MoCA Coax-Ethernet Adatper Kit (MCAB1001)

Which Networking Technology Is Right For Your Home?
By

Multimedia over Coax Alliance (MoCA) technology looks similar to powerline in many regards, only now we’re dealing with a theoretical 270 Mb/s connection over coax TV wiring rather than electrical wiring. 

In 2008, the net throughput spec with MoCA was raised (as of MoCA 1.1) to 175 Mb/s. This is the current generation shipping today, and we’re told that 175 Mb/s is the performance level end-users should expect. Documentation from 2007 and 2008 state that MoCA 2.0 was to have arrived last summer, bringing net throughput up to 400 Mb/s with forward support for 800 Mb/s. However, perhaps because the market has yet to even catch up with the capabilities of version 1.1, the next release is still pending.

Why look at coax when we already have powerline? You might suppose bandwidth, but today’s 200 Mb/s HomePlug AV isn’t that far from 270 Mb/s MoCA, at least on paper, and Netgear’s MCAB1001 devices, just like their powerline counterparts, use 100 Mb/s Ethernet ports. Reading MoCA’s literature, you might suppose it’s because of the market opportunity. “According to the National Cable & Telecommunications Association (NCTA),” states the MoCA brochure, “an estimated 90 percent of U.S. households are wired for coaxial cable. Most homes have multiple cable outlets. Coax is already connected to more than 300 million television sets and is the preferred in-home video distribution medium for more than 100 million cable and satellite homes in the United States today.” Of course, there are a lot more power plugs than there are coax jacks.

Perhaps it’s because of the highly-shielded nature of coaxial cabling, which could help prevent outside interference. There’s no need to worry about sharing a plug with other devices and no question of a power strip potentially fouling up a connection. Still, these seem like small considerations in the big scheme. Surely, some people will turn to MoCA after encountering problems with WiFi and powerline. But could it be that the real value proposition is based around service providers rather than end-users? After all, cable companies are experts in cable connections, not Ethernet, WiFi, or powerline. If the providers feel more comfortable offering and installing a certain networking technology, then the hardware suppliers stand to sell more.

Much like DSL, MoCA signals occupy the unused line spectrum for CATV above 850 MHz, so there’s no risk of interference from other data on the line. Although, if this were absolutely true, Netgear’s configuration GUI wouldn’t include the ability to scan for or manually select specific frequency channels. The software also lets you enable or disable encryption and perform firmware updates. In order to employ the utility, you need to set the MoCA adapter into config mode via a little button on its back.

Netgear bundles the MoCA adapters in pairs. Each unit has one Ethernet and two coax connectors (operating in a pass-through manner). The first unit connects to your router and cable modem. The second connects to your client device and/or set-top box for outputting to the TV. Other than that, it’s all pretty point and shoot. We found setup to be remarkably easy, with no configuration issues whatsoever.

Street price on the MCAB1001 kit is still in the $190 to $200 range—nearly double the cost of powerline. We’ll see if MoCA can justify this added expense shortly.

    I'll be bookmarking this article for customers who tell me, "No, I don't want a wired LAN, I picked up this wireless router at WalMart....."

    I like the netgear floorplan "Stairs to go upstairs" ... great!

    And nice article btw. Imo I'd have put the first rant about netgear after the section detailing that you're using it, so it looks more like an explanation than an advertisement (page 1) though.

    Thank you for the article.
    I decided to skip getting a switch (as I still want interent on all connected devices anyways), and grabbed a 2.4/5GHz 820.11n gigabit router...
    Has done well for me, just too bad my PSP can't use wireless N.

    I've been tempted (and almost did) put new holes in my walls to drag my cat6 cables around my house (I only grabbed cat6 over cat5e because of the colour of the cables at my shop, however I do somewhat regret it because cat5e is a lot more flexible).

    Q: can regular people like I download the zap benchmark software somewhere? I'm the guy being blamed if our corporate network in two towns breaks down, and lately I've been hammered for unstable wireless network and can't find any cause for this. Would like to see minimum performance for our access points (got about 40 meru aps with dual radio and a,b,g and n concurrently).

    Gigabit ethernet throughout the house running through a gigabit switch in the garage here with 802.11g for the laptops until I get round to replacing the router we got with our broadband supplier with an Airport Extreme.

    Luckily the previous owner of the house was a network engineer and had left all the wiring throughout the house. I just hooked up a cheap second hand gigabit switch off eBay and have been loving it ever since.

    If you connect a power-line connector from a computer that is also connected to a wireless n network, to that router... will it use both adapters at same time? or whichever to provide best speed?

    weird thought.. but yea

    Depending on the OS, but if you're running a standard microsoft os, it'll use whichever it detects a gateway on first. Has nothing to do with which is fastest or most reliable.

    Type route print in cmd if you want to see what it uses

    Gigabit Ethernet foreverr, why upgrade/strugle with connection types that perform slower ?? Today we need the best HD connection ever :D 

    wireless is and always will be sheeet !!!!

    Great post. One small remark though, instead of naming it "Which Networking Technology Is Right For Your Home?" you might've named in "A Netgear commercial", since you talk more about Netgear, than the topic. Dlink and Cisco rule!

    Any chance of a follow up guide on

    1. how to do the setup in software (Mac/Win 7/Vista/XP)
    2. Sharing files
    3. Streaming

    I'm in the process of setting up a Gigabit wired network around the house and I'm struggling to find any decent guides that take you trough the entire process, from selecting the hardware to streaming media.

    smoleGreat post. One small remark though, instead of naming it "Which Networking Technology Is Right For Your Home?" you might've named in "A Netgear commercial", since you talk more about Netgear, than the topic. Dlink and Cisco rule!

    You put dlink and cisco in the same sentence? imo you should be ashamed!
    If there's one thing I know for certain, then it is that nobody who wants something to work should buy dlink to get there!
    Once (2001) I built a complete infrastructure with dlink switches and wireless adapters. The APs didn't even last a year before I replaced them with some asus ones, and these got replaced by much better HP ones in 2005. And finally when I got a chance to replace the dlink junk with 4108 switches nobody even wanted the old ones! In the end I gave like 20 dlink switches with fiber modules away for free - it was cheaper than throwing them away!

    And over the years when people ask "My wireless connection sometimes doesn't work. When I restart my access point it works again. What can I do about it?" my answer is always "Is it Dlink?" and guess what - the answer has ALWAYS been yes.
    It's possibly the least reliable network gear you can aquire! I'm not particularily fond of netgears mediocre quality, but they're tons better than anything dlink can provide! By the way - buying expensive Dlink stuff doesn't make it more reliable either! I've had a DES-6000 (8 slot modular) break down because it became summer and the temperature reached 34C (have had HP switches enduring 57C without breaking down). And serveral of the DES-1226 although configured correctly with vlans would occasionally send all data to the first vlan until rebooted. You don't reboot network equipment! You just don't!

    As for cisco - it works, sure, but it's tons more expensive than any competing brand, and doesn't offer support for anything nobody else can. And on top of that it's slower than most other quality gear with the same feature sets.

    And when you're at it do an article about (free) CMS system choices for hosting your web and storage servers at home. We live in a time where anybody can get 50Mbit for the same money a 2Mbit cost 5 years ago.

    Also an article about how ip trafic is routed and how dns servers really work would be cool - cisco is teaching a theory, but it isn't how things actually work in reallife. For instance many isp's provide a link where the 'network number' is the client pc, and the 'broadcast address' is the gateway ; according to cisco this shouldn't work, but it does.

    Going wireless for gaming is like buying a MAC over a PC. Its all hype and the look-at-me-im-so-cool thing.

    OK, i've been wanting wired ethernet at home for a while and this just makes me want it even more.

    Anyone knows of any good tutorials on wiring the house? making the holes on the wall and running the wiring?

    no it would not, you would have to choose which network connection you want to use between the 2. but it provides a backup if your main one is down.

    Definitely a combo of Gig-E and Wireless n.

    My laptop already has Wireless n, now I just need a new motherboard* for my desktop with gigabit ethernet and a new router
