Think your cable connection's fast? Arris thinks it could be a lot faster. At today's NCTA Cable Show in Chicago, the company will demo a new system that can support download speeds of 4.5Gbps, and upload rates of 575Mbps. To achieve this, Arris devoted more of its DOCSIS 3.0 cable channels to broadband (128 downstream, 24 upstream), sourced through a C4 cable module (pictured on the left). Of course, this would leave less space for conventional TV channels, but we're guessing the accelerated streaming speeds would more than make up for it. Unfortunately, the prototype is still in the proof-of-concept phase, so it may be a while before you reap its benefits. Head past the break for the full PR.
