The G.now™ Broadband Network Access System

G.now™ is a gigabit network access solution based on G.hn standards. It enables data rates up to 1Gbit/s over legacy bundled copper lines (twisted pair phone lines). Utilizing an FTTdp network architecture, it allows for near FTTH performance on existing infrastructure, and offers unrivaled value to network operators, their clients and end users.

G.now™ is a trademark of Marvell Inc, a global leader in integrated silicon solutions. Marvell’s G.now is an extension of the G.hn networking standard, enabling broadband access. It enlarges the scope of the ITU-T G.hn standard to bridge the performance gap between currently available VDSL2 and fiber to the home technologies.

G.now™ technology is based on Marvell’s award-winning HomeGrid Forum-certified family of G.hn chipsets, providing FTTH class broadband access to multi-dwelling unit (MDU) buildings over existing phone lines.  G.now™ technology can quickly offer many homes and consumers around the world access to seamless delivery of high quality content from the cloud, fitting nicely with the bandwidth demands of the ‘Always Online, Smart Lifestyle’. G.now™ brings consumers one step closer to the Gigabit revolution through its ability to deliver a high performance, reliable and secure end-to-end solution.

Based on TDD architecture (Time Division Duplexing) and an increased spectrum up to 100 MHz OFDM, Marvell G.now™ turns G.hn into a technology that by far outperforms VDSL2. It enables unmatched connectivity at up to 1 Gbit/s PHY rate over existing copper wiring and a far higher data rate (over 500Mbps) than legacy VDSL systems (only 100 Mbps).

It is our mission to work closely together with our partners, including global operators, service providers, internet companies, OEMs, ODMs and other ecosystem partners to ensure that G.now™ technology brings the benefits of true broadband access to consumers around the world.
