RF Anywhere…Over Any IP Network

Kratos RT Logic’s SpectralNet eliminates the physical distance limitations in RF signal distribution, enabling the optimization of ground infrastructure to improve flexibility, reliability and reduce costs.
​SpectralNet is the first product to digitize and transport RF spectrum over IP networks in a way that preserves both frequency and timing characteristics, and then faithfully reconstructing the original RF signals to enable processing, recording or retransmission at another location.
