RE: FN-FORUM: Network over ringmain

I've a client who's got a farm and wants to network the packing shed to =
the main office. There is a cable trunk between the two that carries a =
phone line and power line - distance is about 100-150m. He's tried his =
wireless network up in the shed but there's no signal - not really =
surprising given the distance and buildings in the way. He could install =
a booster or change the aerial on the wireless access point or he could =
install a repeater half way - which fortunately is in the piggery so has =
power.

What's going to be the most cost effective way - what's the limit on a =
standard cat5 cable run, I've seem 100m mentioned but is that an actual =
limit and anything over that would cause problems or does it simply =
start reducing the speed. It wouldn't matter if it was running at 10mpbs =
over the distance.

Any real world advice would be most useful.

Cheers
Andy

Hello

I suggest that you don't invest in such a technology yet as it has quite =
a few problems in real-life environments.

The suggested 85 Mbps speed remains in theory, and is only possible =
under optimum conditions and between short distances (a very well =
designed power infrastructure free of pikes, surges etc. and no =
replicator / extension plugs in use anywhere in the grid.) the real =
speed you experience is usually 10 mbits and sometimes even lower than =
that if you have a big house with lots of high power appliances (ovens, =
heaters, AC units etc.)

If your aim is to connect 2 Pcs together, I would suggest investing =
around =A350-60 in a wireless router (PcWorld sells packages that =
include wireless adapters for laptops or desktops.) that usually =
provides 54 Mbps even under slightly unfavorable conditions (like thick =
walls) and usually even more (up to 108 Mbps by using the right =
channel.). After this initial investment, it's possible to connect =
additional computers to the network by purchasing an adapter for each =
PC. (usually costing between =A315-25 each.) Each wireless access point =
/ router can support up to 30 PCs without any performance penalties. =
After 30, it's best to get a secondary access point.
