Question 1

I have full home runs of RG6 quad, and will be looking to upgrade to 1gb service from my ISP soon, do these actually hit the marketed ~670 mb/s? I will be running Cat6 or 6a directly from the router to these, then using this to go from the wall to the computers.

Basically what I'm asking is do I need to run cat6?

Accepted Answer

Depends, these are essientally OFDM  (with subcarrier) modems. They operate in either the E or D frequency bands over the line. So the overall throughout will depend on the signal to noise ratio between the communicating nodes. Exactly like DSL modems, the multiplexer in the adapter will drop sub carriers on noisy lines, or if you have bleed thru from other services on the line (satellite, cable, etc.).

You mostly likely will only see >600Mbit on a quality run with few to no splitters and with only two adapters on the line. Expect a few ms of latency.

More than two adapters on the line expect >400Mbit.

Remember, this is a broadcast medium, so adding adapers does not ever increase throughput. The channel bandwidth is shared by all adapters.

On my setup, I used a pair of adapters to run Ethernet to a TV from a media server. 200 ft cable run with two splices in the run. I measure 610mbit. Which is enough to stream a 1080p compressed video. Perfect for my needs. My latency is ~4ms. If this is your setup, or if it's for general internet browsing, you should he okay. If you are gaming, the latency is probably too much, pull some cat 5e and use a switch. YMMV.

Question 2

The project I'm about to start is this: Input from Coax feed ( Time Warner) -->CAT6--> plug into Ubiquity Power Beam 400 --~RF Link~--Power Beam 400-->Cat6--> MoCA adapter--> (Coax)-->Time Warner Cable Box.
Looking for the TV and data thru-put on far end. With cable box on distant end, I should have ability to change channels and the such..Yes?

Accepted Answer

I don't know about the Ubiquity Power Beam, but everything else should work seamlessly.  I've used the MoCA devices is multiple applications and they work wonderfully.  You might get a bit of lag due to the multiple connections, but it probably will be imperceptible.  Good luck.

Question 3

Which model# is this unit, ecb6000 or ecb6200?

Accepted Answer

ecb6000.  These do not have the coax pass-through found on the ecb6200.
