Test Background 

According to the feedback from the staff of the network optimization department of an operator, several 5G base stations in Jinnan area of a city have been interfered by unknown interference sources since the station was opened. The interference information extracted in the background is shown in the figure below. The statistical interference signal bandwidth of different base stations occupies about 20 RBs. , the interference frequency band is consistent, it can be presumed to be the same interference source.

Test process one:

Use the gated scanning function of the 5G NR monitoring analyzer, synchronize with the base station through GPS timing, and lock the uplink time slot for interference investigation, respectively neverCheck the same site and find a signal at one site, and the signal strength is about -100dBm.

Test process two: 

Through continuous approximation and search, the interference source is finally identified as a roadside camera backhaul device of a public security system, and the interference waveform is consistent with the background network management test waveform.

Summary:

Since the simulation base station used the spare frequency band as a 4G public security base station before, but this frequency band has been officially authorized for mobile use, so the public security simulation base station needs to be frequency-shifted. and so on.

Other Cases

5G NR monitoring analyzer is mainly to cope with the current latest 5G NR communication system to provide a complete test of the million cases. It provides efficient test methods and means for spectrum analysis, interference exclusion, base station testing, road coverage and other testing needs, and is a necessary tool for projects such as base station opening verification and network quality improvement projects.

Detail

An operator in the vicinity of three base stations in the Division Court district there is round-the-clock interference, resulting in complaints from neighboring 5G users perception problems, through the background network management to detect PRB noise value, found 2515-2535MHz lift, due to the three base stations are the strongest interference in the sector of the cell, the preliminary analysis for the existence of interference equipment in the small area.
