DOCSIS

In our recently published blog post, we demonstrated why indoor femtocells have reemerged as an attractive deployment model. In particular, indoor network densification has huge potential for converged cable/wireless operators who can leverage their existing Hybrid Fiber Coax (HFC) footprint to either backhaul from full-stack femtocells or fronthaul from virtual Radio Access Network (vRAN) remote […]

An industry colleague recently reached out to a few of us with a problem: A cable operator was having trouble with a cable modem termination system (CMTS) in his network. The manufacturer of that CMTS had claimed that it was “DOCSIS® Compliant,” and therefore this operator apparently had assumed it would just work. We checked […]

As the small cell densification wave is becoming a reality, mobile operators are faced with the complex task of searching for suitable backhaul solutions. This is where the hybrid fiber coaxial (HFC) networks rise up to the challenge. DOCSIS networks provide three main elements critical to backhaul solutions; location, power and capacity. Mobile operators are […]

With 5G and small cell densification on the near horizon, mobile networks need economically viable backhaul solutions. Cable operators are well positioned with fixed networks to bridge that gap, and many operate mobile networks themselves. Could we be on the verge of fixed-mobile network convergence? Things seem to be pointing in that direction, but it […]

The wireless ecosystem is a rapidly moving marketplace, and the next milestone is the large-scale deployment of small cells to augment network capacities and to support 5G deployments. There are three main elements required to deploy small cells: Location Power Backhaul These requirements put cable operators, many of whom are also mobile operators, in an […]

The demand for data network capacity has been growing exponentially year after year with no sign of stopping. If the past is a guide to the future, the cable industry must come up with radically more efficient use of the existing cable infrastructure in order to meet demand. Today, the most constrained part of the network, and the […]

October was Cybersecurity Awareness Month in the US. We certainly were aware. In September, IoT cameras were hacked and used to create the largest denial of service attacks to date, well over 600Gbps. On October 21, the same devices were used in a modified attack against Dyn authoritative DNS services resulting in disruption of around […]

“I don’t want to have to share a pipe. The problem with ‘cable’ is shared pipes. If my neighbor is doing a bunch of stuff over the network, I get impacted too. With fiber I get speed and no shared pipes.” — Entrepreneur in a focus group The notion that subscribers connected to residential fiber […]

Security engineering is one of few technical endeavors in which you deal with an adversary. There are a few other domains such as electronic warfare or fire prevention. Working against an adversary in this way is like playing a twisted game of chess. As the game begins, the security engineer is aware of most of […]
