Overview

Anritsu Mobile Interference Hunting System - “Interference Hunting Made Easy”


The key elements are an Anritsu spectrum analyzer, a magnet mount omnidirectional antenna, a Windows® tablet and the MX280007A Mobile InterferenceHunter Software with the following features:


  • Start rolling quicker and find interference faster than any other solution with less than 5 minute set-up, user-friendly operation, and powerful patent-pending software algorithms.
  • Follow direction indicators on map to locate interference source.
  • See a map view showing the driven route with signal strength markers along with position estimates of the interferer all on a dash-mounted tablet PC.
  • Special features allowing users to detect interferers in LTE uplink bands, periodic (or pulsed) signals and wideband interferers.
  • Voice prompts direct the driver to the estimated interference location for safe one-person operation.
  • Utilize a small magnet mount omnidirectional antenna for inconspicuous operation at the desired frequency of interest within the range of the spectrum analyzer.
  • Drive close enough to be within walking distance of the interference to pinpoint the source with our MA2700A Handheld InterferenceHunter Solution with a directional antenna.

Anritsu Mobile Interference Hunting System - “Interference Hunting Made Easy”

Wireless networks today are being impacted by interference that degrades network performance. For wireless service providers, issues such as dropped calls, blocked calls, and data throughput are all impacted negatively by harmful interference. Operators need to utilize the full of capacity of their networks to keep up with demand. Interference must be found quickly with a tool that is fast and simple to use by even inexperienced RF maintenance technicians. The Anritsu Mobile Interference Hunting System delivers on the requirement for fast and simple interference hunting.

 

Using the Anritsu hunting system, one can find the location of many types of interferers over a wide range of power levels in a variety of RF environments, including urban canyons with severe multipath. Adding mobility to direction finding enables more measurements to be collected in a shorter span of time. This enables special averaging techniques to be employed to mitigate multipath and quickly identifies the location of the interferer. 

Using a Windows 7 or Windows 8 tablet, interference hunters are presented with a map containing direction indicators guiding the user to the location of the unwanted signal. Map directions are supplemented by voice prompts to enable one-person operation. The picture below shows the user interface for the Mobile InterferenceHunter™ software, which is utilized as an integral part of the system. The map illustrates the route taken by the driver to locate the interfering signal. Small dot "breadcrumbs" are shown along the path driven, with colors proportional to the signal level. After a sufficient number of measurements are taken, a grey circle (shown in the map below) is drawn to indicate the most probable location of the interferer.

Components of the Anritsu Mobile Interference Hunting

Each Anritsu mobile interference hunting system requires the following items:

  • Anritsu handheld spectrum analyzer with GPS Receiver and USB control (see below table for specific compatible model list)
  • Anritsu Mobile InterferenceHunter™ software and license (A license key is purchased to enable the software. A link for the software download is provided with delivery of the license key.
  • USB A - 5-PIN Mini-B Cable (Anritsu P/N 3-2000-1498 or equivalent
  • Magnet mount omnidirectional antenna (Anritsu P/N 2000-1647-R or equivalent)
  • Magnet mount GPS antenna (Anritsu P/N 2000-1528-R or equivalent. Required only if omnidirectional antenna used does not incorporate a GPS antenna.)
  • Windows® 7/8 laptop/tablet (Windows 8 touchscreen tablet highly recommended)
  • Mounting hardware for Windows tablet (Anritsu P/N 2000-1801-R or equivalent. Mounting kit is recommended, but not required.)
  • OpenStreetMap™ of desired geography downloaded from Anritsu website. Alternatively, Google Maps may be used

For the Anritsu handheld spectrum analyzer, only a GPS Receiver is needed. No other options or firmware upgrades are required.

By utilizing Anritsu’s proprietary interference finding algorithms, the MX280007A software will quickly determine the position estimate of an interfering signal. Once sufficient measurements are accumulated and filtered for multi-path, the MX280007A software draws a circle on the map indicating the position of the interference source. The diameter of the circle becomes smaller as more measurements are taken, providing a higher degree of accuracy for signal localization.

One-Person Operation

To facilitate one-person operation, the tablet PC can be mounted on the dash with audio voice prompts providing direction. Voice prompts can be fed into the car speaker system with an audio cable or via Bluetooth. If Bluetooth is used, care must be taken so that the Bluetooth wireless signals do not interfere with measurements being taken.

With a user interface optimized for Windows touchscreen tablets the MX280007A software is simple to use. Features include:

  • Max Hold to find interferers which show up periodically (i.e. “radar type” signals)
  • Min Hold to find interferers buried underneath the intended signal (ideal for finding signals hidden in LTE uplink bands)
  • Squelch Control to view only signals above a certain threshold
  • Sensitivity settings from Dense Urban to Rural terrain categories
  • Choice of map sources, either Google Maps or OpenStreetMap
  • Zoom In/Out commands for desired street level view
  • Full Screen Spectrum View for better examination and analysis of the spectrum
  • Growing Breadcrumbs of the drive route that indicate higher signal strength as you drive closer to the interference source
  • Single or multiple emitter detection modes make it easy to use for any type of emitter detection application (multiple emitter mode is ideal for locating multiple cable TV interferers)
  • A spectrum clearing mode using channel power measurements that map signals above a certain power threshold
  • Integrated help system for user assistance

The Anritsu Mobile Interference Hunting System works with many existing Anritsu handheld spectrum analyzers that are enabled with a GPS receiver. These include platforms such as Site Master™, Spectrum Master™, BTS Master™, Cell Master™, or LMR Master™. No additional options or firmware updates needed.

The Anritsu Mobile Interference Hunting system is designed to be best-in-class for its interference detection capability and ease of use. No other inference hunting system is as efficient and simple to use with easy set-ups and voice prompts for safe one-person operation.

Applications

The Anritsu Mobile Interference Hunting System is designed to locate interference signals operating anywhere in the frequency band covered by the spectrum analyzer. An off-the-shelf magnet mount omnidirectional antenna whose range covers the frequencies of interest is required.

Some examples of interferers include but are not limited to the following:

Intentional Radiators

  • Cell jammers
  • Improperly installed repeaters
  • Oscillating bi-directional amplifiers
  • Wireless devices working in improper bands
     – Baby monitors
     – Microphones
     – Surveillance Cameras
  • Pirated cell phones
  • Illegal or "black" base stations

Unintentional Radiators

  • External PIM
  • Cable TV systems
  • Fluorescent lighting
  • Arc welders
  • Industrial microwave
  • Industrial RF heaters
  • Outdoor elevator motors
Maps

Maps used for the interference hunting software can be embedded in the application using OpenStreetMap™. Anritsu provides a webpage to aid the user in this process:


Anritsu Mobile Interference Hunting System Maps


Users can choose an already developed map from the selection provided on this webpage. Alternatively, one can develop their own map with OpenStreetMap using the simple to use instructions provided.

Once maps are made, they can then be incorporated into the MX280007A software by dragging the map file on to the interference hunting software application window. Maps can also be added by clicking on the Settings tab at the top of the MX280007A software and selecting Map Source/Open Source Maps.

Alternatively, tablets with cellular modems attached for internet access can download Google Maps for their application.
