These days, it’s primarily touted as a solution to home networking problems. Instead, the MoCA standard was developed into a networking technology to carry Ethernet over coaxial cabling. That use case didn’t really eventuate, but the underlying technology was sound. MoCA stands for the Multimedia over Coax Alliance, and the technology was initially developed to send video over IP via existing coaxial cable runs. 1.0 edition equipment first became available in 2006. This wide base of installed coax led to the devleopment of MoCA, a network standard intended to use these cable runs. MoCA adapters, which hook up a typical RJ45 Ethernet connection to a coaxial cable. Other times, it’s simply because cable TV has been supplanted in some respects by the rise of streaming services. Sometimes, it’s because the transition to digital cable meant that a separate set-top box was needed per TV, adding expense. In this era, though, many coaxial outlets are going unused. Today, they’re often still in use, delivering cable TV and cable internet services. Thus, in the United States, there are a huge number of buildings with coaxial cables sitting in the walls. Individual homes would often have coaxial cable routed throughout to provide for multiple TVs in lounge rooms and bedrooms throughout. Apartments and hotels would often have a distribution box with cable “drops” heading to each individual dwelling in the building. These cables worked their way around the neighbourhoods of the nation, often being split or tapped to deliver cable TV services to yet more subscribers. In those hallowed days, cable television was delivered as analog signals sent via coaxial cable runs. Just 6.4% of Americans had cable TV by 1968, but that figure reached a full 62.4% by 1994.

Run What You Brung MoCA hardware can be used to create networks on traditional cable TV infrastructure, such as that often laid in apartment buildings and hotels. It’s only if you go back to the very dawn of Ethernet that coaxial cables are relevant… right? Wrong! MoCA networking is all about coaxial cables, designed to hook up devices over cable TV infrastructure! Beyond that, we’re all familiar with the Cat 5 and Cat 6 cables that form the high-capacity Ethernet networks in our homes, schools, and offices. When it comes to networking these days, the vast majority of our devices are connected wirelessly.
