Making Gigabit Broadband a Reality with DOCSIS 3.1

Do you remember the old days when, to get the internet, you used a dial-up modem in your computer that used your home’s telephone wires? We’ve come a LONG way since then. When broadband delivered from a cable network provider became available in the early 2000’s the top speed you could get was only 1.5Mbps. By 2005 the peak rate was 8 Mbps. Two years later it doubled to 16 Mbps. But by 2012 the peak rate available to consumers in select cable markets was up to 305 Mbps. That’s a 900% increase in broadband speeds since 1999!  Intel’s Puma™ family of SoC’s have helped fuel these speed increases with our advanced cable modem technology for DOCSIS 3.0 networks.

But our work isn’t done. Although many PC’s, tablets, and phones connect to the internet today we expect even more devices in the home will get connected over the coming years. In fact, there are estimates that 50 BILLION devices will need to connect by 2020 – and fast networks will be necessary to support the massive increase in connections.

Enter DOCSIS 3.1, the next gen network specification that will deliver a massive speed increase for cable broadband deployments. A joint development by CableLabs and industry partners — including Intel, DOCSIS 3.1 will deliver up to 50% better throughput on channels and help service providers meet bandwidth growth for many years to come.

This week at SCTE’s Cable-Tec Expo in Denver, Intel’s latest DOCSIS 3.1 cable modem technology will be demonstrated interoperating with an Arris E6000 Converged Edge Router. Intel, as a co-founder of DOCSIS3.1, is working with all CMTS providers that are ready to test with our DOCSIS 3.1 implementation to make sure all critical ingredients are interoperable to accelerate DOCSIS 3.1 to a successful market deployment.

The live demonstration at SCTE showcases an FPGA implementation of our DOCSIS 3.1 platform for cable gateways featuring a complete OFDM downstream implementation. ARRIS’s E6000 generates the downstream OFDM transmission that feeds MaxLinear’s Analog Front-End (AFE). The AFE output feeds Intel’s OFDM demodulator implemented on FPGAs platform.

This downstream implementation emulates approximately 2Gbps data rates and can simulate various channel impairments in addition to displaying performance indicators such as SNR, carrier frequency offset, phase noise, and constellation diagrams.
