Wireless Communications Research Infrastructure
Wireless Communications Research Infrastructure
The Wireless Communications Research Infrastructure enables wide-scale research, prototyping, demonstration and testing of radio communications devices, wireless networks and RF systems. The environment facilitates full-scale 4G LTE/LTE-Advanced and 5G NR mobile test networks, covering all relevant L1/L2/L3 functionalities as well as live core network functionalities, and supports not only data but also VoLTE services. Additionally, NB-IoT technology is available.
The research infrastructure also contains a comprehensive RF measurement laboratory for arbitrary waveform generation and analysis, as well as software defined radio (SDR) based demonstration and prototyping environment for 5G radio access solutions research, including also support for fast real-time digital signal processing in the devices. Signal generation, analysis and measurement capabilities cover frequencies up to 100GHz, and we host state-of-the-art instruments such as Keysight Infiniium UXR-Series Real-Time Oscilloscopes, Keysight M8195A 65 GSa/s Arbitrary Waveform Generator, Rohde & Schwarz FSW85 high-performance signal and spectrum analyzer, NI Vector Signal Transceiver 2, and NI mmWave Transceiver System. The environment supports also true over-the-air (OTA) testing through various beam-steering and directive antenna capabilities.
The research infrastructure contains also a Spectracom GSC-64 Multi-GNSS hardware emulator which can simulate in real time all the four existing and upcoming GNSS constellations (GPS, GALILEO, GLONASS, Beidou) on four simultaneous carrier frequencies using its 64 independent channels. The simulator is capable to emulate the received satellite signals at any selected time and location (or trajectory) on Earth.
