When I worked in Soho, we had a laser link over the rooftops of London.
At the time a 155Mbps ATM link, which we later used for 100Mbps Ethernet.
Main problem was cleaning the lenses every so often, in the lovely
London air conditions.
We later put in a gigabit laser from Nbase to another building.
We needed much more bandwidth than 100Mbps in the end, and had our own
trench dug and put in dark fibre.
