problems building a 'long' network

i'm trying to extend my 10/100 (10/100 hub) network with some friends who already are connected on a 10/100 network (10/100 switch)
the minimal distance between the 2 networks is about 250-300 meters (900 feet) so utp cable is out of the question;
i was thinking of a wireless solution but :

1.is pretty expensive
2.i dont know if it can handle the distance properly (almost no interference between the network "heads" ..only 2-3 walls)
3.even it can handle the distance,the wireless card works at 600-700 KBytes / sec at its best within few meters distance so at my distance it will be a real bottleneck (both networks are 100 mb)

what its ur oppinion ? what device do you recommend ? (i can put cable between the networks,it isnt a problem ... )

ps😛lease excuse my english

 
Looks like two options - wireless or wired. Wired would mean funning fiber optic cable (WAY more expensive than wireless but worth it).

Looks like wireless would be your only option. If you can "see" your friends window from your own that would be ideal. point the access-points at eachother with a good antenna and you might get 1 or 2 Mbs.

Better yet, just get DSL and talk all you want on the phone companies wires.
 
You can do CAT5 with repeaters on the middle.

I once network two buildings about 170 meters apart from each other. Made 2 cables, put a repeater on the middle and it worked fine.

You can use a dumb hub as a repeater. I would recommend cheap 100mbps switch instead.

So in your case, you would need 2 repeaters. It is going to be tricky. You might have to dig holes, look at manholes and pull a powerline to power the switches.

It can be done 🙂

btw:
Max CAT5 distance 100 meters (328 feet)
Max CAT5 distance with repeaters 500 meters (~1600 feet)


eRr
 
As an alternative to running power to power the switches, you should investigate the new spec for power over Cat-5. It uses one of the unused twisted-pairs to provide DC power; no need to run separate power lines!

I know that our Nortel 802.11 access points are configured to use power over cat5...
 
i was thinking of a low cost solution ... 2 access points = about 1000 $ (us $) here so that is not ....low cost ..if i put wireless pci adapters they dont have the option to modify the antenna to put a cable+antenna (or cable +more powerfull antenna) like the access point does plus i should use 2 more computers equipped with 1 wireless pci card and one network card as routers , each oriented 'back to back' in order antennas so 'see' each other

using adsl over phone line is not a soluttion phone is quite expensive here (not free like in the us 🙁( ) ...u meant adsl over a cable between the two networks spidey07 ?

hmmm someone told me something about thick bnc cabbles being able to work on higher distances(500 m) is that true ? if i would use that,i will create a bottleneck of 10mB,acceptable (in fact better than wireless or adsl)

i cant use repeaters(hubs) in the middle because some parts of the cable will be in air (95% of all cable is outside) so the repeater would stay out,in cold and rain 🙁 ...
 
I belive that Coax will work here. I you can find some old cheap hubs with the BNC plugs and then just run Coax between them.
 
fiberoptic tranceivers (100T to 100 FL) $150 or less a piece
fiber cable 1000 Ft $200 (guessing here)

gives you 100 meg full duplex with capability for gigabit ethernet.
 
I think regular coax is only a little bit longer than cat5 (maybe 150 m?), but thick coax is the long distance stuff. 500 m is really sticking in my head, I think that's the max length. I have no idea where you would get the cards and NICs though.

I'd use a media converter to go from 10Base5 (Thicknet) to 10BaseT on each end instead of trying to use NICs (Unless you want to dedicate a computer to do this on each end). If you need a NIC with an AUI interface (Thicknet) look for "Combo" cards, they have them.
 
I'm pretty sure thick Coax is going to be more expensive than MM fiber. did anybody remember the vampire taps? if you can even get them nowadays.
 
If these two networks are in separate buildings, fiber is a better choice from the perspective of potentially lethal differences in electrical potential on the wire.

Yeah yeah...I know. Properly grounded chit is safe. First time a thunderstorm rolls in, I'll let YOU hold on to the cable (thank you very much!)
 
If you use fibre:
The cost of fibre isn't your main worry... it is getting it terminated. I would use ST connectors because they're the cheapest and that is your main concern. Some questions you have to ask is: Do you know someone who can repair fibre if some fool cuts it by accident or on prepose, because this will cost you dearly. And how much can you get RJ45 to ST media converters for (or ST network cards)
If you use Coax:
You will have bottle neck... sure, but what are you using the network for? Is 100 meg THAT important?
You can use your standard network cards and hubs... all you will need is an RJ45 to BNC converter or an RJ45 to AUI converter depending on what you want to use (Make sure they're powered).
Coax cable is a piece of cake to get hold of... No one wants it anymore so I am sure that if you ask around you could find someone upgrading there network who is throwing away all there coax cable, or willing to sell it to you at a good price. You can put joins in it too. BUT the risk of the thunderstorm is quite real. So try to burry the cables where ever possible (in some sort of protective pipe or tube).

Wireless could be your best option... no cables to worry about and the freedom of being able to move location without the big pack up!

You can get more than 100mtr's from CAT5e cables... but then you have to get shielded cables (STP) and making sure there is NO break in the cable from node to node... I think you can get about 150mtr's from it MAXIMUM, but 250mtr's would be out of the question. So you are left with the problem of repeating the signal somewhere in the middle... hmmmmm might be worth investigating phone lines...

With no power between the buildings you have quite a problem. Good luck. 😉
 
yep,no power between the buildings 🙁( (i was thinking of putting a hub in the middle powerd by a long shieded cable, and using stp but thats too complicated and insecure )
i guess ill go for wireless ..altough is pretty expensive ..btw i cant seem to find here HomeLink Phoneline products 🙁(
