Dive into the future with technology that promises to enhance device development for ultra-high-definition video streaming, VR, AR, and beyond, making it useful for next-generation wireless devices.

As the telecommunications landscape evolves with the advent of 5G technology, the integration of non-3GPP networks, including public, home, and enterprise WLAN hotspots, with the 5G core is becoming increasingly significant. This integration is setting the stage for the future of smartphones and other wireless devices, which will depend heavily on advanced WLAN technologies such as Wi-Fi 7. These technologies promise to deliver greater power and efficiency but come with the challenge of increased complexity. 

Rohde & Schwarz unveiled its latest Wi-Fi 7 test solutions to address these emerging needs. These solutions are designed to tackle the growing test challenges associated with next-generation WLAN technologies and their coexistence with existing LTE and 5G standards. This multi-technology multi-channel signalling tester is now equipped with Wi-Fi 7 testing capabilities. This enhancement enables R&D engineers to test wireless devices across both cellular and non-cellular standards using a singular instrument setup, streamlining the development process. The R&S CMP180 radio communication tester will be demonstrated, verifying signal waveforms of 480 MHz bandwidth in loopback mode. This capability not only meets but exceeds the current requirements for Wi-Fi 7, proving itself as a future-proof tool for both R&D and production environments.

Key features include:

  • New Wi-Fi 7 capabilities.
  • Tests RF TX/RX characteristics of WLAN devices under real conditions.
  • Supports Multi-Link-Operation (MLO).
  • Flexible across multiple radio technologies for Wi-Fi 7-specific tests.
  • Enables testing of WLAN offloading and Voice over WLAN.
  • Ensures seamless service continuity.
  •  Provides high-quality voice experiences over WLAN networks.

The development of Wi-Fi 7, or IEEE 802.11be, marks a significant leap forward in WLAN technology, aimed at supporting extremely high data throughput for applications like ultra-high-definition video streaming, virtual reality, and augmented reality. Wi-Fi 7 introduces enhancements such as increased channel bandwidth (up to 320 MHz), up to 16 spatial streams, and advanced 4096 QAM modulation. The test solutions are designed to meet these advanced specifications, demonstrating the company’s commitment to supporting the evolution of WLAN technologies. For device production, the tester is optimized for efficient RF measurements in non-signalling mode. It supports a wide range of cellular and non-cellular technologies, including Wi-Fi 6E, Wi-Fi 7, and 5G NR FR1, with bandwidth capabilities up to 500 MHz. Its ability to verify a 480 MHz WLAN waveform positions it as a forward-looking solution for both R&D and production needs.
