G.hn Chipsets and Solutions

G.hn Standards

The G.hn (Ghn) chipsets and solutions are designed to comply with the ITU-T G.hn standards, the family of wired communication and home networking specifications developed under the International Telecommunication Union’s Standardization arm (ITU-T) and promoted by the HomeGrid Forum along with several other organizations. The G.hn specification defines ultra-high-speed networking over power lines, phone lines and coaxial cables with data rates up to 2,000Mbps. It is a complementary counterpart to WiFi technologies because G.hn provides a better way for Internet coverage throughout the house based on existing wires.

XT1000 Series G.hn Chipsets

Xingtera G.hn Chipset XT1800/XT128

The XT1000 Series (XT1800/XT1900/XT1910) chipsets are Xingtera’s G.hn (Ghn) based, high performance, carrier-grade chipset product line. The chipsets are fully compliant to the ITU-T G.hn standards, with support of multiple media including coax cables, power-lines, phone lines, twisted-pair cables, and other copper wires. The XT1000 series chipsets are capable of running ITU-T G.hn compliant 100MHz MIMO (XT1800/XT1900 over power-lines) and 200MHz SISO (XT1800/XT1910 over phone lines or coax cables) bandplans. The maximum PHY rate is 2Gbps, while the maximum throughput can reach 1.7Gbps.

The XT1000 series chipsets can be used to build various G.hn-enabled home networking or access networking products: power-line communication (PLC) adapters, Ethernet and WiFi extenders (over power-line, coax, or phone line), G.hn + Mesh WiFi devices, home gateways, set-top boxes (STB), home entertainment systems, network-attached storage devices (NAS), HDTVs, home security surveillance systems, digital signage, healthcare networking systems, gaming consoles, desktop PCs, etc.

G.hn Solutions

G.hn + WiFi Home Network SolutionG.hn PLC + Mesh WiFi Adapter

The combination of G.hn and WiFi technologies will enable full coverage of high-speed data networks via existing electrical wiring at home. G.hn can provide reliable Ethernet backhaul across multiple rooms, while WiFi can provide the best user experience using mobile devices. The traditional rate drop or instability caused by WiFi signal going through walls or ceilings can finally be resolved. 

G.hn Access Network Solution

G.hn over coax cables or phone lines can be used as the next-generation access network technology. With up to 2Gbps throughput and multi-node support, legacy wires such as existing phone wires, or residential coax TV cables can be re-used to deliver gigabit Internet data network, without interference with current phone or TV services. 

Video Surveillance Network Solution

For legacy analog video surveillance cameras, the major issue for upgrading to digital or IP surveillance camera is the installation of new wires (Ethernet cable or optical fiber). Using G.hn technology, the existing coax cable can be re-used for stable and high performance (up to 2Gbps) Ethernet network. In addition, the G.hn Ethernet over coax solution can support longer cable length (up to 2KM) and more nodes (up to 8) connected to a single coax cable, therefore enabling easy addition of more cameras based on the old wires.
