sharing BB between 2 houses

adive please...

i would like to share a broadband connection between 2 house that are around
300 - 400 meters apart....

they have line of sight

i have seen equipment for sale that will transmit over such distances.

does anyone have any experience or knowlege of this kind of set-up ..
would this provide a reliable service or could there be issues with this
kind of set-up

thanx

kev...

WiFi with directional antennae. Preferably proper outdoor units. Maybe
£3-400 for a link, depending on the quality you want (& speed). You can
do it cheaper with indoor units and external antennae, but I've never
had good results doing it that way. (& I've built several wide-area
community broadband networks with various indoor & outdoor WiFi kit over
the years)

There are wireless solutions that go right up to 300Mb/sec, but you gotta
pay for those speeds!

It all depends on your budget and what you expect from it...

Can they be physically connected? If so fibre is a strong contender.
10BaseF is rated to 5000 metres, it is possible to pick up part reels
quite cheap, at a pinch a torch can be used to test continuity,
termination is DIY with a steep learning curve, terminating eqpt
whether AUI-FOT or fibre hub expensive, though eBay might come
to the rescue.

Would two USB wireless dongles be within visible distance of each other
(line of sight)? It probably wouldn't work if there are walls and part of a
building in between? If you can look past one and see the other then
set one to Station mode and the other to Infrastructure and see what,
if any, signal strength is reported. If you get a signal, then you can
add reflectors (dish or ali-foil coated card) to boost signal strength
of USB wireless adaptors. A couple of Netgear ME102's might be
worth considering.

There are (expensive) infra-red and microwave links available. The IR
links are an adapatation (of the now down to 3 quid) laser pointing
devices

The main issue is security with a wireless system, and ISP's terms
of service about sharing. If both users are heavy downloaders, or users of
streaming content, then bandwidth sharing becomes an issue.

Traditional ethernet would go 500m, but can you still get it?

USB dongles won't go 400m, however a card with an external well constructed
aerial might. At 2G4Hz, you can use a parabolic or make your own Yagi.

Again to go 400m (bidirectional) you will need something a little better
than a defocused board pointer.

Just set it up right.

Put a USB at the focus of a "chinese sieve" and it will!

Max distance for ethernet (10Mb) and fast ethernet (100MB) is 100m. It
may well go that distance but performance will degrade due to increased
risk of collision.

Get a wireless router, it's the easiest way to do what you need. Put it in
an upstairs room by a window facing the other house. Then ech buy a
wireless network card. Configure it to only allow the two of you access and
away you go. Use WPA on both computers and lock the MAC addresses to stop
everyone else connecting. The router will easily cover that distance, but
if there are obstructions buy a bigger aerial for the neighbour.
Easy solution.

Standard 50 ohm RG8 coax (it doesn't *have* to be yellow..!) Easy enough
to get, but the transceiver modules might be a problem. I've seen them
occasionally at amateur radio rallies but in any case the link would be
limited to 10Mb/sec. Ethernet cards with an AUI socket on aren't common
these days either.

Thin ethernet is limited to 100m but thick (if you can still get the
bits..!) should cover 500m ok. Still limited to 10Mb though.
