As a result we have installed a wireless point-to-point link on our nearest visible and accessible roof top.
New Wireless Link
We have a couple of point-to-point wireless devices we keep for emergencies and temporary bodges that we have set up before (pictures of these below), but as we have a large building to feed with a number of staff and students as well as PC's to image we were looking for something that could provide closer to a gigabit connection. From throughput tests it seems to work well and a fibre can go in the road at a later date.
