G.hn Ethernet-TV-WiFi Over Coax Access Network


G.hn technology supports up to 1.7Gbps Ethernet throughput over coax cable, making it an ideal solution for high-speed Ethernet or WiFi over coax access networks. Because coax cables are usually installed in all kinds of residential buildings, from rooftop/ground to individual rooms or apartments; a high-speed Ethernet network can be easily established by reusing the legacy coax cable.

Because G.hn uses OFDM technology, its frequency usage can be easily tuned to co-exist with TV (terrestrial/satellite/cable) signals. 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 existing TV or other signals over coax.

In addition, coax cable can also be used for reverse power feeding so that outdoor G.hn 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 rooftop or equipment cabinets. 

With today’s ever-increasing demand for WiFi coverage everywhere, coax cables 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 coax port in any room, and deliver reliable high-speed WiFi coverage throughout the house.

Xingtera chipsets have been selected for multiple G.hn Ethernet over coax devices and G.hn access network applications, and have been deployed around the globe.
