol Convergence (APC) layer for encapsulation standard 802.3 Ethernet frames into G.hn MAC Service Data Units (MSDUs).
This scenario becomes very common as service providers start to offer service packages with multiple set-top boxes per subscriber. G.hn can connect the residential gateway to one or more set-top boxes, by using the existing home wiring. Using G.hn, IPTV service providers do not need to install new Ethernet wires, or 802.11 wireless networks ...
Different types of network cables, such as coaxial cable, optical fiber cable, and twisted pair cables, are used depending on the network's topology, protocol, and size. The devices can be separated by a few meters (e.g. via Ethernet ) or nearly unlimited distances (e.g. via the interconnections of the Internet ).
DVB-C2, an enhanced version of the DVB-C digital cable TV standard; Power line communication (PLC) ITU-T G.hn, a standard which provides high-speed local area networking of existing home wiring (power lines, phone lines and coaxial cables) [13] TrailBlazer telephone line modems; Multimedia over Coax Alliance (MoCA) home networking; DOCSIS 3.1 ...
One example is the ITU-T G.hn standard, which provides a way to create a local area network up to 1 Gigabit/s (which is considered high-speed as of 2014) using existing home business and home wiring (including power lines, but also phone lines and coaxial cables).
Point-to-point Ethernet links are carried over SDH/SONET networks, making use of virtual concatenation (ITU-T G.707) and LCAS (Link Capacity Adjustment Scheme - ITU-T G.7042) to create an appropriate size carrier bundle, of the Generic Framing Procedure of SDH equipment, and takes advantage of the management and recovery features of SDH to ...
NIST has included ITU-T G.hn as one of the "Standards Identified for Implementation" for the Smart Grid "for which it believed there was strong stakeholder consensus". [131] G.hn is standard for high-speed communications over power lines, phone lines and coaxial cables.
ITU-T G.hn technology uses existing home wiring (coaxial cable, phone lines and power lines) to create a high-speed (up to 1 Gigabit/s) local area network. Signal traces on printed circuit boards are common for board-level serial communication, particularly between certain types integrated circuits, a common example being SPI.
