To address our rapidly approaching, hyper-connected future and the unprecedented demand on current 4G wireless networks, researchers at the University of Bristol and Lund University set out to test the feasibility of massive MIMO as a viable technology for 5G networks. Using the NI MIMO Prototyping System, the team was able to rapidly test new ideas on their way to implementing the world’s first live demonstration of a 128-antenna, real-time massive MIMO testbed and set two consecutive world records in spectral efficiency.
With the modern mobile device revolution, semiconductor suppliers are challenged to increase capability, integration, and performance while reducing time to market. Test needs a new approach based on an open, flexible platform at significantly lower cost. NI is bridging this gap by building on the stability and capability of the PXI platform to deliver off-the-shelf modular technology to both the characterization and production engineer.
Today, at the IEEE Wireless Communications and Networking Conference (WCNC) in San Francisco, National Instruments (NI) publicly demonstrated a real-time, over-the-air prototype aligned with the Verizon 5G specification. The 28 GHz system uses OFDM with eight component carriers in a 2x2 downlink MU-MIMO configuration, with hybrid beamforming and a self-contained subframe, yielding a 5 Gbps peak throughput that is scalable to over 20 Gbps with eight MIMO streams.
The power amplifier (PA) – as either a discrete component or part of an integrated front end module (FEM) – is one of the most integral RF integrated circuits (RFICs) in the modern radio.

The quest for highly efficient 5G wireless connectivity has been given a boost thanks to a collaboration between a team of 5G engineers from the Universities of Bristol and Lund, National Instruments (NI), and BT Labs, one of the world’s leading providers of communications services. The research team has undertaken field trials of a massive MIMO system at the BT Labs in Adastral Park, Suffolk. The trials were conducted in a large indoor hall mimicking a stadium environment and outdoors within the Adastral Park campus.
NI announced the availability of the USRP-2945 quad receiver software defined radio (SDR) and the USRP-2944 high performance 2x2 multiple input, multiple output (MIMO) SDR. Both models deliver a new level of performance and capability to the USRP (Universal Software Radio Peripheral) family.
NI AWR Design Environment Version 13 now offers an improved flow between AWR Connected™ for Sonnet® and Sonnet Suites Version 16.54 using the latest EM Socket II architecture, which streamlines design flows between NI AWR software and third-party electromagnetic (EM) tools. The new partner flow boasts 64-bit compatibility, as well as asynchronous EM simulations.
Version 13, the first major update in 2017 to NI AWR Design Environment, has been released. V13 provides key new capabilities and major enhancements to better address the design challenges associated with highly-integrated RF/microwave components commonly found in communications, phased-array radar and other electronic systems.
