I'm excited about the upcoming symmetrical gig service. https://www.dslreports.com/shownews/Your...ove-141155
Approval from the regulatory authority doesn't guarantee immediate implementation. It will need extra radio frequency spectrum to handle more channels, plus a complete overhaul of existing cable infrastructure to add nodes that support these new channels. The return signal will also have to be sent back to the central monitoring system.
Will this cost less than fiber deployment? In a COX area with ongoing fiber projects and a potential N+O setup, it might be more economical.
In the long term, it’s likely the setup is mostly ready. It mainly depends on whether they use a CMTS that supports Docsis 3.1—typically the Cisco cBR-8 or Arris E6000 models. The biggest adjustments will probably occur at the node level to accommodate the increased bandwidth, frequency shifts, and channel width changes.
We're primarily discussing swapping out amplifiers for various return frequencies, not other gear. My background is mainly in single-building coax systems, while neighborhood-wide setups fall beyond that scope.
The problem is that cable companies are currently using 5 MHz to 42 MHz for upstream speeds. They're working hard to expand the available spectrum for higher speeds, but it won't happen soon. Comcast was an early adopter of DOCSIS 3.1 and still only manages about 35 Mbps uploads. I think it'll take a few more years before this improves. Still, it's interesting tech—it could help cable compete with fiber, mainly because latency might be slightly higher for cable.
