Weird Pipe Found Buried in Yard

While I agree that it's good to have the cables separated, I would be very surprised if anything above 10GB/sec was common for home use in

My guy says the trend will be back to wired, because wireless is getting too clogged up. Wired is still faster and more reliable and will be for the foreseeable future or until they find new frequencies. :-)

I don't believe that at all. Antenna diversity and MIMO solve these problems in all but the most dense living situations.

There is such a thing as "fast enough". We have exactly one wired link in our house (that the cable company put in), basically because there's no point in adding any more.

In is unsafe to take a chance with high voltage crossing over to a consumer device. There is also the electromagnetic effect, especially on an A/C system with its varying loads. On systems with variable speed drives there are multiple problems, and it is also a Code violation in most places. It is not even recommended to mix land line phone lines in the walls, or conduit, and any box.

The twist in CAT cables knocks out a lot of noise but not all noise.

There are more technical reasons as well, but I'd have to look it up, I just recently threw away all my books, manuals, etc. figuring I have been retired long enough that I'd not ever need them again. :)

Have you ever seen someone zapped with high voltage when they touched their computer case? Yes, I know the in most cases the NIC will act as a fuse, but not always.

Yes, it is the biggest reason, but when you get network speeds running really slow because of the crap interference, and this being a daily issue it is quite costly.

I've seen T1 data lines running at 2mbits because of it, and a db backup that would take multiple hours as opposed to minutes because of it, add that to normal network traffic and it is ridiculous.

In one job I did a log of the bit rates over a period of time to show consistency of the loads and loss of data speed verses what a properly installed data line would do, and they ended up not only paying the money to replace the entire line but upgraded the speed so that there was no negative impact whatever was happening.

In that case they thought they could not afford the cost of replacement, and over a period of years they just got used to it and considered in "normal" for that site. So I basically invested my own time to do this and show them what their real costs were. After that their eyes were opened and they started looking at all their remote sites to see if they were getting what they were paying for.

I got nothing out of it, but thanks from the employee's that were effected. That was good enough for me.

Add 30ft. to equation and it's not fast enough anymore. I stream video to my garage/shop and it's not fast enough over wifi from

If the NIC acts as a fuse, the NIC was a piece of s*it to begin with. What part of "transformer coupled" are you having trouble with? Unless someone has screwed up there is NO contact between a twisted pair Ethernet cable and any part of the computer case, directly or indirectly.

Getting zapped by a floating ground with Token Ring or Arcnet or coaxial Ethernet are more likely occurrances--all of those use shielded cable with the shields grounded to the chassis. But those have all been dead for a couple of decades now.

Quite costly to some guy running cable from his house to his garage? OK, tell us exactly how much it costs him, in dollars, to be getting

You just blew your cred. T1 is rated for 1.544 Mb/sec. If you were getting 2 then it was exceeding its rated performance and you have nothing to complain about.

In any case, nobody is going to be running a T1 from their house to their garage on a CAT6 cable. What's going to be running on it, in

That's nice. What does it have to do with some guy running a wire from his house to his garage?

Well that's all well and good. So how much measured degradtation have you experiences in wires run from people's houses to people's garages carrying gigabit?

Actually you need a lot more if you are doing multiple TV's on the Net, computers, etc. I have High speed WIFI necessary because things move around here a lot, plus we can use it in the back yard and garage. With the grand kids here and online video games plus the video interaction you need a good home backbone, and I can certainly tell the difference between hardwired network to my HO computer verse wifi to laptops, phones and tablets.

The code violation is the real issue. A 250 Mhz circuit is not going to even see 60Hz unless it's of such magnitude that it generates an arcover in the isolation transformers.

Note that phone line considerations are different from data. 60Hz is audible--if you've got 60Hz interference on a phone line you can _hear_ it. A 250 MHz data line is another story.

He is right. Especially when you find out how easy it is to hack WIFI to the homes and businesses around you, especially on those that haven't a clue about security. Years ago I used to connect up and print out messages on their printers to clue them in.

Well, I may end up running a metal conduit along side to get the shielding for whatever data wire I run out there. When I was in TCOM, we microwaved everything, so maybe I'll just do that. :-)

Wait till you see a decent fiber optic system and the possible speeds and want to run 4k TV on wire for viewing new movies, especially on more than one TV at a time. with full sound, using limited compression and loss of musical tones.

Of course with the way my ears are going. :(

A lot more than TEN BILLION BITS PER SECOND?

How old is your wifi? If it's not 802.11n at least, it's time to upgrade.

Wired is faster, but how fast do you NEED? I see no evidence of a trend to wired for residential use.

As for ease of hacking, this is mostly FUD. Has any data breach causing economic harm to anyone _ever_ been traced to a wifi hack?

Most data thieves don't go after Joe Homeowner or Fred's Pizza. They go after somebody who is likely to have enough in assets accessible by computer to actually be worth stealing.

I have no trouble running 4K TV over the built-in wifi in my TV. What leads you to believe that is has some enormous bandwidth demand?

As for "possible speeds", other than bragging rights what do these "possible speeds" get you?

It isn't as cut n dry as you might think. Run a scope on the signal look for the interference. If what you said were true you wouldn't need a certain amount twists per a foot of Wire.

There is that option, as well as WIFI with the right antennae's. We have installed systems at low cost that were acceptable over several miles.

A wired system might need a signal booster/repeater depending on the total conduit feet run. I'd be tempted to run an above ground test setup with a computer at the other end plugged into the power supply in that bldg and run a speed test via software and see if there are little to no problems.

I might have problems with being a bit overcautious here. :)

Twisted pair ethernet is unidirectional on a given pair. Gigabit uses four pairs, two carrying signal one way and two carrying it the other way. It's crosstalk on those pairs that is the major driver in the spec.

It is not designed to act as one, it is just that there is a certain chip in their that has a high failure rate and has actually save many computers as a result.

Pulling wires often scuffs insulation with resulting voltage bleed or high capacitance charge. Don't believe me, then run a megohm test on the wire to the conduit or attached motors. I have seen more than one erratic operating piece of equipment that was due to this and it affect all electronics associated with it.

I have also felt capacitance grounding by touching a computer and another metal electric device that had a proper ground and not just some two wire plug.

That is true as well.

What if he only got 2Mbps? WIFI can eliminate all that, and be less expensive as well.

It was actually a T3 for that case. You are right, and I have also been retired more than long enough to forget all the figures on a moments notice. I'm currently only concerned about what goes on here at home.

I also still have a few routers, switches and stuff, Cisco commercial products, wanna buy them and get them off my hands?

Of course not, the switchgear costs alone would be prohibitive, plus the cabling. But he could run fiber optics and never have any of the problems associated with hard wire systems.

If my creds are so important to you then you can call Cisco and see what all I was certified for at the time. I am not keeping my certs updated because I am retired. Get it?

Explaining or rationalizing why it is important to do it right in the first place.

I didn't do houses expect for friends. But the ground field for the bldg is a big issue in such cases which I addressed in another post.

If I gave you my full resume from all the years I've worked you would probably call me a liar too. Oh well. what's a guy to do?
