MoCA 1.1 was released in 2007, bumping speeds to 175 Mbit/s and adding capability to handle 16 nodes. The first 1.0 version of the standard allowed for half-duplex operation at up to 100 Mbit/s, and could handle up to eight nodes. Special filters are often also used to prevent MoCA signals from reaching other cable network users beyond the dwelling or building intended. In the case of DOCSIS internet though, special measures had to be taken to make the standards interoperable. MoCA achieves this by simply running on frequencies not traditonally used by cable TV. MoCA networking had to be able to run on coaxial cables that may still be in use for cable TV or cable internet delivery.įunctionally, this meant that MoCA signals had to avoid stepping on cable TV bandwidth, or interfering with DOCSIS cable internet signals. However, MoCA differs, as it was developed for a different use case. Back then, the various standards for coax ethernet were colloquially known as thicknet and thinnet depending on the diameter of coaxial cable used. The MoCA concept may sound curious, given that Ethernet was originally carried over coax cables in its earliest iterations. This is important to the product, as the whole value of MoCA is that it provides networking without requiring end users to recable their buildings. MoCA Access is designed to work with a variety of coax network topologies. Then, a MoCA WiFI extender or network adapter is hooked up at the other end to provide connectivity at the remote outlet. Often, it involves hooking up a router to a MoCA adapter at one coaxial outlet in the house. MoCA can potentially help in these instances if coax hookups are available. Common scenarios include when WiFi signals may not reach across a home, or where it’s desirable to get a wired network connection into a given room. 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.
