6G ISAC

Integrated sensing and communication (ISAC) is a key 6G technology component that transforms mobile networks from basic communication systems into spatially aware platforms. Historically, communication and radar applications were studied, developed and commercialized separately. ISAC is a unification of the two. It uses the same radio signals, infrastructure and hardware for both communication and sensing, offering high-speed data connectivity while functioning as an intelligent radarto detect, locate and track objects in real time.

A network that is natively aware of its physical surroundings enables a wide range of advanced applications, such as:

  • Aerial traffic management: Detects and classifies drones or uncrewed aerial vehicles (UAV) and/or enables efficient communication for collision avoidance
  • Industrial automation: Tracks robotic equipment and enables robot communication to ensure safety and improve factory efficiency
  • Traffic monitoring: Traffic density estimation, speed estimation, direction estimation, lane-related localization and detection of critical situations such as wrong-way driving or hazardous objects on railways

ISAC increases overall efficiency as communication and sensing utilize the same spectrum, and signals are transmitted and received by the same hardware. In other words, the same spectrum and signals are used for both purposes. This leads to opportunities and challenges from a testing perspective.

Rohde & Schwarz actively participates in research and implementation projects. We are actively involved in both national and international 6G research and pre-development projects, working alongside renowned institutions to develop the relevant test solutions. For example, we are a partner for the 6G SENSATION Project (funded by the German Federal Ministry of Education and Research).

6G ISAC testing challenges

Integrating sensing and communication into a unified framework introduces higher system complexity. Comprehensive and precise measurements are crucial to evaluate the performance and efficiency of an ISAC system. In particular, verifying sensing performance is new to the field of wireless communication. It requires ground truth knowledge of real physical objects used in a verification process or the capability to emulate objects with defined parameters such as distance, speed and radar cross section (RCS). RCS is the amount of signal energy reflected by an object, and it is fundamental to a reliable and reproducible verification process covering a large parameter range.

Another important topic for object classification is micro-Doppler. The Doppler effect causes a moving target to shift the frequency of the radar return. However, few targets are truly rigid bodies. Most targets having moving components, and these localized motions introduce secondary frequency shifts - or micro-Doppler effects - that can be used for target classification and identification.

Our innovative test solution for 6G ISAC

Rohde & Schwarz offers a laboratory test platform for verifying ISAC technology. This platform is based on the R&S®AREG800A radar echo generator for object simulation and can be augmented with the R&S®FE44S external frontends . This solution enables reliable and repeatable tests in the lab, accelerating ISAC implementation R&D and paving the way for industrial deployment. It is complemented by our broad portfolio of wireless communication testers for validating wireless devices and ISAC applications.

Rohde & Schwarz was awarded the GTI Award for Innovative Breakthrough in Mobile Technology at Mobile World Congress 2023 for its innovative ISAC testing concept.
