A condensed-cyclic compound represented by Formula 1 below, and an organic light-emitting diode including the condensed-cyclic compound. The spectrum analyzer receives carrier signals transmitted from an orbiting spacecraft. The cathode assembly includes a sputtering target. The load is balanced by routing the user plane packet to a network probe that is either already analyzing the session-instance or by routing the user plane packet to a system that has processing capacity to analyze a new session-instance.
