The MWT-200 Cellular Network Emulator by MAXEYE Technologies is a universal wireless signaling tester that simulates eNodeB, gNodeB, BTS, Core Network, and IMS Server – all in one compact, bench-top platform for validation of mobile devices based on cellular standards (2G GSM/GPRS, 4G LTE, 5G NR). The Cellular Network Emulator can be used for testing devices such as smart phones, tablets, automotive infotainment, telematics, eCockpit and many other devices. It is a complete integrated solution that supports simultaneous simulation of two networks and parallel testing of multiple User Equipment's (UEs) or mobile devices compared to the traditional single UE testing, adding significant advantages in improving test performance.

eCall/NG-eCall System Architecture

eCall/NG-eCall is a life-saving in-vehicle emergency call system mandated across Europe and adopted globally. Upon detecting a serious road accident, it automatically initiates an emergency call and transmits a Minimum Set of Data (MSD) to the nearest Public Safety Answering Point (PSAP). NG-eCall (Next Generation eCall) extends this over IP-based networks (IMS/4G/5G), enabling richer data payloads, video, and real-time telemetry — making emergency response faster and smarter.

eCall vs NG-eCall

Test Environment Setup (eCall/NG-eCall)

A complete eCall/NG-eCall test environment simulates the full emergency call chain from in-vehicle event to PSAP response without triggering real emergency services. Our comprehensive eCall/NG-eCall Test Suite powered by the NavikEye GNSS Simulator and MWT-200 Cellular Network Emulator delivers end-to-end conformance, interoperability, and performance validation in a single, integrated platform.

• IVS Simulator: Software/hardware unit emulating the in-vehicle system, crash events, and MSD generation.
• Network Emulator: Emulates GSM, UMTS, LTE, 5G network with core network functionality.
• GNSS Simulator: Emulates GNSS satellite signals for vehicle positioning.
• Protocol Analyser: Captures and decodes all signalling (SIP, RTP, MSD) for conformance verification and root cause analysis.
• PSAP Simulator: Receives and decodes emergency calls and MSD, no real dispatch.

Handover Testing

In a real-world a vehicle is rarely stationary. Handover is the mechanism that transfers an active voice session or data connection from one cell tower or radio access technology (RAT) to another — without dropping the call or corrupting critical payload data. Handover testing validates that this transition occurs reliably across all network types, speeds, and signal conditions.

• Intra-Frequency Handover - Transfer between cells on the same frequency band within the same RAT — the most common scenario in dense urban deployments.
• Inter-Frequency Handover - Transfer across different frequency bands within the same RAT, triggered by coverage or load-balancing conditions.
• Inter-RAT Handover - Cross-technology transfer between GSM, UMTS, LTE, and 5G NR — critical for validating fallback behaviour during active eCall sessions.

Test Environment Setup (Handover)

MWT-200 supports comprehensive mobility testing for UEs traversing inter-cell environments. With the help of test suite we can perform Cell Selection, Cell Redirection, and Handover procedures, dynamically adapting to both UE and base station states. RF power conditions are logged and stored as reproducible test parameters — enabling rapid UE behaviour evaluation, systematic failure reproduction, and consistent performance benchmarking across all handover test cycles.

C-V2X Test Setup

C-V2X (Cellular Vehicle-to-Everything) is a state-of-the-art wireless technology used in autonomous driving and intelligent transportation systems (ITS) to extend the blind spot detection. MWT-200 provides an application-level testing of V2X as per the standards applicable in Europe, USA and China. MWT-200 simulates GNSS signal for DUT navigation and synchronization. A scenario creator with user friendly WebUI tests complete stack and application layer messages. V2N, V2V, V2I and V2P communication can be tested continuously. MWT-200 can be used to set up a test bed where any number of real-life scenarios can be configured to test the device behavior in different environments with multiple vehicle simulation.
