G.hn-Chip for Home Networking

G.hn-Chip for Home Networking

The network developer Marvell has introduced a chipset consisting of Baseband / MAC chip (88LX3142) and Analog-Frontend/Transceiver (88LX2718, PHY), which corresponds to the ITU standard G.hn and data over electrical wires, coaxial or twisted pair cable, with up to 1 Gbit / s transport is gross. According to the Marvell chipset, especially for simple networking of TV sets, Medienabspielern and networked storage devices with Ethernet interfaces is suitable. He should get hold of competing technologies such as HomePlug AV or Moca shares in the lucrative home networking market.


At the rate surpassed, according to the Marvell chipset G.hn all other techniques.

Marvell to heise networks As explained, the transceiver G.hn achieved with sparing of the frequencies of short wave amateur radio and FM broadcasting in the range 2-80 MHz up to 800 Mbit / s gross. At present, current HomePlug AV-compatible Powerline adapters provide up to 500 Mbit / s gross for good connections. Are not compatible, the two systems, but at least coexists with Marvell chipset older powerline adapters.

The 88LX3142 prioritizes video traffic via QoS with 8 priority levels. G.hn adapter can be linked to as usual with HomePlug AV push of a button and provided with individual keys. Furthermore, the device can be via a web server and a "Multi-Platform Configuration Tool" set, available for remote configuration and TR-069 TR-111 ready. TR-111 is an extension of TR-069 to manage devices behind NAT gateways.
