An experiment of laser beam propagation was carried out on 3.5 km urbanised path. The irradiance scintillation and angle of arrival were synchronously measured. The statistical characteristic of irradiance fluctuation and atmospheric refractive-index structure constant are analyzed. Estimates of scintillation fade margin for different scintillation variance and probability of fade for different fade threshold in free space optical communications are made. The atmospheric refractive-index are mostly above 10-14 m-2/3, and the scintillation index mainly range from 0.01 to 0.79, in the urbanised environment. The results can provide experimental basis for the design of free space optical communication system.
