Monitoring 5G Interference Issues In The Field

Diagnosing 5G network performance problems requires field measurements of the occupied spectrum, while analyzing the frequency range for co-channel interference, side-band interference, adjacent channel interference, and intermodulation effects. These issues may present as downlink interference at the base station or user equipment, uplink interference, or external interference from competing RF communications signals, unlicensed operation, or equipment failure.

Quickly identifying sources of interferences requires a measurement system that identifies interfering signals in three dimensions: frequency, power, and time. A real-time spectrum analyzer (RTSA) uses color-coded display techniques to show trace intensity, which helps differentiate interference from operations signals. Unlike traditional spectrum analyzers which tend suffer from dead time is unpredictable due to slow sweeping speed, spectrum analyzers with RTSA utilize snapshot fast Fourier transform (FFT) techniques to simultaneously sample, compute, and process data. This simplifies investigation of 5G interference issues in the field.

5G Interference Monitoring Solution

Monitoring 5G networks for interference requires an RTSA-capable signal analyzer that can handle bursts and pulsed signals, while avoiding dead time which can cause missed signals. Keysight portable handheld analyzers combine the functions of a spectrum analyzer, RTSA, cable antenna tester, vector network analyzer, and independent signal source with the addition of a directional antenna to help you detect, locate, and remediate interference issues in the field. This solution supports a maximum bandwidth of 120 MHz and frequency up to 54GHz, making it ideal for 5G interference hunting. Remote analysis software enables operators to sample, monitor, and analyze spectral performance without rolling out a truck for every service call.
