Features & benefits

Ground-ground voice assurance

Reachability and voice quality monitoring between centers and towers

The R&S®AVQA ground-ground assurance monitors and stores quality details about each ground-ground call. In the event of problems, automatic impairment recognition immediately alarms the maintenance team with background information on the root cause. In addition, long-term statistics on MOS, reachability and other parameters are the basis for annual reports to civil aviation authorities.

Ground-ground call details

Ground-ground call details

Detailed information about ground-ground streams with low packet interval of 10 ms and tolerable jitter.

Air-ground voice assurance

End-to-end voice and radio system monitoring to ensure safe flights

Monitors functions and quality of entire air-ground communications systems as well as ATC radios. The statistical analysis provides reports on VoIP KPIs in line with ED-136 requirements. In case of impairments, automated indication and alarms with root cause analysis provide important information for further investigations. The system is compatible with any ED-137-compatible radios and VCS systems.

Air-ground call details

Air-ground call details

Clearly structured call details on air-ground calls with indicators and detailed information for every five seconds of each call.

Frequency monitor

Keep track of overall frequency utilization for efficient management

Air navigation service providers must be aware of frequency spectrum availability. The R&S®AVQA frequency monitoring function gives the most efficient overview. In addition, impairments such as long-pressed PTT and SQL drops cause immediate alerts, which helps remedy issues faster.

Real-time monitoring of the individual utilization of each channel provides valuable insights for better adjustment to the particular load.

Radio channel statistics

Squelch and noise power level monitoring

The R&S®AVQA RSSI monitor is a prime example of efficient self-diagnostics. The monitor enables network managers to track the RSSI value at every receiver without additional RF monitoring equipment. This is useful for quickly localizing a faulty receiver or a related issue, e.g. a misaligned antenna.

RSSI statistics

The R&S®AVQA RSSI monitor extracts vital RF performance analytics and summarizes them centrally for a clear overview.

Loopback monitor

Insightful closed-loop monitoring of the entire communications chain

The R&S®AVQA loopback monitor uses patented techniques to check end-to-end voice system functionality. The R&S®AVQA covers the RF aspects of the network and can provide a very broad system view for the network administrator. As the name suggests, the loopback monitor compares different receiver responses to the signal transmitted by the ground based radios.

The loopback monitor compares signal strength and reception delay to spot potential problems.

Non-intrusive monitoring

Probes of R&S®AVQA are connected via TAPs or mirroring ports to the monitored environment. This one-way connection ensures that the monitored environment cannot be influenced. Traffic is analyzed locally on the probes and only summary data (QDRs) are send back to the AVQA manager.
