Thanks for your reply.
I finally got 3 of the ActionTec ECB6200's which are bonded Moca 2.0 adapters rated at 1Gbps. After a lot of research on the Comcast forums attempting the same thing, I actually got it working in less than 30 minutes. I was able to achieve the maximum 150Mbps speed using speedtest on the furthest adapter from the cable modem (I have 150mbps internet service). Average speed was about 130Mbps which is pretty good considering I had one portal playing a recorded show, another portal playing a netflix movie, and the PVR on channel 104. This is all using the same coax cables that bluesky uses.
Although the actiontec website says that ecb6200's are plug-and-play and there is no configuration available, there is actually a web gui that one can log into and change the parameters of them. This is key to getting it working with Bluesky. If you just plugged it into the same coax as Bluesky with no configuration, they will not work.
Before you hook it up, they need to be configured as follows:
password = 12-17 digits (required) (default none)
privacy = on (required) (default off)
rf frequency = 1550Mhz (default 1150)
rf band = Band D High (default band d Extended)
Bluesky uses Band D Low at 1150Mhz.
According to the Moca 2 spec, setting the password and privacy on will create a separate moca network on the existing coax cable. Then you test the adapters by hooking them up together via a coax cable to ensure they can communicate (coax light comes on).
After verifying the settings and making sure the adapters communicate, you can add it to you existing home coax. For myself, the network looks like this:
=> 2 way splitter
===> 1. ECB6200 >-- ethernet out --|
===> 2. Hitron <-----gigabit port ---|
Basically, one split goes directly to the Hitron, the other split goes into the ECB, then the Ethernet out goes to one of the gigabit ports of the hitron.
The other adapters can go into any other room with a wall coax. Like this:
=> 2 way splitter
===> 1. PVR
===> 2. ECB6200 ---ethernet cable >--- Access Point or computer
All of the 2 way splitters used were from Shaw (they are the BGI series rated at 5-1000Mhz 3.5db each split). I could get moca 2 rated splitters rated at 5-1650Mhz but not sure if it would make much difference.
The house was built in 2002, so I'm not sure what kind of coax was used in the house (RG59, RG56, or RG6).
I have tried other configurations such as eliminating the splitters and using the TV out of the ECB6200's, like this:
===> coax out => hitron<--|
----> ethernet out --------|
But I got some inconsistencies in transfer rates. Plus, I realized that if you ever need to take out the ECB6200, you basically take down everything attached to it (ie. the PVR attached to the TV out). Having a splitter before the ECB allows you to move adapters around without disrupting the bluesky network or the Internet if the Hitron was attached.
So, in conclusion, over the same coax, I was able to get both a Moca 1.1 (Bluesky) and a Moca 2 network running separately from each other.
Over the next week, I'll be doing some more tests. One is trying to load both 1.1 and 2.0 networks to see what kind of limitations there are. For example, transfer a large 10GB test file over moca 2 while simultaneously watch 2 netflix shows and watch a recorded show (I have a PVR with 2 portals).
