The real-time testbed includes an FPGA-based LTE physical layer in source code so that different scenarios of LTE-U and LAA can be tested, evaluated and potentially augmented to assess performance and increase data rates for systems built on existing LTE and 802.11 infrastructure.
Because both LTE-U and LAA use the 5.9 GHz unlicensed ISM band to augment the cellular spectrum, LTE-U and LAA capable devices must “share” the channel with WiFi equipment such as 802.11a and 802.11ac. The 3GPP Technical Specifications Group is focusing on LAA because it complies more universally with global spectrum regulations while LTE-U may be rolled out regionally.
Based on the NI USRP RIO software defined radio and the LabVIEW Communications System Design Suite, the NI testbed provides a ready-to-run system composed of the following components:
- LabVIEW Communications System Design Suite
- LabVIEW Communications LTE Application Framework
- Configurable LTE-U and LAA reference software
- Two USRP-2953R FPGA-based software defined radios
