It is also compatible with DOCSIS 3.1.

Complete Duplex technology has been in the limelight since CableLabs declared in February that it would analyze the ins and outs of spectrum sharing as part of an “initiation stage” research project.

Nokia is not working with CableLabs but according to David Eckard, CTO of fixed networks, the firm has participated with several Tier 1 operators in Europe and both North America to investigate the chances around deploying Complete Duplex technology in the future. Eckard admits it won’t difficult.

“This Complete Duplex operation is incredibly challenging, with challenges both in the analog domain as well as in the digital,” says Eckard.

On the other hand, the theory is much the same to one that Nokia has introduced with DSL in copper network surroundings. And significantly, Nokia can bring its expertise into the cable land in echo cancellation and in interference direction from the DSL world.

Nokia is not the only firm putting wagers on Full Duplex.

Joel Brand, vice president of product management at Kumu Networks, additionally has an excellent method of describing in layman’s terms Full Duplex works.

You’ve got a device that sits between your mouth and your ear,” Brand described in a recent interview, “and when you talk, that apparatus uses precisely the same rule of the noise cancelling headset, and it deletes the sound which you’re talking such that you do not hear what you are saying. Should youn’t hear what you are saying, you can listen better to everything that comes from the surroundings.”

That is how Total Duplex enables both upstream and downstream traffic to inhabit precisely the same frequency bands at precisely the same time.

In Nokia’s case, the business can show that Full Duplex works over coaxial cable, but it is just reached symmetrical 10-Gigabyte speeds in a scenario where fiber is shoved all the way to the pat, and after that coax links the last 100 meters to just one endpoint.

In addition to software development and additional hardware and standardization work, operators will need to drive fiber into their networks in order for Full Duplex to be practical.

“This will be coupled to deep fiber and likely be coupled to some sort of distributed access structure also,” says Eckard.
