Re: Transmission Bus
I was asked to figure out why a point to point link between two sites of a medical centre - roughly 150m down and across a city street - were dropping out a few times an hour with "no discernible pattern".
After sitting on the roof beside the link for some time waiting to see what happened, I found that the person seeing no pattern was either comparing hour to hour or not applying any level of fuzzing to what could be seen day to day. There was a railway overbridge between the two sites, and the drops were when a train got in the way. Trains run a bit off timetable all the time so there would be slight variance in times.
Raising the masts permanently would have needed planning permission; but we did it temporarily while ordering cable internet to both sites
