Broadband

shieldssecurity · 22-01-2010, 23:37

Hi,

I've got a customer who has broadband in his house and he now wants it in his barn.

The barn is about 90 mts from the house and the only way i can get to it from the house is suspended overhead.

Can i use the external 4 pair BT cable and if so do i connect it using rj45 plugs

thanks

Is the customer on cable or adsl, also is there a router involved and does he want broadband in the house and barn??

For that distance you'd have to use a suspended Cat5e (or even better CAT6) cable (cable cannot support itself over those distances so you'll have use a support wire)

i think they are adsl. i can us a cat 6 but whar type is ok for outdoor use

Wouldn't be better to bury the Cat6 or attach it (to somewhere like a wall or fence)?
I can't really see it lasting all that long being suspended, with the good 'ole UK weather, especially at that distance.

Cat 5e or cat 6

thee is nothing to attach it to so i will have to use catinry wire

My main worry if it's suspended for that distance is surge protection.. Any lightning within 10 miles will probably fry the router/hub

The most ideal situation in my opinion is to dig a trench and stick the cable in some external trunking made watertight.

Suspending cable over that kind of distance isn't really the way to go. If theres a fairly large budget then a laser link would be better if theres line of sight.

I would also avoid overhead CAT5 or 6 cables. They tend to like being hit in thunderstorms.

Digging a small trench and laying the cables in a plastic pipe for added protection is probably best.

You could always hook up a couple of cantennas and get you a wireless link over that distance with ease.

First thought was "homeplug", but: http://www.homeplugs.co.uk/acatalog/faqs.html
Going to outbuildings with them is not certain, as the consumer box and cable length may lose too much signal.

So maybe wireless using gain antennas is the best way - not sure if you can use a directional + non directional combination in "MiMo".

For the cable route, use a top grade surge protector with network protection at both ends, preferably one with a "connected equipment warranty"

What`s he doing in a barn that needs a broadband connection?

Silly me

The cows need internet access!

joke btw

Seriously you need to get digging, preferably at least 10 to 12 Inches deep, maybe get some bundles of plastic conduit to run it in (you can use elbows, etc to run it in nicely).

Maybe also recommend a surge protection lead like http://www.pcworld.co.uk/martprd/pro...n/410UK/007195

Ok, how about this one...................................can i not just extend the BT line into the barn using the proper BT overhead cable and then do something with the broadband then.

is it possible to have 2 hubs coming off the same telephone line???

Kymmy · 24-01-2010, 10:13

I take it it's an ADSL system. In that case NO you can not have two modems/routers coming off the same telephone line (hence you were asked the question in post #2 whether they wanted it in both locations)

The ONLY safe ways are as follows

Get BT to put in a new phone line (Not an extension) (or get vm cable routed to the barn) and pay for a 2nd broadband
Get a decent Wifi system (probably a N rated 5ghz bridged system with directional antennas)
Get 100m of CAT6 and bury it in conduits

A suspended cat6 will work, all the way until the nearest thunderstorm which will probably drop out the entire network (the cat6 and suspending wire will act like a huge ground plane for interference and surges). You could get shielded CAT6 but it's really expensive and means extra weight and might still not protect you from local lightning (it doesn't need to hit the wire to cause a surge, anything within 10 miles can cause enough of an EMP

No brainer imho, though 2.4GHz not 5. I doubt wireless congestion will be a major issue there.

Cantennae as referred to earlier may not be super professional but 90m is easy for them.

Kymmy · 24-01-2010, 20:30

2.4 though at that distance will be to susceptible to interference from anything local within the area, I stated 5ghz as it's a lot better over line of sight with directional antennas
