Altamira-bison-180So cheap, all of cable will go DOCSIS 3.1. DOCSIS 3.1 is designed to do a gig up and down, but only the downstream is widely deployed. Gig downstream cable is deploying rapidly, with Comcast and Cox expecting to cover 50% of the U.S. in the next 24 months. Until now, cable upstream doesn't match fiber or G.fast, running 20-35 meg at best. Upstream DOCSIS 3.1 is not yet deployed anywhere, although Comcast has announced they will begin in 2017. Others will wait for full duplex. Vodafone in Spain now has promised a gig across their entire network by the end of 2018, including upstream.

Until now, cable upstream doesn't match fiber or G.fast, running 20-35 meg at best. Upstream DOCSIS 3.1 is not yet deployed anywhere, although Comcast has announced they will begin in 2017. Others will wait for full duplex. Vodafone in Spain now has promised a gig across their entire network by the end of 2018, including upstream. I wouldn't be surprised if the pr is running ahead of the likely deployment and that the upstream is a little later.

Vodafone Spain is built around the former ONO, purchased by Voda in 2014 for €7.2 billion. It has 2.1M cable customers while passing 9.5M.

The $50/customer cost is based on the $100M Huawei deal/2M; it also covers the homes who haven't connected, effectively lowering the cost. Note that the new modem is not included.

Early in the history of DOCSIS 3.0, Mike Fries of Liberty Global told the Times the upgrade cost was $20/home, even less than I had heard. (Plus new modem) The low cost made it easy to predict all the major cablecos would move quickly to 3.0. They did.

Downstream was available before upstream. We're seeing that in 3.1 as well, with just about every cableco in the U.S. and Europe moving ahead.

I think LGI's cost was particularly low because Balin Nair had the foresight to plan ahead in his earlier capital spending and that others spent somewhat more. I suspect similar is true today; other cablecos face a higher or lower cost. But nearly all cablecos will soon upgrade at least to 3.1 downstream.

Some cablecos intend to wait for the full duplex technology being defined at CableLabs. That uses intense noise cancellation that allows using the same spectrum for upstream and down. That's potentially even faster: DOCSIS 3.1 is defined up to 5-10 gigabits, although nowhere deployed at more than 1 gig to the customer. Full duplex works in the labs on wireless and DSL; Kumu Networks is doing wireless field trials with Telecom Italia and hinting they are close to a major announcement. 

 

Vodafone Spain will update its HFC Network and offer customers symmetrical speeds of more than 1GBPS

Change network architecture and deployment of Docsis 3.1

  • Vodafone Spain has awarded the update of its network to Huawei.
Madrid, January 9, 2017.- Vodafone Spain announces the update of its HFC network to offer its customers -misma symmetrical speeds and upload speeds greater than 1 Gbps bajada-. The solution adopted goes beyond simply updating the network to DOCSIS 3.1, as it involves a new architecture based on the deployment of extension points of the fiber network and the increase of available bandwidth for each Client. 
The network upgrade brings to Vodafone's customers a faster data service, as well as the possibility of adding new channels to Vodafone TV including all 4K capacity. 
This design offers the following advantages:
  • Higher speed: thanks to the increase of the available spectrum and the change of modulation, the bandwidth increases per Client.     
  • Improved operational and network quality
  • More flexibility and greater scalability: today's announcement opens up new possibilities for deployment, since from the same "fiber network extension point" you can choose to offer access to new Real Estate Units through HFC or FTTH technology The Home).
With the implementation of DOCSIS 3.1, Customers will be able to enjoy symmetrical speeds greater than 1 Gbps. The current technological standard will allow for download speeds of up to 10 Gbps and the industry continues to work on the evolution of DOCSIS to raise the speed of data upload in the network and respond to the demand that may arise in the future from applications intensive in The consumption of data. 
The update of the network has already begun in the main cities and will be extended to the whole territory during the next 24 months.
