Netgear MoCA Coax-Ethernet adapter
Have you ever wondered why you can’t use the existing coax cable in your house to stream things like HD around the house? Sure WiFi and powerline modules work for some, but unfortunately they don’t for everyone. So if you’re still looking for a way to stream data like HD around your house and are at wit’s end, the Netgear MoCA Coax-Ethernet bridge might be prefect for you.
Although we were just kids when all the world’s computers connected to each other via a coax cable, we still recognize the throughput potential of the medium. This and the fact that just about every home in America already has coax running through its walls has always made us wonder why we couldn’t utilize those wires to connect our computers. If you’ve wondered the same thing, then MoCA might just be for you. It is a CableLabe specification that allows devices to utilize the unused bandwidth on the coax at your house to send bits where no other medium can. So if you’re sick of trying to stream HD via Wifi and power-line technologies, you’re going to really want to click through and read about how these babies work.
The concept
This is a new device so we think a little introduction is in order. While this little box looks like a switch it’s really a bridge, in fact it is a Ethernet to coax bridge. You need two devices to get started, but can use up to 16. Each one has two coax connections and one Ethernet. The coax acts as a pass through so you can continue to use the coax cable for its initial purpose — you know cable TV or an ATSC antenna (not compatible with satellite). With these you can add a network connection anywhere in your house you have a coax cable running.
The best example
Lets say you have one of those new LG Blu-ray players that can stream HD MKV files from your PC, but you don’t have a network connection behind your HDTV. You’ve tried 802.11N WiFi and power-line adapters, but they just don’t cut it. So you grab a pair of these and plug one in to the coax running to your cable modem in your office, and you put the other one behind your TV in-line with the cable running to your TV. Plug the one in the office into your switch and the one behind the TV into your Blu-ray player — sadly it only has one port so your Xbox 360 and PS3 can’t play without an additional switch — and now you have 100Mbps of throughput, which is more than enough to stream any HD movie you’ve got with bandwidth to spare.
Conclusion
If all of this sounds great, then you know there has to be a catch. Well the catch is the price and at $200 per pair, you’re probably going to want to try some cheaper alternatives first. The good news is that unlike the alternatives this does work as advertised, and considering this is a first generation product we expect the prices to come down. So if $200 sounds like a deal to get a network connection fast enough to stream high quality HD anywhere in your house where you have coax, then we’d say; go for it. You won’t be disappointed.
