The 3GPP Standard MIMO-Radiated Two-stage Test System
MIMO-Radiated Two-stage Method
Radiated Two-stage Method is one of the test methods defined in 3GPP.
Using amplitude and phase patterns gained from active antenna, execute throughput test in the spatially stable and accurate environment under integrated channel models.
Compared to Multi-Probe method, it requires low level investment of test equipment and the operation and maintenance is as simple as SISO test system. Test speed improves several times faster than multi-probe method.
Characteristics
- Radiated two-stage method
- High accuracy and repeatability
- Full operation automation (single step)
- Ideal tool for both certification and R&D
FAQ
Q1. What is the MIMO Radiated Two-Stage Method?
The MIMO Radiated Two-Stage Method evaluates MIMO performance in two stages by first measuring the device’s antenna characteristics and then using the measured data for wireless performance testing.
Q2. How does the MIMO Radiated Two-Stage Method work?
The first stage measures the device’s radiated antenna characteristics. The second stage applies the measured antenna data and wireless channel conditions to evaluate MIMO communication performance.
Q3. Why is the MIMO Radiated Two-Stage Method used?
The method enables the antenna characteristics and communication performance of MIMO devices to be evaluated in separate stages, supporting MIMO performance assessment under defined wireless conditions.
