R&S®PR300 - Elevated spectrum monitoring for regulatory authorities

Your task

The electromagnetic spectrum is undergoing a radical transformation, becoming increasingly crowded due to the expansion of high data rate applications, IoT connectivity and wideband cellular technologies like 5G. For regulatory authorities, this congestion means traditional narrowband signals are being replaced by complex, wideband transmissions utilizing sophisticated modulation.

In dense urban environments, technologies such as massive MIMO and beamforming further complicate the identification of unauthorized sources. To maintain spectral integrity, operational teams must reliably detect short-lived or hidden signals within complex environments. This capability is essential when investigating interference reports in critical areas, such as airports or high-profile international events.

You must strike a balance between laboratory-grade performance and rugged portability required for field work. As the spectrum becomes more congested, you must ensure the effective use of limited personnel resources and time while maintaining the ability to capture advanced, highbandwidth signals. Equip your teams in the field with tools that are mobile, without sacrificing the analytical depth needed to protect vital frequency spectra.
