ASTRI uses R & S advanced test solution to verify its TD-LTE Femto base stations

Using Rohde & Schwarz advanced test solutions, the Applied Science and Technology Research Institute (ASTRI) has verified its TD LTE Femto base stations.

In accordance with the new 3GPP specification TS36.141, transmitter and receiver characteristics and receiver performance under fading conditions must be tested. As part of the verification process, the R & S and ASTRI tested the HARQ and timing-advance functionality of the base stations under realtime conditions.

To generate the TD LTE signal, Rohde & Schwarz uses either the R&S AMU200A baseband signal generator or the R&S SMU200A RF signal generator. For conformance testing, the LTE realtime uplink feedback option is now available for both instruments. The Femto base station under test, designed by ASTRI using picoChip's platform, sends a realtime feedback in line with 3GPP specifications to the generator.

Both functions are needed to simulate the correct feedback behavior between the base station and the terminal. In addition, it is possible to determine the current data throughput that the base station achieves under defined fading conditions. This throughput is a measure of the base station's receiver performance.
