EMSCAN Smart Antennas – Achieve Optimum Performance!
MIMO (multiple-input and multiple-output) is a smart antenna technology to improve communication performance where multiple transmitters and receivers are used to transfer more data at the same time. MIMO technology turns transmitters and receivers into smart antennas where data can be sent and received through multiple signals from different paths and at different times. Customer demand for fast data transfer and higher wireless bandwidths made MIMO applications major focus of the wireless device manufacturers. And for wireless device manufacturers, accurate and fast measurements in the frequency, time and modulation domains are crucial as they will shorten the design cycle times and improve overall product quality and profitability.
The new RFX2 and RFxpert software release 4.0 addresses MIMO testing. This improved RFX2 has the capability of calculating pattern correlation and envelope correlation in multi-antenna systems; these coefficients can be used in calculation of MIMO diversity gain and channel capacity for specific wireless channels. 4.0 release is a major improvement for the RFxpert as it includes a large number of new features including MIMO data, user requested enhancements and substantial accuracy improvements.
Correlation results in a few seconds will speed up development by engineers working on diversity antennas for MIMO applications like LTE. These new correlation results complement RFX2’s existing real-time measurements and display of the very-near-field and far-field characteristics of a multi-antenna system.
