Emergency Restoration, Maintenance, Path Testing and Troubleshooting

MTSI provides support for cellular, point-to-point, and point-to-multipoint networks by offering maintenance and emergency restoration services. Our maintenance services assure your network will continue to operate as well as when it was first placed into service. However, degraded performance and even service outages may occur over time due to misaligned antennas, lightning strikes, or normal wear and tear. Our field technicians are ready to respond to trouble tickets opened by your Network Operations Center to troubleshoot, repair issues and restore service as quickly as possible.

  • Inspect antennas for damage or misalignment
  • Inspect transmission line and connectors for damage
  • Inspect grounding for damage, theft, or vandalism
  • Check outdoor cabinet or shelter for vandalism and insect infestation
  • Perform VSWR sweep of transmission line and PIM testing of coaxial cables
  • Record radio receive signal level (RSL) , error rate performance, and alarm history
  • . . . and more.

MTSI emergency restoration services includes:

  • 7x24x365 on-call availability
  • Ability to dispatch using nearest available crew
  • Regular progress updates on trouble tickets

The performance of a radio system can be degraded over time from a variety of causes, ranging from hardware issues to radio wave propagation.

Hardware problems may range from loose antenna mounts and misaligned antennas, to moisture in transmission lines, to poor equipment maintenance or failures. Propagation issues may include fading anomalies or frequency interference.

MTSI skilled and experienced technicians use a variety of test equipment to perform tasks that includes:

  • VSWR sweeps of transmission lines
  • Passive Intermodulation (PIM) testing of coaxial transmission lines
  • Bit Error Rate or RFC 2544 testing
  • Evaluate the frequency spectrum using spectrum analyzers
  • Measure fading activity using chart recorders or from RSL history logs within the radio

MTSI’s trained personnel have the expertise to quickly troubleshoot radio paths, diagnose problems, and recommend and implement corrective action.
