Networks and communication facilities parameters measuring system.

The system Corund is designed for automated measurements of the communication facilities and networks. The system can be used in controlling the communication quality of service, measuring the coverage area, seeking the interference sources, also in electromagnetic environment analysis, and e stimation of the connection duration.

Features

Case-packed compact system with a built-in GPS-receiver and IBM-compatible computer (Notebook)
Test terminals for the standards GSM900/1800 (the others like CDMA2000,W-CDMA (UMTS), TETRA, DAB are optional) are used.
One, two, three or four test terminals are available.
Agilent Technologies or Rohde&Schwarz measurement equipments can be used
Position location using the system GLONASS/GPS
Automated measurements
Measurement of the main network parameters in standby or connection mode
Measurement of the main parameters of the signals
Base station testing mode to fi x the cell margin
Tabular and graphic display of the information in real time
Real time display of the selected parameters at the digital map of the area
Storage of the data into database.
Statistical post-processing of the data is possible (network access, connection quality, connection setting time etc.).
Power supply: self-contained, or DC (12 V) or AC main circuit.

Capabilities

Simultaneous measurements in different networks

The complex Corund allows concurrent measurements for several networks of different standards, or for several types of test terminals or antennas.

System configuration

Combination of measuring facility and test terminals in the complex enables an effective control of communication networks. Different combinations of the equipment are available:

Test terminal/terminals
Measuring receiver/spectrum analyzer
Test terminal/terminals and measuring receiver/spectrum analyzer

The intelligent capabilities of the test terminals (i.e. their ability to seek automatically the network service channels) is used by the complex.

Software

Except the test and measurement equipment, the complex also includes special software, which substantially expands the system capabilities. The software provides a single intuitively obvious user interface for all the standards supported. The main parameters of the signals and networks are displayed in real time mode. The digital map allows displaying the current location of the complex and the receivers, and some network parameters measured. Interaction with the database frequency assignment enables both fixing the communication problems and identifying their sources.

The software enables to display the data in different modes as follows:
