it looks like I’m using 1150 and up on the moca adapters, and getting around 3600 speed on them per the UI. What can I do to be prepared for the 3.1 gigabit upgrade if spectrum uses high bands.
A crash course in meditation?
I have an extra POE adapter, would putting one on the end of the coax going into the 3.1 modem work?
Some DOCSIS 3.1 modems have been seen to be unstable if a MoCA network is operating at a frequency within the DOCSIS 3.1 range for which the modem is spec'd, so installing a MoCA filter on such a modem's coax input has been helpful as a prophylactic in protecting such a device from the MoCA signals. That said, being able to use a MoCA filter in this way depends upon what DOCSIS 3.1 frequencies are in use by your provider; if the provider is employing frequencies within the MoCA filter's stop band, then another solution would be needed.
Of course, if your provider is using these higher DOCSIS 3.1 frequencies, the main "PoE" MoCA filter (the MoCA filter at your cable signal point-of-entry) would be similarly problematic. In fact, to accurately assess what DOCSIS 3.1 frequencies are used by your provider, you'd need to ensure that the path from your provider to your modem/gateway is free of any MoCA filters; they could be replaced if/when you determine the frequencies in use. (Keeping in mind that operating a MoCA network w/o a "PoE" MoCA filter is a security risk.)
Or maybe only using higher bands for moca? Even if that drops the moca speed to 2000 or so from 3600, it’s still more than the gigabit lan stuff it’s plugged into right?
Aside from a separate, dedicated coax line for the modem/gateway, this is the typical backup if the provider is using DOCSIS 3.1 frequencies above 1002 MHz. The initial rollouts of DOCSIS 3.1 are supposed to leave room for MoCA, provided the MoCA gear allows for customizing the frequency range in use.
It would seem
@gocoax is aware of the need based on this reply on the subject of MoCA 2.5 and DOCSIS 3.1:
DOCSIS 3.1 have the frequency range up to 1218MHz, MoCA frequency range is 1125-1675MHz. There is some overlap between them. If you really want to use DOCSIS3.1 and MoCA together. Maybe the following suggestions are useful:
1, Connect MoCA adapter and Cable modem to RF splitter directly.
2, Use a special MoCA adapter with special band filter, the lowest frequency is higher than 1218MHz. configure MoCA adapter to use 1350-1675MHz.
3, Or use special external band pass filter for the cables connected to MoCA adapters. the higher frequency is up to 1218MHz. configure MoCA adapter to use 1350-1675MHz.
We really wants to test Step 3, but we only have DOCSIS3.0 cable service.
One issue I haven't seen addressed is what a user is supposed to do about MoCA security at the point-of-entry if DOCSIS 3.1 signals above 1002 MHz are in use -- and so the typical "PoE" MoCA filter couldn't be used. (I haven't seen a MoCA filter with stop-band starting at 1300 MHz.) This points back to the preferred solution of a separate, dedicated coax line for a DOCSIS 3.1 modem/gateway, allowing MoCA to operate as before over the original home coax plant.
. thanks!
