Spectrum monitoring and uplink testing solution for critical communications networks

19 September 2022

Wireless technology solutions provider PCTEL Inc. has launched the SeeHawk Monitor, an automated spectrum monitoring system for P25 public safety radio and other critical communications networks. SeeHawk Monitor also enables automatic testing of the uplink signal, which is the signal from a handset to the radio site, for the purpose of determining that in-building coverage complies with fire code standards.

Interference on the radio network can have life threatening consequences if public safety personnel can’t communicate with incident command or with each other. The SeeHawk Monitor system automatically detects and helps users to identify interference from sources such as other communications networks, bidirectional amplifiers (BDAs) and high-powered industrial systems, so radio network managers can mitigate these sources of interferences to ensure reliable critical communications for first responders.

SeeHawk Monitor users can:

  • Continuously monitor spectrum across multiple radio sites
  • Rapidly detect and characterize service impacting noise and interference
  • Investigate problems with spectrum analysis in real-time or event replay modes
  • Automatically test the uplink signal during in-building coverage testing

The system is easy to install and is scalable to the needs of any network. It is composed of multiple Remote Test Units (RTUs), which monitor spectrum and measure radio signals at each radio site, and the SeeHawk Monitor Platform Manager, which monitors and configures all RTUs in the system.

SeeHawk Monitor’s uplink testing feature makes it easier to ensure high-quality indoor coverage that complies with National Fire Protection Agency (NFPA) and International Fire Code (IFC) standards. The SeeHawk Monitor Platform Manager remotely manages automated uplink data collection on RTUs throughout the network. This enables a tester using a single PCTEL public safety network testing solution to automatically collect uplink and downlink measurements in one survey of a building.
