IEEE 802.11ax is intended to improve the user experience and network performance in dense deployments in the unlicensed bands. Explore the technology and get an overview of receiver and transmitter test requirement. Learn about the main goals and features of IEEE 802.11ax, the high efficiency PHY, and test requirements.

With advances in digital signal processing techniques modern wireless communications systems and radar systems have become increasingly digital and more constraints have been placed on packing more information into less and less bandwidth. On the wireless side, modulation formats have become more complicated with less margin for symbol error.

This white paper examines everything from lab-based testing and in-field performance testing to over-the-air (OTA) testing needs for vehicles. In the end, a clear overview of supplementary, non-communication related testing aspects in the automotive world is offered.

Employs the latest generation of the R&S CMX500 wideband radio communication tester, combined with the labCORE hardware platform from HEAD acoustics and their ACQUA measurement and analysis software. 

Most ADAS functions rely on radar sensors, and these safety-critical components must function correctly even under the most demanding of RF environments. We have released a white paper describing a test procedure to replicate real life scenarios where the ADAS radar functions are activated during EMS testing and it contains some very interesting results.

R&S®GSASLP is a satcom analysis and optimization software solution, covering all aspects of modern satellite communications. R&S®GSASLP perfectly supports major parts of the satcom value chain such as satellite system design, transmission planning and transponder usage optimization. R&S®SLP accurately models weather conditions, atmosphere effects and covers all RF transmission impairments of transparent payloads among all satcom bands of interest (C, X, Ku, Ka band etc.).

The Rohde & Schwarz®FSWP (FSWP) is a modern, digital signal processing based, phase-noise test set that performs many tasks in parallel in an effort to improve measurements speed. However, several measurement settings drastically affect measurement speed. This paper will discuss these settings and provide suggestions on improving overall measurement speed.

This application note belongs to a series of application notes which explain how to test EW receivers at RF in the lab with commercial, off-the-shelf signal generators and software. The series will cover all relevant use cases. This application note will discuss the generation of radar signals in a hardware in the loop (HIL) environment with PDW streaming.

Engineers often need to test the direction finding capabilities of radar warning receivers in the lab. A perfect solution is to use multiple coupled R&S®SMW200A vector signal generators that are phase-coherent and time-synchronized. This setup enables simulation of the angle of arrival (AoA) of radar signals in the lab.
