This application brief explains the complexity of testing in millimeter wave and how you can meet those challenges.
With the race to 5G now underway, the wireless research community has embarked on a journey to create the technologies of tomorrow that will deliver unprecedented improvements in network throughput and capacity, enhancements in spectral efficiency, reduced end-to-end latency, and increased reliability and more. Given the limited availability of spectrum and the projected massive number of IoT devices to come online, one of the key candidate technologies in achieving greater spectral efficiency is Massive MIMO. Using the National Instruments MIMO Prototyping System, researchers at the Universities of Bristol and Lund achieved a record breaking spectral efficiency of 145.6 bits/s/Hz with 128 antennas at the base station and 22 single antenna mobile stations over a 20 MHz radio channel which amounts to a 22x increase in spectral efficiency over today’s existing 4G networks. This white paper describes a flexible MIMO prototyping system that allows you to quickly test on mobility, multi-cell operation, cell edge performance, and other research areas.
This paper presents a method for modeling and evaluating a new NB-IoT (Narrowband Internet of Things) system in a combined multi-domain simulation environment. Due to the complex analog and digital components of the communication system, accurate modeling is crucial to understanding system behavior. Realistic modeling examples are used with a new simulation method for an in-depth study of the RF transceivers, advanced modem technology and non-ideal hardware.

This white paper introduces some of the fundamental theory behind beamforming antennas. In addition to these basic concepts, calculation methods for radiation patterns and a number of simulations results, as well as some real world measurement results for small linear arrays are shown. Due to the bandwidths likely to be employed in such applications, a non-standard way of graphical representation is proposed.
