National Instruments presented at the last Mobile World Congress 2017 held in Barcelona the latest developments in the field of 5G communications, microwave and software-defined instrumentation. NI is a reference in the development and testing of massive MIMO systems together with the University of Lund and Bristol have managed to make base antennas with up to 128 antennas which transmit 5G signals The massive MIMO system operates at a carrier frequency of 3.5GHz and supports connectivity Simultaneous wireless to up to 12 clients from a single antenna. Each client shares a common 20MHz radio channel. Complex digital signal processing algorithms unravel the individual data streams in the spatial domain seen by the antenna array.
The growth of 5G
The new 5G networks are getting closer to becoming a reality for consumers. NI, as a party involved in the creation of 5G standards, offers testing and testing tools for the definition of these standards. NI's mmvawe technology allows chip developers and ecosystems to perform simulations and tests at high frequencies such as 73GHz on which new standards will be defined.
NI-RFmx 2.2 measurement software for 4.5 G testing
The latest version of your advanced measurement software for PXI RF test systems. When used with the second generation PXI Vector Signal Transceiver (VST), engineers can test 4,5G and 5G RF components such as transceivers and amplifiers using a wide range of carrier aggregation schemes, although the 5G standard is still being defined. With the second generation VST, engineers can simultaneously generate and measure up to 32 LTE carriers, each with 20 MHz of bandwidth, and use the software to specify multiple carrier space schemes.
