# MoCa - Ethernet over Coaxial

This is specifically a high-level hobbyist question, I'm not really looking for schematics or anything of the sort.

To deliver Ethernet over Coaxial, what sort of high-level designs or common issues will I need/face in completing this task? Initial research found that this technology is also referred to as MoCa, see:

Multimedia over Coax Alliance

From my understanding, I need to essentially build two modems.

I'm just looking for a starting point to begin my own research, any help is very much appreciated.

• This question may be closed as being a bit too broad. Sounds like an interesting project however. To start with you should probably define exactly what your scope is, i.e. do you want to implement all of the Ethernet protocol yourself and so on, maybe look at some existing FPGA/microcontroller implementations – jramsay42 Apr 22 '18 at 10:54
• Ethernet was originally implemented over coaxial, first using transceivers attached to the cable and connected to equipment via transceiver cable, then using thinner coax with the transceivers built into the equipment. Read some history? – Finbarr Apr 22 '18 at 10:59
• Fair enough. Cheers for the help guys, this is very helpful. – Naxin Apr 22 '18 at 11:01

• Thanks for the suggestion. At a $180 AUD price point I wonder how the fully built solutions can be only$100 imported. Any comments on the price? – Naxin Apr 25 '18 at 9:26
