Test Solutions for Mobile and Wireless Communication

Emulation of Air Interfaces

Testing communication systems in the field necessary but cumbersome and expensive. Whenever possible the testing has to be transferred to the laboratory environment, in order to achieve reproducible and reliable results. Emulating the propagation of the signals over the air can be achieved by using air interface emulation devices connected to the communication systems in conducted mode, modifying the physical channel on RF level: amplitude, phase, delay. BNT offers various models, targeting typical situations even with more than two communication terminals involved (hand-over testing, V2X scenario testing).

Cost Optimization

The deep integration of radio networks into our daily lives has led to a continuous increase in the complexity of devices, not least due to the ongoing development of mobile communication standards. In particular, the expansion of the use of mobile communication components in vehicles contributes to enhancing driving comfort and safety. However, these developments require intensive testing of newly developed components to ensure their compatibility with various transmission standards.

To save costs in the design and qualification phase of mobile communication components, efficient strategies are crucial. One approach is to optimize and automate testing processes to reduce the time involved. The use of state-of-the-art simulation technologies allows for the realistic reproduction of test scenarios and the conduct of extensive compatibility tests.

Becker Nachrichtentechnik offers diverse solutions for the reproducible simulation of radio channels under laboratory conditions. All devices can be conveniently integrated into industry-standard rack systems and can be controlled either through a user-friendly interface or integrated into higher systems through simple SCPI commands.

AIE-X | Air Interface Emulator 

The AIE-X series is an n to n port radio field emulation for generating handover test scenarios. These devices can be used to individually map field scenarios of complex transmission channels such as MIMO. The frequency range of the device extends from 500 MHz to 9000 MHz and therefore also supports the latest WLAN standards Wi-Fi 6E (IEE 802.11ax) and Wi-Fi 7 (IEE 802.11be).

AIE-W | Cellular and Car-to-X Emulator

The AIE-W series is a radio field simulator for Car-to-X applications. Each RF port is designed for bidirectional operation and is connected to each of the remaining ports via adjustable attenuators. The device is designed to operate from 500 MHz to 9000 MHz and therefore also supports the latest WLAN standards Wi-Fi 6E (IEE 802.11ax) and Wi-Fi 7 (IEE 802.11be).
