XCAT-MAIS
Massive-MIMO Air Interface Simulator
- Real-time Multi-cell / Multi-UE Massive-MIMO Air Interface Simulator
- XCAT-MAIS (Massive-MIMO Air Interface Simulator) is a real-time versatile system simulator, consisting of 3G/4G/5G channel emulator and logging/analysis tools that enables system engineers to verify system performance with 2G/3G/4G/5G cells and UEs by generating various field environment consistently and repeatedly in the lab.
Use XCAT-MAIS to
- Perform 2G/3G/4G/5G channel emulation in your lab
- Measure cell performance
- Compare cell performance under your specific criteria
- Algorithm verification such as multi-UE scheduler, FFR, CoMP, IRC, ICIC/eICIC
- System capacity verification in multi-cell/multi-UE, cell edge, moving UE environment
- Package verification prior to customer release
- Troubleshooting with quick reproduction of problems
- Logging and analysis of SINR, RSRP, RSSI, Transmit Power, RB/MCS, Throughput CDF, etc.
- System parameter optimization of RRC, MAC, PHY
