The lab test itself was the result of several weeks of construction, preparation and design by Comcast network engineers in Philadelphia and Denver.”

“ played a key role, along with industry partners, in developing the DOCSIS 4.0 Full Duplex standard. “Comcast has been working to develop the technologies that power 10G since well before it was formally introduced in January 2019,” he said.

In my area, I can pay for a gigabit downstream connection. Last October, Comcast technologists were able to deliver 1.25 gig symmetrical speeds over a live, all-digital network by leveraging advances in Distributed Access Architecture, Remote PHY digital nodes, and a cloud-based virtualized cable modem termination system platform (vCMTS).Įven as Comcast works to test and deploy Full Duplex DOCSIS to enable multigigabit upload and download speeds in the future, the company is leveraging the technologies from the October trial, along with DOCSIS 3.1 in the upstream, to increase speed and capacity in the near term. “More broadly speaking, the developments we’re seeing today on 10G are the result of global collaboration between operators, technology makers and standards bodies,” Nafshi said. He said the SoC was built by Broadcom, and the test was designed and executed by Comcast network engineers in Philadelphia and Denver, with the support of technology partners at Broadcom. Comcast’s visionĮlad Nafshi, the senior vice president of next generation access networks at Comcast Cable, said in an email to GamesBeat that the performance of the Broadcom chip exceeded expectations. Future optimization is expected to drive even greater capacity. In the test environment, the research team demonstrated the ability of the system-on-chip (SoC) to deliver upstream and downstream throughputs of greater than 4 gigabits per second (Gbps). One of the most important breakthroughs in the DOCSIS 4.0 standard is the ability to use network spectrum more efficiently, allowing operators to dramatically increase upstream speeds without sacrificing downstream spectrum to do so, Comcast said.Ī key advantage of DOCSIS 4.0 Full Duplex is that it establishes a foundation for operators to deliver multigigabit speeds over their existing networks to the connections already in hundreds of millions of homes around the world, without the need for massive digging and construction projects.Ĭomcast technologists in Philadelphia and Denver conducted the test by installing the Broadcom SOC in a simulated network environment to track the performance of its Full Duplex DOCSIS features (including echo cancellation and overlapping spectrum) that combine to support substantial improvements in network throughput. The Broadcom chip is expected to become the world’s first production silicon to be developed using the DOCSIS 4.0 Full Duplex standard, which represents an evolutionary leap forward in the ability to deliver ultra-fast speeds over HFC networks.

Makes no sense to me.This trial begins to lay the groundwork for network operators like Comcast to deliver multigigabit download and upload speeds over connections that are already installed in hundreds of millions of homes worldwide. They keep trying to tell me that my speeds will change depending on who’s online in the area but when I had the slower speed I never had anything until 400mbps and now there are times I’m not even hitting that with 1200mbps plan. I hate paying for something that I’m not getting. Do I need to purchase my own modem? I am lost. So my question is has any dealt with this issue? Do I need to run a new Ethernet cable to handle the speeds? MB says it handles speeds 1000mbps.

However, when I do these speed tests on my phone I am getting 600-700mbps download speeds on Wi-Fi which makes no sense to me. All these speeds I’ve tested have been through an Ethernet cable to my PC. It’s been 48 hours and I’m still only getting 300-500mbps download. He went to the truck and gave me a new modem and said give it 24 hours and you should be seeing your speeds. They sent a tech to my house and the tech said all the cable on the outside of the house was golden and that I had a bad modem. Issue is every since they upgraded me I’ve been getting speeds of 300-500mbps downloads but I’m getting 30-40mbps upload. I upgraded recently to their 1200mbps download and 35mbps upload for streaming purposes and the price I got it at.

I have Comcast internet and I was originally paying for 400mbps download and 10mbps upload and was getting speeds in the ballpark of 400-500mbps. I am hoping that someone here can help me as Comcast can’t seem to.
