A Windows Media Center extender is by definition "connected to the HTPC where Windows Media Center is running". And that connection must therefore be through an Ethernet connection, no doubt facilitated via a router and multiple Ethernet cable runs between the various boxes and the router.
A similar "whole-home" topography using MoCA is implemented with the Motorola DVR equipment, with the "server" (representing the HTPC for WMC) and "clients" (representing the "extenders") as satellites, interconnected with standard coax in the home instead of using Ethernet cabling.
However as I've described previously, if you have an old "coax run" in your house (RG6 or RG59 cable, either will work) you can convert that physical coax leg to an "Ethernet run" by using "ethernet over coax" adapters. I have done this TWICE in my house (where it was either impossible or undesirable to run a new Ethernet cable, or there already existed a coax run that was going unused).
One time I used Gefen adapters
, but these are no longer made. These had the design where one was the "source" (nearer to the router) and the other was the "target" which actually had 4 Ethernet RJ-45 jacks on it (like a mini-router). So you could deliver 4x100 conceptual Ethernet legs through this pair of boxes. Four separate 100Mbps outputs at the "target" end, to feed up to four separate Ethernet-enabled devices at that end.
The second time I used Netsys adapters
, and these ARE currently available and priced well. Either end can be used as source or target, and both boxes have two RJ-45 connectors.
In fact, BOTH of these "ethernet over coax" runs (with both Gefen and Netsys adapters) are active and in use in my house. In fact, the Netsys leg is a secondary offshot fom the 4x100 end of the Gefen leg. I had a coax run from the router area to the front family room, and converted that to 4x100 Ethernet using the Gefen adapters. One of the 4x100 outputs goes to my DMA2100 extender in the family room. A second of the 4x100 outputs goes to feed one input to a Netsys adapter in the same shelf. Then I have a second coax cable run from the family room to the kitchen (where it used to feed a SD kitchen TV via "channel 3" out of a DVR in the family room). So that coax leg from family room to the kitchen is now part of a Netsys ethernet-over-coax pair, to feed another DMA2100 I now have in the kitchen to support a new HDTV I put there to replace the old SD CRT kitchen TV.
So I have one DMA2100 in the family room, and a second DMA2100 in the kitchen, both being sourced through the two coax legs and four ethernet-over-coax adapters, via the router and the upstairs HTPC. I have a third DMA2100 in the bedroom, fed "legitimately" via Ethernet cable from the router (which I ran to the location, as it was feasible to do).
No need to think of MoCA here, even though it's standard 75ohm coax providing the connectivity. It's "ethernet over coax" to connect to the WMC extender, which is specifically the type of connection the Echo expects... Ethernet, to the HTPC where WMC runs.Edited by DSperber - 10/11/12 at 5:40pm
