MoCA technology is used by your Cable Internet Provider to deliver Internet signals in your home or apartment via your existing coaxial TV wiring. MoCA technology forms a MoCA network within your home, talking with your MoCA-enabled devices to deliver your Internet signal to each device in your home. However, MoCA technology can seek out other “like” MoCA devices unless you stop it with a MoCA filter.
Some cable modems have a MoCA Immunity Filter already built-in to prevent your MoCA network from being seen by your neighbor’s MoCA network. If your cable modem was professionally installed by your Cable Internet provider, chances are you already have a MoCA filter on your line or built-in to your cable modem. However, if you purchased your cable modem on your own, you may need to look into getting a MoCA filter.
What Is a MoCA Filter?
A MoCA filter (MoCA immunity filter) prevents your MoCA network signals from interfering with your neighbor’s MoCA devices. The MoCA filter isolates your MoCA network away from other MoCA devices outside of your home MoCA network.
MoCA filters exist in two places for two different reasons:
- At the point-of-entry of the cable coming into your home/apartment
- At the point-of-entry to your cable modem/router
While your Cable Internet Provider should have installed a MoCA filter when installing cable Internet in your home, you can also take matters into your own hands when buying your own cable modem. One must-have feature for your MoCA network should be a MoCA filter.
What Does a MoCA Filter Do?
The purpose of a MoCA filter is to make sure that there is no MoCA Internet signal interference with your neighbor’s cable Internet signal. You must have at least one MoCA filter at the point where your coax cable enters your home or apartment.
Do You Need a MoCA Filter?
If you are using cable Internet (MoCA) signals, then yes, you need a MoCA filter. In general, using a MoCA filter is as much a safety measure as it is a courtesy to your neighbors. If you have devices that do not use MoCA technology and MoCA signals, then technically no, you do not need a MoCA filter. However, keep this in mind:
If you live nearby other homes or in an apartment building, and it’s likely that your neighbors have a MoCA-enabled device, you will want a MoCA filter because it keeps your MoCA network and signals private.
