Competition heats up for triple-play home networking
(old news - 06:24PM Tuesday Nov 07 2006)
tags: business · bandwidth · networking · TVIP
Verizon uses 270Mbps capable Multimedia Over Coax Alliance (MOCA) technology for Fios installs. The standard allows them to avoid running Cat-5 and instead cut install costs by using existing Coax. AT&T started using MOCA for "Project Lightspeed" and U-Verse installs but then shifted to Home Phoneline Networking Alliance (HomePNA) technology. HomePNA allows for the use of either coax or traditional copper phone lines for home networking. HomePNA version 3.0 was to be integrated into the HD-ready Motorola set-tops being used for U-Verse IPTV.

Today the group behind HomePNA announced (pdf) the release of the HomePNA 3.1 specification, which the group says offers speeds as high as 320Mbps.

"HomePNA 3.1 operates over coax cable as well as phone wires and also provides multi-spectrum operation, adding VDSL coexistence to the ADSL, POTS and broadcast TV channel spectrum coexistence provided by the HomePNA 3.0 specification," says the press release. "Multi-spectrum operation also allows multiple HomePNA networks to coexist on the same wiring."

problem.

What happens if you have a VERY long drop how much does the speeds drop then?

Funny the telcos are trying to get one up on the cable companies but they still use Cable intresting.

Re: problem.

Yup.... I prefer HomePlug myself. Even though I've got 'old' Homeplug @ 85Mbps - its much more stable than wireless G (108Mbps) and better response. Just don't have one of those 50 year old refridgeerators plugged into the same circuit or have it plugged into a power bar. Newer stuff is good for 200 Mbps (so they claim), but only have 100 Mbps connectors

This is for distribution inside your house. The drop length is irrelevant. Do you even bother to read before you post?

Yes it does if you know anything about signal levels on long drops above 200 ft. Also the signal for digital needs more bandwidth in HDTV. So if you have LOW signal levels guess what MR. anon ( NO PICTURE) so yes it does matter.

Sure put a amp on your system but if your signals are low all your going to do is add more noise to the end.

Why dont you be a man and register with us???

As mentioned by MyTube, this is for use inside the home. What will be working on the drop to the home is a different animal.

There is a reason the wires are twisted together, it's called a pair. It defeats the whole purpose of twisted pair cabling by using the solid orange and solid green to wire the jack.

Some people live in ranch style houses that are long. Longer the cable or copper less signal you have.

I have 240 feet on one cable. loses of 8 db.

Re: problem.



A Ranch style house 240 feet long? That would have to be one long assed house. Or, was it just that the installer ran the cable all over the place because you wouldn't let them drill holes or fish the cable? Or, perhaps it's just some weird install?

I'd say the issue was due to the word "drop".

Anyways, I haven't found anything on distance limitations for the new specification, but "HomePNA Version 2.0 is designed to reach up to 1000 feet (300 meters) between any two adapters." »www.homepna.org/support/faqs.asp#FAQ2

Also considering that even 1000BaseT has a limit of 100 meters, I would think it should work fine on a cable run of 240ft or so. However, I have never used HPNA and not sure what real world performance would be.

That guy was Mytube, not me, Mr. Anon.

I don't register because I don't want to stamp my name on a place with such... rabid users. Some of the things I see posted are just really real bad to say the least. I don't think most times the forums would serve helpful, the exception seems to be the official services forums they seem ok.

I agree wiht your concerns actually I face the same thing, we have really long runs (cat5e) where I work and some people don't understand their drops were designed to go with maybe a 10 foot cord at most, but they want to use 20s and 50s and a few 100s and then they wonder why their network connection doesn't work or is really unreliable. Hell I wonder the same thing where I live, I wonder how Uverse (if we ever get it) would be done for an MDU. WOuld they want to build a special box where their network stops and ours begin or will the bring it into your unit then convert it. The wiring in our unit is foreign to me and I'm almost amazed that our DSL works.

No prob! Just register as . . . "Mr Anon" -- or any other psuedonym of your choice.

Who in their right mind uses his real name anyway?

Re: problem.

I have an online name I use everywhere and if I register I am then obligated by my own morals to give a thought about the place and what goes on there. Not saying that not doing it give me the feeling I can be a jerk and cut and run, just that I'd have to care.

However as I start to feel like "to heck with it all" about more things, I'll give it consideration.

They're using coax for the final run, not the whole way. They use fiber for the majority of the run, which is what matters.

Re: real world speed

I have the 200Mbps netgear.. in a new house. Despite what the internal tool says(40-160Mbps).. I find I can get a maximum of 25Mbps when doing ftp between laptops in the same room. From basement of house to 2nd it slows to about 3-5Mbps.
