Heat's on for Moca, too

The folks at the Multimedia over Coax conference were mum on their road map this week except to say that they have kicked off a MoCA 2.0 effort. Their customer base, however, was somewhat more vocal.

"The next-generation MoCA spec needs to support about 400 Mbits/s within two years and a Gbit in four years," said Mark Wegleitner, chief technology officer of Verizon Communications in a keynote speech. Verizon is installing fibre-to-the-home systems that can hit up to 400 Mbits/s today, and it can't let the current 175 Mbit/s MoCA 1.1 technology be a bottleneck for long.

Jed Johnson (right), senior director of systems engineering at Motorola which supplies set-top boxes to Verizon, echoed the call for more bandwidth. "There needs to be a gigabit path in the home," said Johnson.

What with startup Gigle Semi and the ITU g.hn standard in the works potentially delivering a Gbit/s PHY next year, MoCA has some pretty clear marching orders.
