This talk explore an over the air optical wireless network and to create a network architecture for reliable high data rate free space optical networks that can interoperate with traditional wired and fiber networks. These networks will have significant impact for applications between ships, airborne vehicles, satellites and land-based cloud computing and data centres as an integrated high speed information system. Throughputs of well over Tbps can be supported by the network, which is compatible with next generations of Ethernet at 100 Gbps. The big challenge is to engineer the free space optical wireless network in the presence of atmospheric turbulence and weather, so it will behave properly when interfaced to other wire-line networks and for the protocols of the various network layers to interoperate end-to-end in a heterogeneous network setting.
