How to Transmit Ethernet Over Coax

Ethernet networking is the most popular wired networking technology for personal computers. There are two major types of Ethernet: 10Base-T and 100Base-Tx. Each uses a specific type of connection to the network hub or switch that provides access to the other computers on the network. Here’s how you can use coaxial cable to connect your PC directly to another computer or connect several computers together, creating a private network that doesn’t require a hub or switch.

The technology used is called MoCA. It stands for Multimedia over Coax Alliance. Depending on the Generation, MoCA is designed to transmit at speeds anywhere between 200 Mbps to 5Gbps of data over coaxial cable, with room to grow as new technology is developed (800Mbps and 1 GBps are in the works). The closest thing to MoCA on the market today is called HomePNA — but it doesn’t approach the speeds of MoCA, and most of the manufacturers of HomePNA equipment are abandoning it in favor of MoCA.

MoCA is a high-speed communication standard for home networks that can be used to Transmit Ethernet Over Coax. It allows you to use the coaxial wiring already installed throughout your house by plugging one device into the modem and another at an end point near where there’s free space close to cable jack (or other place). The MoCA design balances data rates, channel capacity, power consumption levels while taking out interference from neighboring channels so it has been shown to give higher speeds than Ethernet over UTP/STP or HomePlug AV2 up through 300 meters of line length without using repeaters which means longer distances are possible when upgrading.

Ethernet over Coax, or MoCA for short, also know as Multimedia over Coax Alliance is the newest way to give your TV a fast and reliable Internet connection. The adapter works by plugging an Ethernet cable into one port near where you live router and connecting it with another that can be located anywhere in close proximity of your television so long as there’s coaxial wiring nearby. This setup will allow remote access without interference from neighboring networks while still remaining consistent enough to stream content reliably on demand – all at no additional cost!


  • MoCA 1.1 provides 175 Mbit/s net throughput rates (275 Mbit PHY rate) and operates in the 500 to 1500 MHz frequency range with a maximum aggregate bandwidth of 150Mb, which is 3x faster than MoCA 2.0’s 54 Mb speed capability!
  • MoCA 2.0 provides fast and reliable internet for your home with speeds up to 1 Gbps! Operating frequency range is 500 to 1650 MHz, which means that it’s optimized equally between the two predominant frequencies in order to eliminate interference. Packet error rate only comes out at one packet per 100 million packets sent – a feat unheard of before MoCA 2.0 came along! MoCA offers outstanding speed coupled with incredible reliability through its next-generation technology: MoCA2 (or “Version Two”). It operates on an operating frequency bandwidth from 500MHz up until 1650MHz, giving you optimal performance no matter what type of device might be running or interfering nearby without sacrificing network security.
  • MoCA 2.0 offers lower power modes of sleep and standby so that the device can be used at any time without worrying about battery life, while also being backward-compatible with MoCA 1.1 for use in older homes or newer providers’ networks
  • MoCA 2.5 (introduced April 13, 2016) offers actual data rates up to 2 Gbit/s and is backward interoperable with MoCA 1.1 and the latest version of MoCA at speeds of 5Gbps.
  • The MoCA 3.0 standard will lead to an increase in the maximum throughput from 1,000 Mbps to 10 Gbps!
