Logging and Measurements
Selective logging and display of all layers of 3GPP LTE and NR stacks as well as useful graphs and analytic tools.
Automatic Test Setup and Scripting
Extensive WebSocket API allowing to send remote commands to eNodeB, ng-eNodeB, gNodeB, EPC and 5GC to ease test automation.
Easy Configuration
Easy configuration thanks to JSON files with example configurations already included in each software release for eNodeB, ng-eNodeB, gNodeB, EPC and 5GC.
End to End Data Testing
Running on top of standard Linux in user space mode allowing easy integration with IP services.
Channel Simulation
Simulation of different DL channel types as per 3GPP models specified in 36.101 and 38.141 specifications. Simulation of NTN channels (delay and doppler) for GEO, MEO and LEO constellations.
Feature testing
Test features to override the nominal protocol behavior in order to simulate error cases.
High Performance
Highly optimized software supporting multiple UEs and cells and high data rates in LTE and NR.
3GPP Features
Early access to 3GPP features for rapid validation of features under development.
Frequency Agnostic
Support of a wide range of FDD and TDD frequency bands even nonstandard ones allowing to test in Sub-6GHz and mmWave. mmWave available on the AMARI Callbox Advanced, Ultimate and Extreme as an option.

AMARI PCIe SDR 2x2 Card
AMARI PCIe SDR 2x2 is a software defined radio (SDR) card using AD9361 2x2 RF transceiver. It supports MIMO 2x2, FDD and TDD operations in any frequency between 500 MHz and 6GHz. It has an integrated GPS for precise time and frequency synchronization. The cards can be easily chained thanks to a provided cable allowing clock and PPS propagation in between the cards. This will facilitate testing of higher MIMO layers and carrier aggregation. The total bandwidth of the card is 56 MHz, and its output power is around 0 dBm depending on the used frequency. The card requires at least gen 2 PCIe slot. This RF is used in AMARI Callbox Mini, AMARI Callbox Classic and AMARI UE Simbox LTE Series products.
