Becker Nachrichtentechnik (BNT) is revolutionizing the testing of mobile and wireless communication systems with its state-of-the-art Air Interface Emulation solutions. By bringing real-world testing scenarios into controlled laboratory environments, Becker RF enables reproducible and reliable results, ensuring compatibility and performance in increasingly complex communication systems.
Why Air Interface Emulation Matters
Testing communication systems in the field is necessary but cumbersome and expensive. Often testing has to be transferred to the laboratory, 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.
Becker Nachrichtentechnik offers various models, targeting typical situations even with more than two communication terminals involved (hand-over testing, V2X scenario testing). The use of state-of-the-art simulation technologies allows for the realistic reproduction of test scenarios and the conduct of extensive compatibility tests. This approach optimizes and automates the testing processes to reduce the time involved.
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. The AIE-X and AIE-W series offer unparalleled capabilities for emulating radio fields, ensuring optimal performance in various test scenarios.
AIE-X Series: Advanced Handover Testing
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).
Key Specifications:
- Frequency Range: 500 MHz to 9000 MHz
- 4x4 full fan-out ports (4 Inputs, 4 Outputs)
- Fine attenuation resolution of 0.25 dB
- Port load capacity up to +33 dBm
- LAN and USB interfaces for seamless integration.
AIE-W Series: Car-to-X Emulation
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).
Key Specifications:
- Frequency Range: 500 MHz to 9000 MHz
- Models with 5 ports (AIE-W5LR) and 8 ports (AIE-W8LR)
- High attenuation range up to 127.0 dB
- Trigger input and remote control capabilities.
