What does radio verification mean?

With the service Radio Verification NC SYSTEMS offers a package for the preliminary verification of a possible new TETRA location, a changed antenna configuration. A test antenna is brought to the planned height (e. g. by means of a lifting platform), which is fed by a TETRA test transmitter. With the help of a mobile TETRA scanner (TSMx from Rohde and Schwarz and the software ROMES), the expected coverage area is measured. In addition to the field strength level (InBand Power), the decoded RSSI, LA and signal quality parameters (e.g., bit error rate, signal-to-noise ratio or delay spread, just to name a few) can also be evaluated.

Since the test signal differs only by the frequency and the defined Location Area Code (LA) tests in combination with already operating TETRA base stations are possible The expected operating range of the new TBS is already measurable at this early planning stage. Likewise, defined coverage criteria (for example GAN requirements, Best Server demarcation, signal quality) can be recorded and documented.

To record an existing radio coverage, the measurement can also be carried out without a test transmitter. The system technology used is calibrated. The measurement data generated by NC SYSTEMS can be combined or compared with other measurement data that meets the measurement concept of the BDBOS, not limited to.

Application areas:

Existing network admission; Test transmission with measurement data recording; Location aptitude test;

NC TMS Radio Verification Service:

This service include: aTETRA test transmitter agreed standard transmitting antennas, an equipped measuring vehicles test drive documentation in electronic form (including the available * rscmd data). On request data inESRI Shape format are available. The service is also available as a pure “Drive-Test Service” (without test sender) for the evaluation of existing TETRA radio networks. Measurement protocols and calibration certificates can be provided upon request.
