PoE over MoCA at gigabit speeds?

[DominikHoffmann]

I have been looking into MoCA products. A client on mine has coax cable wired to almost every room in the house, for purposes of distributing the cable TV signal. Since her cable TV subscription is going away and she wants to set up good WiFi coverage throughout her sprawling home comprised of 1929 construction and two later additions, I am proposing to utilize that cable via MoCA adapters as fast backhauls for individual WiFi access points (APs).

If I could run dedicated Cat6 backhauls to each AP, that would be better, of course. Then the much more elegant solution would be to power the APs from a PoE switch. Unfortunately, with the way the home is constructed, this would be prohibitively expensive. The cost of installing the wiring would likely exceed the cost of the hardware by quite a bit.

The problem with the MoCA adapters is that I will need a powered MoCA adapter at each coax outlet and, in addition, a PoE injector to power each AP. I don't like the clutter.

I have come across adapters MoCA that can transmit power for a downstream PoE device, but those only transmit at 100Base-T-equivalent speeds. See:

LINOVISION POE Over Coax adapter

Does anyone know of devices that accomplish the same, but are capable of gigabit speeds?

I think such product is not like a MoCA type. I have found many MoCA products with even more than 2Gb but not with PoE. And the PoE over Coax type adapters/converters are most 100Base-T.

Well, that’s exactly what I had found. However, I don’t think that Power over Coax (PoO—my coinage, not a standard acronym) would be physically limited to 100 Mbit/s. Somebody should come out with a 1 or 2.5 Gbit/s PoO product with conversion to Ethernet. Why hasn’t anyone?

Lack of demand would expect.

if there was sufficient demand someone would come out with one.
