And that's the crux of the proble. It was costing us £200+ to do each install and the punters would not pay that. You need people with insurance and ladders - specially if you're going to drill into peoples houses. We used local sky installers and they weren't cheap. Do it yourself, crack some external render/plasterwork and you've suddenly got something more to wory about than just putting a cable through the wall...
And one p2p'er will kill the lot.
We got just over 100 people (out of 1800 houses) to put their names on a bit of paper in one town. This was after running an 18-month funded project to raise awareness and research the effects of broadband in a rural community. Then barely 50 committed to the install of £99, which was less than half what it was really costing. Our first customers cheque bounced on us. Then trying to get £25 a month out of them was like pulling swords out of stone )-:
On paper, 50 customers at £25 looks good, but the running costs (without staff) were close to £1000 a month - to buy the backhaul, pay for space on the masts and farmers, etc.)
Do yourself a favour and don't do it.
You don't need woks - I recently did help a friend in Wales as it happens, to get a link to his neighbour about a mile away - good line of sight at roof-top level using older, but good outdoor kit with flat-plate antennae. (smartBridges kit)
The longest wi-fi link we ran was 6.5 miles in Cornwall using a standard
12db omni at the access point and and an 18db grid parabolic antennae at the client end. Good line of sight though - client was uphill from the base.Gordon
