MIMO Test

A challenging antenna technology, MIMO (Multiple Input, Multiple Output) is improving spectral efficiency (bit/sec/Hz), signal quality and cell coverage. MIMO is being used in multiple technologies including LTE-Advanced, WLAN and now being heavily investigated for new 5G technologies. Being a complex technology and an evolving standard for multiple technologies, MIMO provides hidden roadblocks and requires its own suite of measurements. Keysight's solutions are ready to enable deeper insights, especially as the standard evolves. In design and test, Keysight's solutions support innovation across new and existing technologies and allows engineers to transform ideas into reality.
