G.hn Ethernet over Phone-Line Home and Access Network


G.hn technology supports up to 1.7Gbps Ethernet throughput over phone-lines (phonelines), making it an ideal solution for high-speed home or access networking applications over existing phone-lines or twisted-pair cables. Because phone-lines are usually installed in most residential buildings, connecting from a switching device to individual rooms or apartments; a high-speed Ethernet network can be easily established by reusing the legacy phone-lines.

Because G.hn uses OFDM technology, its frequency usage can be easily tuned to co-exist with telephone (POTS) signals, as well as other data communication signals such as ADSL/VDSL/HomePNA. By default, Xingtera’s G.hn chipset supports 0-200MHz or 100-250MHz frequency range. However, the firmware supports quick configuration to adjust the groups of subcarriers in any field applications. It is even possible to mask out multiple groups or frequency bands so that the G.hn data signal does not interfere with certain high-frequency signals.

In addition, phone-lines can also be used for reverse power feeding so that outdoor phone-line units do not require a standalone power supply, further simplifying deployments. This feature is very important for access network installation because sometimes it is quite difficult to find power supply in equipment cabinets. 

With today’s ever-increasing demand for WiFi coverage everywhere, phone-lines can be utilized to extend WiFi signals to different rooms even floors. Xingtera’s G.hn chipset can be easily integrated with WiFi chipsets to create a G.hn+WiFi device, which can be plugged into any RJ-11 jack in any room, and deliver reliable high-speed WiFi coverage throughout the house.

Xingtera chipsets have been selected for multiple G.hn Ethernet over phone-line devices for home networking applications, and have been deployed around the globe.
