XCAL-ART
Massive-MIMO Air Interface Simulator
- Real-time Multi-cell / Multi-UE Air-Interface Simulator
- XCAL-ART is combination of Accuver’s innovative tools likes of XCAL-MTS + AIS + RPT-Gen + Automation. 1) XCAL-MTS supports real-time load and capacity test with flexibility and reliability for users. 2) AIS (Air Interface Simulator) offers user handover performance test under multi-base stations environment by controlling multi-UEs. 3) RPT-Gen creates user friendly report by automated analysis algorithm. 4) Automated regression testing solution can use time efficiently than manual regression testing. Introduction of XCAL-ART will improve your life with high efficiency of usage of lab hardware, software and human resources and delivers results in a fraction of time.
Use XCAL-ART to
- System capacity verification in multi-UE, cell-edge, moving UE environment
- Package verification prior to customer release
- Logging and analysis of SINR, RSRP, RSSI, Tx Power, RB/MCS, Throughput, etc.
- Troubleshooting with quick reproduction of problems
- System Parameter optimization of RRC, MAC, PHY
- Multi-UE Handover/Cell Reselection testing using AIS
- Repeat testing per each test case using automation scheduler
- Automatic analysis using RPT-Gen, applying algorithms per test case
Benefits
- Real-time simulation and logging in the lab
- No need for drive-test and on-site for cluster preparation
- Efficient use of resources
- Test environment for user-defined test scenarios
- Group operation for multiple tests at the same time
- Perform test cases automatically without control by a user (Automation)
- Provides automatic analysis of event call
-
Benefits of “Real UE Test”
- Good for Reproduction Test of call drop/fail/issues
- Easy to analyze detailed causes of call events
- Able to test the Real Actions of Mobiles (Data throughput, Call performance, reaction to Rx change, etc)
- Easy to use functions for testing Handover of Multi Cells
- M to M (Call between mobiles) test
- MOS (Voice/Video) and Video streaming test
