R&S®PR300 - Elevated spectrum monitoring for mobile network operators

Your task

For mobile network operators, a clean spectrum is the basis of a reliable network. However, with the rapid expansion of 5G and IoT, the risk of external interference has never been higher. These disruptions are no longer just simple signals; they are often complex and hidden within wideband transmissions, directly impacting the network capacity and the connection quality of the end user.

In dense urban areas, where technologies such as massive MIMO and beamforming are deployed, identifying the exact source of a performance drop is increasingly difficult. When a cell site underperforms due to external noise or unauthorized transmitters, your teams must act fast. Failure to detect these signals quickly leads to dropped calls, slow data speeds and ultimately, subscriber churn.

You need to minimize network downtime and resolve interference issues before they affect the end user. As mobile networks grow more complex, you must equip your field technicians with tools that allow rapid troubleshooting without the need for heavy lab equipment. Maximize site productivity and protect your infrastructure’s performance by identifying and eliminating performance killers in the field fast and precisely.
