For many years the telecoms industry has had good support for PIM test with IEC62037 compliant test solutions.
Unfortunately, these PIM test solutions can only test a single RF band and require the cell site to be out of service for the duration of the test with the need to climb the tower and disconnect RF cables.
Modern telecoms networks suffer from increasing PIM problems due to ever-more-crowded RF bands, higher system loads and cross-sector PIM. AceAxis has developed a unique patented technology to address PIM testing in complex multi band 4G and 5G networks that is entirely passive and can measure PIM whilst the cell site is operating with measurements taken from the tower base or BBU hotel.
AceAxis PIM Detection products can accurately measure and locate PIM in live cell sites using a small portable test box that can be left at the cell site for long-term monitoring if needed. Using an uncomplicated GUI and easy to follow instructions we have simplified the test process to ensure that complex test conditions are easy to check quickly and cost-effectively.
AceAxis PIM Detection at its heart is a software algorithm processing I/Q information on the front haul interface. AceAxis has ported its IPR to multiple platforms. These platforms will enable even more PIM capability to be provided for example root cause analysis of PIM, estimation of potential PIM Cancellation, possible and predictive modelling of the potential for PIM at the cell site.
