Anritsu has developed the first 4x4 MIMO 256 QAM evaluation function supporting all 3CC CA band combinations and strengthening the functions of the company’s Radio Communication Analyzer MT8821C. With this new release, tests of LTE-Advanced DL 3CC CA 4x4 MIMO 256 QAM mobiles are supported with no restrictions on frequency and signal bandwidth combinations. This software update is available from October 26.
The new software complements the built-in LTE-Advanced RF TRx test base station emulation functions of the all-in-one Radio Communications Analyzer MT8821C. When the new 4x4 MIMO measurement software is installed on two synchronized MT8821C analyzers featuring existing LTE-Advanced DL 3CC CA measurement software, engineers can test the performance of chipsets and mobile devise to ensure their designs. By synchronizing two MT8821C instruments with the new software, up to 12 signals can be output for 4x4 MIMO 256QAM measurements to support all DL 3CC CA band combinations.
The explosive increase in rich-content services, such as mobile video on demand, is driving deployment of the faster LTE-Advanced technology by network operators worldwide.
The key technologies for increasing the speed of LTE-Advanced are carrier aggregation, which aggregates several component carriers into one, and MIMO, which uses multiple antennas for communications.
Anritsu launched its DL 4x4 MIMO measurement software in March 2016 and supports evaluation of LTE-Advanced DL 2CC CA 4x4 MIMO terminals with its all-in-one MT8821C. The MT8821C outputs up to 8 independent signals but by synchronizing two MT8821C units using this newly developed software, up to 12 signals can be output for 4x4 MIMO 256 QAM measurements, supporting all DL 3CC CA band combinations.
