Interference Hunting in mobile Networks

RS Interference Locator15 January 2018 - Unwanted transmitters are pervasive in today’s mobile networks. They degrade network capacity and subscriber QoE, making interference hunting a key issue for mobile network operators and regulators. The new handheld R&S MNT100 RF interference locator from Rohde & Schwarz uses receiver technology and intelligent processing to quickly detect, analyze and locate even complex pulsed interference signals.

The R&S MNT100 RF interference locator from Rohde & Schwarz provides a new, expert approach to the challenge of locating and identifying sources of RF interference in mobile networks. The new handheld instrument is optimized to detect, analyze and locate sources of interference from 600 MHz to 6 GHz. Easy to use, it automatically locates interferers significantly faster than existing solutions on the market by using a realtime FFT receiver and fast automatic direction finding. The R&S MNT100 further enhances the extensive mobile network testing portfolio from Rohde & Schwarz for interference hunting that includes spectrum analyzers, PIM testers, scanning receivers and direction-finding antennas and software.

Extensive feature set as standard

The wide-ranging RF preselection allows the R&S MNT100 to be used with antennas in dense spectrum environments. Under such demanding conditions, the R&S MNT100 makes it possible to detect very low-level signals thanks to its exceptionally high spurious-free dynamic range. It also features the fastest realtime signal processing in its class and, thanks to its fast gap-free realtime FFT, can detect extremely short emissions. Even signals that are transmitted for 20 ns are detected with 100 percent probability of intercept (depending on signal level).

The instrument’s polychrome display enables resolution of superimposed pulsed signals, making it possible to detect and differentiate complex signal bursts that cannot be seen with traditional swept-tuned spectrum analyzers.

Optionally, an innovative handheld dual-mode antenna (R&S HE400CEL) featuring normal or delta mode can be used for accurate manual direction finding. Moreover, adding a magnet-mounted direction-finding antenna with the PC-based R&S MobileLocator software to the R&S MNT100 enables fast automatic direction finding.

The R&S MNT100 is available in various RF interference locator packages: a standard locator package for manual handheld interference hunting, an automatic locator package for automatic mobile direction finding and the complete locator package comprising basic and automatic locator equipment.

Wide-ranging expertise in interference hunting

Thanks to decades of experience in the field and leading-edge technology in spectrum monitoring, site installation, troubleshooting, QoS/QoE testing and analysis, Rohde & Schwarz mobile network testing solutions for interference hunting allow network operators and service companies to monitor, identify and locate any source of interference in mobile networks quickly and efficiently.
