Mobile Interference Hunting System


Anritsu Mobile Interference Hunting SystemQuick. Reliable. Multi-Emitter.

4G network operators have a strong interest in interference reduction driven by their customer’s adoption of an on-line lifestyle. The increasing demand for connectivity anytime and anywhere leads directly to the need to rapidly increase capacity and throughput.

Anritsu’s Mobile Interference Hunter, part of Anritsu’s monitoring and interference hunting family of products, can quickly and reliably locate interfering signals from a moving vehicle, even when there are multiple sources (think of a leaking CATV system) or when there are legitimate uplink signals present. It shines in difficult RF situations. Shadowing, multi-path, and reflections all can be sorted out. Pulsed or bursty signals can also be quickly found.

Key capabilities include:

  • Five minute setup in most vehicles, no need for a dedicated truck or van
  • Multi-Emitter signal location for cases, such as CATV egress, where there are many signal sources.
  • Power-of-Arrival technique combined with averaging sorts out RF multi-path, frequency drift, shadowing, and reflections, allowing users to find the true signal source despite issues that confuse conventional direction finding techniques.
  • Post-capture analysis allows replaying of the drive, with different decision thresholds. This allows expert analysis, or even iterative analysis, of the drive data at a later time.
  • Simplified spectrum clearing, even with the uplink in service.
  • Can reliably locate many pulsed or bursty signals, even ones as short as 200 uS.
  • Uses a small magnet mount omnidirectional antenna for inconspicuous operation.

Anritsu Mobile Interference Hunting System — Quick. Reliable. Multi-Emitter.

Anritsu’s Mobile Interference Hunter is a quick and reliable way to find multiple emitters, or single emitters even in difficult reception conditions. The ability to work with multiple signal sources, reflections, RF shadows, and multi-path distinguish the Mobile InterferenceHunter from conventional systems that depend solely on directional antennas. The ability to work with signals that are intermittent, bursty, or drift rapidly in frequency separate the Mobile InterferenceHunter from more expensive solutions targeted at a single fixed frequency interferer.

The Mobile Interference Hunter is targeted at Multi-emitter sources, such as cable TV egress, signals resulting from equipment faults, intentional interference, and time-variant signals. It even provides a simple spectrum clearing capability.

The Mobile Interference Hunter’s post-capture analysis capability allows users to modify search parameters without re-driving the route. This allows re-analysis of the captured data as well as consulting with experts.

The Mobile Interference Hunter works with the broad array of Anritsu’s handheld spectrum analyzers, providing interference hunting and spectrum clearing capability from 9 kHz to 43 GHz. The Mobile InterferenceHunter is a quick, reliable, and multi-emitter enabled solution to your interference hunting and spectrum clearing needs.

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
  • 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.

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.

Tablet/Laptop Requirements

The mobile interference hunting system work with either the Windows 7 or Windows 8 operating systems. Windows 8 is recommended for its touchscreen capability.

Minimum requirements for Windows tablet/PC:

  • Dual or Quad core processor (> 1 GHz)
  • 2 GB RAM
  • 32 GB onboard memory
  • 1 USB port on tablet (on monitor) - may use OTG cable if a normal USB port is missing
  • Audio Jack

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 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 the Maps page. 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.
