Wireless Interference: Measurements, Common Problems, & Solutions

May 30, 2018 @ 10:00 am - 11:00 am PDT


Finding interference, making the measurement and interpreting the results, are key to successful RF interference hunting. Finding offending signals takes time, patience, and knowledge. It is important to use the right measurement tools to get fast and accurate results. And in many cases, identifying and resolving an interference problem, can have both a technical and political component to it.

In this webinar, we will be discussing the measurement of radio signals, interference issues, wireless receiver sensitivity and data quality (DAQ and BER). In addition, we will address the problem of passive inter-modulation which is a big problem in today’s wireless world.

We will focus on the use of measurement tools including the PR100 Monitoring Receiver and spectrum displays. We will also display examples of common interference issues including, adjacent channel and co-channel interference, radio jamming, inter-modulation and harmonics.

Interference – Common Problems

  • The top five interference issues
  • Noise floors
  • Co-channel
  • Adjacent channel
  • Intermodulation – PIM
  • Harmonics
  • Signal Quality – BER & DAQ

Interference Tools

  • Monitoring Receivers – PR100
  • Spectrum Analyzers
  • Directional antennas
  • Triangulation

Getting Results

  • Safety & making connections
  • Setting the display
  • Measurement of signals
  • Bandwidth – Span – Resolution

Result Interpretation Examples

  • High signal levels & noise
  • Co-channel & adjacent channels
  • Intermodulation
  • Harmonics – high power
  • Jamming – intentional

Recording & Reporting

  • What to record
  • Using Monitoring Receivers & Spectrum Analyzers
  • Proving the point
