The Amarisoft UE simulator presents an optimal solution for conducting both functional and performance testing in 4G and 5G networks. Functioning as a 3GPP compliant LTE, LTE-M, NB-IOT, and 5G SA/NSA UE, it excels in simulating numerous UEs simultaneously within the same spectrum. The UE Simbox Infinity's scalable solution enables N servers to be interconnected expanding UE simulation to tens of thousands of UEs across tens of cells.
The AMARI UE Simbox Infinity stands out as the most capable in the AMARI Simbox lineup. Each instance is tailored exactly to customers needs. Specifically, because the software is scalable, it can simulate tens of thousands of UEs. Single-server hardware can support up to 5000 UEs across 8 cells, each cell having 100MHz bandwidth and MIMO4x4. Multiple servers can be deployed (currently up to 12) to increase capacity to 60 thousand UEs - and with each server another 8 cells can be tested. It is designed not just for testing single basestations, but partial or entire networks. It is also possible to partition a larger UE Simbox Infinity so that multiple users can use the same Simbox concurrently. Furthermore, support for 5G NTN can be added as a software option, and both 5G FR2 software and hardware options are also available.
The AMARI UE Simbox emulates multiple UEs supporting 5G standalone mode (SA) . 5G Non Terrestrial Network (NTN) and 5G Reduced Capacity (RedCap) are also supported.
The AMARI UE Simbox emulates multiple UEs supporting LTE and LTE-A. Support for emulation of multiple LTE-M UEs.
The AMARI UE Simbox emulates multiple UEs supporting NB-IOT category NB1 and NB2.
The AMARI UE Simbox emulates multiple UEs at different locations for both NR-NTN and NB-IoT-NTN. The channel simulator included can simulate NTN delay and doppler on the basis of SIB19 / SIB31.
Depending the AMARI UE Simbox platform, and the eNodeB/gNodeB configuration, it can emulate up to 60000 concurrent active UEs.
Depending on the AMARI UE Simbox platform, and the eNodeB/gNodeB configuration, the product can deliver up to 100+ Gbps in downlink and 100+ Gbps in uplink.
Intra and Inter eNB/gNB handover are supported.
The AMARI UE Simbox can aggregate multiple TDD and FDD LTEor NR FR1 cells for high throughput testing.
Thanks to our partner Simnovus add-on, the AMARI UE Simbox support VoLTE and VoNR.
Selective logging and display of all layers of 3GPP LTE and NR stacks as well as useful graphs and analytic tools. Log example
Extensive WebSocket API allowing to send remote commands to UE Simulator software to ease test automation. Tutorial
Easy configuration thanks to JSON files with example configurations already included in each software release.
Running on top of standard Linux in user space mode allowing easy integration with IP services.
Embedded traffic generator provides a controlled environment for reproducible results as well as a variety of traffic types such as TCP, UDP and HTTP.
On the downlink side, depending on the simulated UE path loss, the channel simulator modifies the PER of PDSCH and PDCCH and updates measured RSRP/CQI and modifies the uplink signal level accordingly. NTN varying delay and doppler are also supported. Tutorial

AMARI PCIe SDR 100 4x4 is a software defined radio (SDR) card based on AD9371 2x2 RF transceivers. It supports MIMO 4x4, FDD and TDD operations in any frequency between 400 MHz and 6GHz. It has an integrated GPS for accurate 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 100 MHz, and its output power is around 12 dBm depending on the frequency used. The card requires at least gen 3 PCIe slot. This RF is used in AMARI Callbox Advanced, AMARI Callbox Ultimate, AMARI Callbox Extreme, AMARI UE Simbox E Series, AMARI UE Simbox MBS Series and AMARI UE Simbox Infinity Seriesproducts.

The software employed across all AMARI UE Simbox Series products remains consistent. The primary differentiators among the Simboxes lie in the hardware specifications, encompassing factors like CPU power and the number and type of SDRs. These variations translate into differences in capacity, spanning parameters such as the number of cells, cell bandwidth, MIMO layers, and the quantity of emulated UEs.
