A communication system (10) includes a pair free space optical (FSO) terminals (30a, 30b). The FSO terminals switch from a first operating mode to a second operating mode wherein the traffic is carried by an ad hoc network (40). The switching may be based upon a Quality of Service (QoS) parameter being exceeded. The first operating mode may be the primary operating mode, and the second operating mode may be the backup operating mode. |
