Lantiq announces G.hn chips
Lantiq introduced a chip family supporting the recently ratified G.hn (gigabit home networking) standard for wired home networks.
G.hn defines standards for home networks that could combine communications over a mix of wires, including phone, power and coaxial cable. Depending on which method or methods are used (and of course on network conditions), throughput rates could be as high as 1 gigabit per second (Gbps).
Lantiq XWAY HNX chips can be used in standalone G.hn node applications or as part of multi-service platforms. The device is provided to customers with a software package that includes pre-integrated drivers for the broad range of Lantiq system-level silicon devices, including Gigabit speed gateway processors, 802.11n WLAN supporting carrier-grade video, DECT/CAT-iq, VoIP and analog voice.
"In Lantiq's vision for connectivity in the digital home, we see standards-based wireline and wireless technologies working as one single network to provide the best possible quality of service, reach and flexibility throughout a household," said Christian Wolff, CEO of Lantiq. "From day one, we are delivering G.hn solutions that will integrate seamlessly in a hybrid network infrastructure. The XWAY HNX family also includes Lantiq-exclusive technologies for optimal QoS and overall in-home network performance."
Lantiq has designed its chips with the ability to support what it's calling carrier-grade QoS over Anything (including G.hn, Wi-Fi, Ethernet, DSL and PON). It allows service providers to pick and choose which services and applications receive the highest priority inside both access and home networks.
Spectrum management technology maximizes performance of VDSL and G.hn networks operating side by side. Probe technology delivers real-time diagnostic information about subscribers' home networks, letting service providers optimize performance even in complex subscriber environments. Lantiq's chips also perform automatic path selection across the home network, using real-time link quality information to choose the optimal communication path (802.11n, wired Ethernet, G.hn, etc.); this dynamically avoids line noise.
Companies can start ordering evaluation kits at the end of this month. The company expects to ramp up to production volumes sometime in the second quarter.
Sigma Designs announced a G.hn chip in October. Several other manufacturers are expected to announce similar chips in the coming months.
U.S. service providers are said to be keeping an eye on the technology, but the most enthusiasm for G.hn so far has been found overseas. China Telecom, for instance, has expressed interest.
Tom Starr, the chairman of the ITU-T WP1/15 committee responsible for the G.hn standards, said: "I am pleased to hear that products based on the G.9960/9961
ITU-T Recommendations will be available from Lantiq and other vendors so quickly after the approval of these standards. This will accelerate the adoption of G.hn as the next-generation standard for wired home networks."
