Considerations for building the network... A large variety of different communication media allows a most flexible network scenario (incl. features as rotating / alternative control centre): Note: PSTN lines (dialed or leased, up to 33 kbit/s) GSM communication (9.6 kbit/s with RLP) Radio Links (up to 15 kbit/s) ISDN (64/128 kbit/s (S0) to 2 Mbit/s (S2M)) Microwave links (19.2 kbit/s to 2000 kbit/s) Ethernet (10/100 Mbit/s) Dedicated digital lines, e.g. Fibre Optic Links (up to 2 Mbit/s) The above quoted figures are standard values. For each type of communication, considerably higher data rates are available on request. 8VTF-Eg/04 11 8 Spectrum Monitoring Solutions from ROHDE & SCHWARZ

Spectrum Monitoring - Management The Spectrum Monitoring Software R&S ARGUS comprises numerous facilities for measuring, monitoring, direction finding, evaluation and report generation. The Geographical Information Software R&S MapView displays DF stations, bearing results and transmitter locations on a digital map. Digital maps can be created or imported. The Integrated Digital Audio Software R&S AllAudio is an integrated software package for digital recording, playback, mixing and distribution of audio signals. A complete intercom system is also provided. The Spectrum Management System has facilities for planning and managing transmitters, billing, bookkeeping and report generation. 8VTF-Eg/04 11 10 Spectrum Monitoring Solutions from ROHDE & SCHWARZ
If we talk about... our understanding is Spectrum Monitoring System Spectrum Management System Spectrum Economy System maximize the efficient use of the spectrum minimize harmful interference 8VTF-Eg/04 11 11 Spectrum Monitoring Solutions from ROHDE & SCHWARZ
Spectrum Management Database Interface The Spectrum Management Database Interface (R&S SMDI) imports: transmitter data; occupied frequencies and; not assigned frequencies; This interface is used to: ARGUS-IT Monitoring System Spectrum Management System give input for spectrum engineering (reference data); verify the results of spectrum engineering; locate and identify unlicensed transmitters; locate and identify harmful interference; detect emissions with characteristics that do not meet license conditions; verify the transmitter parameters of licensed stations. 8VTF-Eg/04 11 12 Spectrum Monitoring Solutions from ROHDE & SCHWARZ
