Abstract
A system and method for performing free space optical communication with a plurality of streetlamp assemblies. The method includes transmitting a light beam from a first free space optical (FSO) unit of a first streetlamp assembly to a second FSO unit of a second streetlamp assembly along a transmission path. A transmission error is detected while transmitting the light beam along the transmission path. A location of one or more smart minors is obtained. An alternate transmission path is determined from the first FSO unit to the second FSO unit or a third FSO unit. The alternate transmission path includes a reflection of the light beam from the one or more smart minors. The first FSO unit is oriented with respect to the alternate transmission path. The light beam is transmitted from the first FSO unit along the alternate transmission path.
